We have a Cummins Annunicator and Echelon iLON600 router. We spend several days trying to figure out why we couldn't get the iLON600 to communicate with the Annunicator via FT-10.
It turns out that if we used twisted pair wire longer then 1ft it wouldn't work. Once we went back to 1ft, it communicated without any problems.
Does this appear to be a termination problem. We are thinking that the resistance of the wire longer then 1ft changed the termination value of the FT-10 bus.
Has anyone ever seen something like this?
