Hi,
Unfortunetely, the power on state for the analog outputs of the 6711 is 0V and you are not able to change that. You can make sure that the card is at a set voltage every time LV exits if you put in code that sets the voltage to a specific point every time LabVIEW exits. But, you will be at 0V until LV or another program sets the voltage to something different,
