If you apply any of the formulas and get a value equal to 256, use the value 255 instead; if you
get 4,096 with the 16-bit boards, use 4,095 instead.
You can use the following programming sequence to set up an acquisition to be triggered
using the hardware analog trigger, where the trigger source is the PFI0/TRIG1 pin:
status = Configure_HW_Analog_Trigger (deviceNumber, ND_ON, lowValue,
highValue, mode, ND_PFI_0)
status = Select_Signal (deviceNumber, ND_IN_START_TRIGGER, ND_PFI_0,
ND_LOW_TO_HIGH)
