Adder Technology CATX-PS2, X200A/R Remote switching control, Host computer port/channel Video off

Remote switching control

The port switching functions of the AdderView CATx	REMOTE
and AdderView CATx IP units can be remotely controlled
	CONTROL
by an RS232 link to the serial communication port on
the rear panel, labelled as COM1/Upgrade.

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 of the four user ports should be linked through to the 24 host computer ports. Each user port can be individually switched to required ports. The table given here summarises the valid control codes:
