The interface controls MM3 by onboard IR-LEDs or by the original keypad transmitter which is the default because it has more powerful IR-LEDs. 12v Power to the interface is supplied from a voltage convertor on the Arduino shield using a 3.5mm jack-cable into the existing external power socket, and control by a 10way cable again into the existing socket. A voltage convertor is used so the Arduino can be powered just by the USB cable.
