I was wondering if anyone had any success with communicating with the Nitgen FIM3040LV fingerprint scanner. I wrote a VB program and interfaced it with the computer just to make it easier to see what was going on. The device is sending and receiving correctly but nothing I try seems to activate the enrollment or identification.
Thank you,

Sure enough, I actually am building something involving that finger print system and the arduino. I actually wrote a whole bunch of code to do a variety of different functions with the Nitgen unit.
Originally I had a little trouble (well, a lot) because I had assumed that the arduino and nitgen units were the same endian. They aren't. They are backwards. That could be a big portion of your problem. Also, the nitgen wants RS232 signalling not TTL so you need something like a MAX232 chip.
