NI USB 6210 at power up

[Mr_M_from_G]

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

Martin
