Front panel Configuration port
The front panel Configuration port is hard configured as RS-232 only. The port
can operate at the 9600, 19200, 38400, or 115200 baud rate, but Extron recommends
leaving this port at 9600 baud only.

This port is independent of the rear panel Remote port and is not affected by
changes to the rear panel port’s protocol. This front panel port’s protocol can
be changed via an SIS command only. See the "Command/Response table for
IP-Specific SIS commands", on page 4-23, to configure both ports using an SIS
command.
The optional 9-pin D to 2.5 mm mini jack TRS RS-232 cable, part #70-335-01 can be
used for connection to the Configuration port.
