Our team had this exact same problem. We had to install the Labview VISA drivers to get it to work. That was kind of a pain because the VISA driver download was something like 140 MB and included drivers for way more stuff than just a serial port. There may be an easier way to get the serial port to work with the camera code provided, but we sure couldn't figure it out. I don't remember the exact link, but just go to ni.com and search for "VISA". Their search engine is very good. If you can't find it, e-mail me at
drk@current.net and I'll ask our programming guys what the exact address was.
