Ok, I've tried as many times as possible. I found the 3110 network diagram in the library but I got nothing for the 3110A. The problem is that I have in my hand 2 x 3110A networks but have different parts than the "simple" 3110,so need to be sure If these 3110A I have are really ...3110A. Does anyone here have the original diagram of the 3110A network?
