The Model 2172 Dual-head IR Emitter connects to a video hub, 2100A and 2010 in-wall interface, or to a 5500 series IR enabled modulator connected to a video hub. The emitter will repeat the IR remote control signals received at an IR Target that were sent back through the coax cable to two video source components. Each Model 2172 IR emitter has adhesive backing to allow sticking the emitter over the IR sensor on the faceplate of the video source component.
