    Re: Bill Acceptor Integration

    When code is running and connecting bill acceptor i got this output
    event listner calling == gnu.io.SerialPortEvent[source=//./COM5] and after i insert the bill no event fired or pulse recieved.

    Re: Bill Acceptor Integration

    i got this output
    event listner calling == gnu.io.SerialPortEvent[source=//./COM5]
    The red part of that message is text in the program that is printed with a println method
    The green part could be what is read from the serial port that is printed with a print method

    I don't understand why those two Strings are on the same line. The red String is printed using the println method which means that the next String that is printed should be on the next line.

    Re: Bill Acceptor Integration

    this is the statement

    System.out.println("event listner calling == "+arg0);

    thats why it print both simultaneously.

    I do not see that statement in the posted code. Do you have different versions of the program?
    Please post the code for the program that you are using for testing.

    Add a print statement inside of the while loop that prints each value of data as it is read so you can see if anything is being read from the serial port.

    Re: Bill Acceptor Integration

    Below is the code nothing is updated except this statement
    System.out.println("event listner calling == "+arg0); and output is same as previous.

    Code:
    package com;

    import gnu.io.SerialPortEvent;

    Re: Bill Acceptor Integration

    A manual that describes the ebds protocol is at http://gamingparts.eu/downloadfiles/197.pdf - unless you have a specific manual for the ebds interface for AE 2831 D10 E?

    Page 16 describes the interface. The first question is how is the 12 pin ebds connector connected to the serial port of the computer?

    Re: Bill Acceptor Integration

    Yes - but you haven't answered my question. Physically, exactly how is the bill acceptor using the ebds interface connected to the computer?

    Re: Bill Acceptor Integration

    output is same as previous.
    Try adding a print statement inside of the while loop that prints the value of data.
    To see if anything is being read.

    Re: Bill Acceptor Integration

    Actually am working on to integrate bill acceptor through serial port and event fired on that port.
    I worked on this approach.

    But this bill acceptor also support EBDS protocol so according to me this is the another way of doing integration.
    So i dont know about this as well.

    Yes added print statement but did not get any response .
    The print statement in the posted code is in the wrong place. It will only execute if the value of data is '\n'
    You want to see ALL of the values of data, not just the one.
    Move that print statement outside of the if statement so that it always executes.
