p2 on the breakout board is a steady 1.58 volts in both directions.
p4 is at 1.54 in both dir
so it seems there might be an issue with p2 and p4?
here you can a test of the 25pol cable to make sure that P2 and P4 are connected here.
and for additional testing i think a oszlisocope is needed to check P2,P4 and P6 that there
a pulse stream is created.
