Extron electronic 450 Plus Series Selecting the rear panel Remote port protocol and baud rate

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.
