Typical RS-232 Device Interconnections
The table below shows the typical hookup for RS-232 control of the IT-VCM module. Connections for
loopthrough applications are included.
The Serial-In port is configured for 38,400 baud, 8 data bits, 1 stop bit, and no handshaking. Serial-In
configuration cannot be changed. The Serial Output baud rate can be changed via the Serial 2 baud rate
request “SBA”.
Information on RS-232 protocol is detailed in the serial protocol manual included.
