Remote switching control
The port switching functions of the AdderView CATx 1000
units 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.
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 summarises the
valid control codes:
