Multi-drop bus to RS-232 or USB PC interface ( MDB-RS232 ) Working with bill acceptor,coin validator, card reader,cashless defvice, for vending machine,kiosk machine,kiosk information machine Special MDB2PC SDK sets: (PC development software code including ) In this order ,that including: 1. Two pcs MDB2PCS adapter box 2. Two pcs RS232 to USB adapter 3. PC software SDK source code to make your development more easier in the below picture,that is one set picture ,in our package would include two sets for you The vending machine standard NAMA Multi-Drop Bus (MDB) may now be interfaced to a PC using the MDB-RS232. The MDB-RS232 allows Coin Acceptance, Change Dispensing, smart card reader, magnetic swipe, credit card reader,bill acceptor and bill validation all controlled by the PC.Conforms to all NAMA MDB specification and is compatible with any MDB compliant vending device. Hardware interface comes with cables,user's guide and user's protocal. Up to eight (8) MDB compliant devices may be attached to a single MDB-RS232. The programming interface is user-friendly. ( For Pulse type Coin validator and bill acceptor to PC, please check: PULSE-PC adapter ) This Interface Unit (IU) is designed to convert the MDB Bill Acceptor (BA) and MDB Coin Changer (CC) protocol to RS-232 serial protocol. The IU 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 Interface Unit (IU) is designed to convert the MDB Bill Acceptor (BA) and MDB Coin Changer (CC) protocol to RS-232 serial protocol. The IU 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. SPECIFICATION: Communication format: Baud rate Start bit Data bits Parity Stop bit 9600 BPS 1 8 NO 1 Timing Specification: Inter-byte (max) Response (max) Master polling times every Time IU waits for the Master’s poll before inhibiting acceptance of the BA and CC (max) 1 ms 50 ms 150 – 300 ms 3 second Hardware Specification. Power Cable Dimensions Weight Min 20 VDC Nominal 24...34 VDC (or 24...30VAC) Max 39 VDC Consumes an idle current < 0.05A 0.5A for 1 sec. when accepting bills Standard computer serial cable Standard MDB cable approx. 100 x 50 x 30 mm approx. 115 g Optional Parts: Power Supply For MDB RS232 adapter board ( 24VDC 3A) References MDB Protocal The MDB Spy program is implemented according to the MDB specifications as stated in : NAMA MDB / ICP protocol specification Supported by the NAMA, EVA and EVMMA organizations.
