| 14 | * The MDB (Multi-Drop Bus) protocol is used inside a vending machine. MDB |
| 15 | * defines the communication between the main control board (VMC = Vending |
| 16 | * Machine Controller) and peripheral components, e.g. a payment terminal |
| 17 | * or a bill validator. |
| 18 | * |
| 19 | * The VMC acts as bus master and sends a request to one peripheral at a time. |
| 20 | * A peripheral may send data only in response to such a request. |
| 21 | * |
| 22 | * The MDB specification is maintained by the National Automatic Merchandising |
| 23 | * Association (NAMA). As of August 2023, the current version of the MDB |
| 24 | * specification is 4.3. It is available from |
| 25 | * https://namanow.org/nama-releases-mdb-version-4-3/ |
