Hi Eric,
I replaced the parallel cable with one of the same length made up from cat5 network cable. Even though the network cable has 10 times less resistance the data on the DATAOUT line is still getting corrupted. I think this is because the signal from the ADC is too weak to send down any significant length of cable. I think I'm going to have to use a buffer of some sort. I was thinking of the 4050B or would a darlington array be better suited?
Thanks,
Salvatore.
