EX560 Nitek Unshielded Twisted Pair (UTP) transmission from 500 feet (304 m) to 6,000 feet

The EX560 is a complete twisted pair video system made up of a TR560 receiver unit and a TT560 transmitter unit. The system is designed to operate over Category 2 or better twisted pair cable. It works well over existing communication, computer network spare pairs, or new cable installations. A highly balanced transmitter output assures that the system will not interfere with other network equipment. Advanced receiver and transmitter electronics provide optimum video quality and complete immunity from ground loop, hum and noise. Both the transmitter and receiver provide adjustment for gain and frequency compensation allowing the system to be “fine-tuned” for the cable. These unique adjustments provide optimum performance over the entire operating range of the system and allow cable lengths to be estimated with a wide safety margin. The receiver and transmitter units each require 12-24 VAC/VDC power. In multiple receiver and/or transmitter applications a common supply can be used for the system.
