MDB

Let's make it simple: MDB stands for Multi-Drop Bus. It's a standard way for different parts of a vending machine to talk to each other. Think of it as a common language that all the components understand.

Key Points About MDB:

  1. Standard Communication MDB ensures that parts like coin acceptors, card readers, and the vending machine controller can communicate smoothly.

  2. Single Cable for Power and Data MDB cables carry both power and data, making setup easier with fewer cables.

  3. Master-Slave Setup The vending machine controller (master) talks to the other devices (slaves) to get information and send commands.

  4. Polling Mechanism The controller checks each device, in turn, to see if there's any new data, like coins inserted or cards swiped.

Why MDB is Important:

  • Compatibility: Different parts from various manufacturers can work together.

  • Reliability: Provides a dependable way for devices to exchange data.

  • Simplicity: Fewer cables and easier installation.

The MDB protocol is commonly used for managing payments, selecting products, and integrating various payment options.
