The pin assignment is not as printed on the board. If you look on the back, pin 40 is upper right (where the arrow is)and pin 1 is down left. I measured this with a voltmeter- its like first Gen CMM2. But the print on the board is vice versa.

And Pin40 in the schematic was previously Pin 1. Here the new pinning

and here the old one: same functions, but pin numbers switched
