FVT/FVR1021(M)(S)1
10-BIT DIGITAL VIDEO WITH RETURN DATA
The FVT/FVR1021 series video transmitter/receiver and data transceiver
supports the simultaneous transmission of short-haul quality 10-bit digital
video and return data over one multimode or single mode optical fiber. This
module is universally compatible with major CCTV camera manufacturers and
supports RS232 and RS422 data interfaces as well as up-the-coax data.
Bi-color (Red/Green) LED indicators are provided for rapidly ascertaining
equipment operating status. These units are interchangeable between stand-
alone or card mount configurations. See Figure A on Page 5 for mounting
instructions.
Figures 4 through 6 on Page 3 illustrates the specific data connections for
RS232, RS422, Manchester and Bi-Phase data transmission.
Figure 7 on Page 4 describes the LED indicators for each light on the unit.

MECHANICAL INSTALLATION INSTRUCTIONS
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.

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.
