Issue Details

I'm using an NI USB-6501 and I need to set the power-on state of the digital lines to high every time I turn the device ON. Is there a way I can set the device to this behavior?


Unlike other devices, you can't configure the power-on state of the digital lines in the NI USB-6501. The power-on state is set as input (high impedance) by default in this device. 


Additional Information

If your application requires the use a high power-on state, you can always use an external pull-up resistor to accomplish this behavior. For further information follow the article below.
