TR-4M is designed for video signal transmission via twisted pair cableThe device adjusts the impedance of a 75Ω coaxial cable to the impedance of a symmetrical cable, ensuring video signal transmission up to 400m (twisted pair cable of 5 categories) and eliminates asymmetric interference
Pay attention to the correct connection of terminals (+) and (-)Reverse connection will cause image interference
