PathFinder Version 4.22 User Guide2. COMMANDER SYSTEM OVERVIEWThe 500 Series Commander Intercom is a fully featured Talkback system, usingmicroprocessors and digital techniques to control audio routing and “talkback” functions.Audio routing is performed using an advanced TDM (Time Division Multiplex) digital audiomatrix. Although audio inputs to and outputs from the system are balanced 4-wire analogueaudio, all audio processing is carried out in the digital domain.Use of DSPs (Digital Signal Processors) allows a 384 x 384 matrix to be built up in blocks of6 input/output pairs, or Ports, without the expensive and space hungry need to expand thesystem by the square law factor associated with analogue crosspoint matrices. Moreover,the use of DSPs allows every crosspoint in the system to have individually variable gain.Microprocessor control of the system is implemented using Transputers. These are very fastprocessors, optimised for real-time parallel processing. In addition they have a number ofhigh-speed data-links (20Mbit/s) to allow a distributed multi-processor system to be easilyimplemented.The TDM audio system is a standalone matrix, complete with its own transputer controller.This system may be instructed to break crosspoints, or make crosspoints at a specified gainfrom any of the 384 possible inputs to any number of the 384 possible outputs. Moreover,any output may be instructed to be a mix of a number of different inputs, by issuingsuccessive requests to connect different inputs to the same output.The DSPs are also able to measure the incoming audio levels and thus provide an indicationof the presence of an input; this is particularly useful for non-panel sources.Running in parallel with the TDM audio system is a Talkback control system. This holds allthe information that describes the way the matrix system will work as a talkback. Itcommunicates with control panels to receive information regarding key presses, controlsettings and so on, and then interprets this information into the correct commands to send tothe TDM system. It then instructs the panels to turn on tally lamps as appropriate.The talkback configuration itself is set-up using “PathFinder”. This software runs on a P.C.and allows the user to determine everything from the labels that appear on the controlpanels, through the actions consequent to a keypress (groups, conferences etc.) to howlogic DC inputs and outputs are handled. With the “Rapide” option, many of the facilities maybe changed in real-time - “on-line”.The “database” of information thus set-up is downloaded to the system Talkback Controllerwhere it may be stored in non-volatile memory to provide a standalone system.The control panels themselves are microprocessor controlled. However the talkbackcontroller, not the panel itself, stores the configuration of any given panel. On power-up theconfiguration, determining switch function; display labels etc. is uploaded to each panel. Thisallows any panel in the system to be replaced, without re-programming.Fitting dual TDM controllers and dual Talkback Controllers with an automatic changeoverprovides fault tolerance in the event of a failure. The design allows any single card in thesystem to fail without the entire system failing. In addition, failure of one or more panels willnot cause complete system failure.2.1 Related DocumentsDocument NumberDescription50096604 This Document (PathFinder User Guide)50096601 Commander Hardware Installation Guide50096670 Commander Matrix Technical GuideTrilogy Communications LimitedIssue 1Page 11 of 11

PathFinder Version 4.22 User Guide3. PATHFINDER INSTALLATIONIn this Chapter, you will find information on:• The requirements of the PC which is to run the PathFinder software.• Installing PathFinder for the first time.• Upgrading from an earlier version of PathFinder.3.1 IntroductionPathFinder is a true 32-bit application designed to run under Microsoft Operating Systemsfrom Windows 95 through to Windows XP. There are limitations on the types of downloaddevice which are supported with these different operating systems: these are explained inthe Commander Installation Guide.Essentially PathFinder is a GUI (“Graphical User Interface”) front end to an underlyingdatabase. This database is used to store configuration information in a set of database files(“DB” files). When a configuration is downloaded to a Commander system, the database isread, and information extracted and translated into a suitable format for transmission to thesystem.The visible screens are effectively a view into the database. The views are provided as“forms” that group information into the database in a way that allows specific features to beconfigured in a coherent manner.3.2 PC Requirements (2006)PathFinder requires the following minimum specification of PC:• 1GHz or better CPU speed.• Microsoft Windows 2000 or XP.• 512 MB of RAM. PathFinder is a complex application and memory requirementsshould always take account of other applications which may run simultaneously.• 5Mbytes of free hard disk space, plus approximately 1Mbyte of disk space perconfiguration database required. The absolute minimum requirement is thereforesuggested to be 25Mbyte.• A serial COM port for downloading configuration data to the Commander matrix.Trilogy Communications LimitedIssue 1Page 13 of 13

PathFinder Version 4.22 User Guide3.3 PathFinder File LocationsUnless alternative folders are specifiedduring installation, the PathFinder installwizard will place a set of folders in theProgram Files folder of the PC.• The Pathfinder 4_xx folder directly below the Trilogy folder contains the applicationfiles.• The Db folder contains the “raw” empty database files used to create newconfigurations.• The configurations folder contains the entire database files related to each userconfiguration stored on the P.C.• The lowest level folder Pathfinder 4_xx contains shortcuts to the PathFinderApplication.The Borland folder and its sub-folderscontain the “Borland Database Engine”(or BDE) files. These are related to thenative database format used byPathFinder and are necessary for correctfunctioning of the application.The Windows Start menu will include shortcuts to the application.3.4 Copying a Configuration to Another LocationIf it is wished, for example, to copy a configuration to a floppy disk, the relevant files will befound in the Program Files/Trilogy/Pathfinder folder. All the required configuration files -as named when the configuration was created or saved - with extensions .DB, .MB and.PCF should be copied. If any are omitted, the database will not run from the new location.3.5 Installing PathFinder for the first timePathFinder is provided on a CD-ROM.. Insert the CD into the PC optical drive, and then useWindows Explorer to browse to the setup.exe file. Double click and follow the onscreenprompts.We advise accepting all defaults offered during the installation phase.When the installation is complete, some important changes must be made before usingPathFinder for the first time.

PathFinder Version 4.22 User Guide5.4 General PathFinder MethodologyPathFinder is designed to use the well-accepted Windows methods of data entry:• Double-clicks or right clicks to pop-up context-sensitive menus• Check boxes to accept/reject changes• Hover help• Dialogue boxes to provide information and/or warnings.It is expected that any user familiar with Windows 95 will not have any problem learning veryrapidly how to effect changes to the configuration.The following Chapters therefore concentrate on the features provided and how they may beused. Where any specific philosophy is used to configure forms, these are mentioned in theappropriate Chapter.5.4.1 Saving Changes - Accept/UndoWith the exception of the overview form, as changes are made on a form, they are notimmediately stored in the database. Each form is provided with "accept" and "undo" buttonsthat may be used to save the changes, or abandon them and revert to the previous settings.UndoAcceptNote that when a new form is selected any changes made to the current form areautomatically saved, without having to select the accept button.The Overview form is an exception to the rule. Most forms are graphical views of thedatabase; the overview is a direct on-screen representation of the database, arranged inrows.Once changes have been made to any item in a row, moving off the row will cause the datato be immediately written to the database. This moving away can be realised by selecting adifferent row, or a different form.5.4.2 Hover HelpTo avoid “clutter” on the forms, many items are provided with “hover help”. This means thatallowing the cursor to linger over an item will cause a description to be displayed.

BUILDING A SIMPLE CONFIGURATIONIn this Chapter you will find information on:• Using the PathFinder Overview to match hardware and software• Configuring panel types• Establishing System Names and mnemonics (labels).• Adding keys and targets to control panels.• Downloading the new database to the Commander system.6.1 Using the Overview FormThe default opening view of PathFinder is the Overview Form. This must be completed priorto any detailed configuration and it must match the physical installation of the system. Beforestarting, gather the following information:• The physical assembly of the matrix frame rear connector units. Your system, asordered, may contain the following options,• Transformer coupled (4-wire only)• Mixing camera ports• Misc. I/O (logic) cardsIf any of these are fitted, they should be located and taken into account within the Overviewplan.• Port allocation (i.e. type of port, size of panel, port number)• System names. These are used for reference only, throughout the program• Port abbreviations (mnemonics). These appear on control panel displays and are limitedto 5 characters maximum.For example,1 16 key LCD Studio Director DIR DIR2 24 key LCD Producer A PROD PROD3 4-Wire London LON LONEnter your information onto the Overview, such that a form similar to below is displayed:• Use the TAB key to move across screen to the right• The port or panel type is selected by moving the cursor to the second column (using themouse or keyboard arrow keys) and right clicking in the box shown.

The standard Windows Save dialogue box will bedisplayed.• The default location is within the Program Files/ Trilogy/ PathFinder branch. You mayselect or create an alternative location which is more appropriate• Windows long file names are acceptable and give a better indication of the function ofthe configurationPage 32 of 32 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide6.4 Complete the OverviewContinue the above process until the outline of the system is complete. Any ports that arenot currently in use do not need to be configured at this time.Page 34 of 34 Issue 1 Trilogy Communications Limited

6.5 Assigning keys to Control PanelsPathFinder Version 4.22 User GuideThe overview completed so far merely provides a framework on which to build. The nextstep is to add keys to the control panels, thus allowing basic intercom functionality.• Using the mouse, select the row containing the first control panel in your overview. (Theexample below shows the panel connected to Port 1)• At the bottom of the screen, click on the second tabbed form, labelled "2 Pan Config". Ascreen similar to that shown below is now displayed.To provide basic panel to panel intercom, two key types will normally suffice. These are:• Speak m/m. This allows the current panel to speak to another panel when thekey is held in the up or down position.• The switch code (e.g. m/m) give the action in the up/down positions, mindicates momentary, l indicates electronically latching.As soon as the key is released back to the centre position, the speech route isbroken.• Speak l/m. this key type provides the same function as the previous one, butthe upwards press is electronically latched. The first upward press 'opens' thespeech route: a second upward press 'cancels' the speech route.The speak l/m key thus allows hands free speech to another panel. In all cases,the red lamp adjacent to the key is lit to show that the speech route is open: themicrophone is live.Trilogy Communications LimitedIssue 1Page 35 of 35

6.6 Assigning key typesPathFinder Version 4.22 User GuideUsing the mouse, select one of the above key types. Again using the mouse, apply this keyto the control panel buttons displayed on the buttons closest to the panel displays: the outerbuttons are reserved for other functions. The picture below shows an 8 key panel with speakm/m keys on the top row and speak l/m keys on the bottom row.The full range of available key types is detailed in 0.Page 36 of 36 Issue 1 Trilogy Communications Limited

6.7 Assigning key targetsPathFinder Version 4.22 User GuideMove the mouse cursor over the display area associated with the first key on the panel. Thecursor changes to a list box. This indicates that a further list of choices is available at thispoint. Right click in the display area and a pop-up menu of system ports will be displayed.Use the mouse to select a key target (i.e. another control panel) from the list. Repeat this forother keys on the panel and press the tick () to accept these assignments. The picture belowshows a typical panel with all keys assigned and targeted to other panels.Trilogy Communications LimitedIssue 1Page 37 of 37

6.8 Use of 4-Wire circuitsPathFinder Version 4.22 User GuideFor the initial configuration, an alternative key type should be used. The Speak/Listen l/mkey provides the following functions:• The first upward press gives an electronically latched 'listen' to anincoming circuit.• A second upward press cancels the listen circuit.• An upward press to activate listen followed by a down pressallows the panel to speak onto an outgoing circuit while the key isheld.Select this key type and follow the sequence used previously to assign and target a numberof 4-wire keys.A typical result, this time for a 16 key panel is shown below.Page 38 of 38 Issue 1 Trilogy Communications Limited

6.9 Adding a Quick Response key (QRS)PathFinder Version 4.22 User GuideIf sufficient space is available, the QRS key is a useful addition to every control panel.Under normal circumstances, a yellow lamp next to the associated key and display indicatesan incoming caller. However, if a panel receives an incoming call but does not have a keyassigned to the caller, the QRS key acts as a 'smart' key causing the display to change fromthe default QRS to the name of the caller. The key is then available to reply to the caller bypressing downwards. Incoming calls are stacked on this key in a “last in, first out” sequence.Entries may be removed from the stack without replying by pressing once upwards. Laterversions of PathFinder also include a single entry version of this key (QRS1).6.10 Transferring Configuration to the SystemThe configuration database so far created only exists on the computer. In fact, it can becreated or edited on any PC installed with PathFinder software. In order to transfer thedatabase to the Commander matrix, two steps are necessary:• A suitable COM port on the PC should be identified.• The PC must be connected to the PC port on the rear of the matrix, using the suppliedcable or an exact equivalent.If both of these conditions are met the PC can establish communication with the Commandermatrix and transfer (or 'download') the database into memory located within the matrix.Trilogy Communications LimitedIssue 1Page 39 of 39

PathFinder Version 4.22 User Guide6.10.1 Memory structure within the Commander matrixFrom a practical standpoint, the Commander matrix can be considered to have three areasof memory.• Active RAM. This runs the current, active program and database.• Buffer. This holds a download configuration database prior to it being used actively. Theprocess of transferring a database from the Buffer memory into the Active RAM is termedre-start.• Flash RAM. Four banks of Flash RAM are provided to store configurations within thematrix. These have the following features:• The memory is non-volatile, erasable. Configurations are not lost if the matrix isturned off but they can be erased or replaced from the PC.• They are quickly accessible, again under control from the PC.• Configurations are always transferred via the Buffer RAM, using the re-startsequence controlled from the PC.• Boot from flash. When the system is initially powered, a configuration is automaticallyloaded from a chosen Flash RAM bank.6.10.2 Download sequenceTo start the download sequence:• Click the Download button on the tool barOr,• Select Download to Commander from theCommander pull-down menu.Depending on the size and complexity of the database, the download will take between 15-60 seconds. During this time, the dialogue box below is displayed.Page 40 of 40 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User GuideWhen the download is complete, the Flash RAM/ re-start option box, shown below isdisplayed.This dialogue box allows you to:• Re-start the system. The recently downloaded configuration (shown in the 'New' box) istransferred from the Buffer RAM into the active system RAM.• Save (or write) a configuration into the chosen flash RAM memory bank. Again, it is the'new' configuration which is written to flash RAM• Load (or read) a configuration from a chosen Flash RAM memory bank back into theBuffer menu area. This operation would normally be followed by a re-start.Approximate times for each of these operations are:• Download: 15-60 seconds• Re-start: 5 seconds• Save: 60 seconds• Load: 5 secondsAll of the above are background operations except the re-start, which is disruptive. Once there-start sequence is indicated,• All routes are broken• All panel keys are turned off• All control panel displays are turned off, and then replaced with the new labels.The system is then ready for use with the new database.Trilogy Communications LimitedIssue 1Page 41 of 41

PathFinder Version 4.22 User Guide7. GROUPS AND CONFERENCESBoth Groups and Conferences allow two or more people to speak together. A panel or portmust be a member of a Group or Conference before it can contribute.7.1 What are Groups?Groups are designed for creating communications between a number of panels and/or 4wires where there is a need to control how each source contributes to the group. A typicalexample for creating a group would be for Production or Omni talkback.For example, a Production Talkback group (PTB) may consist of:• Director and PA panels normally speaking onto the group but not listening, with keys ontheir panels to remove themselves from the group for privacy.• The Sound panel would listen to the group with a key to speak onto the group whenneeded.• On the studio floor, 4 wire circuits for the Floor manager and Cameras would bepermanently listening to the group but not speaking.7.2 What are Conferences?The Conference utility allows the user to create a "many to many" communication betweenports within the system. In its simplest form a Conference is a group of panels which havethe ability to speak to everybody in the Conference except himself.When building a Conference, as panels and 4 wires are added, the crosspoint map willgrow. This map shows all the available crosspoints within the Conference and allows theuser to edit the map to block individual crosspoints, thus customising who speaks to whom.Each panel member must have a listen and speak key targeted to the Conference whereasany 4-wire member is automatically listening and speaking to the Conference.Trilogy Communications LimitedIssue 1Page 43 of 43

PathFinder Version 4.22 User Guide7.3 When to use a Group or Conference?The fundamental differences between a Group and a Conference are listed below.Awareness of their particular features and limitations will help when deciding which solutionto use.In summary:• Groups offer more flexibility in controlling how members contribute to a Group makingthem more suitable for configuring applications like Production Talkback.• A Group can have panel members with normally made or normally broken crosspointslistening and/or speaking to the Group.• Tallies function in Groups.• A 4-wire circuit assigned to a Group can be either a listening member only, speakingmember only or both.‣ Conferences offer the ability to block individual members communicating within theConference making this application more suitable for many to many communications.‣ Panels in a Conference only have normally broken crosspoints available.‣ With a Conference it is possible to inhibit any of the crosspoints within the Conference.‣ Tallies do not function in Conferences.‣ A Conference can be globally enabled or disabled from the GUI.‣ A 4-wire circuit assigned to a Conference is a permanently listening and speakingmember.‣ A panel must have a listen/speak key to take part in a Conference.Page 44 of 44 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide7.4 Creating GroupsSwitch to the Groups form by clicking the tab at the bottom of the screen. PathFinderincludes an alternate type of group, Target Groups, which are explained in Chapter 7.8. Theform below will be displayed.Assign the Group a System Name and both In and Out labels. As before, the system nameis only used for navigation within the database and the appropriate label will be displayed,depending whether one is speaking or listening to the Group.Add Group members by clicking the + button. A pop-up list of system ports is displayed.Click on a port or panel from the list and a series of prompts appears for the listen and speaksettings within the Group.There are four listen modes:• Permanent (i.e. cannot be muted)• Normally Made (a key may be assigned to cancel listen)• Normally Broken (a key may be assigned to enable listen)• None (this port can never listen to the Group)There are also four speak modes:• Normally Made (a key may be assigned to stop speaking to the group)• Private, Normally Made (allows private communication with a group member)• Normally Broken (a key may be assigned to enable speaking to the group)• None (this port can never speak to the group).Trilogy Communications LimitedIssue 1Page 45 of 45

7.5 Creating ConferencesPathFinder Version 4.22 User GuideSwitch to the conference form by clicking the tab at the bottom of the screen. Two differentsets of conferences are provided with PathFinder, large and small. By default, the smallconference form is displayed first. Switch between the types using the button in the bottomleft corner.• Small Conferences. A total of 200 conferences, each with 24 members.• Large Conferences. A total of 16 conferences, each with 96 members.The form shown below appears.Assign a suitable name and labels to the Conference. Add members using the + key. Asmembers are added, a view of speak inhibits will gradually appear. By default, all conferencemembers are inhibited from speaking to themselves, thus eliminating howlround. Extrainhibits may be added by clicking on the grid and selecting or deselecting the appropriatesquare. The following example shows a conference with six members, default speak inhibitsplus an additional inhibit which prevents Vision Engineer from speaking to Producer A.Trilogy Communications LimitedIssue 1Page 47 of 47

PathFinder Version 4.22 User Guide7.6 Assigning Panel Keys to Groups and ConferencesFollow the same procedure as for assigning standard intercom keys (see Chapter 6.5.)Other key types that may be used with Groups are:Speak Off, momentary up / momentary downSpeak Off, latching up / momentary downThese keys are appropriate where a Group has been built to provide “normally speaking”privileges to a panel group member.Page 48 of 48 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide7.7 Conference Enhancements7.7.1 Small and large conferencesTwo types of conference are now included within PathFinder. There are:‣ 200 small conferences, each of which may include maximum 24 members‣ 16 large conferences, each of which may include a maximum of 96 members.A button located at the lower left corner of the screen switches the view between large andsmall conferences.7.7.2 Conference OverviewA further button is located in the lower centre of the screen, to select aconference overview. This lists all of the current large and smallconferences and includes the system name, panel labels and the number ofmembers currently included in each conference.The Conference System name and labels may be edited in this view but any further changescan only be made by returning to the “detail” view.Trilogy Communications LimitedIssue 1Page 49 of 49

7.7.3 Conference editing toolsPathFinder Version 4.22 User GuideAdditional conference editing tools may be made visible by the use of two additional buttonslocated at the lower right corner of the screen, in the “detail” view.The first of these is a conference template facility. This works in a similar fashion to thepanel template. A conference may be selected and stored in the conference template, thenpasted into another empty conference allowing minor editing. The second is a set off atspeak inhibit tools which limit the contribution a member makes when added to theconference.Page 50 of 50 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide7.8 Target groupsThis feature allows a commonly used group of destinations to be addressed by a sourcepanel located outside the target group. Unlike groups and conferences, the “source” paneldoes not need to be a member of the target group.Source PanelTarget GroupTarget Groups are accessed from the Groups form, then via abutton in the bottom left corner of the screen, which togglesbetween, conventional and target groups.Target Group members are added in the usual way; the target group is given a system nameand labels, which will appear on the designated source panel “speak” key. The Target Groupmay contain 4-wire members, in which case the “outside” panel can use a listen/speak keyto target the Target Group. When listen is selected, the 4-wire sources will be heardimmediately. This function cannot be used to eavesdrop on other panels.Trilogy Communications LimitedIssue 1Page 51 of 51

PathFinder Version 4.22 User Guide8. IFB'S8.1 IntroductionIFB’s or Interruptible Foldbacks are audio routes which can be broken into or interruptedby a third party, replacing the original audio with the 3rd party panel microphone. Thus anIFB comprises three components:• The IFB Destination – usually a 4-wire port.• The IFB Return Audio. This is the “normal” feed to the IFB Destination.• The IFB Trigger which generates the control signal and interrupting audio.The sketch below shows a typical example of an IFB. In this example the Presenter on theStudio floor is normally listening to the Director on Open Talkback. When the Soundoperator presses his speak key to the Presenter he breaks the audio from the Director’smicrophone and replaces it with his Sound microphone.Director PanelSound PanelReturn AudioIFB TriggerIFB DestinationPresenterThis is an IFB in its simplest form. More complicated IFB’s can be configured using the IFBmenu with the following features available:• Multiple IFB Destinations.• Multiple Return Audio Sources.• Multiple IFB Trigger Sources.• IFB audio can be Cut or Dimmed by a pre-selected level.• IFB Triggers can be prioritised to allow individual Triggers to override other Triggerswithin the IFB group.• Logic Inputs can be programmed as IFB Triggers.For further information on the programming of the more complex IFB facilities please refer toChapter 0.Trilogy Communications LimitedIssue 1Page 53 of 53

PathFinder Version 4.22 User Guide8.2 Programming a Simple IFBThe following example uses:• Director control panel connected to port 1• Sound control panel connected to port 4• Presenter 4-wire circuit connected to port 6.Switch to the IFB form as shown below.Following similar procedures to that used for Groups and Conferences:• Assign a System Name and label to the IFB.• Add the IFB Destination – in this case, Port 6 “Presenter.”• Add the Return Audio Source – in this case, the Director Control Panel.At this point, the form will appear as shown below. There are currently no entries in the IFBtrigger list: there is no method for anyone to speak to the Presenter.Page 54 of 54 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User GuideThe next form shows that two extra keys have been added to the configuration:• A Speak key, on the Sound Panel, targeted at the IFB.• A Speak key, on the Producer Panel, targeted directly at the Presenter.Note that there are now two entries in the IFBTrigger list. The icon in the Connected By fieldshows the type of connection. Note the icondenoting Speak Key adjacent to the Producerentry. This list is generated automatically.Trilogy Communications LimitedIssue 1Page 55 of 55

PathFinder Version 4.22 User GuideCurrently, no Trigger action is set for either of the “potential” triggers. To set a trigger level,right click in the Trigger field and select a level from the pop-up list. The key on theProducer control panel may be converted to an IFB action by assigning a trigger level at thispoint. However, since it was originally targeted directly at the 4-wire port, the key will retainthe label Pres, rather than the unique IFB label Floor.The key on the Sound panel will carry the IFB label Floor.The Sound Engineer now has a priority level 1 key to theStudio Floor Presenter. The Producer retains a simpleSpeak key since no priority level has been set.-------------------------------------------------------------------------------------------------------------------------TIP: It is possible to build the configuration without directly targeting IFB’s at all. Speakkeys may be directly targeted at destination ports, and then modified on the IFB form. Thisconcept can speed the programming process but the keys retain their original labels.-------------------------------------------------------------------------------------------------------------------------For further information on the programming of the more complex IFB facilities please refer toChapter 0.Page 56 of 56 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide9. LOGIC FACILITIES9.1 IntroductionIn many installations of the Commander Intercom system, it is necessary for the system tohave control or be controlled, by third party equipment. This requirement is supported by:• The optional General Purpose Interface card (or GPI card) within the matrix• Local logic inputs and outputs on the standard rack mounting range of control panels.It is important to note that the more complex facilities are only available when the optionalGPI card has been fitted. See the Commander Installation Guide for information oninterfacing the GPI card to third party hardware.9.2 GPI Card Overview (500-10-00)The GPI card occupies one card slot within the matrix and depending on the type ofTalkback Controller card fitted, the system can support a maximum of either 4 or 6 cards.The GPI card is added initially from the Overview Page, as explained in Chapter 6.3. TheLogic form (below) is displayed when the tab at the bottom of the Overview page is selected.Each GPI card has 40 logic inputs and 64 logic outputs. These comprise 28 “real” physicalinputs and 24 “real” physical outputs. The remainder are special software controlled inputsand outputs for more complex logic control and are not directly available on the rearconnector unit. These functions are shown in the table below.Trilogy Communications LimitedIssue 1Page 59 of 59

PathFinder Version 4.22 User GuideThe Logics form allows GPI card inputs and outputs to be configured:• LOGIC INPUTS Allows the logic inputs of fitted GPI cards to be allocated an inhibitlist and/or a logic output.The “polarity” may be configured such that the system expects acontact closure, or a contact opening, to action the inhibit list and/orlogic output.• INHIBIT LISTS Up to 128 inhibit lists are included, each of which may list up to 32source/destinations (crosspoints).When activated by a logic input, the crosspoints listed in theappropriate inhibit list will be broken/inhibited until the logic input isde-activated.• LOGIC OUTPUTS Allows up to 200 system-wide outputs to be configured. These areallocated to GPI card outputs, or to panel outputs.They may then be activated from panel keys.A number of logic outputs on each GPI card perform an “internalloopback” to a logic input, allowing complex logic scenarios to berealised.• LOGIC OUTPUTGROUPSUp to 32 groups of up to 4 logic outputs may be configured. Thisallows a single panel key to action a number of outputssimultaneously.9.3 GPI Card Additional FeaturesAdditional features available on board the GPI card include:A 12 input / output Field Programmable Gate Array3 tone sources programmable as Blip Tones3 audio “wav” filesLogic input and output monitoringAn audio bar-graph PPM using a simple LED display9.3.1 Field Programmable Gate ArrayThe Field Programmable Gate Array (or FPGA) device allows logic inputs 15 – 28 and logicoutputs 11 – 24 of the GPI card to be custom configured by Trilogy to provide more complexlogic functions. A typical example for the use of the FPGA would be to provide interlockingcontrol of switches and there outputs controlling the Transmission and Rehearsal lights in astudio complex.9.3.2 Tone SourcesThe GPI card has three 0dBu tone oscillators available on the first 3 ports of the card.Therefore if the GPI card is fitted in ports 91 – 96 of the matrix, the following ports wouldhave tone available as inputs to the matrix;• Port 91 - 315Hz• Port 92 – 1KHz• Port 93 – 2KHzPage 60 of 60 Issue 1 Trilogy Communications Limited

9.3.3 Tone BlipsPathFinder Version 4.22 User GuideThe tone sources above are also available as Tone Blips. The three Tone Blips are sampledsound files with duration set in the GUI. An example for the use of a Tone Blip could be toalert a destination panel when a particular source panel is calling. This function isprogrammed from the Panel Configuration form of the “sending” panel, as explained below.Select the Tone Blip view of the PanelConfiguration form from the Key View areaof the screen.Now, identify the key that is to incorporate the tone blip. Right click in the small windowcorresponding to that key and choose the required blip source, which in this case is derivedfrom the GPI card fitted in Port 91 – 96.When key 3 on the Studio Director panel is pressed, Edit A (the existing key target) will heara short burst of 1KHz tone at the start of the call.Trilogy Communications LimitedIssue 1Page 61 of 61

9.3.4 Audio WAV FilesPathFinder Version 4.22 User GuideSimilar to the Tone Blips, the GPI card has three sampled wav audio files, with duration setin the GUI. The application of the wav file could be used as an alternative to the Tone Blip.See the previous section for programming information.9.3.5 Logic Input and Output monitoringThe eight green LEDs fitted on the lower front edge of the GPI card indicate the status of thecards logic inputs and outputs. For more information on how to use these LEDs please referto the Commander Installation Guide.9.3.6 Audio PPM.The LED array fitted on the upper front edge of the GPI card is an audio PPM. In conjunctionwith the three rotary switches underneath the array, the user can monitor any input to thematrix available on the TDM bus. Please refer to the Commander Installation Guide for detailon the operation of the rotary switches.9.3.7 Panel LogicLocal logic inputs and outputs are provided on the 500-30 series control panels.

PathFinder Version 4.22 User Guide10. DIMMING10.1 IntroductionComprehensive dimming facilities are provided. This form allows, per destination: -• ASSIGNMENT Displays the currently configured sources to this panel.• MODEDetermines whether the default mirror dimming is to be applied foreach source, or whether no dimming (null dimming) is to be applied.Automatic mirror dimming ensures that when a full duplex route isestablished (i.e. panel A is connected to panel B and vice versa),attenuation of the specific crosspoints is applied.The term mirror refers to the fact that on a source/destination matrixgrid (crosspoint diagram) the A-B and B-A duplex path is a singlecrosspoint mirrored about a diagonal.• GROUPFor instances where mirror dimming does not perform adequately,due to for example acoustic coupling between physically adjacentpanels, a list of source-destinations (crosspoints) may be activatedto dim (attenuate) specific routes in the system.• GROUPAllows the specific source-destination lists to be set-up. Up to 5MEMBERS Dim-Groups may be set-up per panel, each with 32source/destinations.• DIM LEVEL Sets the attenuation applied to the crosspoint routing audio to thispanel when dimming is applied. The dimming level may be set inthe range 0 to -37dBu in 1dB steps.Trilogy Communications LimitedIssue 1Page 63 of 63

10.1.1 Dimming - Additional InformationPathFinder Version 4.22 User GuideMost situations are catered for adequately by mirror dimming. Generally it is advised that allpanels are given a dim level of somewhere between -9dB and -25dB - this is a trade offbetween howl-round prevention and level reduction and must be determined empirically.Note that PathFinder will, by default, set a dim level of –25dB for all ports.Mirror dimming caters for the normal scenario where panel A is connected to panel B, andvice versa. This will cause an immediate feedback loop and howl-round. The software canautomatically detect this situation and apply attenuation to the offending crosspoints.The most complex aspect of dimming is the use of special dim groups. These are providedto cater for the scenario where no obvious feedback path exists - and which the softwarecannot therefore predict.A typical example might be two panels in close physical proximity when there are two furtherremote panels, each in completely different location both to themselves and the two closecoupledpanels. Feedback can occur in this typical scenario, depicted below with the tworemote panels as R1 and R2 and the two close-coupled panels as CC1 and CC2.• Remote panel R1 is speaking to panel CC1• Close-coupled panel CC2 is speaking to R2• R2 is speaking to R1Audio from R1 appears at the loudspeaker of CC1, and will be picked up by the microphoneof panel CC2. Since CC2 is speaking to R2, the audio therefore appears at the loudspeakerof panel R2 to be picked up by R2’s microphone. Since R2 is speaking R1, the acousticloop is completed and howl-round occurs.Panel CC1Panel R1, speaking to CC1FEEDBACK!Panel CC2 speaking to R2.Due to acoustic coupling to CC1, Audiofrom CC1 is also picked up by this paneland received by R2.Panel R2, speaking to R1.This panel received audio directfrom CC2, plus coupled audiofrom CC1, which is from R1,which is from this panel.The software cannot predict this, and the exact solution depends on the operationalrequirements of the installation.In principle, the solution is to use (for example) the action of panel R2 speaking to R1 toautomatically trigger dimming of the route from R1 to CC1.This is implemented by accessing the dimming form for panel R1. R2 will be shown as apotential source to R1; in the dim group column enter group 1.Edit group 1 and add the crosspoint with R1 as the source and CC1 as the destination.When R2 speaks to R1, the dim factor set-up for panel CC1 will attenuate the route from R1to CC1.Page 64 of 64 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide14. IFB’S - ADVANCED14.1 IntroductionIFB theory and Programming a simple IFB are explained in Chapter 0. More advancedprogramming features available are:• Multiple IFB Destinations.• Multiple Return Audio Sources.• Multiple IFB Trigger Sources.• IFB audio can be Cut or Dimmed by a pre-selected level.• IFB Triggers can be prioritised to allow individual Triggers to override other Triggerswithin the IFB group.• Logic Inputs can be programmed as IFB Triggers.14.2 Multiple IFB DestinationsIt is conceivable to have up to 4 IFB destinations configured in an IFB. As IFB destinationsare added, the IFB trigger source list will automatically update to show all the availablesources to the IFB destinations. Using the IFB trigger source list “Connected by” entry, it ispossible to see how each available source crosspoint is controlled, whether it be a panelspeak key or a group key etc.The simple example from Chapter 8.2 is shown again below, with an additional IFBdestination (Announcer on Port 18).The addition of Announcer as an IFB destination hascaused Production Assistant to appear on the IFBtrigger list. By default, there is no IFB trigger action.Trilogy Communications LimitedIssue 1Page 79 of 79

PathFinder Version 4.22 User GuideBy default, members in the IFB Trigger Source list are set to none, therefore when theytrigger their crosspoint to the IFB destination the audio will mix with the IFB return audio. Toset the IFB trigger to break the return audio, the Trigger Action level needs to be set to alevel of 1, 2 or 3.14.3 Multiple Return Audio SourcesIt is possible to have up to 16 Return Audio sources configured to an IFB. Each return audiocrosspoint is normally made to the IFB destination. All the return audio crosspoints arebroken when a level 1 – 3 trigger source activates the IFB.14.4 Multiple IFB Trigger SourcesOnce the IFB destinations have been selected, the Trigger Action needs to be set in the IFBTrigger Source list. As explained above, setting the IFB Trigger Action to none causes theTrigger Source audio to mix with the Return audio. To cause the Trigger source audio tointerrupt the return audio, the Trigger Action needs to be set to a priority level.The Trigger Action priorities are such that priority Level 1 will override a priority Level 2, etc.Therefore any priority 1 panel speaking to the IFB destination will not only interrupt thereturn audio feed but also interrupt trigger sources speaking with a priority of 2 or 3. A panelset to priority none will not be interrupted.To confirm how the IFB will actually work, click the appropriate row of the Breaks column.This will display, using a symbol, all the trigger sources that will be overridden by theselected trigger source.As IFB destinations are added, the list of potential sources to the IFB destinationautomatically updates to include these sources. This allows priorities to be assigned asrequired.Priorities are such that priority 1 is higher than priority 2, etc. Therefore any priority 1 panelspeaking to the IFB will not only interrupt the return audio feed, but also sources of priority 2or 3.The special none category is provided to ensure that a source with this priority will not beinterrupted by other sources speaking to the IFB destination(s). The audio contribution fromsuch none sources thus mixes at all times with the return audio feeds.Since the Commander system allows users to locally re-assign their keys to targets, whichmay be an IFB destination(s), it can be useful to specifically add sources to the list althoughthey do not currently have a key to speak to the IFB.This may be done via the IFB+ button (and conversely removed using the IFB- button). Apriority may then be pre-assigned.In addition, the default priority may be set as required. This ensures that as new sourcestarget the IFB destination(s), - whether by the user re-assigning keys, or from withinPathFinder - they take on a priority appropriate to the installation.To determine how the IFB will actually work, the “breaks” column on the form may be used.Clicking an appropriate row of the “breaks” column will cause all sources that would beinterrupted in addition to the return audio sources to be displayed with a symbol:Page 80 of 80 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User GuideIn this example the VTR 2 breaks cell has been clicked. VTR 2 is a level 2 trigger, so willbreak only level 3 sources; this is shown by the arrow symbol in the cells corresponding toFloor Manager and VTR 1.This is summarised in the table belowPriorityNoneLevel 1Level 2Level 3ActionDoes not break return Audio feed(s), nor any other sources that connect to theIFB destinationBreaks the return audio feed(s) and Level 2 and 3 trigger sourcesBreaks the return audio feed(s) and Level 3 trigger sourcesBreaks the return audio feed(s) but no other trigger sources14.5 IFB Return Audio DimmingBy default the trigger source will cut the IFB return audio and cut any trigger source audioset at lower priority. If the radio button at the top of the screen is set to Dim, the return audioand overridden trigger source audio will now be dimmed by the level set next to the dimradio button.14.6 Complex IFBThe following example shows a more complex IFB, with multiple destinations, return sourcesand triggers.

PathFinder Version 4.22 User Guide15. LOGIC FACILITIES – ADVANCED15.1 Programming System Logics: Inputs15.1.1 OverviewSystem logic inputs are only available when the matrix has a GPI card installed. Please referto Chapter 6.3 for information on adding a GPI card to the PathFinder GUI.From Version 4.15 onwards, the logic input form has been extended. The “AdditionalFunctions” field has been split to show logic o/p and 4-wire port as separate fields. Thisgives improved flexibility in programming, since a logic input can now be used to target alogic output and set up a 4-wire call. An extra text field has also been added (labelledcomments) which should be used to explain the functionality of the logic programming.The form also reports any logic inputs assigned to IFB’s (see Chapter 15.1.5).15.1.2 Logic Inputs triggering Crosspoint ListsA logic input triggering a crosspoint list is used as a means of remotely controllingcrosspoints within the matrix. A typical example could be a logic input from an On Air switchto prevent audio being routed to the studio floor talkback loudspeaker when the studio istransmitting. Another example could be a simple panel using switches wired to the GPI cardlogic inputs to route audio from its panel microphone to the required destinations within thematrix.15.1.2.1 Programming logic Inputs triggering Crosspoint ListsProgramming a logic input to trigger an inhibit list is a two part operation.1.

Onremoving the logic input, the tally remains flashing until one of the panels in the systemanswers the call, thus clearing down the tallies on all panels receiving the call.The 4-wire call persistence mode is set from the Options | Settings | Operation menu. Tickthe 4 wire persistence check box to set 4-wire call persistence mode.Page 88 of 88 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide15.1.4.2 Programming the 4-wire call panel alertThis feature is designed to provide an additional audible indication of an incoming 4-wire callto a panel.To program, select the Panel Config tab and use the navigate keys to choose the panel.Select the Miscellaneous view using the radio buttons. To assign a panel Alert source, rightclick in the window and select from the pop-up source list as shown below.This source can be derived from a Misc. I/O logic card (if fitted) or from an external audiogenerator connected to a matrix input.The panel alert is only audible whilst the logic input generating the 4-wire call is activated.The operation is similar to that of a non-persistent 4-wire tally.15.1.4.3 Logic inputs triggering IFBsThe Logic Input, as an IFB trigger is a useful enhancement to the IFB function. The featureis only available if the matrix is fitted with a 500-10 Misc. I/O card. The reason for targeting aLogic input to an IFB Trigger is to enable panels to be barred from operating IFB circuitswhen the system is operating in a particular mode, for example “On Air”.As an example, if the Logic Input assigned to an IFB trigger is set to, say priority 2, and apanel in the IFB trigger group set to a lower priority, i.e. priority 3. When the Logic input ismade, the panel at priority 3 will no longer break the IFB standing feed and will be barredfrom speaking to the IFB destination.Trilogy Communications LimitedIssue 1Page 89 of 89

Reference source not found. for an explanation of programmingsystem logic outputs.15.4.7 Logics – Additional Information15.4.7.1 Normally Open and Normally Closed TerminologyThe nomenclature “Normally Open” and “Normally Closed” is derived by analogy to relaycontacts.If a logic output is normally open, the output “contact” is off. To activate the output, the keydriving the logic output must be pressed on.If a logic output is normally closed, the output “contact” is on. To deactivate the output, thekey driving the logic output must be pressed on.If a logic input is normally open, it behaves as if a “contact” driving the input has not beenclosed – the inhibit list and/or other function associated with the input is not activated bydefault. The physical input must be driven on to implement the associated function.If a logic input is normally closed, it behaves as if a “contact” driving the input has beenclosed – the inhibit list and/or other function associated with the input is activated by default.The physical input must be driven on to undo the associated function.15.4.7.2 Special use of Logic Inputs and Outputs on GPIO CardsEach GPIO card has 40 logic inputs and 64 logic outputs.

PathFinder Version 4.22 User Guide17. TELEPHONES17.1 IntroductionPathFinder provides comprehensive telephone support, allowing auto-hunting of a number ofphone lines from a single key for outgoing calls, and auto-routing of incoming calls to aspecific panel, or to a pre-configured set of panels. System wide Auto-dial numbers may beentered for speed dialling from panels. Additional hardware must be purchased andinstalled, as explained in the Installation Guide. Full facilities are only available if the TelosONE hybrid is used. This connects to the Commander matrix via the Trilogy 500-19 seriesTelephone Interface Unit. For correct operation, the port must be configured as a TelephonePort on the Overview (see below) and connected using 4 pair cable for audio and datatransfer.17.2 Configuring DTMF PortsFrom the System Overview, configure the port as Telephone Port and assign System Nameand labels.Now switch to the Telephone form, using the tab at the bottom of the screen.Trilogy Communications LimitedIssue 1Page 99 of 99

17.3 Building A Telephone GroupPathFinder Version 4.22 User GuideAssign a System Name and label to the DTMF Group as normal. The label will subsequentlyappear on panel keys assigned to the DTMF Group. Normally only a single DTMF Portwould exist in each DTMF Group although the addition of extra DTMF ports allows autohuntingof lines for outgoing calls.Panels who intend to contribute or participate in the Telephone Group must be added to theDefault Destinations list in the centre of the screen. The right hand column allows Direct Dialdestinations to be defined. The two-digit code allows an incoming caller to contact a paneldirectly. This may be compared to DDI operation on a conventional switchboard system.An example form is shown below.Four panels can now participate in the Telephone Group. When suitable keys have beenadded to the panels, they will be able to make outgoing and receive incoming calls. Theabove form also allows audible ringing to be turned on or off, on a panel by panel basis,such that busy operational areas are not unduly disturbed. The same facility is providedseparately for DDI style calls in the right hand table.Page 100 of 100 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide17.4 Assigning Telephone Keys to Control PanelsMost operational requirements may be met by using the two DTMF keys shown below.DTMF Combined key provides hands free conversation. The speakmode from the panel is permanently active.DTMF Seperate key provides “private” conversation. The speakmode from the panel is only activated when the key is pressed down.As part of the Telephone Group in the previous example, a DTMF combined key has beenadded to the Supervisor Panel as shown below.Trilogy Communications LimitedIssue 1Page 101 of 101

17.5 Telephone Group OperationPathFinder Version 4.22 User GuideOperationally, the DTMF system is straightforward.17.5.1 Incoming Calls• When an incoming call is answered by the Telephone Hybrid, all panels in theappropriate group will ring (visually and audibly if configured). The visual tally is flashingof the red and yellow tallies simultaneously.• Any panel in the group may answer the call by flicking their telephone key brieflyupwards.• The panel’s key will, in its default “rest” state, take on the label for the phone group towhich it is assigned.• Once an incoming call is received, the label will change to that of the specific line that isringing.• That panel then “owns” the call and is either in “open” conversation with the caller(combined key, as shown above) or “private” conversation (separate key, as explained inthe preceding section).17.5.2 Outgoing Calls• Pressing a free phone key upwards initiates an outgoing call. The software searches fora free line in the telephone group, and “seizes” it for the exclusive use of the panel. Thekey’s label will change to that of the appropriate port.• The dial pad may be used to dial the required number.• AutoDial numbers may be sent by using the Settings AutoDial prefix (for example *)followed by the 2 digit AutoDial code.17.5.3 Placing Calls on Hold and Transferring Calls.• The current owner may place a call on hold, by a second brief up-press.• Once on hold, a call may be picked up at a new location, by any other member of thattelephone group, by a further key up-press at the new location.17.5.4 Clearing a Call• Only the current owner may drop the call. This is effected by pressing the ‘phone key up,then down, then back to centre in a single movement.17.5.5 Telephone Key TalliesOnly two panel tally states are provided with Telephone Keys:• Flashing Red and Yellow :Incoming call, or call is on-hold• Solid Red and Yellow: Panel has ownership of call and is speaking17.5.6 Clearing a CallWhether incoming or outgoing, a call is cleared by a second upward press of the phone key.Within 2 seconds, the key must then be pressed downwards.Page 102 of 102 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide18. IFB ASSIGNMENTThis function of PathFinder allows rapid re-assignment of IFB Return Audio Sources to apre-defined IFB, from any panel in the system.Used in conjunction with the IFB Assignment Form (see PathFinder User Guide for a fullexplanation of this feature), two new key types are added to the Panel Configuration Page.IFB Return Audio KeyIFB Destination KeyIf PathFinder has recently been installed then these key types will not be available From theOptions pull-down menu, pick the Settings optionAdd the two IFB key types. The left pane shows all of the key type: the right pane showsthose which will be displayed on-screen.When the two keys have been added, pick OK. PathFinder must be re-started before theseadditions take effect: Follow the on-screen prompts.The new key types may be used on an existing panel or a new dedicated panel: both optionsare valid and this is an operational decision.The normal operation of using these two keys is to rapidly assign IFB Return Audio Sourcesto use with these destinations.The example below shows a 24 key panel with the top 12 keys used as IFB Destination keysand the bottom 12 keys set for use with twelve possible IFB Return Audio Sources.The Labels below the IFB Destination keys will take their labels from the IFB page, and thelabel above the Return Audio Source key will take the five-character label from the portlabelling on the configuration overview. These are the only steps needed to configure keyson the panel - the other steps needed are to do with the IFB page in PathFinder andoperation of the port itself.Trilogy Communications LimitedIssue 1Page 103 of 103

PathFinder Version 4.22 User GuideIn the following example we are going to take a typical IFB for a sports programme. The IFBdestination is Programme Sound with the trigger sources being set as standard intercompositions in the studio. The IFB Return Audio Sources will be left un-assigned, as this will bedone from the panel. You can add a Return Audio Source at this stage but the paneloperation acts in a different way, which will be explained later.To use the example above, here is an updated panel with IFB destination and Return AudioSource keys. It shows the name of the IFB SPORT next to the IFB destination key and theReturn Audio Sources are taken from two ports Stadium North and Stadium South with theircorresponding mnemonics Sta_N and Sta_S displayed next to the keys.18.1 Panel OperationOnce you have re-started PathFinder with the new configuration, looking at the exampleabove the IFB Assignment panel will show in it’s quiescent state the labels for the IFB (IFBdestination keys) and the labels for the Return Audio Sources (keys). The following Chapterexplains how to assign the Return Audio Source (stadium North and Stadium South) to ourSports IFB.First, select the Destination by pressing the key down. This key is then software latched andthe yellow tally for this key will flash. Next select the Return Audio Source by pressing theStadium North key downwards, it’s red LED will flash to show it has been selected.Complete the operation by pressing the IFB Destination key down again to un-latch it. Youwill notice that the label has changed from SPORTS to Sta_N to show stadium north hasbeen assigned to Sport Programme Sound. This is to show at a glance which Return AudioSource is routed.It is possible to assign up to four Return Audio Sources to a given IFB destination, and this isindicated in a different way on our example panel. Selecting IFB Sport again will show thatStadium North is routed to it, we can de-select this by pressing the key down. We can addanother Return Audio to a destination by pressing the Stadium South key; the red tally lightsPage 104 of 104 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guidewill flash against this key. When this is completed pressing the IFB destination key again willcomplete the process. Now the Sta_N label against this destination will flash. It is indicatingthe first Return Audio Source is Stadium North which is displayed on the panel and this isflashing to indicating that one more Return Audio Source is selected to this destination.Since other panels in the system could have IFB Destination and Return Audio Source keys,there is a feature to protect re-assignment of given IFB’s.This will effectively freeze a given IFB. Select the appropriate IFB destination and press thekey up. Protection of this IFB will then be shown as the red and yellow tallies flashingrepeatedly. Selecting this key again will remove protection, and make this IFB available to allother assignment panels.The last operational feature of IFB Assignment is assigning a Return Audio Source to anumber of IFB destinations.Press the Return Audio Source key down and it will become software latched with the redtally LED flashing. If this is already routed to IFB destinations their corresponding yellowtallies will illuminate. Selecting these IFB destinations will de-assign them or selecting otherIFB destinations will assign them to receive this Return Audio Source. By again pressing theReturn Audio Source key will complete the operation is completed`. The panel display forthese IFB destinations will then update to the label of the first Return Audio Source.Trilogy Communications LimitedIssue 1Page 105 of 105

PathFinder Version 4.22 User Guide19. SYSTEM NETWORKING19.1 Network Configuration OverviewThere are a number of extra steps required in order to configure a set of matrices to functionas an interconnected network or LAN. It should be noted that no database tables areexchanged between matrices. Each matrix runs an independent configuration and must beprogrammed with both its own local details and any relevant details on the other matrices.This philosophy allows the network supervisor much greater control over the configuration ofnetwork routes. Each network circuit must be independently configured at each end of theroute.Networking functionality is provided as an option within PathFinder and will only be visiblewhen this option has been unlocked with a new software key. Please contact Trilogy formore information.19.2 Hardware ConfigurationThis is explained in the Commander Installation Guide. To summarise:• The E1 Network Cards must be supplied and fitted in pairs. Therefore, a simple twosystem LAN will require two E1 cards.• Each pair of E1 cards provides six 4-wire circuits plus their associated panel data.• Increasing the number of E1 cards will provide extra capacity. In the example above,if a total of four E1 cards is fitted (two in each matrix), capacity is doubled to givetwelve available circuits at any time.• A three matrix LAN implies the arbitrary existence of a central hub with two satellitematrices. A total of four E1 cards are now required: two in the hub and one in eachsatellite.• Communication from satellite to satellite goes via the hub matrix and utilises onecircuit from the six available on each E1 link. This is referred to as system hopping.• Other hardware connection methods are possible, including “serial networking”where the data and audio are transported independently.Trilogy Communications LimitedIssue 1Page 107 of 107

19.3 Software Configuration OverviewPathFinder Version 4.22 User GuideEach matrix has its own local PathfFinder database. Just as before, this carries all of thedata relating to inter-panel communication, 4 wire circuits, local groups, conferences etc.This is defined in exactly the same way as previous PathFinder versions. A prior workingknowledge of the basic steps of PathFinder programming is assumed. Before starting anynetwork related configuration, you should be familiar with:• System Overview• Panel Configuration: defining and targeting keys.There are a number of extra database tables solely related to networking facilities. Thesedefine the following: -• System Number• Network Handles• Remote TargetsThe software configuration is a six-stage process.• Plan the LAN by choosing appropriate system names and numbers. See section19.4.• Complete the System Overview, adding information relevant to the physical layout ofthe matrix port allocation, this includes panel types, 4 wire ports, telephone ports,logic cards and network ports where appropriate. See section 19.5• Add local matrix functionality. See section 19.6• Define local Network Handles. See section 19.7• Define Remote System Targets. See section 19.8• Continue programming panel key layouts by adding keys, which target other (remote)systems. See section 19.9.The system can be configured with three different network port types. These are:• Network Port Free Pool.As the name implies, these network ports are used on a “first available” basis. Ifcommunication between two systems is required, the first available free port will beallocated for the duration of that conversation.• Network Port Dedicated.The Dedicated network port allows a panel on System A not to be restricted by “firstavailable” basis of Free Pool networking and be guaranteed access to System B viathe E1 link.• Network Port 4 wire.The 4-wire Network port behaves in similar way to a copper wire connection from a4-wire port on System A to a 4-wire port on System B.These subjects are discussed in the following sections.Page 108 of 108 Issue 1 Trilogy Communications Limited

When prompted, enter the system number “1”.The system name and system number should now be correctly displayed on the overviewstatus line adjacent to the text “System Overview”. Now continue by defining the systemhardware on the System Overview page. In this simple example, six panels and a singlenetwork card are shown on the first twelve ports of the matrix. Define the port type asNetwork – Free Pool: the other Network port type options are explained in section 2.8. TheFree Pool example is shown below.StatusLineRemember to save the PathFinder database at regular intervals.Trilogy Communications LimitedIssue 1Page 111 of 111

19.6 Local FunctionalityPathFinder Version 4.22 User GuideNow add as much local functionality as possible. This includes:• Inter panel communication• 4 Wire Circuits• Groups, conferences, IFBs• Logic functionsWhile defining and adding panel keys, make sure that sufficient key positions remain to addnetwork keys at a later stage. For the purpose of this example, only local inter-panel keysare considered at present. The key layout of panel 2 is shown below.Page 112 of 112 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide19.7 Network HandlesOn each matrix database, decide which elements are allowed to participate in networkactivity. At present, these may be• Ports (i.e. Panel or 4-wire ports)• Target Groups (explained in section 19.13)Each element is assigned a unique identification tag called a Network Handle. This isnumeric and may be non-sequential. It is unique within each database but may be repeatedon other matrices within the LAN. Our simple set-up now assumes that only Panel 2, Panel 4and Panel 6 take part in any network activity. Therefore, only these ports need to haveNetwork Handles defined. For simplicity, the example shows Network Handles H2, H4 andH6 applied to these ports. Simply click in the correct row of the Net Assignment column,then type in the numeric value of the Network Handle. As the cursor is moved to anotherfield the icon and graphic shown below will appear. Alternatively, follow the instructions onthe status line to use the F2 key, which automatically assigns the next numerically freeNetwork Handle.Port Type System Name In Label Out Label Network?

PathFinder Version 4.22 User Guide19.8 Defining Remote System TargetsFor each matrix, define the Remote Targets, which will be addressed. This requires priorknowledge of the System Numbers and Network Handles, which have been defined on theother systemsRemote System Targets are defined on an alternative view of the System Overview Page.Select the Remote Target button in the bottom right corner of the screen and the view shownbelow will appear.The Remote Targets may be allocated sequentially or in “blocks” which allows for morelogical programming.Remote Targetview selectedFollow the steps below to define Remote System Target 1• Click (or double-click) in theSystem column, at row 1. A pop-upwill appear showing the availableSystem Numbers, which weredefined in section 2.2.• Select the required Remote System.• Hit the tab key to move to the next field ‘Net Handle’.• In the Net Handle column, type a numeric value, This number corresponds to the NetHandle number applied in the System Overview of the remote studio’s database.• Finally, enter the name and appropriate labels for this remote target. The 5 characterlisten/speak labels will be the neumonic which will appear on the panel key as shown insection 19.9.Page 114 of 114 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User GuideIn the example below, we are programming the database for Studio 1. Here, we havedefined Remote System Target 1 as the Sound panel in Studio 3. From our prior knowledgewe know that this panel carries Net Handle H2 in the Studio 3 database. A series of RemoteSystem Targets in other matrices is also shown.Trilogy Communications LimitedIssue 1Page 115 of 115

PathFinder Version 4.22 User Guide19.9 Programming Panel KeysContinue programming panel key layouts by adding keys that target other (remote) systems.Select the Panel Configuration view and select the panel to be programmed for remotetargets. Choose a key type and apply it to the push-button on screen. Now right click in theadjacent display window and a pop-up window will appear. In addition to the usual localtargets (i.e. ports, groups, conferences etc.) a section of Remote System Targets is shown.The example shown below shows key 5 targeted at Remote System Target 1, which wehave previously defined as Studio 3 Sound.For complete 2-way communication, a corresponding entry should be made in the Studio 3configuration, on the Sound control panel. This will allow the other operator to reply andensure that tallies across the two matrices are displayed correctly.Page 116 of 116 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide19.10 Network Ports – DedicatedOn the overview page, there are three different network port types available on the pop-upmenu. These are:• Network Port 4 wire• Network Port Free Pool• Network Port DedicatedIn our initial simple configuration (section 2.3) we assigned the E1 Network card as a groupof six Free Pool ports. As the name implies, these ports are used on a “first available” basis.If communication between two systems is required, the first available free port will beallocated for the duration of that conversation. Therefore, with a single network card in eachsystem, up to six independent conversations between systems can take placesimultaneously. If a seventh route is requested, the request will be denied. The “speak” keyon this panel will display a flashing red tally, which indicates request cannot be achieved.Operationally this may be unacceptable. There may one or more key persons in theorganisation (e.g. Transmission Director) who must be permitted to speak at all times. Thiscan be accomplished by changing one or more of the Free Pool network ports to Dedicatednetwork port status.19.11 Selecting a key personTo set up a Dedicated Network port, first choose a Free Pool port and change it’s status to aDedicated port.It is beyond the scope of this document to fully explain this process but please note thefollowing;• Initially, the dedicated port need only be assigned at one end of a link• The dedicated port should be assigned to the listening system with a remote target set tothe “key person”.The example below illustrates this. Our configuration for Studio 1 has Remote SystemTargets assigned as shown in section 2.6 on page 13. This shows that Remote SystemTarget 6 corresponds to the MCR manager located on the Central Hub matrix. We will nowdefine the MCR manager as a key person.In the System Overview page, select the row corresponding to the last available Free Poolnetwork port. In our example this is port 12. Right click in the Port type column and chooseNetwork Port – Dedicated. The icon will change as shown below.Trilogy Communications LimitedIssue 1Page 117 of 117

PathFinder Version 4.22 User GuideEnter a system name to serve as a reminder. Since the port will not be directly addressed,there is no requirement to enter labels. These two columns may be left blank. Move thecursor across to the column labelled Net Assignment. Following the instructions on thestatus line, use the F2 key to display the available Remote System Targets. For thisexample, select 6 which corresponds to the MCR manager. This now ensures that:• Any communication from MCR manager to Studio 1 will use the dedicated port• No other inter-studio traffic may use this port• The number of free pool ports is now reduced to 5.See below for the final stage of the configuration.Page 118 of 118 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide19.12 Assigning a Dedicated Port in the reverse directionThe configuration explained above guarantees that the MCR Manager will always be able tospeak to operators in Studio 1. To ensure that the reverse direction any replies from Studio 1operators are heard by the MCR Manager, the Network Port type in the Central Hubconfiguration must also be edited. As shown below, the final Free Pool network port isconverted in the Central Hub configuration to a Dedicated port, similar to the previousexample. However, the entry in the Net Assignment column is set to a local (i.e. CentralHub) Net Handle value, corresponding to the MCR Manager. This ensures that:• Any communication from Studio 1 operators to the MCR Manager in the Central Hubuses the dedicated line.• Only five Free Pool routes from Studio 1 to the Central Hub are now available.Follow the instructions on the Overview Page status line and see the completed examplebelow.This concept may be expanded to cover LAN systems comprising three or more matricesalthough there are some limitations. Please contact Trilogy Broadcast for more information.Trilogy Communications LimitedIssue 1Page 119 of 119

PathFinder Version 4.22 User Guide19.13 Target GroupsThe previous examples of network communication in this guide are concerned with SystemA communicating with a single port in System B. If there is a requirement for a panel insystem A wishing to communicate with two or more panels or 4 wires in system B, a TargetGroup needs to be configured across the Network.To program a Target Group that can be accessed across the network the following stepsshould be followed. The example below shows how panels in System A can access a TargetGroup in system B.• First make sure each of the ports to be assign as a Target Group in the remote system(system B) have an individual network handle assigned in the System Overview asdescribed previously in section 2.5.• Select the ‘Group’ tab, then the ‘TargetGps’ radio button and add the relevant ports tothe Target Group using the + icon to add new members.Select the correct view inthe lower right corner of thescreen.• Next, select the ‘Overview’ radio button. The last column in the Target Group overviewtable relates to the Network Handle number to be assigned to the Target Group. Thisnumber has to be unique value and be different from the Net Handle numbers assignedin the system overview.• In the Pathfinder GUI each system is allowed a total of 255 Network Handles. If thesystem is, for example a 192 port system, the Net Handles allocated to Target Groupscould be numbered from 193 onwards. This will allow the flexibility of any port in the 192port system to be networked in the future.Type 193 thenpress the tick(check).• The penultimate step is in the System A configuration add the Target Group handlenumber in the System Overview/Remote Targets form.• Finally, in the System A configuration, select the Panel Config page and target therelevant panel keys to the Remote System Target that is assigned to the Target Group.Page 120 of 120 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide19.14 4-wire Network PortsThe third variant of network port is the 4-wire Network port. The 4-wire Network port behavesin a similar way to a copper wire connection from a 4-wire port on System A to a 4-wire porton System B. A typical application would be to connect a Conference in System A to aConference in System B.It is important to note, when assigning a port on the E1 network card as a 4-wire Networkport, the remote system E1 network card must also assign the corresponding port as a 4-wire port. So as an example, the E1 card in system A is fitted in slot 91 – 96 and the fourthport on the card is assigned as a 4-wire port (port 94). Then at remote system end (SystemB) if the E1 card is fitted in ports 31-36, the 4-wire port must be assigned to port 34.19.15 QRS keyThe Quick Response Key (QRS) functionality is provided on panels that have speak keysacross a network link. As always, it is good practice to include a QRS key on control panelsshould space permit. However, it should be noted that to allow complete QRS operationacross a network link, all panels will require both handles and corresponding RemoteSystem Targets to be correctly defined on all systems.Trilogy Communications LimitedIssue 1Page 121 of 121

PathFinder Version 4.22 User Guide20.6 OperationA number of features may be selected or deselected by check box.20.6.1 Rotary encodes varies listen gain from panels.When this is checked, selecting a 4-wire listen key on a panel activates the panel REN forten seconds allowing the operator to adjust his cross-point level for that incoming 4-wire.20.6.2 4 Wire Call Persistence4 Wire calling can work in two different modes, persistent and non-persistent. In nonpersistentmode, the 4-wire call signal displayed on the panel matches the duration of thelogic-input closure, plus the time set for tally hold up. For example if a logic input is appliedfor 5 seconds and the tally hold up is set to 2000 (2 seconds) then the 4 wire call durationdisplayed on the panel LED will be 7 seconds.In persistent mode, the logic input triggering the 4-wire call is latched within PathFinder andthe corresponding tally is also latched until the call is answered.20.6.3 Twinklers ActiveTurns on twinklers at all times.Trilogy Communications LimitedIssue 1Page 127 of 127

20.6.4 Show Twinklers when keys activePathFinder Version 4.22 User GuideTwinklers are signal present indicators, displayed on panels using the yellow tally LEDadjacent to keys. The mode of operation can be changed with the two checkboxes accordingto the following table.Status of yellow“twinkler”No signal present,not listeningSignal present, notlisteningNo signal present,listeningSignal present,listeningTwinklers active checkbox NO NO YES YESShow twinklers when keysactive checkboxNO YES NO YESOFF OFF OFF OFFOFF OFF MED MEDON ON ON ONON ON ON SLOW20.6.5 Speak / Listen keys display Speak labelEntries on the Overview form allow two labels to be assigned to each port. When alisten/speak key is targeted to a port, by default the panel will display the “listen” label. If thecheckbox is ticked, then the “speak” label is displayed instead.20.6.6 Re-set PC adapter card on message timeoutThis should normally be left checked and only disabled for faultfinding purposes.20.6.7 Tally Hold up and Tally Hold up DurationIf enabled, this sets the time in milliseconds (mS) that the tally is left on, after the caller hasreleased his key. Available range is 0 to 30000mS (0 – 30 seconds).20.6.8 QRS Timeout and QRS Timeout DurationIf enabled, this sets the time in mS that calls appearing on a QRS key remain displayed, toallow a return call. Available range is 0 to 30000mS (0 – 30 seconds).20.6.9 Tone Blip DurationThis sets the duration of tone blips generated by a GPI card (500-10-00) if fitted. The defaultis 500 (½ second) with an available range of 0 to 5000mS (0 – 5 seconds).20.6.10 Wave Blip DurationThis sets the duration of wave file blips generated by a GPI card (500-10-00) if fitted. Thedefault is 2000 (2 seconds) with an available range of 0 to 5000mS (0 – 5 seconds).20.6.11 Panel Call – Group Tally before QRSThis option changes the order of one of the search algorithms used in PathFinder. If Panelcalls Panel B and there is no dedicated key on Panel B to display the tally, then the searchorder is:1. A QRS key2. A suitable Group key (i.e. both panels are Group members).If the box is checked, this order is reversed. Operationally, this means that the return callfrom Panel B to Panel A will go to all members of the group who are currently listening. Thismay be operationally confusing.Page 128 of 128 Issue 1 Trilogy Communications Limited

20.7 On-LinePathFinder Version 4.22 User GuideThese options only apply during “live” connection to the system, when the “Rapide” optionhas been purchased and installed.20.7.1 Auto Flash SaveWhen this box is checked the system will automatically save the currently edited PathFinderConfiguration to a designated Flash RAM bank.

PathFinder Version 4.22 User Guide21. UPGRADING FROM AN EARLIER VERSION OF PATHFOINDER21.1 IntroductionThere are some important factors to consider when upgrading from an earlier version ofPathFinder.‣ The data table format is (usually) altered with each numeric upgrade step (e.g. from 4.14to 4.15). The conversion utility is a one way process so it is sensible to carry out acareful back up prior to the upgrade.‣ The User Settings will revert to the default values during the upgrade. Make some notesof the settings before starting the upgrade process.‣ Version 4.15 installs to an independent directory location, which allows the previousversion to remain on the PC. Therefore, when upgrading to 4.15, it is not essential tocarry out Step 3 below.‣ Are the previous PathFinder installation disks available? This affects the sequencefollowed during the upgrade. See Chapter 21.2.1 if the previous disk set is available andChapter 21.2.2 if the previous disk set is not available.21.2 Reverting to a previous versionFor whatever reason, it may be necessary to revert to the earlier version of PathFinder.Before commencing, check the availability and integrity of the previous set of installationdisks. If the disks are not available, an alternative plan is suggested in Chapter 21.2.2.21.2.1 Previous disk set is availableThe steps are outlined below:Step 1 Make a back up copy of all (required) configurations using Windows Explorerand standard Windows file handling “copy” and “paste” commands. Each configurationconsists of a large number of individual files with a common prefix. Make certain that all ofthe relevant files are copied.Step 2. Start the existing version of PathFinder and view the “Settings” dialogue.Some settings are only User Preferences and will not affect the basic program operation.Two important ones are the Adapter Card address and the number of ports of the matrix.Take careful note of these.Step 3 Close PathFinder, then from Windows | Settings | Control Panel | AddRemove Programs, highlight the current version of PathFinder and follow the prompts toremove the program.Step 4. If you are prompted to re-start Windows, then do so.Step 5 Follow the set-up routine with the new version of PathFinder, inserting diskswhen prompted. The set-up routine creates a folder with three icons, which can be copied tomenus or desktop as preferred. These are covered in Chapter 3.3.The basic installation is now complete but needs configuring before use. See Chapter 3.7.Trilogy Communications LimitedIssue 1Page 131 of 131

21.2.2 Previous disk set is not availablePathFinder Version 4.22 User GuideThe method suggested below is not advisable for repeated version upgrades. Also, sinceVersion 4.15 is installed to a separate directory structure, it is not actually necessary to uninstallthe previous version.For the purpose of this document we will assume the upgrade is from version 4.14 to version4.15. Follow steps 1 and 2 as above but version 4.14 should not be removed. Instead,Step 3 Using Windows Explorer, re-name the Pathfinder and Borland programdirectories as shown below.Rename as Borland4_14Rename as Trilogy4_14If there is a requirement to revert to the “old” version, then use the same process to renamethe “new” version as Trilogy4_15 and the “old” version as Trilogy.• Only one version can be active at any time and this is located in the directories named“Trilogy” and “Borland”.• This process will leave entries in the “Add Remove Programs” dialogue box, whichcannot easily be removed. These do not cause any harm.Now follow steps 4 and 5 from the preceding Chapter.Page 132 of 132 Issue 1 Trilogy Communications Limited

PathFinder Version 4.22 User Guide21.3 Open PathFinder‣ Start PathFinder by double clicking the icon.‣ Follow the options to create a new (blank) database. All of the Options | Settings will beat their default values. Following the notes taken in Chapter 21.2 (step 2), change thesettings to their previous values.‣ Follow the prompts to Save the settings and re-start the PathFinder application. It is notnecessary to save the configuration file since this is presently a blank database.Following an upgrade, any existing configurations must be converted to the new data format.Follow the instructions for the Conversion Utility given in Chapter 22.3.Trilogy Communications LimitedIssue 1Page 133 of 133
