Williams Chinese NTX G1 board help

[Countryfreak]

Hi,all! I have acquired a Life of Luxury that has the Chinese Ntx G1 board.Bill acceptor was working but lent it to a friend to try on their machine and in trying a few, we mixed them up!I have tried another working BV with communication board on side of carrier and a few others that will cycle but can not get it to take bills at all.Being new to these Chinese  boards,my question is,do I have to do a clear ram when BV is changed? If so,will it be same procedure as other LOL set up?This one doesn't have the communication board behind cash box, and I can't for the life of me remember if the BV one that came with it had one or not. I figured how to go into menu,but,I think other than doing a ram clear to start fresh,there isn't much I could do since it asks for a password. Which I don't have. I appreciate any assistance in advance 😁

If you are using a WBA you probably need one programmed with the Pulse protocol, ID044 I think
