How to tell if a vending machine is MDB

MDB in Vending Machines

To determine if your vending machine accepts MDB (Multi-Drop Bus) protocol, you can follow these steps:

  1. Check the Manufacturer’s Specifications: Look up the specifications of your vending machine provided by the manufacturer. This includes manuals or any online documentation. This information should indicate whether the machine is MDB compatible.
  2. Inspect the Bill Validator and Coin Changer: MDB-compatible vending machines typically have MDB interfaces for both the bill validator and coin changer. If you can access these components, look for labels, markings or connectors indicating MDB compatibility.
  3. Look for MDB Labels: Often, vending machines that support MDB will have labels or stickers indicating this compatibility somewhere on the machine’s exterior. Check around the coin slot or bill acceptor area for any such labels.
  4. Consult a Technician: If you’re uncertain, you may want to consult with a vending machine technician. They can inspect the machine and confirm whether it supports MDB.
  5. Examine the Interface: MDB interfaces usually have a specific connector type. If you can access the internal components of the vending machine, look for connectors with multiple pins arranged in a specific pattern, which is characteristic of MDB connections. Here is how a typical MDB connector looks like: https://www.cable-tester.com/mdb-connector-pin-out/
  6. Contact the Manufacturer: If all else fails, contacting the manufacturer directly and providing them with the model and serial number of your vending machine is a good way to get accurate information about its compatibility with MDB.

 

Remember that MDB compatibility is crucial if you plan to integrate your vending machine with other devices, such as card readers or telemetry systems, that use this protocol for communication.
