I have the particle electron/photon EM18 rfid reader and want to connect it to my photon and read a tag. It’s my understanding that this should output a 9600baud string when I read a tag - is this correct? Do I need to hold as select pin high or low to do this? Does the EM18 output weigand or RS232 by default?
Is there any sample code or a wiring diagram that shows what each of the pins on the ribbon cable does and how they’re connected to/from the photon/EM18?
