MLS RS-232 port — This port can control an optional Extron
switcher or other RS-232 controllable device.
If you connect an optional switcher (such as an Extron
MLS Series switcher) to the MLC, you must connect a ground
wire between the switcher and the MLC, as shown in the
following diagram.

LAN connector and LEDs (IP model only) — An Ethernet
connection can be used on an ongoing basis to control the
MLC 104 IP (and the devices connected to it) in an Ethernet
network.
Use a straight-through cable for connection to a switch,
hub, or router.
Use a crossover cable for connection directly to a PC.
Configure the settings for this port via either SIS commands, an
embedded Web page, or Global Configurator.
LAN port defaults are as follows:
• IP address: 192.168.254.254
• gateway IP address: 0.0.0.0
• subnet mask: 255.255.0.0
• DHCP: off
