5.3.3Allegiant System Command Scripts for RS-232 Model Keyboards

When a keyboard is being connected to an Allegiant’s Console port, or an Allegiant Printer port configured to operate in the Console mode, the Allegiant must be preprogrammed so the port will operate in the RS-232 keyboard mode.

The mode of the Allegiant’s Console port can be changed either by a manually entered ASCII text command, or preprogramming the Allegiant CPU with an Allegiant Command Script. The Command Script method is preferred since the appropriate settings are automatically restored after a system power loss or reset. Manually entered commands remain valid only until the system is reset or powered off/on, so typically they should be used only for temporary or test purposes.

To manually configure an Allegiant’s Console port to operate in the keyboard mode, it is necessary to connect to the system via Windows® HyperTerminal or another dumb terminal emulator.

NOTE: Allegiant Console and Printer RS-232 ports do not use a standard RS-232 pinout. Use of an Allegiant Console cable is recommended (If necessary refer to the Allegiant Console cable pinout reference at the end of this manual).

The Allegiant RS-232 settings are user-programmable, but the default settings are:

•

Baud

19,200

•

Stop bits

1

•

Data bits

8

•

Parity

None

•

Handshake

None

Once online with the system, an Allegiant prompt appears each time Enter is pressed. The prompt will look as follows:

TC8x00 >

where x is a digit from one to nine (varies based on the Allegiant model being interfaced)

At the system prompt, manually enter the appropriate command, based on the Allegiant port in use, and type of keyboard interface. Refer to the table below to determine the correct command. Enter the command exactly as shown below, then press ENTER.

Modem connected to Console port (LTC 8900 only)

Command: SET-PORT-RS232 4 4 8 0 1 1;_SET_KBD_MODE 4 1

After entering the command, the port will immediately begin to operate in the keyboard mode. The port will generate a series of constantly repeating codes. The setting remains in effect until the system is reset, powered off/on, or manually cancelled by entering Ctrl-C several times, using Windows HyperTerminal program operating at 9600 baud.
