The TR-4MET is designed to video signal transmission via twisted-pair cable. The device adapts the impedance of coaxial cable 75Ω to the impedance of symmetrical line, ensuring transmission of video signal up to 400m (twisted-pair cable category 5) and eliminates asymmetric interferences. The device has also a DATA connector, which allows to data transmission (e.g. RS-485) via one pair of the twisted-pair cable (connected to the No.1 and No.2 pins of the RJ-45 socket).
Two devices must be used to build a complete channel for signal transmission. It is important to pay attention to linking the adequate terminals: (+) and (-). Reverse connection would cause distortion of image.
