18.38 Transition to safe state

      DAQ STOP
      disable data transfer 1
      detector bias OFF
      FEE64 power OFF


      Can restart as follows

1) FEE64 power ON
2) DAQ RESET
3) DAQ SETUP
4) Enable histogramming
5) Enable waveforms
6) Detector bias ON
7) Restore ASIC settings
8) ASIC Control
9) FEE64 temperatures
10) System wide checks
     sync ASIC clocks
11) FADC control - calibrate ADCS for *all* FEE64s
12) System wide checks contd.
13) DAQ GO
14) Check ADC data item stats
15) Check WR timestamps

If all OK can re-connect to Merger/TapeServer as follows

1) DAQ STOP
2) enable data transfer 1
3) DAQ GO
