TR-4P/70 is used for transmitting video signals and delivering power to 4 video transformers TR-1P/70 m1666.htm"> M1666 via twisted pair cables (UTP, FTP, STP). The device adjusts the impedance of 75 ohm coaxial cable to that of twisted pair cable, which enables convenient video transmission over greater distances (up to 400m). Video signal is sent over one pair of a twisted pair cable, the remaining 3 pairs are used for supplying 12V power. TR-4P/70 is powered by 12V DC coming from an external adapter. The device has the LED that indicates proper power connection. It works together with video transformers m1666.htm"> M1666.
