Have you tried contacting Xenics? Don't know about your particular situation, but I know they have been helpful with providing some software in the past.
Also, as said, you can get Pleora's eBus SDK and use the included Coyote. It can see and reconfigure most GigE cameras from its connection menu, then can display the video output. None of the analysis or camera-specific functions, but a good check for functionality and video, and includes a command line that can let you reconfigure things you know commands for.
