Thanks, I followed Chuck M's advice, and disconnected the BINH, and
the thing words, with 23" as the minimum distance.

I would have to possibly agree. I noticed in your earlier mail you
have suggested putting a 330 ohm resistor between INIT and the handy
board, but not between BINH. I found nothing in the docs that would
suggest that this was a good idea, or required. Might it be a good
idea to put one on BINH also?

I'd have to agree.

separatly ?
Thanks

| Ahh... This sounds right from when I had the same problem. I just forgot about the disconnecting of the BINH. Mainly because it was accidental at the time. Anyways, the point I wish to make is that you have a bad ranging unit. This symptom is (...) (28 years ago, 21-Mar-97, to lugnet.robotics.handyboard)

| Tom, You mentioned that the INIT has the 330ohm. I'm pretty sure it's the BINH and NOT the INIT that should have the 330ohm. Reread Kents documentation. I don't think you would have damaged the unit in this short of time. Like I've mentioned on many (...) (28 years ago, 21-Mar-97, to lugnet.robotics.handyboard)

| Tom, I purchased 2 OEM kits (4 ranging units w/transducers) From this I had 3 bad ranging units. You'll notice a socketed chip on the PCB. I would suspect that this chip is suspect to failure. Anyways, in order to solve your problem, I would suggest (...) (28 years ago, 21-Mar-97, to lugnet.robotics.handyboard)
