Serial Commands- (Forwarding):
The HD4xSTPMX can route commands from the RS-232
port to any connect Zones A-H for controlling the attached display
* RS-232 Forwarding feature will only work when using the RS-232 port of the
HD4xSTPMX. The LAN port does not support RS-232 Forwarding*

Example:
To send a 9600 baud, 10 byte command to Zone H.
Step1:
Send RS-232 Forwarding Command to matrix. This will set up the
matrix to "forward" the next 10 Byte command to Zone H at 9600baud.

The RS-232 port will remain connected to the requested Zone for 1 second
after command has been sent (step 2). This allows for any reply to be
received from the zones. After 1 sec, all zones will be disconnected from
RS-232
