Hello-
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.
If you have any further queries, please let me know.
