Both digital input and output modes of the digital I/O ports
have the ability to turn on an internal pull-up resistor to
+ 5 VDC (equivalent to SW2 on the previous illustration).

Refer to the MLC 104 IP Plus User's Manual for further
details on configuring this port.

MLS RS-232 connector — 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.

Power the controller via an external power supply, not
from an Extron switcher. The controller requires a
separate 12 VDC power supply.

LAN connector and LEDs — An Ethernet connection can be
used on an ongoing basis to control the MLC 104 IP Plus (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
