Front panel Config (host control) port — For MLC configuration and control,
connect a Windows
®
-based PC or an RS-232 control system to the MLC via
this 2.5 mm mini stereo jack. This port is accessible even after the MLC has
been installed and cabled. The optional 9-pin D to 2.5 mm stereo mini TRS
RS-232 cable (part #70-335-01, shown below) can be used for this connection.

This configuration port requires 38400 baud communication. This is a higher
speed than many other Extron products use. Global Configurator software
may automatically set the connection for the appropriate speed. If using
HyperTerminal or a similar application, make sure the PC or control system
connected to these ports is set for 38400 baud.

For the IP models, Extron recommends configuring and controlling the MLC via
the LAN connector on the right side panel. Ethernet connections are faster and
more reliable.
