Hi everybody
we use NI USB6210. Now I saw, that when I power up my PC and the card is connected or when I plug in the card when PC is up there is a short (about one sec) high pulse at all digital output pins
Is that a known behaviour and how can I get rid of it?
Thanks a lot

Hello Martin,
what are the power up settings in MAX?
What is connected to the device?
What voltage has the spike?
Which DAQmx driver is in use?
How do I Set the Digital Output Line Power Up State and What Boards Support Them?
For the analog output there is a Power On Glitch specification on page 3

Hello Alexander,
I got news in this case:
The board I used when I saw this pulse had a damage in the analog part, while the digital part seemed to be still working ok ie it prduced the levels I programmed.
Now I received a nes 6210 and tried this one too and it does not have this power up pulse or more precisely it is much smaller than the 0.8V low level maximum.
So I think the problem is kind of solved
Thank you for your help anyway
