Hi again Dieter

Well, it seems I am mistaken. Today the A-183-1 behaves exactly like you said it should. I have no idea what happened a few days ago...faulty patch cable maybe? 

Anyway, I thought I would reply to the group in case anyone thought there was a problem with A-183's. Mine is fine.

Thanks.
