trouble shoting "Pin 'hm2_5i25.0.7i76.0.0.input-24' does not exist 4977"

.

In the photo above the IDC26 Female Cable #1 Pin is on Left when looking at the connector from facing side.

In 7i92 Manual Schematic, P2 I/O 0..16
are ordered bottom to top 0 to 16. or IDC26 Left to Right.
Schematic indicates P2 IDC26 #1 Pin is on the Bottom or IDC26 = Left is Pin#1.

None of that is relevant, It's as simple as this:

If you have IDC connectors and you align pin1 to pin 1, the cable is correct.
