Howdy umars,
One place to look would be the
Instrument Driver Network (IDNet). I did a quick search for that particular model and didn't get any results, you might want to double-check that page. Maybe you can find a similar driver that you can modify to work with your instrument.
Creating your own plug-and-play driver from scratch is always a possibility as well. You can find an excellent Developer Zone article on developing LabVIEW plug-and-play drivers
here.
Warm regards,
