DESCRIPTION

The TR-16/SV is designed to video signal transmission via twisted-pair cable. Opto-isolation among input, output and power protects devices against potentials difference. The voltage difference between grounds may occur in the case of a long power line and powering the cameras with different power adapters.

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. It is important to pay attention to linking the adequate terminals: (+) and (-). Reverse connection would cause distortion of image.
