HELP: BFM Scorp5 and note acceptors / BNV's

Something I am sort of new to, though I have a Red Mummy / NV8.

Been asked to deal with a Mazooma Monopoly game, flashing up a Note error 15, which I have worked out, relates to it's BNV key.

Now I know from my Red machine, the BNV needs to be matched up on the two devices, but I can not for the life of me, work out how this is done on a scorp5.

Mech in question, is a JCM EBA-PB2 (Not upgradeable for the new plastic notes that I do know), so I need help to either install the BNV code (I believe the default code will work in this case), or just disable the mech from the machine all together, although the latter option, I believe reduces the amount the hopper can take (It's on a £70JP - 30p / 50p setup at the mo).

Any ideas?
