In order of priority:

1-Control of BiasDAC's (8x) & reading of Polarity switches (8x)
   The BiasDAC's generate settings for gate voltages, 
   there is a hardware polarity protection switch for each DAC
   DAC update rate is typical < 5Hz
   Data for BiasDAC's from input fiber1
   Data from switches to output fiber1

2-Overload monitor 
  (on software request)
  Overloads in the SIGNAL UNIT are latched in the control module
  latched overloadbits are transmitted & latch is cleared
  Command from input fiber1
  Data to output fiber1

3-Signal Conditioning
  gain & mode settings for the modules in the SIGNAL UNIT
  The manual controls on the SIGNAL UNIT have to be in the
  "remote" setting for this control to be effective.
  Data from input fiber1

4-Battery check 
  (on software request)
  measurement of pos. & neg. battery voltage
  Command from input fiber1
  Data to output fiber1

5-Power control
  Supply switches for DAC/ADC1/ADC2/OPTION (batt.life)
  (note:SIGNAL UNIT is always powered to protect sample)
  Data from input fiber1
