How to set up HR4000

[CREOL_LIBS]

Hello,

I'm trying to use my HR4000 Spectrometer with LabVIEW 2010.

I currently have VISA 5.1.2, I've installed the Ocean Optics 2000 4000 driver as well as the HR4000.inf file. Afterwards I used VISA to create a resource which is recognized by LabVIEW, by recognized I mean it shows up as a resource option in the VI.

The VI I'm working with is the Acquire Continuous Waveform.vi which is one of the examples provided with the 2000 4000 driver, and when I run it I receive no errors but also no waveform appears.

What am I missing?

Explain 'I used VISA to create a resource'. I hope you don't mean you used the VISA wizard for the USB connection.

Uh oh, yes that's exactly what I meant...

[Dennis_Knutson]

Why? That discards the inf file you got with the driver. You need to undo everything and use the provided windows driver.

     Sorry, relatively inexperienced with LabVIEW in general and especially so with anything other than a DAQ. I've been given a spectrometer and told, "Here, make this work." by my research advisor.

     I used VISA to make a new one because originally, I tried using the inf file provided with the driver and I was met with the same issue. So now, I've removed the VISA driver(s) I made and am using the HR4000_vista.inf file provided with the Ocean 2000 4000 driver. When using the VI's, two visa resource names show: LPT1 and USB0::0x2457::0x1012::NI-VISA-40001::RAW. Running with either one still does not produce a waveform.

Thanks for your help so far.

That looks like the VISA wizard resource. Did you also delete the compiled version of the driver? What does windows device manager say is being used?

[CREOL_LIBS]

My apologies for the delayed response; I've been out of town without internet access. I went into my program files and deleted any files that I created with VISA however I haven't checked what the device manager says.

I'll be in the lab tomorrow to find out more.

Under the device manager it reads the HR4000 as an NI-VISA USB device

Then you missed something. Did you also delete the pnf file?

Hello I face the same problem here; I just find no clues out. It's Win 7 64 bit, LV 2011 32bit.

Following original post, I see no waveform out.
