This versatile MDB-RS232 gateway simplifies connecting MDB peripherals (bill acceptors, coin validators, cashless payment devices) to RS232-based VMC controllers, such as PCs, Android boards, PLCs, or Raspberry Pi. It provides a robust payment interface solution for vending systems.
How does the MDB-RS232 interface function?
The converter transmits all data from MDB payment devices directly to the VMC board. Conversely, the VMC can issue commands (e.g., Dispense, Enable, Disable) to the MDB peripherals through the converter. Essentially, the MDB-RS232 bridges MDB-only peripherals with RS232-only VMC controllers.
Vending machines selling regulated goods such as cigarettes or alcoholic beverages face differing age restrictions across countries. To operate legally, these systems must authenticate the purchaser's age before dispensing. Consequently, incorporating an MDB age verification interface is a fundamental development requirement. Developers should also consider reserving necessary interfaces to accommodate future compliance upgrades or feature additions.
