Cooter Posted November 17 Share Posted November 17 I installed a Nayax VPOS Touch Reader on my National 673. When I change the machine setting to 'MDB Card Reader', it throws an error 'CARD.F.COMM'. The reader will charge $1.00, but not credit the machine. Bill validator and Coin Mech still work fine. The reader is the first device connected to the main board, with validator and coin connected to the splitter. Nayax support told me this is a machine communication issue, and to contact Crane, but that is proving to be difficult to get an answer. Link to comment Share on other sites More sharing options...
AZVendor Posted November 17 Share Posted November 17 You probably need the latest eprom. Link to comment Share on other sites More sharing options...
Cooter Posted Saturday at 08:58 PM Author Share Posted Saturday at 08:58 PM Installed the latest eeprom, and still the same issue. Crane support says it could be a control board issue. Kinda strange that the bill val and coin mech work fine. Link to comment Share on other sites More sharing options...
Cooter Posted 22 minutes ago Author Share Posted 22 minutes ago Got it working. I just had to reset the parameters and reload the machine configuration on the Nayax, and the error went away. Also had to enable pre-selection option for the purchase to go through. The first Nayax rep and a Crane tech told me it was a control board problem. Turns out it was just a configuration error on the card reader. Link to comment Share on other sites More sharing options...
