Hello,
The current version for NI-IMAQ 1394 is 1.0. This is the only version that has been released so there are not multiple driver and dll versions for this product.
The best way to find information on this product is to go to www.ni.com/support and search with the key words IMAQ and 1394 (or something similar). This will navigate you to the product information, manuals, and Knowledge Bases that reference the supported cameras for the 1394 drivers.
If you have any more specific questions then please let us know and we will be happy to help you.
Regards,
Andy Bell
