    Re: Bill Acceptor Integration

    I'll ask again - Physically how is the device connected to the computer. You keep mentioning serial, ebds etc but you don't describe how the device is connected. Which serial pins are used for what purpose on the device/laptop? Is a serial port on the computer used or a serial-usb converter used? Have you used a terminal emulation program (such as YAT https://sourceforge.net/projects/y-a-terminal/ ) to find out exactly what is happening on the computer's serial interface? IMO you should stop trying with your program until you can prove that the required signals, data etc are being received properly by the computer from the device.

    nside try
    data inside loop =0
    So that says the code in the while loop reads just one byte of data with a value of 0.

    Device is connected with USB cable with CPU and there is a separate cable to ON the device.

    Not used terminal emulation program .

    OK, so you are using serial-over USB. From the device documentation, what should happen when a bill is inserted - what control lines should change etc? Does the computer need to signal via a specific control line that it is ready to accept data (eg some devices require DTR or CTS etc set)? I've not a Java programmer, but I see nothing in the code in post#21 dealing with serial control lines?

    I would suggest you look into using a terminal emulation program. For testing serial communications - and especially when things aren't going as expected - I've found them invaluable. There are many available. YAT is just the one I've used previously. There used to be a basic one included as standard with Windows but I think this was removed from Vista onwards.

    Re: Bill Acceptor Integration

    Then the issue is with the serial interface - not the program. What does the device documentation say re the control lines, baud rate, stop/start bits etc etc. Unless you can provide the technical details re the serial interface, we won't be able to help much more as the issue at present is not the Java program.

    Re: Bill Acceptor Integration

    Do you now have proven connectivity between the device and the PC?

    Yes, Installed a driver for bill acceptor and it shows in device manager connected to com5.

    Re: Bill Acceptor Integration

    Ok, what does the device do when first connected to the PC?
    Does it send any message to the PC?
    Or does it wait for a message from the PC?

    When the correct message (or any message) is sent to the device, what is the device supposed to send to the PC?
