#Mdb converter vending verification
Therefore, when you develop a vending machine, you need to have an MDB age verification interface. In some countries, these products may be restricted to different ages, so the vending machine needs to confirm the age of the purchaser before the automatic vending. If you need to develop vending machines for selling similar products such as cigarettes or alcohol products. The programming interface is user-friendly. Up to eight (8) MDB compliant devices may be attached to a single MDB-RS232. Hardware interface comes with cables,user's guide and user's protocal. 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. The vending machine standard NAMA Multi-Drop Bus (MDB) may now be interfaced to a PC using the MDB-RS232.

Our Pro Engineer Version support the Age Verification interface. But Previous version only support 08H(Coin acceptor), 30H(Bill validator), 10H(Cashless device) But V2020 Version box, after powered on, all payment devices are in the disable status.Ģ020 Version MDB-RS232 support 08H(Coin acceptor), 30H(Bill validator), 10H(Cashless device), 60H(Cashless Device), 40H (USD interface). So if we connect the coin and bill acceptors to MDB box and powered on, Even PC is not connected, Normal MDB-RS232 will enable the coin acceptor and bill acceptor and is ready to accept the coin or bills. Normal MDB-RS232 will send the enable command to the connected MDB coin acceptor, bill acceptor and the cashless device, but the 2020 Version MDB-RS232 will not do the job, just start to poll the slave payment devices and VMC will need to send these commands. What is the difference between normal MDB-RS232 and the 2020 Version MDB-RS232 ? Working with bill acceptor,coin validator, card reader,cashless defvice, for vending machine,kiosk machine,kiosk information machine Multi-drop bus to RS232 or USB PC interface ( MDB-RS232 )

The relevant section of the spec here is 2.1, and the serial TX in our code is: To send a POLL (or any command), you set the TXB80 bit in UCSR0B appropriately depending on if the 9th bit ("mode bit") should be set or not, then write your byte to be sent to the UDR0 register. The master transmit needs to go to the RX on the AVR, and the master receive to the TX pin - the schematic in section 4.4 should really help here - just build that.

This board essentially implements the interface in section 4.4 of the MDB 3.0 spec, as well as including a 34v->5v PSU (if your AVR is drawing its power from the RPI, I guess you won't need the PSU part). Server -(Ethernet)-> Nanode -> Level converter / PSU -> Vending machine Have you seen this?įor our vending machine / cashless device, the connection is basically:

My theory is that the VMS thinks my silent peripheral is dead broke. While I have this device plugged in the VM is insisting that it is out of service. and that's as far as I'm gonna get tonight. Oh, they're smashed into the address? That's wierd. A few #defines and a couple of switch statements later and I had version 4. The mode and the data bytes were being sent in reverse! I flipped that around and added a bit of logic to display : and got this in version 3.īetter, but still gibberish to a human.

Sample output version was binary garbage until we figured out the bridge software serial RX needed a pull-up resistor. In effect mdb is passing everything to bridge to my computer. I'm using software serial to talk to a second arduino ("bridge") that's sending all the data via hardware serial to the PC running a serial terminal in Arduino software. I've got one Arduino ("mdb") connected with the optoisolators, using hardware serial to talk to the VM.
