Im learning Rails and I wanted to develop a small app to start testing myself. Now, I'm stuck in this problem.
At some point I need to extract data from a Time Atendance fingerprint reader. This one.
There is a actual software in charge of this task, but I want to do it inside my app too.
The device is connected in the same lan and the actual software connect to the port 485.
How can I connect to the device, grab data from the internal database, and be happy?
Thanks you all!!
