Important about free shipping: 

For our free shipping,that would be sent with slow post mail or slow airmail shipping,normally,that would take around 20 to 60 days to your side. If you need the fast shipping,please select the DHL express delivery shipping,of course,that will have extra shipping cost.

This Interface adapter is designed to convert the vending machine MDB protocol to RS-232 serial protocol. The adapter functions as a slave to a master control system. The master may be any control system that supports RS-232 serial communication, for example a PC.

DESCRIPTION
This adapter is designed to convert the MDB Bill Acceptor (BA) and MDB Coin Changer (CC) protocol to RS-232 serial protocol. The adapter functions as a slave to a master control system. 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-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.

What is MDB-RS232 and RS232-MDB adapter box?

Before order,you should know exactly what is the difference and then you will know what type is the exact products yoou need to order:

MDB-RS232 is used to connect the MDB bill acceptor,coin validator,cashless payment device to computer. then you will design the Software that will run in the PC and work as the master main vending controller. For example,you develop the kiosk information machine. then you need to connect the MDB bill acceptor,coin validator to computer,but you don't know how to connect the MDB interface payment device to computer, because computer only has the RS232 port, no MDB port.then you need to order the MDB-RS232 adapter (MDB-PC Adapter ).

RS232-MDB is used to connect the pc to existing vending machine.then you will need to design the Software that will run in the PC and work as the slave cashless payment device.and then you PC will work as a cashless payment device to vending machine. For example,you want to use the PC to give payment credit to existing vending machine, or if you want to make the internet connection to the vending machine and give credit to vending machine remotely, then you need to order the RS232-MDB adapter (PC-MDB adapter ).

We also provide MDB adapter customized design.Just let me know in detail your project requirement.
