Building your own infrared repeater gives you a way to control audio visual equipment without having ugly receivers in view. The infrared repeater takes the infrared signal from a remote and repeats it at another location. The design is simple. Wiring is required, but most of the project is plug and play.

Instructions

  1. 1

    Find the infrared receiver port on the audio visual equipment. It will be a circular port, usually to the side of the information display on the unit. Clean it with glass cleaner and paper towels to ensure a good bind from the adhesive of an infrared blaster. Peel the sticker off the infrared blaster adhesive and affix it firmly to the port. Repeat this process for every component that you want to control via the infrared repeater.

  2. 2

    Place the infrared receiver at a point where it has a clear view of where you will be using the remote. The receiver is visually unobtrusive. The rear of the receiver will have labelled wire clamps. S is for the status wire, T is for the transmission, G is for the ground and the V is for voltage. Cut off four lengths of wire that can reach from the infrared receiver to the connection hub, which will be hidden in one of the cabinets.

  3. 3

    Strip 1/4 inch from the ends of each of the four wires. Slide a wire into the voltage clamp on the receiver and the other end into the voltage output on the hub. Slide a wire into the G clamp next to the V clamp on the receiver and slide the other end of that wire into the ground clamp on the hub. Slide a wire into the S clamp and into the status clamp on the hub. Slide a wire into the T clamp on the receiver and into the IR IN clamp on the hub.

  4. 4

    Plug the infrared blaster plugs into the free emitter ports on the hub. The plugs will slide in by hand. Plug the power plug into the hub from the power cord. Turn on the audio visual equipment that you want to control and then control it via remote. The infrared repeater will automatically pick up the signal and repeat it.
