I recently bought several 7941e+ RFID modules to read 125kHz RFID cards. While a few of them work perfectly and read data at 9600 baud, I’m facing issues with some others that don’t seem to work at all.
Upon closer inspection, I noticed that the non-working modules have a sticker on the back labeled "WG," which I believe indicates they are configured for Weigand output.
My question is: How can I convert these Weigand-configured modules to UART so I can read data at 9600 baud?
Any guidance on reconfiguration steps or necessary hardware changes would be greatly appreciated.
