INSTALLATION AND OPERATION MANUAL
FTA/FRA2C1(M,S)1 and FXA2C1(M,S)1
2 AUDIO CHANNELS + 1 CONTACT CLOSURE
The ComNet™FTA/FRA2C1 Series audio multiplexer provides the transmission of two
audio signals and one contact closure over one multimode or single mode optical
fiber. A bidirectional model, FXA2C1(M,S)1, is also available. The modules use 24-bit
96kHz sample rate digital encoding for superior transmission of balanced line-level
audio. Plug-and-play design ensures ease of installation and no electrical or optical
adjustments are required.
These extenders are designed for long-term, reliable operation in harsh industrial
environments, and a fault-specific LED indicator is provided for rapidly ascertaining
the operating status of the extender and the link. See Figure 9 on Page 5for an
explanation of LED indicators.
Packaged in the exclusive ComNet ComFit housing, these units may be either wall or
rack mounted. See Figure A on Page 6for mounting instructions.
See Figures 1 – 9for complete installation details.

INSTALLATION CONSIDERATIONS
This fiber-optic link is supplied as a Standalone/Rack module. Units should
be installed in dry locations protected from extremes of temperature and
humidity.
C1-US, C1-EU, C1-AU OR C1-CH CARD CAGE RACKS
CAUTION: Although the units are hot-swappable and may be installed
without turning power off to the rack, ComNet recommends that the
power supply be turned off and that the rack power supply is disconnected
from any power source. Note: Remove electrical connector before
installing in card cage rack.
1. Make sure that the card is oriented right side up, and slide it into the card
guides in the rack until the edge connector at the back of the card seats in
the corresponding slot in the rack’s connector panel. Seating may require
thumb pressure on the top and bottom of the card’s front panel.
CAUTION: Take care not to press on any of the LEDs.
2. Tighten the two thumb screws on the card until the front panel of the
card is seated against the front of the rack.
WARNING: Unit is to be used with a Listed Class 2 power supply.
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.
