![]() This methods allows the PC to perform normal operations and respond to interrupt driven comm events in the UART buffer.The EasyMDB takes care of the polling requirements and generates an interrupt on the serial port of the PC.A non-dedicated PC can not meet the polling requirements.The polling requirements for the various MDB devices are excessive (20-200 ms).The MDB uses 11 Bits and a nine (9) bit byte.The EasyMDB is necessary to interface the industry standard MDB Vending machine protocol to a standard PC because: The EasyMDB also relieves the Polling requirements thereby allowing the same PC to perform other tasks. The EasyMDB is a microprocessor controlled hardware interface with embedded firmware that converts the MDB protocol to an RS232 and USB protocol and also performs the necessary voltage conversion. The “Multi-drop Bus” (MDB) protocol is not compatible with the standard RS-232 PC protocol and therefore a hardware and software interface is necessary. MDB stands for “Multi-Drop Bus” and is a protocol developed by vending machine industry. Is a Computer Peripheral for interfacing vending machine protocol used by various devices including: Dollar Bill Validators, Coin AcceptorsĬompatible with any brand and manufacturer MDB compliant ![]() MDB Interface that allows the communications throw RS232 and USB protocol ![]() Habilitar y deshabitar dispositivo de cobro. ![]()
