FVR21

DUAL INDEPENDENT AM VIDEO RECEIVER
WITH MANUAL GAIN CONTROL

The ComNet™ FVR21 dual video receiver detects two independent AM video signals
in one module on two independent multimode fiber optic cables. The module is
not a multiplexer. The module is ideal for CCTV installations and the rack mount
version can be used to double the fixed video capacity of the C1 rack for up to 28
independent video channels per card cage. The modules utilize Manual Gain Control.

The receiver is compatible with the ComNet FVT11M single video transmitter and the
FVT20 dual video transmitter.

Each receiver incorporates a bi-color (Red/Green) indicating LED for monitoring proper
system operation. See Figure 3 on Page 2 for LED Indicator explanations.

The FVR21 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. See Figure A on Page 3 for mounting instructions.

See Figures 1 – 3 for complete installation details.
