Working with spectrometer, how to make compatible with LabVIEW and SpectraSuite at same time?

[Gregory]

Hi all,

I've been browsing the forums for a while looking at how people have interfaced with ocean optics spectrometers, but I haven't seen a reference to my problem. I have the HR4000 from ocean optics, and have been able to successfully use NI's drivers for it by installing it as an NI-VISA device over USB. Unfortunately, when I have it installed with the NI-VISA driver, I cannot use it with SpectraSuite (ocean optics' software). When I click "update driver" and it installs it as a regular USB device (as opposed to NI-VISA) it works with SpectraSuite, but of course not with my LabVIEW program. If anyone has a work around for this, please lend me any insight you can!

Thanks,

gregoryj,

In order for your device to work with LabVIEW it will need to use the NI-VISA driver.  Likewise the device manufacturer’s software will also need its own driver installed to communicate with the HR4000.  Unfortunately you cannot have multiple drivers installed for a single device.  As you mentioned manually replacing the driver is the only way to switch between control programs.

Hi, in my case, I have 4 USB outputs on my laptop, where one of them is used for Spectrasuite and other 3 are for LV.

So you don't have to reinstall drivers for the spectrometer, just switch between USB ports
