STEPS For a full schematic, click here. 1 Download the IR-receiver data sheet from www.simerec.com. 2 Snip the receptacle end off an extension cord. Bend two scrap wires into a “Y” and connect that to a wire from the cord. Connect the two arms of the “Y” to the socket and wall adapter that go inside the Zapper. Connect the cord’s other wire to the adapter, which provides five volts for the IR receiver and relays. 3 Follow the schematic to assemble the IR-receiver circuit, switches and relays. 4 Fit all the parts into the electrical boxes. 5 Plug the box’s cord into the wall. To program, point the remote at the box and hit the button you want to use, following the sequence in the data sheet. 6 Plug appliances into the outlets. Press the first programmed button to turn the first outlet on, and again to turn it off. Repeat with the second button and outlet. To operate the appliance, leave its power switch on.
