This procedure works for the rear panel Remote port
only
. The front panel
Config port’s protocol can be changed via SIS command control only. See the
Command/Response table for SIS commands, in chapter 4, “Programmer’s
Guide”, to configure both ports under SIS control.
The switcher’s rear panel Remote port can support either RS-232 or RS-422 serial
communication protocol, and can operate at 9600, 19200, 38400, and 115200 baud
rates. The settings of these variables can be viewed and changed from the front
panel.
View and configure the switcher’s remote port’s serial communications settings as

The flashing Control LED indicates the baud rate as follows:
Enter — 9600
Preset — 19200
View — 38400
Esc — 115200
The flashing I/O LED indicates the protocol as follows:
Video — RS-232
Audio — RS-422
In this example, the port is set to RS-232 at 9600 baud.
