Hi @augas111

first of all I have to correct the version numbers I was talking about earlier in this thread.  
Of course we are talking about CVB 13.X.X versions, NOT 14.X.X.

Now regarding your question:  
[https://forum.commonvisionblox.com/t/getting-started-with-cvbpy/241/22](https://forum.commonvisionblox.com/t/getting-started-with-cvbpy/241/22)

You have to set the desired settings you usually set in the GenICam.ini (by using any tool like GCBrowser or ManagementConsole) using the SetParameter() on the accesstoken.  
The names to adress the desired settings and thus the parameters for the SetParameter() are exactly the same as they are in the GenICam.ini that you can find in %cvbdata%.

Cheers  
Chris
