imaqhwinfo without gain parameters from NI-imaq



I can find a camera adapter and camera with matlab Image
Acquisition Toolbox using a.o. imaqhwinfo. Next I can
create an video-object using the ObjectConstructor. From
this video-object I can ask for its Properties using the
get-function. And finally one of these Properties is the
Source with typical fields like Gain and Exposure values.
This works for several adapters, although the actual
fieldnames for gain and exposure can differ.
I just updated to Image Acquisition Toolbox version 3.0
because this supports camera link interfaces from National
Instruments with NI-IMAQ 3.7.1. I do get a connection, but
I cannot find the camera parameters such as gain and
exposure.
Where can I find and set camera gain and camera exposure
from within matlab when using a NI-framegrabber with NI-
IMAQ 3.7.1 ?
