COMMAND CODE STRUCTURE AND DELIMITERS
All commands sent to the CD100 must contain a leading code, the command code, and an ending
code. Each command must be completely executed before the unit will accept a new command. The
unit can be set to recognize six sets of leading and end codes (delimiters) when using an RS-232
remote: parentheses ( ), brackets [ ], braces{ }, slashes \ /, less and greater than < >, and signs !#.
The factory default serial delimiters are [ ].
Note: The CD100 will ignore commands with no delimiters or the wrong delimiters.
A complete command consists of:
[
The leading code
CH3
The command code.
]
The ending code
Example: [CH3] directs the CD100 to select channel 3.
SERIAL CONTROL CABLE WIRING
When controlling only one Court Director System, connect the RS-232 cable as follows:
Controller Transmit
to
CD100 Receive
Controller Ground
to
CD100 Ground
Controller Receive
to
CD100 Transmit
When controlling multiple Court Director Systems, connect the RS-232 cable as follows:
Controller Transmit
to
Each CD100 Receive
Controller Ground
to
Each CD100 Ground
Controller Receive
to
Only one CD100 Transmit
When controlling multiple units, the Controller Receiver Terminal and each
CD100 Transmit Terminal is left unconnected. The CD100 Transit Lines
may not be connected together, otherwise signal contention from multiple
units will result. Therefore, “receive” information is not avail-able to the
controller in this configuration. Each unit must be set to different delimiters.
Court Director™ System Serial Commands*
Note: If the judge override function is active, the only serial commands that may be executed are:
ACIx, CMDCDx, OVERx and RESx. The INVALID MODE response will be given to other commands.
