One more tidbit: in the CVB manual it is confirmed that different manufacturers implement exposure time differently.
The CV Gen API itself provides no dedicated function to dynamically set the Exposure Time directly.
Please implement Exposure Time settings as described in the Common Vision Box Manual in the chapter Image Manager - GenICam Library.
Here I am pointed to Image Manager (https://help.commonvisionblox.com/NextGen/14.0/md_theory_of_operation_image_manager__image_manager.html), but do not see more related information.
