CASH-Interface2
v1.31

---

Universal CASH Interface

- Simultaneous operation of a coin and bill validator as well as 3x hopper.
- Connection of cashless systems via PULSE interface
- Works on the USB port via MINI-B USB cable.
- The interface is monitoring six channels + power supply. Using BINARY Mode there are
  15 different bills and 31 different coins possible at the same time.
- The devices are disabled until the software activates them.
- The pinning of the connectors are designed for coin acceptors of the type NRI G13 - RM5 - EMP 800 -
  EMP 850 - Microcoin SP/QL - MEI CASHFLOW 330 - MONEY CONTROLS C120,
  CONTROLS C120, and for bill acceptors of the type NV9 or NV10. We offer also specially wired
  connection cables or adapters for all other types, e.g. NRI G40 or GBA HR1.
- External coin sorter control via hopper full signal (SRT / H-FULL jumper).
- Hopper full and empty signal detection.
- 2 free useable inputs, e.g. to connect push buttons.
- 2 free useable outputs, e.g. to connect lamps or other actuators. 1 output as relay contact.
- Watchdog function, that means the acceptance is deactivated on errors.
- The control of the devices is done with simple commands,
  or by the free available CASH-Interface2 software.

Connection

Connect the CASH-Interface2 with a MINI-B USB cable to the PC. Supply the interface with a direct current voltage of +5V and 12V. Ensure that the poles are connected correctly! Be sure to take the precaution of making sure the power supply is strong enough. A bill validator can take up to 1500 mA and a coin acceptor up to 500mA of current. A hopper can take up to 3000mA and more!


USB driver

Normally the USb driver is installed by Windows automatically when the CASH-Interface2 is plugged in the very first time. The CASH-Interface2 works with the latest FTDI driver v2.12.36.4

Available for download here: CASH-Interface2 FTDI USB driver 32+64Bit
The used COM port number is displayed in the Windows device manager, see Ports (COM & LPT).


Coin validator connection

The connection of the coin acceptor (e.g. NRI G13) is made by a 10 pole flat ribbon cable to the plug marked with COIN.

Occupation of the 10 pole plug (NRI G13 compatible):




Bill validator connection

The connection of the bill validator (e.g. NV7/8/9/10) is made by a 16 pole flat ribbon cable to the plug marked with BILL.

Occupation of the 16 pole plug (NV7/8/9/10 compatible):

Pin 1 = +12V DC Pin 2 = 0V Pin 3,4,5,6 = MDB (not used) Pin 7 = Busy (act. low) Pin 8 = Escrow (not used) Pin 9,10,11,12 = Inhibit 1-4 (Sperrung = High, Annahme = Low) Pin 13 = Vend 3 (Note channel 3, act. low) Pin 14 = Vend 4 (Note channel 4, act. low) Pin 15 = Vend 1 (Note channel 1, act. low) Pin 16 = Vend 2 (Note channel 2, act. low)

Pin 1,2,3 = +V (+12V DC) Pin 4,5 = -V (GND) Pin 6 = Full Pin 7 = Motor start (Pulse) Pin 8 = (not used) Pin 9 = Coin signal Pin 10 = Empty

If you want to connect other devices than Azkoyen you need to assemble a adapter cable with the above occupancy or use one of our adapter boards. We offer adapters for MK4 hopper and ND-300 bill dispenser. On request we also supply you with fitting adapter cables.

Our ND-300 bill dispenser adapter can be plugged into the CASH-Interface2 HOPPER connector. It offers the hopper’s motor run pin (OUT) and empty sensor (IN) so you can connect easily a ND-300 bill dispenser and use it in hopper mode.

The adapter can also be used to have an extra INPUT and OUTPUT for the CASH-Interface2 if there is no hopper connected. For example we use this for the photo booth control to have external illuminated push buttons. Hint: The output can switch a maximum current of 500 mA, on more load you have to connect a relays between load and output.

Connection of an illuminated push button on the HOPPER plug via ND-300 adapter:


Cashless systems connection

The CASH-Interface2 supports the connection of cashless devices via PULSE-Interface. To do this, simply connect the PULSE output of the cashless device to a channel, e.g. COIN #1 - #6. We offer a PULSE-Adapter for easy connection, see PULSE-Adapter

Currently the following credit and smartcard systems can be connected:

- Nayax cashless payments vpos => Instructions in PDF format: CASH-Interface2 Nayax Connection
- Ingenico pos solutions smart pos self-service
- CCV InSync
- Otiglobal cashless payment systems otipulse
- Sacoa Debit Card, POS and Redemption System
- USA Technologies ePort G9 and ePort G10-S


Devices settings

For simultaneous operation of coin and bill acceptor we suggest this configuration:
Bill validator and coin validator in BINARY mode. You have to adjust the channels of coin and bill validator accordingly. You can get the software and cable to reprogram the respective device from the manufacturer, or just choose the desired channel occupancy with your order.

Example bill and coin validator (bill validator BINARY mode, coin validator BINARY mode):
Channel 1-4 = bill validator binary coded value (up to 15 different bills)

Channel 1 (1) = bill validator 5 Euro bill
Channel 2 (2) = bill validator 10 Euro bill
Channel 3 (1+2) = bill validator 20 Euro bill
Channel 4 (3) = bill validator 50 Euro bill
Channel 5 (1+3) = bill validator 100 Euro bill
Channel 6 (2+3) = bill validator 200 Euro bill
Channel 7 (1+2+3) = bill validator 500 Euro bill
and so on
up to 15 different bills possible...

Channel 1-5 + 6 = coin validator binary coded value (up to 31 different coins)

Channel 1 (1+6) = coin validator 1 Cent coin
Channel 2 (2+6) = coin validator 2 Cent coin
Channel 3 (1+2+6) = coin validator 5 Cent coin
Channel 4 (3+6) = coin validator 10 Cent coin
Channel 5 (1+3+6) = coin validator 20 Cent coin
Channel 6 (2+3+6) = coin validator 50 Cent coin
Channel 7 (1+2+3+6) = coin validator 1 Euro coin
Channel 8 (4+6) = coin validator 2 Euro coin
Channel 9 (1+4+6) = coin validator token coin
and so on
up to 15 different coins possible...

Example for connecting a bill and coin acceptor (PARALLEL mode):
Channel 1 = bill acceptor 5 Euro bill
Channel 2 = bill acceptor 10 Euro bill
Channel 3 = bill acceptor 20 Euro bill
Channel 4 = bill acceptor 50 Euro bill
Channel 5 = coin acceptor 1 Euro coin
Channel 6 = coin acceptor 2 Euro coin


Programming

The software integration into your projects is done via default COM port commands or with the free CASH-Interface2 software (CI2.EXE). The source code of the CI2.EXE is available in the corresponding subdirectory. ( Download CASH-Interface2 Software )

ci2.exe


Another possibility to implement the CASH-Interface2 into own projects is to use the demo project. The CI2.EXE sends a WM_CopyData Message with every event in the format ID,DATE,TIME,CHANNEL,VALUE which can be received from your software. Additionally the program writes a logfile LOG.TXT in the same format, which can be evaluated externally from your software.

To load CASH.EXE on system run just put a shortcut into the autostart folder. Simply activate the HIDE checkbox to run it invisible in the background.


Change settings for coins and banknotes

If the connection to the CASH-Interface has been established, means the Com port is open, all settings have been read on port open from the CASH-Interface2 board and are shown in the software. Now the values for coins (COIN VALIDATOR) and banknotes (BILL VALIDATOR) can be set to any value of your needs.
Hint: In PARALLEL mode we only use coin 1-6 settings, this is shown in the software, too!

Now just set the coin or bill value for the corresponding channel.
Example: The coin validator has been set up to this, #1 - 10 Cent, #2 - 20 Cent, #3 - 50 Cent, #4 - 1 Euro, #5 - 2 Euro, so set for #1: 10, for #2: 20, for #3: 50, for #4: 100 and for #5: 200. Finally all settings must be sent to the board by pressing the "Write settings" button.

To verify the new settings are really stored correctly onto the CASH-Interface2, just send the command CASH_READSETTINGS by the "Send command" button, the CASH-Interface2 sends then all settings to the PC again. If "Log all events" is active all data is shown in the log. Alternatively close the Com Port and open it again, with activated "Read settings on port open" the settings are read again from the CASH-Interface2.


Commands

Commands to the CASH-Interface2 have to end with a "carriage return". In computing, the carriage return (CR) hexadezimal 0D or dezimal 13, is one of the control characters in ASCII code. The CASH-Interface2 detects a byte with the value #13 ($0D) as command end.

Example: CASH_READSETTINGS$0D

All data from the CASH-Interface2 ends with a "carriage return" and "line feed" (CRLF = Enter). This way you can detect the end of the data. When you receive the bytes $0D$0A all data has been received and the data can be processed.

The communication from and to the CASH-Interface2 can be tested with a terminal program.
COM port settings: Baud 19200, Data bits 8, Parity none, Stop bits 1, Handshaking none
