Flat cable problems? The fact that the encoder inputs on the 7I39 do not
work for you means something is wrong either on the 7I39s or the
interconnections to the 7I43
The cable is probably OK. I bought 2 of them and no one works. And the
cable uses 2 completely pairs of wires for encoder 0 and 1. Very unlikely
that all these wires damaged. And some kind of signal was going to 7i43, so
they're can't be broken. The same with 2 7i39s, none of 2 do not work.
Something might be wrong with the power supply from 7i48 to 7i39, but the
Bpower LED is on, and when I connect 7i48 to the same 7i43 with the same
cable - all OK.
Feels like I'm stuck completely, at least till my oscilloscope arrives
(maybe 2 weeks). Also feels like both 7i39 might be damaged - in the worst
case.
Did you verify the bit file md5 checksum?
