I'm using a NodeMCU, and a working code for reading Wiegand data, with this library.
I managed to successfully read the Wiegand signal from this device.
There is absolutely nothing coming to the mcu. Everything is wired identically as the working device.
According to the manual, everything should be working, but I am at a loss.
Can someone please tell me what I might be doing wrong?
The store clerk told me something about needing a controller that converts RS485 to RS232, but I have no idea what that means. I already made it work with another device...
