Update voltage s17+

[mike11d11]

I have one hashboard that was repaired and when i got it back it has a different volatage that the other original 2 boards at 1920, the new one is set to 1960. Does anyone know of a way to get this done. i actually purchased a Test fixture ZJ0001000001 model in the past that i never used, not sure if this can be used to update the voltage or copy voltage settings from one board to another? Can anyone provide some direction, much appreciated.
