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
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?
For the analog output there is a Power On Glitch specification on page 3
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
