The RT16-10 is a ONE-IN/SIXTEEN-OUT IR switcher which directs an infrared control signal to any one of 16 output ports, any combination of ports, or all 16 as a group. You can control large groups of TV monitors (or any other A/V product) from control locations using Xantech IR Receivers or Smart Pads. Up to 16 devices may be addressed with one RT16-10. Additional RT16-10's can be connected for control of larger numbers of devices, such as TV monitors in a sports bar, by using different IR code groups on each unit. The "I" and "G" output ports can drive LED indicators placed at each controlled device location so that you can see which devices are being addressed at any given time.
