Hi,
I have an old ROM Security Wiegand randomising keypad which I'd like to connect to a PC or preferably a little PIC to make a basic security panel. It's one of those keypads where you press a button and the numbers jumble up so no one can watch you enter the code.
Question is is there any information on the protocol. I have a pinout, it seems to require 12V and 5V for the interface and has RS232 output...however googling wiegand interfaces result in some sort of 26bit protocol...I'm not sure if connecting it to a PC will result in proper decoding.
