COM Ports
There are eight ports designated for RS-422 communications. They can all be used
to control channels on the server. COM port 7 or 8 can be used to connect a VTR.
COM ports 1 - 8 can be configured to control various channels (see Table 2-4 ).
Each COM port can control only one channel. The COM ports are codec based,
therefore codec 0 = channel 1, etc. For more information on configuring COM
ports, see
NEXIO AMP RS-422 Pinouts on page 115.
