Selecting the rear panel Remote port protocol and baud rate
This procedure affects the rear panel Remote port only. The front panel
Configuration (RS-232) port’s variables can be changed under serial port or
Ethernet control only. See the Command/Response table for IP SIS commands,
in chapter 4, “Programmer’s Guide”, to configure either port under SIS
control.
The Remote port settings are protected when front panel lock mode 2 is
selected. You can view the settings in lock mode 2, but not adjust them from
the front panel.
The switcher can support either RS-232 or RS-422 serial communication protocol,
and operate at 9600, 19200, 38400, and 115200 baud rates. The settings of these
variables can be viewed and changed from the front panel.
