PFM809-4MP is designed for sending a video signal through a computer cable.
The device adapts the 75 Ω impedance of the coaxial cable to the impedance of the symmetrical cable, ensuring video signal transmission up to 250m @ 720p / 150m @ 1080p (category 5e 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
