12VDC .5 A
This DC power socket connector is used to supply power via an external power pack.
Crestron recommends specific power packs for its devices. The recommended power
pack for the CEN-CN is Crestron part number PW-1205 (PWI-1210 for
international use). If a power pack other than this Crestron model is obtained, verify
that it meets the required specifications and polarity as shown after this paragraph.

This 6-pin, 6-position RJ11 modular jack is used to communicate with a PC when
performing the configuration of the CEN-CN or for troubleshooting diagnostics.
Refer to the table below for the pinouts. Specifications to fabricate a CEN-CN to PC
cable are provided on page 7.

The NET 6-pin, 6-position RJ11 modular jack is used for expansion to SmarTouch
peripheral(s) or modular Cresnet devices. Refer to the table below for the pinouts.
This port is connected in parallel to the 4-pin network connectors described below.
CAUTION: If making connections to RJ11 ports, use the Crestron 6-conductor
modular cable provided, DO NOT use 6-conductor telephone cables. Telephone
cables are wired in a crisscross fashion and are not compatible with Crestron
equipment. For further information, refer to the latest revision of Modular Cable
Requirements (Doc. 5682). This document can be obtained from the Downloads

NOTE: The +24VDC at this port is available only if supplied via Cresnet wiring connected to
the 4-wire NET port(s). The external AC power pack does not supply power to this port.
The two NET 4-pin network connectors are used to connect the 4-wire Cresnet
devices to the CEN-CN. Power can be provided via the NET connection and the
external power pack is not required. Refer to “Cresnet Network Wiring” on page 5
for wiring information.
