INSTALLATION AND OPERATION MANUAL
CWFE(1,2)COAX[M]
100MBPS ETHERNET-OVER-COAX
SINGLE / DUAL CHANNEL
The ComNet™CWFE1COAX[M] and CNFE2COAX support high-speed Ethernet
transmission over standard 75 Ωcoaxial cable circuits, at data rates of
100Mbps, and transmission distances of up to 305 meters (1000 feet).
The CWFE1COAXM is a small sized unit and the CWFE2COAX contains two
independent channels in a single standard-sized enclosure (ComFit). These
modems are the perfect solution for upgrading an existing coaxial cable plant
for use with Ethernet, when compared to the significant costs and nuisance of
installing new network cabling.
User-configurable master/remote selection is included for unparalleled
versatility. See Figure 10 on Page 5 for Switch settings.
LED indicators are provided for rapidly ascertaining the operating status of the
device. See Figure 9 on Page 5 for LED explanations.
These units are designed for shelf, card cage or stand-alone mounting, making
them ideal for those installations were space is limited. The CWFE1COAXM
and CWFE2COAX 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 – 10 for complete installation details.

MECHANICAL INSTALLATION INSTRUCTIONS

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
9-24 VDC, 12-24 VAC @ 120 mA.
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.
