Joey,
Unfortunately I was unable to find a driver for this instrument either at http://ni.com/idnet. This leaves you with one of a couple options. It may be possible to modify an existing driver to work with this instrument. Otherwise, http://www.ni.com/devzone/idnet/other.htm states a few options to obtaining a driver. Drivers are developed based on demand and popularity so the more requests, the greater the possibility that one will be developed.
