2-Series Professional Media Controller Crestron MC2E
NOTE: For laptops and other PCs without a built-in RS-232 port, Crestron
recommends the use of PCMCIA cards, rather than USB-to-serial adapters. If a
USB-to-serial adapter must be used, Crestron has tested the following devices with
good results:
Belkin (large model) F5U103
I/O Gear GUC232A
Keyspan USA-19QW
Other models, even from the same manufacturer, may not yield the same results.

An 8-position RJ45 port (labeled LAN ) is accessible on the connector panel at the
rear of the MC2E. The port is used for connection to the Ethernet, providing local
area network or Web access (cable is not supplied). The port also contains two light-
emitting diodes (LEDs). The LED on the left side of the port is a link status LED
and illuminates when the card is connected to a working network. The LED on the
right-side flashes to indicate Ethernet activity. Refer to the following table for the
Ethernet connector signals and use an appropriate cable (not supplied).

This connector is used for expansion to Cresnet peripherals. This connector can also
serve as a 24V power source to Cresnet devices when the MC2E is powered by the
external power pack, PW-2410RU;. There is a 14 Watt maximum load rating for the
Cresnet power output when used with the included power pack PW-2410RU. Refer
to “Network Wiring” on page 13 for details. If the external power pack is not used,
the MC2E can receive power from a Crestron power supply from this connector.
