Problems with IR Board

[Mark McLeod]

The logic of the board appears to have it step through the learning sequence even if it isn't really learning anything, as evidenced by the learning sequence continuing even with the error LED blinking. It seems to have to recognize a valid carrier signal and will flash the error light on special protocols it cannot handle.

Anyone else learn anything interesting about their IR board?

I'm pretty sure we received a defective board, but until my sack full of remotes can be tested with another board and we find at least one to be effective can we prove it. I've tried it with remotes from more than a dozen manufacturers, and tried it with and without cycling the power after completing a learning sequence. The LEDs flash during learning, but afterwards not even the error light blinks. Ben from Diversified Systems has been helping and said they'd found a bunch of remotes that wouldn't work. e.g., wrong frequency, cable protocol.

Responses vary from:
--Immediately getting an error light (JVC--tv, Toshiba--dvd, Viewsonic--projector, Infocus--cameras, JQA--projector, Tascam--dvd, Tandberg)

--Uneventful stepping through the learning sequence, but no acknowledgment afterwards (Panasonic universal--vcr/dvd/tv,Pioneer--plasma,Barco--projector, Samsung--dvd/vcr/tv, Sharp universal--hdtv)

--No response whatsoever (old Sherwood--stereo)
