INSTALLATION AND OPERATION MANUAL

FVR22/LV

DUAL INDEPENDENT AM VIDEO RECEIVER WITH
AUTOMATIC GAIN CONTROL AND LOSS OF VIDEO RELAY

The ComNet™ FVR22/LV consists of two independent AM video fiber optic receivers
in one module. It uses two independent multimode fiber optic cables to receive
two separate signals from two transmitters. The module is not a multiplexer. The
module 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 Automatic Gain
Control (AGC). The receiver is compatible with the ComNet FVT11M and the FVT20
dual video transmitter.

The unit incorporates a “Loss of Video” relay for each channel. Upon loss of video
signal or optical fiber break, the normally closed relay opens. See Figure 3 on
Page 3 for Contact Relay settings.

Each receiver incorporates a bi-color (Red/Green) indicating LED for monitoring proper
system operation. See Figure 4 on Page 3 for LED Indicator explanations.

The FVR22/LV 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 4 for mounting instructions.

See Figures 1 – 4 for complete installation details.
