Houston...we had a problem.
I have a WMS BB2 test set-up running an MEI SC6607 bill validator.
It's been working for years - without any problems.
I use the set-up to test BB2 validator heads and Cashflow boxes.
All of a sudden, the green LEDs on the bezel stayed on continuosly....even with the door closed.

When I go into Diagnostics, and run a CRC check, it will time-out, not give any checksum numbers, and cannot find the acceptor, nor pull in any bills.

But when I get out of Diagnostics, and back into game mode, it pulls in bills, they get stacked inside the box, but zero credits get registered.
So I put in the known good head...no go.

I throw in the known good cashbox....no go.

You know what it was?
The Interface card.

I swapped the interface card and everything works perfectly.

but...get this....I pulled it from an IGT i-Game BV unit?
A wow moment...I never knew it doesn't matter what machine you use an interface card from?
