I believe I have killed the optic board on my Vortex.
When I meter the input voltage, it's fine (4.94vdc), but when I meter the outputs from the sensors, I also get 4.94, and it doesn't change when the beam is broken. I DID drop the thing a few days ago. Is it possible that the impact could have damaged the sensors and shorted them out? (BTW, no traces broken, etc.) I wouldn't even bother to ask except it seems like I can't currently get a replacement board...
