NI Acquisition Assistant...how to control parameters (exposure)?

[joptimus]

Good morning guys,

I'm using a IDS UI-5490 RE camera (GigE) with LabView and the Acquisition Assistant. It works fine, and in the assistant I can control everything I like.

But from the outside of this express VI, there are no controls to set exposure for example. I can only select logging path and image prefix?

Do I have to do it without the assistant like it is explained here:

Thanks!

Hi joptimus

I just did some tests and noticed that if you select Continous Acquisition instead of Single Acquisition, you get the option to add the Camera Attributes to the Controls.

If you want to stick with Single Acquisition, you can either just set the end condition of the while loop around the continous acquisition to true or else you will need to work with the low-level functions.

However in this case I would recommend configuring a continous acquistion with the desired controls and converting the generated Express VI to a SubVI (Right-click "View Front Panel").

Then you can use this as a starting point for your own Acquisition Configuration.

Hope this was helpfull 😉

Best,

Corinne
