Keystroke Edition - version history
Latest Version:
Date: 27.09.2019

This software package includes: ci2.exe keystroke edition. The ci2.exe keystroke edition can send a keystroke on cash in, e.g. F6, to any program. The keystroke as well as the repeats can be adjusted for every coin and bill channel separately. Fixed selling price and pay out change via hopper possible. External control via separate remote.exe or sndmsg.exe and parameter possible.

With a CASH-Interface2 and the "keystroke edition" software it is possible to carry out a simple cash payment system for e.g. the Social Booth Photo Booth Software from Photo Booth Solutions, for the dslrBooth Photo Booth Software from dslrBooth, for the Breeze photo booth software, or Sparkbooth photo booth software, as well as other software you can control by keystrokes!

The ci2.exe keystroke edition software can even create a credits.txt file, that can be used by other software.

Using the price control feature the on board relays can be additionally controlled. The relays switches on for the adjusted time when the cost has been reached.

Having problems work thru this checklist, this should help to fix your issues!
  • If the COM port is open, the answer from the board with all settings must appear in the log. If not, there is something wrong with the connection to the CASH-Interface2, or simply the wrong COM port setting. Important: Check tight cable connections and the power supply is connected correctly. Using a USB to serial converter the correct COM port number can be found in the Windows device manager, see above video.

  • Check all cables if they fit tight.

  • Remove all extension cables, e.g. USB extension cord or USB hub.

  • Disconnect the power cable on the CI2, then connect it again.

  • If the connection to the CASH-Interface2 is working, but no cash is accepted, maybe the TotalBlocking function in the software is activated. The yellow LED on the board must lit to accept money. If coins or bills are rejected with illuminated ACTIVE LED, either the cable or the cash device itself is broken.

  • Use a different COM or USB plug on the PC, and replace all cables if problems still appear.

  • If the PC main board offers a free PCI Express slot, it is possible to add a cost-effective PCI Express serial card to have a pure COM port available.

  • A COM port can be opened only once, so be sure the COM port is not open by an other application.

  • Be sure the coin validator is placed horizontal so the device can measure correctly.

  • We figured out that some customers using a serial touch screen, the serial touch screen driver screws up all other Com ports, which results in communication errors with the CASH-Interface2. Try to get a USB controller for your touch screen and uninstall the serial touchscreen drivers. Visit the manufacturer website of the touch screen and download latest touch screen driver, but be sure to do not install serial drivers. A working 3M driver can be downloaded here: 3M touch screen driver win32-64

  • Check the log file for error messages, this gives you hints what exactly is the problem.

  • Check the power supply for the board.
    Measure the +5V (green LED) and +12V with a Voltmeter.

  • Sometimes it helps to completely uninstall the software via Windows control panel, and do a fresh install. Doing this visit the CI2 website to download the latest version.

HINT: You can not reprogram coin and bill validators with the CASH-Interface! To change validator settings the orginal programming software from the manufacturer is needed.
