Description of the device from AllElectronics:
Our best guess is this is an infrared receiver/ transmitter for use with televisions or other remote-controlled equipment. Made for OnCommand™, it consists of a small black box, 2″ x 1.95″ x 0.6″ with a dark-red plastic IR window on one side. Inside is a small pc board with four clear LEDs and a module that looks like an IR receiver. There is a 3.5mm phone jack and a 6′ 6-conductor phone cord with a modular phone plug.

This circuit can be used with one minor modification to make a serial IR receiver for use with LIRC. http://lnx.manoweb.com/lirc/?partType=section&partName=circuit Connect the following: White Wire to DCD (Pin 1), Red Wire to RTS (Pin 7), Blue Wire – GND (Pin 5) The only modification you must perform is to add a pullup resistor between the output pin on the IR transmittor (connected to the white wire) and “In” on the 78l05 (the pin on the main IC closest to the red wire). Seems to work great.
Note: I (Tim) have personally used these instructions and can confirm that they work. With the white/data wire tied to DCD as above, make sure to select “DCD Device” rather than “Rx Device” in the (Win)LIRC serial receiver settings.

Just received this module and started playing around with it. This is what i figured out for the wiring. Yellow and Blue- ground, Red and Green- positive(around 9-12VDC), White- IR out, Black- IR in, 3.5mm jack- External IR emitter If you jumper the white and black together whatever is received from the ir receiver is transmitted out the four IR emitters on the board.(IR amplifier)Or plug in an IR emitter to the jack and controll hard to reach equipment.I have thought up many ways of using these modules.
