Not needed on latest versions (> Armadeus 3.0): the tool is installed by default. Informations are kept here.

Usage

To set the DAC outputs to a given value, use the setDAC command:

 # setDAC
 
 ##Usage: setDAC OUTPUT [VALUE]
 power down or set DAC output with value 0 - 1023
 
  OUTPUT is A , B or AB (both)
  VALUE must be 0 - 1023
 
  If no VALUE is given, then the output is powered down
