We offer a short explanation on the use of the MDB-USB interface in a “peripheral” role, commonly called slave, for example, to add a mobile or barcode payment system to an existing vending machine.
MDB-USB Interface or MDB Pi Hat
Active MDB Bus
Slave mode can be used to connect payment methods like mobile payment or card readers to your Vending Machine Controller (or VMC for short)
Your Qibixx MDB-USB Interface will connect your VMC to a peripheral and will answer to requests from the VMC only when prompted. It can answer, for example, how many money “it has” on credit. If a payment was made, etc.
Slave mode is also used for Sniffing the MDB Bus. You can learn everything about Sniffing and Monitoring the MDB Bus by clicking here!
