Chapter 1: OverviewCompatibilityThe NCR RealPOS 5953 PS/2 DynaKey is a Point-of-Sale (POS)keyboard with a built-in 12.1-inch SVGA flat panel Liquid CrystalDisplay (LCD). The 5953 comes with a passive matrix (DSTN) colorLCD or an active matrix (TFT) color LCD. Touch Screen is alsoavailable as an option. Unique to the DynaKey is a set of “DynaKeys”located beside the LCD. These keys change function depending on thesoftware application appearing on the LCD. Also unique are twoup/down scroll keys.The keypad module contains configurable key matrix, DynaKeys, andscroll keys.The NCR 5953 DynaKey is designed as an optional Input/Output(I/O) device for the following workstations:• NCR 7452 retail workstation (non-586 motherboard)• NCR 7453 retail workstation (non-586 motherboard)• An Intel-based PC with an available standard PCI slot (the LCDboard has been tested and found to be compatible with a widevariety of standard PCs)17089

1-2 Chapter 1: OverviewFeaturesThe NCR 5953 DynaKey contains either a 12.1-inch passive-matrix(DSTN) or a 12.1-inch active-matrix (TFT) color LCD. In addition to theLCD and the keypad, the unit includes the following features:• Resistive touch screen (option)• External decoded RS-232 scanner connector• Multi-color power status LED• LCD contrast control (not on active matrix TFT units)• Keylock• Three-track ISO Magnetic Stripe Reader (MSR) (option)• Speaker (separate from the PC speaker)• External standard PC keyboard connector• Special “PC Setup” keypad layout• Integrated 2 x 20 Customer Display (option)• Integrated keypad

Chapter 1: Overview 1-3Wedge ControllerThe Wedge consists of a microcontroller and associated circuitry thatsupports (via a PC standard keyboard interface) the followingperipheral devices:• A Magnetic Stripe Reader (MSR)• Decoded RS-232 Scanner• Keylock• SpeakerThe controller logically connects these devices with a standard PCkeyboard. The retail workstation or PC interprets the data flow askeyboard input.An application can use special start and end sentinel characters todetermine that the information actually came from the Wedge deviceinstead of the keypad or external keyboard.On a retail terminal or PC workstation, the Wedge also controls theoperation of the built-in speaker (not the PC speaker).For more information on the Wedge, refer to the NCR Wedge SoftwareUser’s Guide, BD20-1368-B.

1-4 Chapter 1: OverviewDecoded ScannerMulti-Color Power LEDThe DynaKey permits a standard decoded RS-232 bar code scanner toinput data via the keyboard data stream. The scanner port alsoprovides +5V power to permit easy scanner connection.Note: Scanners connected to the Wedge RS-232 Scanner Port shouldbe configured to operate at 1200 bps if there is any possibility ofscanning activity simultaneous with keyboard or mouse input. Athigher baud rates, scanner data may be lost if the wedge controller isbusy processing input from the keyboard (including DynaKeys) ormouse.On the face of the DynaKey is a multi-color power LED. The status andcondition indicated by the LED are shown as follows.StatusGreenRedOrange*Flashing red/greenOffConditionDynaKey power onWedge controller reporting an error conditionLCD in standby mode (or see note below)DynaKey keypad in “PC Setup” mode(See Special Keypad mode in Installation)DynaKey power offNote: The LED may also be orange for a few seconds on power-upbefore display is active.

Chapter 1: Overview 1-5LCD Contrast ControlThe passive DynaKey has a manual contrast control knob to adjust theLCD Contrast for temperature changes and different viewing angles.Warmer temperatures cause the LCD to lighten. The LCD darkenswhen colder.Note: The contrast control knob is located on the access cover.Keylock PositionsThe DynaKey includes a standard NCR Keylock, accessible through theWedge controller.There are four positions: Exception, Locked, Retail, and Supervisor.They are explained in the following table.Abbreviation Position DescriptionEx Exception Used by the customer or service representativeto perform low level programming such asworkstation diagnostics, configuring theworkstation, or loading the workstation.L Locked Used to lock keyboard input to prohibit use ofnormal functions.R Retail Used when performing normal retail modefunctions.SSupervisor Used by the supervisor to provide highest levelof workstation control in cases such as refundsand running totals.

1-6 Chapter 1: OverviewExternal Standard PC Keyboard ConnectorBecause the DynaKey does not have alphanumeric keys, a standard PCkeyboard can be connected externally to the DynaKey whenever PCinput is required. The PC perceives only one keyboard input, but theDynaKey passes commands from the external keyboard to the hostworkstation.Special “PC Setup” Keypad LayoutOn power-up, the operator can switch the DynaKey into an alternatekeypad layout that can be used with many PC BIOS setup andconfiguration routines. The alternate layout contains keys such as ESC,TAB, END, “+”, “-” and arrow keys which are not available in thenormal keypad layout. The alternate layout allows the operator toconfigure a PC without an external alphanumeric keyboard. (See theInstallation chapter.)Three-Track MSR or Two-Track JIS MSRThe 5953 includes an optional integrated International Organization forStandardization (ISO) three-track analog MSR head or a two-track JISMSR head.SpeakerThe 5953 includes a built-in speaker. By default, it sounds key clicks,but it can be programmed through the Wedge to sound tones undercontrol of the application program. The speaker is tied to the speakercontrol of the 7452/7453 Workstation so that whenever the 7452/7453speaker sounds, so does the 5953 speaker.

Chapter 1: Overview 1-7Integrated 2 x 20 Customer DisplayThe Model 5953 supports an optional integrated 2x20 VFD customerdisplay. The 5972-F039 Integrated Post Mount includes a special rearcover for the 12.1-Inch DynaKey table top mount that allowsattachment of the 5972-1000 2x20 Customer Display Post Mount. Thisspecial rear cover is used with the 5953-F023 table top mount forcustomer display (which does not include a rear cover), or replaces thestandard rear cover that is shipped with the 5953-F022 and 7452/7453-F451 12.1-Inch DynaKey Table Top Mount.

Turn the Keylock on the DynaKey to the Ex position.3. Power on the system.Special Keypad ModeThe BIOS setup routine requires keys that are not present in the regularDynaKey keypad layout (such as the ESC and End keys). Although theDynaKey has a PC keyboard port, a PC keyboard may not be readilyavailable to the operator. To use the DynaKey to run setup routines,you can place the DynaKey into a special alternate layout mode thatreplaces the normal layout of the keypad and function keys. To enterthe special Setup Keypad Mode, proceed as follows:

Chapter 3: Installation 3-231. Power up the system.2. After the memory test completes, hold down key number 10 andkey number 12 simultaneously. Make sure both keys are held downtogether. The 10 and 12 keys must be the first two keys pressedafter a power on. If any other keys are pressed first, pressing the 10and 12 keys simultaneously will not put the DynaKey into theSetup Keypad Mode. The status LED flashes red/green to indicatethat the keypad entered the Setup Keypad Mode.3526F1342728293031F21 2 34 5 67 8 9Tab End10 11 12 1378914 15 16 174 5 618 19 20 211 2 3F1F2ESC3222 23 * 24 250 Del .

Press the [F2] key to put it into the BIOS configuration routine.4. Use the special keypad layout to run the system’s BIOSConfiguration routine.Note: The DynaKey Setup Keypad Mode is provided simply as aconvenience feature. If you prefer not to use this mode, simply connectan external keyboard to the DynaKey keyboard port to use for systemconfiguration.

Chapter 3: Installation 3-25Normal Operating ModeAfter setup and configuration, the keyboard can be reset to exit thespecial keypad mode. This is done by power cycling the DynaKey, orpressing the 10 and 12 keys simultaneously. This puts the keyboardback into its normal operating mode as shown. Usually keys 22 - 23and 21 - 25 are capped together by default.3526272829F1F2F3F4341 2 3Shift-F1 Shift-F2 Shift-F34 5 6Shift-F4 Shift-F5 Shift-F67 8 9Shift-F7 Shift-F8 Shift-F1010 11 12 137 8 9 Cntl-F130F514 15 16 174 5 6Cntl-F23132F6F718 19 20 211 2 322 23 24 25Cntl-F30 Shift-F9 .CR33F817195bNote: Numeric keypad is shown in calculator layout.

3-26 Chapter 3: InstallationScreen Saving FeatureThe display has a time-out function that causes the display to go blankafter several minutes of inactivity. The screen saving feature iscontrolled by NCR platform software integrated into the 5953 drivers.Note: If your screen saver is active and the Keylock is in the Lposition, you may need to put the Keylock into another position toun-blank the LCD.When a key is pressed to return the display from screen saver mode,the resulting keystroke is passed to the application by default.

The software CD includes Touch ScreenDrivers, Utilities and Manuals.The NCR 74xx Base System and Client 3 rd Party Drivers (D370-1111-0100)includes the software from G370-0525-0000, G370-1289-0000, andG370-0835-0000. This SOFTWARE CD includes configuration andcalibration utilities for the MicroTouch touch screen for DOS, Win 3.11,Win 95, Win 98, and Win NT.The Microcal utility does not support calibration for 800 x 600 (SVGA)resolution under DOS or Windows 3.x environments. The GetSet3utility is required to calibrate the 12.1” Touch Screen with 800 x 600resolution under DOS and Windows 3.x environments.While the GetSet3 Utility provides other functions, only the calibrationfunctionality should be used. Please refer to the Restrictions Fileincluded with the GetSet3 utility.• For Windows 95 and NT environments use the Windows StartMenu at: START/PROGRAMS/MICROTOUCH/TOUCHWARE CONTROLPANEL• For more information on the Touch Screen controller and firmwarecommands, contact3M Touch Systems3M Optical Systems Divisions501 Griffin Brook Park DriveMethuen, MA 01844(978) 659-9000.

4-2 Chapter 4: ProgrammingNote: Whenever an application or driver turns the backlight off or on,it should also reset the Touch Controller (send a RESET command).This ensures that the noise generated by the sidelight is nulled anddoesn’t affect touch accuracy.12.1-Inch DynaKey Video DriversWhen using 12.1 displays the required video drivers depends on whichclass-model of the terminal that it is configured with or if the display isbeing used with the C&T 69000 LCD SVGA Video Adapter card. Thedrivers are available on NCR software CD; NCR 74xx-Base and SystemClient 3rd Party Drivers, D370-1111-0100 (previously, G370-0830-0000).Drivers and installation instructions are available on this software CDfor Win. 3.1, Windows 95, Windows NT 4.0 and Windows 2000.Drivers are not needed for DOS.If the display is being used in a Dual Display configuration, refer to theCID User's Guide (BD20-1331-B) for specific OS, driver, and installationinformation.

Chapter 4: Programming 4-3Device InterfacesThis chapter provides information on the device interfaces, including:• Wedge Controller• Touch Screen• Analog MSR• RS-232• PS/2 KeyboardWedge Controller Interface• Keyboard FirmwareCaution: When performing touch screen calibration on the 5953DynaKey under Windows 95, note that if the terminal is shut downimproperly the calibration may be lost. To avoid this situation, verifythe terminal is properly shut down after calibrating the touch screen.To shut down correctly, select the START button in the lower leftcorner of the screen, and then select SHUTDOWN. When the terminalis powered up, the recent settings will be retained.This procedure is especially important during initial calibration of thedisplay in order to ensure that at least a base set of reasonablecalibration parameters are preserved in the Windows 95 Registry.The Wedge consists of the following.• Microcontroller and its associated circuitry that supports athree-track ISO or a two-track JIS Magnetic Stripe Reader (MSR)• Keylock.The Wedge merges the data into the keyboard data stream.

4-4 Chapter 4: ProgrammingThe data arrives at the retail workstation or PC as if someone hadentered it directly through a keyboard. An application can use specialstart and end control characters to determine that the informationactually came from the Wedge instead of the keypad or externalkeyboard.The Wedge also controls the operation of the built-in speaker (not thePC speaker) and the status LEDs.For more information on the Wedge, refer to the NCR Wedge SoftwareUser’s Guide, BD20-1368-B. Contact your NCR sales representative toorder this book.Touch Screen InterfaceThe Touch Screen module connects to the 7452 or 7453 retailworkstation or a PC through the external connector on the PCI LCDboard.The Touch Screen firmware defaults to the following communicationsparameters:• 9600 baud• No parity• 7 data bits• 2 stop bit• Auto baud disabledThese parameters may be changed by the MicroTouch drivers. To setthem, use the MicroTouch MicroCal program.Please refer to the MicroTouch Drivers and Utilities section for asoftware explanation.Analog MSR InterfaceThe analog MSR interface sends data to the workstation or PC throughthe Wedge controller. The data is amplified and then formatted by thewedge.

Chapter 4: Programming 4-5RS-232 InterfaceThe RS-232 interface allows connection of RS-232 devices such as adecoded laser scanner. The connector provides the RS-232communications lines and +5V and GROUND. Most scanners do notrequire an external power supply. The DynaKey reads the scanner dataand places it in the keyboard data stream. Only scanners certified byNCR should be connected to this interface.PS/2 Keyboard InterfaceA PS/2-style keyboard connector permits alphanumeric entry and nontouchapplications to be used through a standard PC keyboard. Youcannot connect and use a Wedge Keyboard in this port.Note: The keylock is not available as a pass-through interface. Youcan only access it through the Wedge controller.Keyboard FirmwareThe DynaKey firmware consists of standard IBM PS/2-compatiblekeyboard firmware with added extensions for POS-specific functions.The DynaKey supports the following minimum standard PC keyboardcapabilities:• Multi-key rollover (3-key minimum)• Optional system reset (Alt-Control-Delete) at the externalkeyboard (default=enabled)• Keyboard buffering (32 bytes)Additionally, the DynaKey has capabilities unique to the POSenvironment. The DynaKey keyboard contains extensions for thefollowing added POS-specific functions:• Keyboard auto-repeat for numeric and cursor control keys only (forexample, no auto-repeat for function keys and DynaKeys).• Automatic detection of double high/wide keys (default = enabled).

4-6 Chapter 4: Programming• Firmware command for user configuration of the numeric keypadfor either “calculator” or “telephone” arrangement.• Firmware command for user configuration of double high/widekeys (and keypad layout for backward compatibility). Takesfirmware out of “double high/wide auto detection” mode.• Firmware command for the controller to return its NCR partnumber.• Firmware command for enabling and disabling the system reset(Alt-Control-Delete) sent by the external keyboard. The defaultsetting is determined by the state of an external I/O pin on thekeyboard microcontroller (default=enabled).• Special “PC Setup” alternate keypad layout so the DynaKey can beused to run PC BIOS configuration routines.Command SetThe host workstation does not recognize two keyboards. However, anexternal keyboard can be connected to the DynaKey, and the DynaKeypasses the commands to the host workstation.Note: The connection of an external keyboard to the DynaKey isoptional.You can use the POS commands only for communication between theDynaKey and the host system. The POS commands are not passedthrough to an external keyboard.

Chapter 4: Programming 4-9POS DefaultsDuring power up, the host workstation initializes the keyboardfirmware by generating a keyboard reset. While this reset is active orthe keyboard power is rising, the keyboard will be locked andprohibited from execution by the keyboard hardware.Upon powering up or receiving a reset, the keyboard initializes byclearing RAM, clearing internal indicators, resetting the indicator lights(if any), and performing keyboard diagnostic tests. Additionally, thekeyboard performs initialization diagnostic tests to ensure validoperation of the keyboard.These diagnostic tests check the keyboard ROM and RAM, and theydetect stuck keys on the keyboard. If the ROM or RAM tests fail, thekeyboard attempts to return an error status. If a stuck key condition isdetected, the make key code of the stuck key is returned following thesuccessful status (AA Hex).Following is a list of Power Up and Reset POS default conditions:• Calculator numeric keypad configurationAuto detection of double high/wide keys enabled.• Alt-Control-Delete protection default at power-up is determinedby examining I/O pin P2.7 on the keyboard microcontroller. (Referto table in the Alt-Control-Delete section.) Alt-Control-Delete isdefault enabled.

Chapter 4: Programming 4-11When the operator presses a key on the DynaKey that requires theNum Lock to be “on” (i.e., the numeric keys and the “.” key), thefirmware examines the current state of its Num Lock Flag and does oneof two things:NUM LOCK “OFF”Send NUM LOCK key codes, then keypad key codes.The DynaKey sends make-and-break codes for the Num Lock key (toturn Num Lock “ON”) and then the keypad key codes. (Note that theDynaKey firmware keeps track of the Num Lock state with an internalNum Lock Flag that is set according to the host Set/Reset ModeIndicators command. Note also that the Set/Reset Mode Indicatorcommand is passed-through to the external keyboard, if attached.)After sending the Num Lock and keypad codes, in the event that theDynaKey does not receive a Set/Reset Mode Indicators response fromthe host before another keypad key is pressed, the DynaKey simplysends another Num Lock code sequence followed by the keypad keycodes.NUM LOCK “ON”Do not send NUM LOCK codes, simply send key codes. The DynaKeysimply sends the correct scan code for the key that was pressed. Thisscenario does not change if no external keyboard is attached.Many keys on the DynaKey do not change state with the Num Lockmode. Obviously, for those keys, there is no need to check the NumLock Flag first before sending their key codes.The host terminal should not be able to tell that two keyboards existwhen an external keyboard is plugged into the DynaKey. TheDynaKey appears to the host system as one keyboard whether or notan external keyboard is attached.

4-12 Chapter 4: ProgrammingCursor Control at the DynaKeyAlt-Control-Delete ProtectionThe up arrow and down arrow keys are patterned after the cursor keyson an IBM PS/2 101 keyboard.The simultaneous depression of the Alt, Control, and Delete keys onthe external keyboard results in a PC system reset or reboot. Topreserve security in a POS environment, it may be necessary to restrictthe system-reset function to avoid an unnecessary reboot of the system.The default state of the Alt-Control-Delete disable function after akeyboard reset is determined by examining the state of the 2.7 I/O pinon the keyboard microcontroller.Pin State Alt-Control-DeleteP2.7 High (1) Enabled (default)P2.7 Low (0) DisabledAlt-Control-Delete DisabledThe host can disable the Alt-Control-Delete with the followingcommand:Command ParameterE9 00After a reset, the DynaKey keeps track of the state of the Alt, Control,and Delete keys (whether they are pressed down or not) with threebits in its on-board RAM.After the host issues the Alt-Control-Delete disable command, if anytwo of the three keys are down, the DynaKey does not pass-throughthe make code for the third key from the external keyboard.

Chapter 4: Programming 4-13Alt-Control-Delete EnabledFor example, if the DynaKey sees the make code for the Delete key, itchecks its on-board RAM to determine the state of the Alt and Controlkeys. If it determines that the Alt and Control keys are also down, thenthe DynaKey does not pass through the make code for the Delete keyon to the host system. It discards the Delete make code.The codes for the Alt-Control-Delete key sequence need not arrive atthe DynaKey in sequence. Other key make-or-break codes could arrivebetween the make codes for the sequence. Note that any combinationof Alt-Control-Delete causes a system reboot.The firmware is capable of insuring that the operator is not able toreboot the system by holding down the Alt, Control, and Delete keyson the external keyboard at any time, in any sequence, and incombination with any other keys.The Alt-Control-Delete feature is enabled when the host issues thefollowing command:Command ParameterE9 01Upon receiving this command, the DynaKey firmware allows the Alt-Control-Delete scan codes to be passed through from an externalkeyboard to the host system.

4-14 Chapter 4: ProgrammingCalculator or Telephone Numeric Pad LayoutEither of two commands (EA or E9) can be used to switch the layout ofthe numeric keypad on the DynaKey from the traditional calculatorstylelayout to a telephone-style layout.The EA command takes the DynaKey out of Autodetect DoubleHigh/Wide Keys mode. EA requires that the host system sendblocking key information to the DynaKey along with the numerickeypad layout information. The EA command is primarily used forbackward compatibility of the DynaKey with previous NCR retailworkstations.The E9 command only changes the numeric keypad layout. It does notaffect automatic double high/wide key detection.Command ParameterE9 02 (Telephone)E903 (Calculator, Default)Upon receiving the E9 command and 02 parameter combination, theDynaKey switches from the default calculator numeric keypad layoutto the telephone numeric keypad layout. If the host needs to restore thedefault calculator layout, it sends the E9 command and 03 parameter.Note: Changing the numeric keypad layout also requires physicallyremoving and swapping the key caps on the first and third rows of thekeypad. The key codes for the DynaKey’s numeric keypad are the sameas the numeric keypad on an IBM PS/2 101-key keyboard.After each reset, the host workstation can issue either the E9-02command or the EA Keyboard Options command to specify thetelephone numeric keypad configuration.

Chapter 4: Programming 4-15Detection of Double High/Wide KeysSeveral keys on the DynaKey keypad can accept optional key tips thatcover two keys to produce double high or wide keys.When you press a double high/wide key tip, the DynaKey firmwaresends only one of the two keys’ scan codes to the host system.The DynaKey supports two methods of double high/wide keyoperation:• Auto-detection of double high/wide key mode (default)• NCR POS-compatible double high/wide key configuration modeAuto Detection of Double High/Wide Key Mode (default)In this mode of operation, if you press a valid double high/wide keycombination simultaneously (for example, one key is pressed within 18ms of the other), the firmware sends only one scan code to the system.The scan code sent is the code for the key that is not the blocking key inthe double high/wide pair.For example, if a double high Enter key tip is placed over keys 21 and25, and you press the double high key tip, then the firmware sees thatboth keys 21 and 25 are being pressed within 18 ms of each other. Thefirmware knows that the key 21 and 25 combination is a valid doublehigh key pair and that key 21 is a blocking key. Therefore, the firmwaresends the make code for only key 25.If you press two or more keys simultaneously (within the 18 mswindow), and the key combination is not a valid double high/widepair, then the firmware does not send the make codes for either key.Instead the firmware sends the 00 (overflow) code -- which causes thehost PC to beep. This is known as double key error detection.

Chapter 4: Programming 4-17NCR POS-Compatible Double High/Wide Key ConfigurationModeThe DynaKey enters this mode after receiving the Keyboard Optionscommand (EA Hex) and remains in this mode until a reset. Asexplained below, this command directly configures the doublehigh/wide key combinations, thus negating the need for the firmwareto auto detect a double high/wide pair. This mode is used primarily tomaintain DynaKey compatibility with previous NCR POSworkstations.Keyboard Options Command EAThe DynaKey firmware supports command-selectable keyboardoptions under user control:• Calculator or telephone arrangement of numeric pad• Activation/deactivation of Blocking Keys• Activation/deactivation of double key error detectionCommandEAParameterByte #1 - Blocking Keys, Telephone/Calculator Keypad,Double Key Error DetectionByte #2 - Blocking KeysByte #3 - Blocking Key PairsByte #4 - Blocking Key PairsNote: Issuing the Keyboard Option command for any reason takes theDynaKey out of Autodetect Double High/Wide Key mode.

4-18 Chapter 4: ProgrammingDouble High/Wide KeysThe keyboard firmware for the DynaKey supports host workstationconfiguration of double size keys and the arrangement of the numerickeypad. The host workstation can also specify deactivation of doublekey error detection. If you want to change any of these options fromtheir default state, the host workstation must issue the KeyboardOptions command to the keyboard following each power up or reset.The Keyboard Options command consists of five bytes. Upon receivingthe command, the DynaKey switches to NCR POS-compatible doublehigh/wide key configuration mode (auto-detection of doublehigh/wide keys is disabled). In typical PC environments, the POSKeyboard Options command is not activated by PC software.However, this capability is in the keyboard firmware for possible PCuse.The first byte is the command byte (EA Hex) which indicates the actionbeing requested from the keyboard.The second and third bytes are parameter bytes that define thearrangement of the numeric keypad; control the double key errordetection; and specify the active blocking keys.The fourth and fifth bytes are parameter bytes that define the keyspaired with the blocking keys to form double-size keys.Note: Adding or changing a single double-size key requires theactivation of the blocking key plus the selection of the second key inthe pair forming the double-size key.For double-size keys, the DynaKey firmware sends only the one activekey scan code to the workstation. The blocking key scan code is notsent.Additionally, if the keyboard firmware detects only the blocking key, itsends only the key code for the specified active key to the hostworkstation. The keyboard firmware ensures that the active and theblocking keys do not both send a key code for one double-size keydepression.

Chapter 4: Programming 4-19Double Key Error DetectionWhen double key error detection is enabled and two or more keys aredetected within an 18 ms period, the keyboard firmware indicates anerror condition in the same manner as a Buffer Overflow (00 Hex).The multiple keys detected within the 18 ms period are ignored by thekeyboard and not sent to the host workstation. Only the bufferoverflow indication is sent to the workstation.When double key error detection is disabled, the keyboard firmwaredoes not perform double key error detection and transmits all keyentries. This permits the workstation diagnostic and configurationsoftware to receive two key codes for double-size keys for initializationof the keyboard. Once the double-size keys are defined, theworkstation configuration software then activates the double key errordetection feature while programming the keyboard for blocking keys.First Byte = Command Byte (EA Hex)Second Byte = Parameter Byte 1 (Blocking Keys, Keypad,Double Key Error Detection)Bit 0 - 0 = Calculator Numeric Pad Arrangement (Default).Bit 0 - 1 = Telephone Numeric Pad ArrangementTo complete the change to Telephone Numeric Pad, Key tips 1, 2,and 3 must be interchanged with Key tips 7, 8, and 9.Bit 1 - 0 = Blocking Key 23 offBit 1 - 1 = Blocking Key 23 activated (Default Double Wide Zero - 0)To complete the change from a double-wide key to two single widekeys, replace the double wide key tip with two single wide keytips.Bit 2 - 0 = Blocking Key 21 offBit 2 - 1 = Blocking Key 21 activated (Default Double High Enter)

4-20 Chapter 4: ProgrammingTo complete the change from a double high key to two keys, the1/2 x 2 high key tip must be replaced by two individual key tips1/2 x 1 high.To complete the change from two keys to a double high key, two1/2 x 1 key tips must be replaced by a double high key tip with aleveling device.Bit 3 - 0 = Double Key Error Detection activated (Default)Bit 3 - 1 = Double Key Error Detection offBit 4 - 0 = Blocking Key 4 off (Default)Bit 4 - 1 = Blocking Key 4 activatedBit 5 - 0 = Blocking Key 5 off (Default)Bit 5 - 1 = Blocking Key 5 activatedBit 6 - 0 = Not usedBit 7 - 0 = ReservedThird Byte = Parameter Byte 2 (Blocking Keys)Bit 0 - 0 = Blocking Key 6 off (Default)Bit 0 - 1 = Blocking Key 6 activatedBit 1 - 0 = Blocking Key 13 off (Default)Bit 1 - 1 = Blocking Key 13 activatedBit 2 - 0 = Not usedBit 3 - 0 = Not usedBit 4 - 0 = Not usedBit 5 - 0 = Not usedBit 6 - 0 = Not usedBit 7 - 0 = Reserved

4-22 Chapter 4: ProgrammingKeyboard Part Number/Type Command (EC Hex)The DynaKey contains keyboard part number and type values in thekeyboard ROM. The DynaKey sends these values to the workstationwhen requested by the Keyboard Part Number/Type command (ECHex). Upon receiving this command, the keyboard firmware performsthe following:• Send ACK to Workstation• Clear Keyboard Buffer• Read Keyboard Part Number and Type from ROM• Send to WorkstationThe Keyboard Part Number/Type format is shown below:Keyboard Part NumberKeyboard TypeThe keyboard part number is a five-character binary coded decimal(BCD) value indicating the NCR part number (10 digits) of thekeyboard ROM chip. This value is within the keyboard ROM.The keyboard part number for the DynaKey ROM is (BCD):49 70 40 65 05 = 497-0406505Note: This part number changes with subsequent noninterchangeablereleases of the DynaKey keypad firmware or majorchanges in the DynaKey unit.The DynaKey sends the most significant two digits to the host as aBCD byte first. The next two digits are sent second. This ordercontinues for the next 3 bytes.For the DynaKey, the keyboard type field is a one-byte field indicatingthe type of keyboard as shown below:Type Keyboard02 Hex DynaKey

Chapter 4: Programming 4-25Panel OFF/ON SequenceBefore turning the Panel Off, turn off the video using SequencerRegister 1 bit 5 (SR01[S]) in the same manner as IBM recommends forthe standard VGA. To make Video Off more effective, some additionaldelay should be included before Panel Off.By turning the Video Off via SR01[5], the Sequencer is no longerrefreshing the screen. This gives the Sequencer enough bandwidth towork with the Panel Off logic to do an orderly shutdown of the videooutput.PCI LCD Board (69000 Chips)Panel Off Sequence:Save Sequencer Register IndexTurn Video Off (SR01[5]=1)Restore SR IndexDelay 15mSTurn Panel Off (FR05[3]=1)Panel On Sequence:Turn Panel On (FR05[3]=0)Save SR IndexTurn Video On (SR01[5]=0Restore SR IndexThese are brief sequence examples.
