<p><b>New page</b></p><div>IR Recievivers typically have 3 pins. There are many many different part numbers and I have often not been able to find the spec sheets. Typically the output amp seems to have a load resistor to V+. The power drawn when powered by an ohmmeter is low so the resistance from V+ to ground is high. Finally they do not seem to be greatly harmed by reverse power.<br />
<br />
So to determine pinout:<br />
<br />
Measure the resistance between pairs of pins. Look for a resistance on the order of 20K ohms. The other pin is ground. Power up guessing as to the V+. Put a scope on the presumed signal pin and connect to a scope. Illuminate with a remote. If no response, reverse signal and V+ pins. Test again with scope. Should work now, and you know the pinout.<br />
