What You Will Learn
Configuration
The MDB-USB Interface will link your VMC to a peripheral device, responding to requests from the VMC only when prompted.
For instance, it can report how much credit is available or confirm if a payment has been made.
Peripheral
Moreover, peripheral mode is essential for sniffing the bus.
This feature allows you to monitor and analyze all data passing through the bus, providing valuable insights into the transactions and operations of your vending machine.
Connection
The bus connects from the machine to our MDB-USB Interface.
The interface is then connected to the VMC, acting as a bridge for the peripheral device.
Communication
Use any of our VEMIO products as a controller that connects to the interface to manage the communication and process the payment.
What You Will Need

MDB-USB Interface (Standard or Ultra) or MDB Pi Hat;

An active bus;

VEMIO (VEMIO-1 or VEMIO-2).
