Please refer to the attached picture.
only W21 is connected
all other cables are disconnected
Again: I was suggesting you try connecting the clock cable (W19). Based on my experience with a similar card, your errors may be a result of W19 being disconnected.
If you don't have the cable, you could try a jumper in place of the clock cable as described in the link I gave a few posts ago. That may allow self-test to succeed.
I no longer have my pattern generator card, so my ability to provide further help is very limited.
