Crestron CP2/CP2E 2-Series Integrated Control Processor
24VDC, 2.0A (Power Supply)
24VDC
2.0A
This male connector can be used to supply 24VDC power to the CP2/CP2E from an
AC power pack purchased separately. (Refer to Optional Power Supply on page 13).
When power is supplied to the units through this connector, 24VDC, 24W is also
available to other Cresnet system devices through the NET connector. This is
typically done in small installations. In large system configurations, power is usually
supplied through Cresnet wiring to the NET connector.
NOTE: Use care in wiring installations to avoid applying 24 VDC power to Cresnet
wiring from an AC power pack as well as from a system device that contains its own
power supply. Although this condition should not cause any damage, Crestron does
not recommend it. In those network configurations that require more power than can
be supplied by Crestron’s Power Control Unit alone, disconnect the +24 VDC
Cresnet wire from those devices that will be powered by an AC power pack.

Memory
The CP2/CP2E has 36MB of built-in memory (non-volatile and volatile). A total of
36MB is broken down as follows: 4MB flash (non-volatile), 32MB DRAM
(volatile), and 256KB NVRAM. Flash memory contains the file system inside the 2-
