View our MDB-RS232 BOX ,That is testing with different brands bill validator and coin acceptors video:
This Interface adapter is designed to convert the vending machine MDB protocol to RS-232 serial protocol. The adapter box is working with PC and functions as a MDB Master to control the MDB payment devices, for example, MDB coin acceptor, bill acceptor, cashless payment devices. The master may be any control system that supports RS-232 serial communication, for example a PC.
PC Test Software:
DESCRIPTION
This adapter is designed to convert the MDB Bill Acceptor BA and MDB Coin Changer CC protocol to RS-232 serial protocol. The master may be any control system that supports RS-232 serial communication, for example a PC.
OPERATION:
The master and slave communication is based on master requests and slave replies. The master sends a status request or command to the IU and IU answers by sending its current status. The IU’s typical response to the Master’s request polling consists of a header and data bytes. If there is no BA or CC activity, the status is one byte, the header only. When the IU receives data from the BA or CC, it sends a header followed by data bytes in the response to master’s status request. The master must always poll query the IU. If the IU does not receive a query from the master in the predefined time slot or IU does not recognize master messages 10 times in row, it will inhibit the BA and CC acceptance. At power up, acceptance of the BA and CC is inhibited.
What is MDB and Why do I need the MDB-RS232 ?
MDB stands for Multi-Drop Bus and is a protocol developed by vending machine industry. 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. The MDB-RS232 is a microprocessor controlled hardware interface with embedded firmware that converts the MDB protocol to an RS232 protocol and also performs the necessary voltage conversion. The MDB-RS232 also relieves the Polling requirements thereby allowing the same PC to perform other tasks.
The MDB-RS232 is necessary to interface the industry standard MDB Vending machine protocol to a standard PC because:
The MDB uses 11 Bits and a nine 9 bit byte.
The polling requirements for the various MDB devices are excessive 20-200 ms.
A non-dedicated PC can not meet the polling requirements.
The MDB-RS232 takes care of the polling requirements and generates an interrupt on the serial port of the PC.
This methods allows the PC to perform normal operations and respond to interrupt driven comm events in the UART buffer.
All data from an MDB device is available to the PC.
Additionally, all commands can be sent to the MDB device from the PC ie. dispense, write to smart card etc…
The MDB-RS232 interfaces any MDB vending device 6-pin molex/5pin MTA to the PC via the serial port DB-9. Future support may include Universal Serial Bus. The MDB-RS232 protocol is compatible with standard RS-232 Protocol.
Coin Acceptors/Dispensers and Foreign Currency:
Any MDB compliant device may be interfaced to a PC. This now makes it possible to accept and dispense any coin types including foreign currency and Euro Dollar when available.
Smart Card Reader
MDB compliant smart card readers can now be accessed.
