Also we have a utility that will allow you to test whether your connection to the PINPad is working correctly.
You can download this from
ftp://ftp.highmeadow.com/pub/Support/Test_Verifone.zip.
This is a crude program that will allow you to determine if you are even able to talk to the PINPad from your computer and will only work if the PINPad is installed on COM1.
Once you have downloaded the file, extract the file to a convenient place on your computers drive and run the program. Run the program, type some text into box on the screen and then press the Set Text button. You should then see the text you typed on the PINPad's display. If not, you are having a problem communicating with the device. The most likely sources of communication errors are, the PINPad Cable, the serial port, and finally the PINPad.
