Crestron MC2E 2-Series Professional Media Controller
NOTE: An optional power pack (PW-2420-RU) provides 38 Watts to Cresnet
devices when connected to the MC2E.
NOTE: In larger system configurations that require more than the 38 Watt load
capacity supplied by Cresnet (when using optional PW-2420RU power pack),
disconnect the +24VDC Cresnet wire from the MC2E and provide the +24VDC
power to the peripheral devices by an alternate source. Refer to page 15 for more
information.
NOTE: Interface connectors for the NET, Infrared-Serial, I/O, and Relay Output
ports are provided with the unit.

24VDC, 2.0A (Power Supply)

24VDC
2.0A
This female connector can be used to supply 24 VDC power to the MC2E from the
included external power pack, (model PW-2410RU) or the optional power pack
(model PW-2420-RU).
When power is supplied to the MC2E through this connector using the included
external power pack, 14 Watts are available to Cresnet devices through the NET
connector. When using the optional PW-2420RU power pack to power the MC2E, 38
Watts are available to Cresnet devices through the NET connector. This is typically
used in small installations.
CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do
so could cause equipment damage or void the Crestron warranty.
NOTE: When power is supplied through this connector, Crestron recommends
disconnecting the +24 VDC on the Cresnet connector.
NOTE: Use care in wiring installations to avoid applying 24 VDC power to Cresnet
wiring from multiple sources.
Memory
The MC2E has 36MB of built-in memory (non-volatile and volatile). The total of
36MB is specified as follows: 4MB flash (non-volatile), 32MB SDRAM (volatile),
and 256KB NVRAM (battery backed up). Flash memory contains the file system
inside the 2-series control engine. Non-volatile memory contains information that is
retained after the loss of electrical power. Volatile memory is lost after a power
failure. Refer to the lists below for a breakdown of memory usage for program-
related information stored in the unit.
