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
