APPENDIX B -
REMOTE CONTROL OPERATION
RS-232 Remote Control Interface
The multiplexer has a built-in RS-232 serial interface which supports remote control operation
through simple ASCII commands. The commands provide access to the front panel button
operations just like the IR remote control.
The multiplexer serial interface is fixed at 9600 baud, 8-bit, 1 stop bit, and no parity. The
command format is:
command - return
The command is 2 characters or 2 characters plus parameter, and must be followed by a
“carriage return”.
The multiplexer will respond with:
> if the command was recognized, or
? if the command was not recognized or is invalid
