Hi, Monton -
You did not state which platform you are wanting to use this fingerprint scanner with. If Windows 10, please be aware that your version of PB (v12) is not certified for Windows 10.
Without the the SDK from the vendor, I think your chances of getting this to work with ANY development software is very nearly zero. You need the vendor's Software Development Kit.
Also, this device is obsolete - it is no longer available from the vendor, according to this website:

There may be someone here that can help you (I hope there is!), but I would not count on it. You may want to consider other, more up-to-date scanners that have an SDK that works with your platform(s).
Or try to contact the vendor on the same site John gave you. Maybe they can provide you with what you need.
