Hello,
You may want to check with the manufacturer of this hardware to see if they have any LabVIEW software available for controlling it. If not, you have a few options. On the off chance that the CAS-140 controlling software has ActiveX functionality you can interface with it through a LabVIEW ActiveX container or refnum. This is unlikely, however. You can ask the manufacturer if their software works with ActiveX. If not, you could use the System Exec VI in LabVIEW to programmatically launch the controlling software...you wouldn't have any programmatic control over the software once it is launched, but at least this would allow you *some* control through LabVIEW.
One other suggestion...the controlling software most probably uses a DLL to communicate wit
h the hardware...if you find out from the manufacturer the available functions in this DLL, you can use a Call Library Node in LabVIEW to programmatically call the DLL and perform hardware functions. You can find more information on using Call Library Nodes in the NI Developer Zone (www.ni.com/zone).
I hope one of these suggestions gets you started in the right direction. Good luck with your application and have a pleasant day.
Sincerely,
Darren N.
