This page details what we know about it.<br /> <br /> Programming occurs over IR, and it looks like the device reports out what it&#039;s displaying<br /> on a single LED on the back as well. The small board with the IR demodulator and red (IR?)<br /> LED on it is labeled &quot;3-750 B.pcb&quot;. The 4-wire connector to it breaks out: two pins<br /> (1 [square pad] and 3) go to the IR demodulator, pin 2 goes to the LED, and pin 4 seems to<br /> be ground.</div>
