Details

  • 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
  • Did found a comport chip and 2 Philips chips.

Todo

  • 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.
