Strange effect with Shahe scales
#3
Thanks Yuri for the swift reply.
For the scale that doesn´t work with the board, but the original display, I found out that it transmits three datasets after connection, but then stops. Signal amplitude is 2,5v pp, is this what the board expects?
 
The protocol looks quite simple, is the signal timing , clock frequency critical for your board, maybe this is something  that has changed with this type of scale? I could send you a scope screenshot, if that would help.
