PFM800B-4K is intended for sending a video signal via a computer cable
The device adapts the 75Ω impedance of the coaxial cable to the impedance of the symmetrical cable, ensuring video signal transmission at a distance of up to 400m (category 5 computer twisted pair) and eliminating asymmetric interference
It is necessary to pay attention to the correct connection of the (+) and (-) terminals.
Reverse connection causes video distortion
