Remote switching control
The port switching functions of the ServSwitch CX Quad
IP unit can be remotely controlled by an RS232 link to the
OPTIONS
port on the rear panel.
The sending device must use the following RS232
communication settings:
Baud rate: 19200 bps
Data bits:
8
Parity:
None
Stop bits:
1
No handshaking is implemented, however, valid command characters will be
echoed back to the sending device.
Note: You must ensure that the ServSwitch CX Quad IP
unit has it Options serial
ports set to ‘Sync Units’. This setting (together with the baud rate selection) can
be made either via the
or
user configuration menus.
The value of the byte received via the serial link determines which computer port
should be linked through to the user port. The table given here summarizes the
valid control codes:
