Overview
The MDB2USB™ is a Computer Peripheral for interfacing vending machine protocol used by various devices including: Dollar Bill Validators, Coin Acceptors, Coin Dispensers, Smart Cards, Foreign Currency, etc. This describes the Interface Protocol for the MDB2USB Hardware circuit. The MDB2USB™ interfaces any MDB vending device (6-pin molex/5pin MTA) to the PC via the USB port. The MDB2USB™ protocol is compatible with standard USB 1.0 Protocol.
Quick Start
Install the MDB2usb™ on a free USB port.
Connect 24Vdc power and MDB connections (6-pin Molex). Apply power. Check for LED1 (Green) indicating power is OK.
Install and run HIDCOMM_B.EXE AND SETUP.EXE from the MDB2USB directory on Disk or CD-ROM provided. Insert different dollar bill denominations, coins OR magnetic swipe, etc. and check to see that they register in the MDB2USB™ or MDBlab program. If all currency is registered the HARDWARE INSTALLATION is complete. Proceed to SOFTWARE DEVELOPERS KIT.

Install the MDB2USB™
It is time to install the MDB2USB™ itself and move on to the testing phase. Installation is relatively simple; there are only two connections that must be made for full functioning of the device. There are connectors on the edge of the board. The 6-pin Molex connects to the MDB devices. The final connector is a USB type A and connects into the back of the computer. There should be an open port on the back of the computer labeled “USB”

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 bill type number is also the
same as the bit # that must be set in order to enable the acceptance of the
bill itself. Ex. Set bit 3 to enable acceptance of a $10.
When all of the DIP switches on the BV are set to NOT accept any type of
bill, the validator’s default is to accept one dollar bills.
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 3 = $5 Bit 5 = $20
Bit 1 = $2 Bit 4 = $10
Bills Accepted
Bill Type 34h 4bytes Y1-Y4
Bill’s Accepted
Y1-Y2 = 001Fh for all US bills accepted
= 0000h accept no bill’s
Bills 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.
Bills 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
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
