The 170 started it all back in 1983. This version of the Xtra Link, Model 172, utilizes the 291-00 IR Receiver which has greatly improved range and interference rejection. The 291-00 receives the IR signals from a hand-held remote, converts them to DC control signals and passes them to the RF/IR Injector where they are mixed with the RF television signal. This combined signal is carried over a coaxial cable. At the other end of this coax the signals are separated at the RF/IR Coupler and the DC control signal is sent to an infrared emitter placed directly on the IR control window of the component you want to control. The Xtra Link 2 system provides full remote control operation of a satellite receiver, cable box or DVD player from a second room. IR control signals from the second room is sent to the main room by using the coaxial cable that carries the TV RF signal from the source equipment located in the main room to the second room. Easy hook-up in minutes without tools. All necessary parts are included. Double the value of your source components by controlling them from another room with the Xtra Link 2 system
