RS-232 Commands
Crosspoint Commands
A Crosspoint command sends inputs to outputs. The command structure is simple:
> [Unit] [Crosspoint (X, A, V)] [Input (0-6)] [Output (A-D)] [Input] [Output]…
More than one set of Input/Output points can follow the Crosspoint command. You don’t have to include all
Input/Output Crosspoints in the string, only the Crosspoints that need to be changed. A carriage return is
required at the end of each command and is assumed in all examples.
