Hi friend
Can you explain for what sort of application u are working with fingerprint.
The first thing you have to check whether his parameters such storing,searching of the finger image are fine.
For that you can use SFG demo software where u can load and install it in ur pc,and then u have to connect ur finger print module to the pc with the help of max232 and RS232 to USB converter but in our case we have programmer that is having max232 and we have usb connector to connect with pc,from that first u check ur module working well and then go for coding with the controller.
