CEN-C-TX-F and CEN-C-RX-F
Ethernet over Fiber Transmitter and Receiver
Installation Guide
Description
The Crestron
®
CEN-C-TX-F and CEN-C-RX-F deliver straightforward, cost-effective
Ethernet signal extension for home and commercial applications. Without any special
setup or configuration, the CEN-C-TX-F and CEN-C-RX-F afford long-distance,
high-speed communications over a single fiber strand for control systems and other
networks.
Installation
Mount the CEN-C-TX-F/CEN-C-RX-F onto a flat surface or onto a rack rail.
Mounting onto a Flat Surface
Using four drywall screws (not included), mount the device onto a flat surface such as a
wall or a ceiling. Mounting of the device on a wall is shown below.

Rack Mounting
The CEN-C-TX-F/CEN-C-RX-F mounts onto the front or rear rail of a rack.
To mount the CEN-C-TX-F/CEN-C-RX-F to a rack:
1. Position either the left or right mounting flange of the device so that its holes align
with the holes in the rack.
2. Secure the device to the rack using two rack mounting screws (not included).
Mounting of the right flange of the device is shown below.
Mounting onto a Rack Rail
The following sections provide information about each of the connections that can be
made to the CEN-C-TX-F and CEN-C-RX-F.
Connecting the Ground
Connect the chassis ground lug to earth ground (building steel).
Connecting the LAN PoE Port
Depending on the equipment purchased, connect the LAN PoE port to a Crestron PoE
injector, a Crestron PoE switch, or a third-party 802.3af compliant power source:
• For information about the Crestron PoE injector, refer to the PWE-4803RU PoE
Injector Installation Guide (Doc. 6712), which is available from the Crestron website
(www.crestron.com/manuals).
• For information about Crestron PoE switches, refer to the CEN-SW-POE-5 Switch
DO Guide (Doc. 7736), the CEN-SWPOE-16 Switch DO Guide (Doc. 7941A), or the
CEN-SWPOE-16 Switch Supplemental Guide (Doc. 7408) as applicable.
• For information about a third-party 802.3af power source, refer to the
documentation supplied with the device.
Connecting the MMF/SC Fiber Port
Using a multimode fiber optic cable with SC connectors (such as the Crestron CresFiber
®
8G cable), connect one end of the cable to the MMF/SC connector on the CEN-C-TX-F
and the other end of the cable to the MMF/SC connector on the CEN-C-RX-F.
Connections
Connect the CEN-C-TX-F and CEN-C-RX-F as shown below.
