Is it possible (and as easy as for GPIB) to develop labview drivers for USB devices?

I dont want to use GPIB at all, just USB.
Thank you in advance.

The best way to call your USB device would be through your USB driver. The third party device vendor should provide a driver (dll) that can be called from LabVIEW using Call Library Node.

  • LabVIEW drivers for Agilent Noise Source 346B and Signal Generator E8257C-520

    Could anyone please tell me where to find LabVIEW drivers for Agilent Noise Source 346B and Agilent Signal Generator E8257C-520. I did not find them on NI's web site. Thank you!

    To my knowledge, the Agilent 346B Noise Source is not a programmatically controllable instrument and therefore we can't create an instrument driver. I suppose it is possible to be controlled through an instrument (like the PSG) but I don't see any documentation on this.
    As for the E8257C, we are insterested in providing a LabVIEW driver for this instrument series. Let me know if you are interested in assisting our development effort by loaning us the instrument.

  • Labview drivers for Prisma QMS

    Hi,
    I'm looking for labview drivers for the Prisma Quadrupole Mass Spectrometer
    from Pfeiffer Vacuum. If possible also a simple rest gas analysis (RGA) VI.
    Can anyone help?
    Hans Rosink

    There is no driver available as the qmg220 uses OPC communication you can use labviews build in OPC functions.
    But the problem is that the "normal" labview OPC functions using datasoket are a little bit limited and when you need to adress many OPC items it may crash.
    Therefore NI is producing the LABVIEW DSC module which is avialable for extra money and with the main problem that you are not able to build stand alone applications without any extra licencing costs. Which makes problems if you want to sell your software or add it to the instrument you sell.
    On the other side the DSC module is a little bit to powerfule for the communication with the QMG220.
    Because of these arguments we decideed to use a OPC developement toolkit from Softing . 
    We started with the .NET developement but there4 was a reasonable memeory leak in Labview when using .NET event callbacks.
    This has been solved with Labview 2009f2 and up versions.
    Up to now we have made our communication with the Softing ActiveX control within labview.
    Now we are on the  point to switch bak to .NET. 
    When try the OPC connectivity from any third party opc API vendor and you are using a remote OPC from labview please tonst forget to add the line.
    ole.AuthnLevel = 1 to your labview.ini file. 
    Hope this gives you a first overview.
    We are not planning to build a easy to use driver for the QMG220 but we build a lot of vi's to control some functions and collect the data.
    Best regards

  • LabVIEW Drivers for Instruments on DIN-Messbus

    I'm trying to interface to a group of instruments supplied by Rabe Messtechnik in Germany. They are networked through the DIN-Messbus protocol. Are there any labVIEW drivers for the following instuments or the protocol itself?:
    PPM-60, PIT-1500, PDM-02, PWS-02, CIO-26, PNC-02, PSW-02.

    Unfortunately I was unable to find a driver for this instrument. Instrument drivers can be found on our website
    www.ni.com/idnet
    by searching for a specific instrument name.
    If you cannot find the driver by doing this, then you have couple of options. First, I would like you to submit a request for this driver at:
    http://www.ni.com/devzone/idnet/other.htm
    We develop drivers based on demand and popularity so the more requests we have for it, the greater the possibility that we will develop one.
    If you would like to try developing your own instrument driver (or modify the existing one), we have documentation, model instrument drivers, and driver templates to help at :
    http://www.ni.com/devzone/idnet/development.htm
    We also have a syndicat
    e of third party vendors that specialize in National Instruments' products and services. Some of the vendors specialize in driver development. I would suggest contacting one of the Alliance members at:

    I hope this helps.

  • Are there LabVIEW drivers for the MCC USB-501 temperatur​e logger

    I am looking to purchase the MCC USB-501  and use it to acquire the ambient temperature on an event driven basis. The data logging portion is something I am interested in, I just want to have my application acquire the tempture when a certain event occurs. Does anyone have any LabVIEW drivers for this device?

    I don't know what you mean by using a logger that collects data on an "event driven basis".
    It is nifty little device, but it basically does one thing.  It logs data.  You load the software, configure it for when to start an how often to log data, unplug it, and put it where you want to log the temperature.  When you're done, you get it plug it back in and download the data that was logged.
    There is no way to configure it to react to events.  It's possible that a LabVIEW driver exists for this, but all it would do is provide an alternate way of downloading the data instead of using the software that comes with it.  It is not an immediate or interactive piece of hardware like a normal data acquisition card would be.

  • Once I upgraded to ML, I'm now finding that my Seagate Free Agent external hard drive is no longer being backed up by Time machine.  Do I have to wait for Seagate to update their drivers for this hard drive?

    Once I upgraded to ML, I'm now finding that my Seagate Free Agent external hard drive is no longer being backed up by Time machine.  Do I have to wait for Seagate to update their drivers for this hard drive?

    I tried your suggestion, and it's been giving me the message "Preparing for Backup" for the past 8 hours.  Does this mean TM is backing up my hard drive?  I'll give it a few more hours, but if nothing else happens, I'm not sure what else to do.  I'm not sure if there are any new external hard drives that are compatible with ML yet. 

  • Can some body help me to develop labview code for generating pulse to drive ac servo motor

    can some body help me to develop labview code for generating pulse to drive ac servo motor... i am using NI 9401 card ....tnx

    Driving an AC servo motor would (I missed AC on the previous msg) requires some complex hardware. This is generally done by drivers specifically designed for this purpose. I doubt you will be able to accomplish this with the hardware you currently have and it might be cheaper to just buy a driver for it and control the speed through the driver.

  • LabView drivers for Agilent 54830B scope or E4402B Spectrum Analyzer?

    Where can I find LabView drivers for the Agilent 54830B scope and the E4402B spectrum analyzer, or at least a driver for another instrument in the same families that I could modify? There are none on the NI site or the Agilent site.

    One thing that I have done several times is get a LabWindows CVI
    driver from Agilent. You will be provided with a .fp file. LabVIEW
    has a link under the Tools>>Instrumentation menu that allows you to
    "Import CVI Instrument Driver." This will take the function calls
    from CVI and build a set of VI's with the same name. The vi's will be
    wrappers for a dll that is used by CVI and other text based languages.

  • Looking for LabVIEW drivers for Aritsu MS462XX VNA?

    I'm looking for LabVIEW drivers for the Anritsu model MS4623D Vector Network Analyzer?  Have gone to Aritsu's site and downloaded their tools but no LabVIEW source found.   The other thing is whether anyone's developed LabVIEW interfaces to theirTools (Navigator or Power Tools or SCE)???

    Hi,
    Unfortunately, we do not have an instrument specific driver for this Anritsu model MS4623D. Here is a link to the drivers we do have for Anritsu. We may be able to get communication to your device threw another means. How does your device communicate? For example is it GPIB or Serial. We may be able to use an NI driver and a programming manual for your device and communicate with it in LabVIEW threw this.

  • Is there any labview drivers for Spirent 5500 wireless channel emulator

    Spirent 5500 currently doesn't have GPIB capability despite the connector on the rear panel. It is controlled via .net from a laptop. Labview drivers needed.

    Clarification:
    National Instruments would like to receive driver requests for all instruments that do not have drivers available on ni.com/idnet. Each request is being added to our instrument driver request database and considered for development. We try to develop instrument drivers according to popularity. Unfortunately, we cannot develop instrument drivers for all the requests we receive.
    If a customer would like to try developing his/her own instrument driver, we have documentation, model instrument drivers, and driver templates to help him/her in development. This information can be found on our web site: http://www.ni.com/devzone/idnet/development.htm

  • LabVIEW drivers for Newport 2010A tunable diode laser?

    My group aquired a Newport 2010A tunable diode laser and failed to receive the labview drivers for remote control operation.  Does anyone have this software?

    All,
       Here is a link to a clean photocopy of the EOSI 2010 laser manual:

  • Labview drivers for keithley DAS 1600

    hai all,
    I am searching quite for a long time for the Labview drivers for my Keithly Metrabyte DAS 1600 data aquisition card. Could any body provide me some weblink or some source from where I can download the drivers.
    thanks in advance.

    Dear Nanda
    Thank you for choosing National Instruments!
    National Instruments provides drivers for NI products only. If you need drivers for other third party hardware, you will need to contact the hardware manufacturer for the drivers and VIs to interface with LabVIEW. You can go to the download center for Keithley from this link and typing in DAS 1600 in the search page. This will bring up a section with downloads - wherein you can find driver updates. If you do not find information here, then you may need to call in tech support for Keithley to get the drivers.
    Hope this helps.
