Control serial instrument using USB with VISA(by configuring in MAX)

[Vishal]

HI all,
I am using LV 6i. In my laptop I have USB port. I want to control a USB instrument using this USB port. At present MAX doesn't show the USB port. Plz let me know how could I configure USB port in the MAX.

I have USB to serial convertor. I want to control a serial instrument using this USB port. IS it possible to do ? How?

Thanks ,
Vishal

Vishal,

To my knowledge, LabVIEW doesn't support USB instruments perse. However; I would suggest that you go ahead and plug the instrument in, and start up MAX (or have it scan for instruments) to see if the instruments shows up.

As for the serial instrument, not a problem, I think. I used a USB-GPIB converter to control GPIB instruments from a laptop before nearly flawlessly (nearly!). All you have to do for your situation is determine what port the serial instrument is. Again, plug the instrument in through your serial/GPIB convertor (or better yet, use the native serial port) and scan for the instrument. You should get an instrument location that you can plug into VISA to talk to it from LabVIEW.

Good luck.

Using a USB-serial convertor to control your serial instrument should work. The port name (eg. "COM2") should show up in the Device Manager (if you're using Windows). You can then use the regular LabVIEW VIs to control serial ports (either VISA-Serial or the Serial compatibility VIs).
