interfacing cama s20 with 8051

i am interfacing cama s 20 (fingerprint scanner with microcontroller 8051?i am new at this .what should i do .plz help

You should contact the "cama s 20" folks and ask for the technical details on how to accomplish this...

they have sent me a user guide .but its rubbish,i cant understand it.i am attaching it

I'm with cragyon, contact the manufacturer. As far as sorting through the manual of both systems your trying to interface, I think you will have some challenges getting folks on any forum to help you.

The knowledge set is very specialized and I doubt your going to get somebody to spend up to several weeks trying to figure this out for you.
