Familiarization with the VCX-7401

The VCX-7401 Video Encoder accepts one BNC video in, one BNC Video Out 
and one data sub-channel. The encoder has a programmable reset, which prompts 
the re-initiation of the video stream. The decoder also has a programmable reset 
command, tied to errors in the incoming video stream, as well as a reboot 
command.
