Since you have a scope, check the signal that's getting to your IR LED on the beacon to make sure the beacon is assembled correctly.
The detector should be able to see the beacon at distances at least 20 or 30 feet away.
Also: the detector will only turn on for either 1ms or 2ms (depending on which beacon it's seeing) every 10ms. Did you zoom in enough on your scope to see that?
