Coin Mechanism Driver Software
Built on experience.

This driver has been designed to work with CyberD Simple Surf 2 as a coin acceptor for the National Rejecters Incorporated (NRI) G13 USB range of acceptors. These acceptors are recognized industry standard and used in many gaming machines, vending machines and many more applications making it ideal for the Simple Surf 2 Cyber Cafe type solution.

The plug-in contains two modes of operation, the setup with user interface and running mode as a silent driver.

The driver can also be used in you own applications as it will output XML through a TCP/IP port for each coin drop, reporting its value. CyberD have developed SGP (standardized gaming protocol) to clearly define conversations between devices and applications.

Device Settings

Device Connected To:
Select the comm port, as seen in device manager / serial ports.

Connect to Host:
The default value is 127.0.0.1, this means the same computer as the driver is running on. If the main application is remote enter its IP address.

Connect on Port:
The TCP/IP port that your application is listening to.

Inhibit Settings:
By looking at the Device Details we can see channel 1 is 1p coins (GB0001A), channel 3 is 5p coins (GB005A) and channel 7 is 100p (GB100A) and we can choose to inhibit (not accept) a coin by unchecking its channel, the coin will drop through and out of the regect slot.

Device Details:
The driver will interogate the device on startup and get the coin values directly from the acceptor, in this way any currency can be used, for example 1 cent would appear as US001A.

SGP and XML

Below is documented the SGP conversation with the coin acceptor; the language is kept as simple as possible and should not represent a challenge to most programmers. The language is an extension of the TCP/IP protocol and it would be possible to have the main application on a different computer that then acceptor if required.

Example code is available upon request in many programming languages from CyberD technical team. Please contact support@cyberd.co.uk

The SGP conversation follows

On startup this message is sent to the host application

<SGP version="1.0">
  <msg id="START">
    <type>COIN</type>
    <value>NRi G13</value>
  </msg>
</SGP>

On receipt of a coin (eg 50p)

<SGP version="1.0">
  <msg id="CREDIT">
    <type>COIN</type>
    <value>50</value>
  </msg>
</SGP>

On receipt of a coin (eg £1.00)

<SGP version="1.0">
  <msg id="CREDIT">
    <type>COIN</type>
    <value>100</value>
  </msg>
</SGP>

You do not need to reply to these messages and your application just needs to listen to the specified TCP/IP port configured in the configuration screen.

Troubleshooting

There is very little that can go wrong with the driver but a few things you can check.

• Make sure the acceptor power supply is plugged in.
• Make sure the USB is plugged in.
• Make sure the virtual com port driver (From NRI) is installed.
• Try running the NRI test application in the NRI Demo folder to check the acceptor is working. (Remember to set the comm port in options)
• If this is all working this indicates a problem with your application
• Make sure the correct com port is selected in the setup.
• Make sure your application is listening on the specified port.
• Make sure you have the right TCP/IP address for the computer running your application.
• Make sure any local firewalls allow your SGP port.
• Is the CyberD SGP driver being launched by your application. (Check in Task Manager)

Please check all these before calling tech support as you will be asked to confirm you have checked these.
