Nayax MDB Codes vs. PA Codes

MDB code = the numeric selection ID from the vending controller. PA code = the button or slot the customer uses, such as A3 or B12. If you do not have a code table, map them by making test vends and matching the MDB code to the selection you pressed.

MDB code

The vending controller reports a numeric code for the internal row or channel used during the vend.

PA code

The PA code is the customer-facing selection. It can be alphanumeric even when the MDB code is numeric.

If you do not have a code table

Vend one selection at a time, check the MDB code shown in Nayax Last Sales, and pair it with the button or slot you used.
