Hello,
If you want to communicate with your instrument you need to know the protocol to use. In your case it's serial so you need
NI-VISA. Then you must know that instrument drivers exist. You can download it in NI website. But unfortunatly we don't have the one you need, we only have
this one.
So you have 2 solution, either you develop your own communication based on serial commands, or you contact honeywell and ask for libraries of functions for LabVIEW (or any NI-based software).
I hope I have bean clear enough, and that it helped.
Regards
