Panel Features and Cabling
Config (Host) Port Cabling
NOTE:
Extron recommends configuring and controlling the MLC via the LAN connector
on the right side panel. Ethernet connections are faster and more reliable.
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 (see figure below). 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 can be used for this
connection.

To/From the
RS-232 Port
on a PC
This port supports bidirectional RS-232 (-5 to +5 VDC)
communication.
Protocol:
• 38400 baud
• 8 data bits
• 1 stop bit
• no parity
• no flow control
Config Serial (RS-232) Port
Front panel Config port:
• RS-232 only (Tx, Rx, ground)
NOTES:
• Use the front panel Config port only for
sending basic SIS commands (such as those
for IP setup and troubleshooting) and
checking unit information and responses.
• You must use the LAN port (not the Config
port) to set up the MLC and upload GC
configuration files or firmware.
NOTE:
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 DataViewer,
HyperTerminal, or a similar application, make sure the PC or control system
connected to these ports is set for 38400 baud.
