You could find a LV/CVI driver for this instrument at http://www.ni.com/devzone/idnet/default.htm . If it's not listed there, it leaves you with one of a couple options. First, I would like you to submit a request for this driver at: http://zone.ni.com/idnet97.nsf/instrumentdriverrequest/
We develop drivers based on demand and popularity so the more requests we have for it, the greater the possibility that we will develop one.
If you would like to try developing your own instrument driver (or modify the existing one), we have documentation, model instrument drivers, and driver templates to help at :
http://www.ni.com/devzone/idnet/development.htm
We also have a syndicate of third party vendors that specialize in National Instruments' products and services. Some
of the vendors specialize in driver development. I would suggest contacting one of the Alliance members at:

An instrument driver is a collection of functions that implement the commands necessary to perform the instrument�s operations. In short, someone read the instrument user manual and implemented some of the functionality in a program for the end user. Instrument drivers are not necessary to use your instrument. They are merely time savers to help you develop your project so you do not need to study the manual before writing a program. With all of this work already done for you in the driver, instrument drivers can significantly reduce development time.
There are examples in LV/CVI on Instrument Connectivity. I would suggest tweaking them to suit your application. Also the specific command that your instrument responds to can be found from it's manual.
Some useful resources for your application are

Hope this helps.
