What is Multi Drop Bus (MDB)?

mul - ti  drop  bus
noun


Multi Drop Bus (MDB) is a communication standard used in vending machines and other automated retail devices. It enables the connection and communication between various components within the machine, such as payment systems, control boards, and peripherals.

How does MDB work?

MDB works by allowing multiple devices within a vending machine or automated retail system to share a single communication bus. This bus facilitates the exchange of data and commands between different components, streamlining the integration of various technologies. MDB uses a multi-drop topology, where devices are connected in parallel to the communication bus. Each device has a unique address, allowing the controller to communicate with individual components as needed. 

MDB helps create a standardized and efficient way for vending machine components to communicate, ensuring compatibility and interoperability among different manufacturers' devices.
