MAX Camera Settings after Restart

[Vladimirek]

Hi all,

I have some trouble with MAX & camera settings.
I open MAX, set camera atibutes (gain, shutter, offset), save settings, close MAX and run my aplication with fine results.

After restarting PC:
When I have run my application first time the settings are not good (brightnes isn't correct) and I must close my application and run it once again. Now is everthing OK.

I didn't change any camera parameters in my application, just open "as is" via "cam0".

Using :
    WinXP
    LV 8.0.1 PDS (Developer Suite February 2006)
    NIIMAQ1394 2.0.2
    NI Vision 8.0

best regards,
    Vladimir

Vladimir,
sometimes it depends by the camera if the attributes are set as default. In most cases the camera set all attribute to an internal camera default after repower the camera again.
Solution is to save all settings in a dat file in LV and call this file and set these parameters to the camera before start the acquisition. In my opinion this is the best way.
Take a look into my attached files.

Regards,
Steffen
