Ethernet/Cresnet Interface | Crestron CEN-CN |
ETHERNET
This 8-pin, 8-position RJ45 port connects the CEN-CN to a 10BaseT Ethernet/LAN or WAN via a hub. Refer to the table below for the pinouts. A standard (straight, non-cross-over type) Ethernet cable is required, but not supplied.
NOTE: This port should NOT be connected to the UPLINK port of an Ethernet hub.

CEN-CN Indicators
There are six LED indicators located on the front panel of the CEN-CN. For the descriptions of the front panel indicators, refer to the diagram below and the following paragraphs.

P W R N E T | R X D T X D LNK E R R |
This LED (green) illuminates when operating power is supplied to the CEN-CN. Operating power may be supplied either by the external AC power pack (included) that provides 12VDC or supplied by 24VDC via the 4-wire CEN-CN Cresnet system wiring.
NET
This LED (yellow) illuminates when communication with the CEN-CN Cresnet system devices and the CEN-CN is occurring. The connections to these devices are made through the rear panel NET ports.
ETHERNET
These four front panel LEDs are active while the CEN-CN is connected to a LAN or WAN through the rear panel ETHERNET port. The RXD (green) LED illuminates during reception of Ethernet data and TXD (green) illuminates during transmission of Ethernet data. The LNK (yellow) LED illuminates when there are attachments to the Ethernet network and ERR (red) illuminates when an Ethernet protocol error is detected.
