  4. Data format • Header  read information • ADC  real data • TDC  record how much time we don’t have ADC • Trailer  double check number of ADC bins

  5. DecordFadc Get data Determine data type Header ,ADC, TDC, Trailer, end message PAW Recombination data (until end message is a IRQ)

  6. Data ID
