Serial

  • 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.

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 second......
