the comNet™ FVR21/LV 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 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 FVR21/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.
