Jacques,
We currently have support for three versions of the C4742, you can check the
Hamamatsu Supported Cameras Directory in our FTP site and see if any of those three is equal to the C4742-95. This files are compatible with our digital framegrabbers, all three are compatible with PCI-1424, and the "-98" is compatible with the PCI-1422 as well.
Another option you have is to contact Hamamatsu and see if they have developed a camera file for it to work with our digital framegrabbers.
Contact us directly www.ni.com/ask if you would like to keep researching an NI-based solution, or check with 3rd party companies for compatibility solutions, usually manufacturers will know or a
dvertise which companies have compatible products.
Good luck!
Nestor.
