CWFE(1,2)POCOAX(A,B)[M]
100MBPS ETHERNET OVER COAXIAL CABLE WITH POWER
The ComNet™ CWFE1POCOAX Series transports Ethernet and camera/device
operating power between the remote device and head-end location using
existing 75Ωcoaxial cable. It eliminates the need to have a separate power
source at the remote location and provides operating power for the remote
ComNet media converter and PoE device. Based on the IEEE 802.3af standard
for Power over Ethernet (PoE), the CWFE1POCOAXBM provides up to 15.4 Watts
of operating power to the remote powered device (PD). The CWFE1POCOAXA
transports Ethernet data at rates of 100 Mbps over a distance of 230 meters
(750 feet) over standard 75Ωcoaxial cable. The CWFE(1,2)POCOAXA is used
at the head end and the CWFE1POCOAXBM is used at the remote location,
providing 15 watts of power to the powered device (PD) in the field.
LED indicators are provided for rapidly ascertaining the operating status of the
device. See Figure 9 on Page 5 for LED explanations.
The CWFE1POCOAXA and CWFE2POCOAXA units are designed for shelf, card
cage or stand-alone mounting, making them ideal for those installations were
space is limited. The CWFE1POCOAXBM may also be DIN-rail mounted by the
addition of the ComNet model DINBKT2 Adaptor Plate Kit. See Figures A and B
on Page 6 for mounting instructions.
See Figures 1 – 9 for complete installation details.

INSTALLATION CONSIDERATIONS
This modem is supplied as a Standalone module. Units should be
installed in dry locations protected from extremes of temperature and
humidity.
CAUTION: Take care not to press on any of the LEDs.
WARNING: Unit is to be used with a Listed Class 2 or LPS power supply rated
48 VDC @ 0.85A, 84 VDC @ 1.25 A.
IMPORTANT SAFEGUARDS:
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may
be greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the equipment is
not compromised.
