• 1.Core Function & Protocol Conversion：This converter is primarily designed to connect MDB receivers, bill receivers, and card readers, with a key function of converting the MDB protocol (used in vending machines) to the RS-232 serial protocol. It also specifically converts MDB bill acceptor (BA) and MDB changer protocols to RS-232, serving as a slave device for the main control system—compatible with any master device that supports RS-232 serial communication, such as a PC.
• 2.Wide Compatibility & Flexible Connection：It offers strong compatibility, supporting not only the RS232 port of computers but also Android motherboards or other motherboards equipped with RS232 or USB ports. For devices with only a USB port, an additional USB-to-RS232 transfer case can be used to create a virtual COM port on PCs or Android boards, ensuring flexible connection in various scenarios.
• 3.Rich Interface Support & Control Capability：It supports a range of interfaces including MDB, cash interfaces (10H and 60H), and USD interface (40H). Additionally, it enables PCs to control multiple devices such as acceptors, change dispensers, smart card readers, magnetic card readers, credit card readers, bill acceptors, and bill verifiers, meeting diverse operational needs.
• 4.Compliance, Expandability & Accessory Inclusion：The converter fully complies with all NAMA MDB specifications, ensuring compatibility with any vending equipment that adheres to MDB standards. A single unit can connect up to 8 MDB-compatible devices, offering strong expandability. It also comes with necessary accessories like cables, a user guide, and a user agreement for convenient setup.
• 5.System Role & Adaptability：Functioning as a slave device of the main control system, it seamlessly adapts to any master control system that supports RS-232 serial communication (such as a PC). This design ensures it integrates smoothly into various control setups, making it a reliable bridge between MDB devices and the main control system.
