Device module
The GenTL standard uses the terms device and remote device for two related but different concepts. A remote device is a real camera, physically connected to a frame grabber. This is different from the device module we describe here.
The device module is the module that contains the frame grabber settings relating to the camera. This includes things like triggers and strobes.
The device module also acts as parent to one data stream, and can be viewed as the sibling
of the remote device. The most important functions of the device module are
DevOpenDataStream (to get access to the data stream) and
DevGetPort (to get access to the remote device).
