MDB2PC FAQs
A. Any device that is MDB compliant can be used with the MDB2PC.
Q.
What are the power requirements for the MDB2PC?
A. The MDB2PC works within the MDB specified voltage of 20-42VDC. Depending on what devices are connected you may need a power supply capable of 6 amps.
Q. What are the Mode Select Jumpers used for?
A. The Mode Select Jumpers are used to configure the MDB2PC for different bill validator manufacturers and for selecting between Operational Mode or HyperTerminal Mode.
Mode Select Jumper 1 Selects between Operational Mode (Jumper OFF) and Hyperterminal Mode (Jumper ON). Note: When HyperTerminal Mode is selected the PC can NOT send data to the MDB2PC. This setting disables the handshaking between the PC and MDB2PC.
Mode Select Jumper 2 Selects between Coinco Bill Validators (Jumper ON) and other brand devices (Jumper OFF)
Q. Where can I find the codes sent from the MDB devices?
A. The codes sent from the devices can be view in Hyperterminal. Set Mode Select Jumper 1 to the ON position. Open HyperTerminal (9600, 8, none, 1) and start the MDB2PC with the devices connected. Operate the device and the codes will be displayed on the PC. Note: You can not send commands to the devices through the PC while in HyperTerminal.
Q. When I send a command to the MDB2PC from the PC nothing happens. What Am I doing wrong?
A. 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 (toggle) in CTS line (generated by the
MDB2PC) set output buffer=string to be transmitted.
Place
contents of string in output buffer and transmit
Set DTR low after transmitting the entire string.
A. See Below
This command will reset the coin changer to its default operating mode. It will abort all communication and disable all acceptance until otherwise instructed.
Indicates the feature level of the changer.
Level 2: Supports
core commands. These are RESET, STATUS, TUBE
STATUS, COIN TYPE, and DISPENSE
Level 3: Supports level 2 and the Expansion Command

Z18 =
Tube Status 16 bytes
Indicates the greatest number of coins that the
changer definitely knows are present in the coin tubes. A bytes position in the
16 byte string indicates the number of coins in a tube for a particular coin
type. The first byte sent indicates the number of coins in a tube for coin type
0. Unsent bytes are assumed to be zero.
Note: If a changer can detect a tube jam, defective
sensor, or other malufunction, it will indicate the tube is bad by sending a
tube full status and a count of zero for that tube.
To dispense a coin or series of coins from the PC you must send the dispense command (0DH) followed by 1byte of data consisting of the coin type and number of coins to dispense.
Y1

Coin Types Dispensed -

Bits b3,b2,b1,b0 indicate coin type to be dispensed.

send the command string: 0CH FFH

Before trying to use the Level 3 commands you must have Coinmech with Level 3 command support.
All the expansion commands start with the code OFH and are followed by several different sub-commands (00H 04H).

b1 b31 = Avaiable for future use.
Currently the only available feature to enable is the Alternate Payout Method. For more info on the alternate payout method see Payout (02H) below.
To enable a feature a bit is set. Example: To enable
the Alternate Payout Method the last bit would be set (bit 0).
If supported by the device, this command will allow the coin changer to determine what coins to dispense for a given value. It will also dispense the least number of coins need to equal that value.
This value is expressed as the number of coin scaling
factors that would sum to the value. Example: USA system using a scaling factor
of 5, if the change to be paid out was 35 cents, then Y1 will equal 7.
This is the changers response to the last VMC payout command. Bytes are sent in ascending order of coin types. A bytes position in the string indicates the coin type. That is byte one is for coin type 1, etc.
ZZ1
=
Value of coins paid out since last time this command was sent. This value
is also reset each time a new 02H PAYOUT command is sent.
Bill Validator Commands
RESET

The reset command is used to tell the validator that it should return to its default-operating mode. The validator will reject any bills in the validation process, escrow position, and disable all other activity until otherwise instructed.
This command is used to look at the status of the bill validator. Used sends a 31H and the Bill validator returns 27 bytes of data.

number is the bills monetary value divided by the scaling factor. Unused
bill types are sent as 00H.
