Transmitter/Receiver Need 711N

OUR PART #  712N

The 711N and 712N are a twisted pair transmitter and receiver for composite video and unbalanced stereo audio signals. The 711N transmitter converts composite video and stereo audio to a twisted pair signal and the 712N receiver converts the twisted pair signal back into composite video and stereo audio signals.
