DIGITALLY ENCODED VIDEO WITH BI-DIRECTIONAL DATA
AND SIMPLEX CONTACT CLOSURE

The ComNet™ FV T1D1[/M] video transmitter, along with the FVR1D1 and FVR2D2,
supports the transmission of digital video transmission and bi-directional RS422 or
2- or 4-wire RS485 data channel over multimode or single mode optical fiber(s).
When the unit is operated in the RS422 2-wire data mode, a simplex contact closure
channel is available. This module is universally compatible with major CCTV camera
manufacturers. Plug-and-play design ensures ease of installation and no electrical or
optical adjustments are ever required.

Each unit incorporates a bi-color (Red/Green) indicating LED for monitoring proper
system operation. See Figure 9 on Page 6 for LED Indicator explanations.

The ComFit units in this series may be directly plugged into the ComNet Rack
(Part C1) or may be either wall-mounted, rack-mounted, or DIN-rail mounted by
the addition of ComNet model DINBKT1 adaptor plate. The small-size FVT1D1/M
transmitters are ideal for locations where space is at a premium and are surface mount
only. See Figure A on Page 8 for mounting instructions.

See Figures 1 – 12 for complete installation details.

MECHANICAL INSTALLATION INSTRUCTIONS

INSTALLATION CONSIDERATIONS

The ComFit fiber optic links in this series are supplied as a Standalone/
Rack module. The FVT1D1/M is supplies as a Standalone/Surface-mount
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.

.156 [3.96 mm]

.313 [7.95 mm]

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.
