Issue Details

I have a Basler Ace camera that I am controlling with the Vision Development Module and IMAQdx. I found an example VI (see figure below) on how to configure the camera settings, such as exposure time. I can execute the VI without any errors. However, the new settings do not have any effect, there is no change at all in the actual image. How can I fix this?

Solution

Implement a wait of at least 200 ms after you have written a new value to the camera attribute (exposure time in your case). This can be done by inserting a sequence structure with a wait in it, as shown below. The purpose of the wait is to give the camera time to register and implement the settings that are sent to it, before grabbing the picture.
