Crestron CEN-CN | Ethernet/Cresnet Interface |
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-1210for 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.
Power Pack Specifications
CRESTRON POWER PACK | INPUT SPECS | OUTPUT SPECS |
| | |
PW-1205 | 120VAC~60 hertz (Hz) | 12VDC .5A |
PWI-1210 | 230VAC~50Hz | 12VDC 1A |

PC
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.
PC Port Pinouts
PIN | DESCRIPTION | PIN | DESCRIPTION |
| | | |
1 | CTS (Clear to Send) | 4 | TxD (Transmitted Data) |
| | | |
2 | GND | 5 | RTS (Request to Send) |
3 | RxD (Received Data) | 6 | Not Connected |
NET
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).

6-Pin NET Port Pinouts
PIN | DESCRIPTION | PIN | DESCRIPTION |
| | | |
1 | +24VDC | 4 | NET- (Cresnet Z data) |
| | | |
2 | +24VDC | 5 | GND |
3 | NET+ (Cresnet Y data) | 6 | GND |
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.
