Does anyone know how to easily convert Wiegand to RS232? It seems most RFID readers output Wiegand code and I don’t know how to read that in a Windows PC from a COM port.
Wiegand has 2 data lines D0 & D1 and when D1 is pulled down to 0V this indicate a 1 and D0 pulled down to 0V indicate a 0. But it does not seem you can just put these as the input to a USB-RS232 converter?
