I have moved over from the old site and unfortunately I am still having trouble with my bill val com error. I have done everything that was suggested to me in the old site. But before I go and ram clear a working machine to find out if the board has a problem please could you help me with a step -by step guide on how to ram clear properly. And once I have ram cleared what are the settings that have to be reprogrammed into the machine. are they all under the setup menu or are there other settings else ware.

Kim, the link on this site for the clear procedure is below, also read DJH's post after Ozzy's.

I should mention that the Ram clear described on that message is for the older RAM clear cards.  The newer cards with 1350 or later automatically clear NVRAM and EEPROM, the only thing that needs to be decided is the monitor timing.  If you have an LCD display, it doesn't matter what you choose, if you have a CRT, you should choose the Legacy monitor.

I have done the ram clear procedure and it is still giving me bill val com error, I have changed the whole bill acceptor unit with board and all from a working machine and I am still getting the same error. I have also changed the wire harness from the back board to the bill acceptor and still nothing. I do not know what else to do Please could someone advice me

if you have another nxt board, can you try that on your non-working machine.  You could have a bad serial port in the nxt board.  You will probably have to perform a clear when you try the other board on the non-working machine.
