  • Works on 12 volt
  • On boot "beeps"
  • Reads RFID Mifair classic out of the box, no idea what and how
  • Has on the back: power, RJ45 port (9volt?), "kinda" PS/2 port
  • On PCB there are some connectors

  • Find the comport and see what it does

Serial/RJ45

  • Obviously not a network connection ;-)
  • The Ethernet connector seems to be an kind of serial connection, the 1st pin is the GND en the 8th pin is somekind of data line
  • The data captured looks a lot like the usage of the ISO/IEC 7813, which is used for standarisation on magnetic stripe cards i.e. creditcards.
  • Colourcoding
    • Brown= gnd
    • blw= -8.8v
    • gw= 9.3v
    • ow= -8.8v (data)
    • other= no shiz!
  • Settings Logic analyzer:
    • 50M samples
    • 24 Mhz freq.
    • 8 bits
    • 1 stopbit
    • no parity
    • LSB send first
    • inverted
    • no special mode
    • 19200 baud

PS2

  • A bit of a bitch, no idea what it is.
  • "Smartcable" according to the whitepaper, probably for programming/configuring.
