INSTALLATION AND OPERATION MANUAL
FVT/FVRXA2C1(M)(S)
2-CHANNEL BI-DIRECTIONAL AUDIO WITH
1 BI-DIRECTIONAL CONTACT CLOSURE
The FVT/FVRXA2C1 series audio multiplexer provides the transmission of
two bi-directional audio signals and one bi-directional optical isolated output
contact closure over one multimode or single mode optical fiber. 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.
Bi-color (Red/Green) LED indicators confirm power and link operating status.
See Figure 6 on Page 3 for LED indicator explanations.
The FVT/FVRXA2C1(M)(S) may be directly plugged into the ComNet Rack (Part
C1) or operated as a standalone module powered by the 9 Volt DC Plug-in
Power Supply also provided with the module. See Figure A on Page 4 for
mounting instructions.
See Figures 1 – 6 for 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 or LPS power supply rated
9-12 VDC @ 1A.
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.
