1 Shanghai Wafer Microelectronics Co., Ltd. 23E,Liang Feng Building,NO.8,DongFang Road,Shanghai,China Tel.: (0086) Fax: (0086) MDB Coin Changer and MDB Bill Acceptor to RS 232 Interface Model: MDB RS232 (New Version box type) SPECIFICATIONS Communication format. Baud rate 9600BPS Start bit 1 Data bits 8 Parity NO Stop bit 1 Hardware Specification. Power Cable Dimensions Weight Install the MDB RS232 Min 20 VDC Nominal VDC (or VAC) Consumes an idle current < 0.05A 0.5A for 1 sec. when accepting bills Standard computer serial cable approx. 80 x 50 mm approx. 100 g (0.2 lb.) On the MDB RS232 box,there are three type connectors: Page 1 of 7

2 (1) RS232 connector to Computer COM port (2) Power connector for AC/DC power supply (3) MDB connector to bill acceptor,coin validator or card reader Installation is relatively simple; there are only three connections that must be made for full functioning of the device. There are connectors on the MDB adapter box. One cable plugs into a 24VDC power supply. The 6 pin Molex connects to the MDB devices. The final connector is a DB 9 and connects into the back of the computer. There should be an open port on the back of the computer labeled SERIAL2 or COM2. If you only has the USB port on your computer,then would be easy for you to order a RS232/USB adapter. After connected the device,and then Apply power on with DC24V. Check for Power Status LED on the box (RED led) indicating power is OK. If the MDB device is properly connected and working properly,then the MDB Status LED should start to flash. On the MDB RS232 box also has another PC Communication LED,that would be flashing if has any data sendt from MDB RS232 box to PC. Software The MDB RS232 sends information generated by the MDB device directly to the PC via RS 232 serial communication. There is no need to poll each MDB device. This is done by the MDB RS232. By default the MDB RS232 will poll all known MDB devices. The MDB RS232 then sends data to the PC if there is activity. The information sent to the PC is send as bytes in hexadecimal. The first byte sent is the device ID. For example 30 XX means that a bill validator has sent information. Whereas 08 XX means that a coin mechanism has sent data. Consult the MDB V3.0 or MDB V4.0 command specification for commands specific to your MDB device. MDB RS232 Software Communication Receive Use an interrupt driven comm event on the appropriate com port. Settings are None. Set the receive threshold to 1. Empty the contents of the receive buffer as soon as there is at least one character ready. Transmit Use an interrupt driven comm event on the appropriate port. Settings are None. Set the transmit threshold to 1. Send the address of the device followed by the command parameters. Handshaking When the PC has data to send to an MDB device the following is required for sending this data: Send DTR high (DTR.Enabled=TRUE) On Change in CTS line (generated by the MDB RS232) set output buffer=string to be transmitted Place contents of string in output buffer and transmit Set DTR low after transmitting entire string Page 2 of 7

3 MDB OPERATION NOTES BILL VALIDATOR Bills Accepted (Byte 1) 1yyyxxxx yyy = Bill Routing 000 = Bill Stacked 001 = Escrow Request 010 = Bill Returned 011 = Not Used 100 = Disabled Bill Rejected xxxx = Bill Type The bill types are: Type 0 = $1 Type 2 = $5 Type 4 = $20 Type 1 = $2 Type 3 = $10 The software should have all of the bill types enabled, this will allow the user to set which type of bills to be accepted on the validator itself. Bill Validator Operation Notes Firmware sets Bill Validator to accept 1, 2, 5, 10, 20 US bills by default Any commands to changed bills accepted or held in escrow will be set back to the firmware defaults upon a cycling of power or reset. VMC Commands for Bill Validator US Bills Bit 0 = $1 Bit 1 = $2 Bit 3 = $5 Bit 4 = $10 Bit 5 = $20 BILL S ACCEPTED Bill Type 34h 4bytes Y1 Y4 Bill s Accepted Y1 Y2 = 001Fh for all US bills accepted = 0000h accept no bill s For example: Send the command: h Bill s held in Escrow Y3 Y4 = 001Fh for all US bills held in escrow = 0000h for no bill s held in escrow Send out 34h and then the 4 bytes Y1 Y4 to change bill s accepted and held in escrow. For example: Send the command: 34001F001F Enable the ESCROW, can accept the $1, But the coin go to the cash box directly BILL S IN ESCROW ACTION Escrow 35h 1byte Y1 Return bill Y1 = 00h Stack bill Y1 = 01h Send 35h and then Y1 to act on bill held in escrow For example: Send the command: 3500h to Return the bill Page 3 of 7

4 The bill acceptor will reply: 00 and also following two data bytes: 30 A3 to show the bill type returned Send the command: 3501h to accept the bill to the bill stacker box The bill acceptor will reply: 00 and also following three status data bytes: to show the bill type returned STACKER STATUS Stacker 36h response Z1 Z2 Byte1 Byte2 Fxxxxxxx xxxxxxxx F=1 Stacker Full Xxxxxxxxxxxxxxx = Number of bill s in stacker Send out a 36h to the Bill Validator It will respond with 2 bytes Z1 Z2 For example,if the bill stacker is not full and already stacked 3 pcs bills,then would reply BILL VALIDATOR All values are in hex MDB data from Bill Validator to the PC Bill Accepted $ $ $ $ $ Bill Returned All valid bill types disabled in software $1 30 C0 09 $2 30 C1 09 $5 30 C2 09 $10 30 C3 09 $20 30 C4 09 Bill Held In Escrow $ $ $ $ $ Bill forcibly Removed $1 30 A1 09 $2 30 A2 09 $5 30 A3 09 $10 30 A4 09 $20 30 A5 09 Bill Validator Status Page 4 of 7

Coins Dispensed Manually (Byte1) (Byte 2) 1yyyxxxx zzzzzzzz yyy = The number of coins dispensed xxxx = The coin type dispensed zzzzzzzz = The number of coins in the tube The coin types are: Type 0 = 5c Type 2 = 25c Type 5 = $2 Can. Type 1= 10c Type 4 = $1 Can. Note: The type of the coin is the same as the bit that needs to be set in the mdbcointype routine in order to enable the acceptance, or distribution of that coin.
