Gene,
Try turning the LED current down. The data sheet listed 10mA in all their
test specs.
The other thing you could try instead of 2 discs offset is creating a
singular slot for the emitter or the detector. Possibly just

Greetings all;
I got the next generation of that board done today and populated it.
This slot type opto device is a Honeywell HOA2001, a 5 terminal device
whose basing is marked on top of each tower for the + terminal and an E for
emitter, or an S for the sensor. The led has a 150 ohm current
the simple thing often forgotten with optos is the pull up on the RX side

Gene,
The datasheet says logic high when the slot is clear, logic low when
interrupted. So sounds like you have no LED. FWIW, 0.8V seems REALLY low
for a LED. Typ about 2x that. Esp running @ 25mA. The max reverse led
voltage is listed as only 3V. Was it ever hooked up backwards? Could have

Honeywell datasheets suck...
The only relatively good picture is the schematic and the view on the left is
from the top and the actual basing they show is from the bottom.
The polarity they show on the top corresponds to the + S for Vcc and + E for
anode/Kathode. At least that is the way I am
