Why does LabVIEW think the Analyser is not connected?

Hi All,
        this almost works but not quite.
        I have a specialised analyser from LeCroy called a CATC Protocol Analyser System Model 10k. It is for observing and supplying traffic on a SATA disc interface. LeCroy supply an automation library of ActiveX components for controlling it called SataAutomation.tlb. After registering this with a utility I found called ccrpregutil.exe the automation library became visible in labVIEW.
        As an exercise to prove that this can work from LabVIEW I have written a small vi, called Code Interface.vi on file and uses two of the (simplest) methods from within it. They should return the Serial number and the firmware version. The analyser is connected (via usb) to the computer and is powered up. Running the attached vi results in the following message. "Error -2147220975. Exception occured in CATC.SataAnalyser.1: Analyser device is not connected Code Interface.vi.".
So it thinks the analyser is not connected when physically it is. Does anyone know if I have to do something extra to "Connect" it. There is  not a method in the .tlb file to do this. All the methods seem to assume it is connected.
The chances that anyone has seen this exact problem with this exact instrument are small but perhaps someone has seen something similar.
thanks
George

Hi George,
I have been looking into this problem for you. First of all, I must advise you that it is not possible for us to replicate this problem since we do not have the required hardware. As a result, the support I am going to be able to provide on this issue is limited. I had a look into the error that you are receiving and it seems that LabVIEW can offer no explanation as it is undefined, it may be that this is a custom error message/code that was created by LeCroy.
I found this link to a Knowledge Base (KB) article that may be of use for you, it relates to communicating with 3rd party hardware in LabVIEW. Do you know if LeCroy provide another methodology you can try for controlling the device such as LabVIEW VIs or a DLL? Otherwise, I can only advise that a high success rate is usually achieved when using ActiveX with LabVIEW and that this issue may be due to a problem in the ActiveX library that is provided by LeCroy. For more information on ActiveX in LabVIEW, see this link. I will continue looking into this for you but I must reiterate that there is only so much I can do without having the hardware to recreate the problem.

    If you are using a USB hub, don't. Connect directly to the computer. Disconnect all other USB devices except for keyboard and mouse.

  • Why does Labview load the vi.lib directory on start of a VI?

    I am using LABView 8.0.1 and when I start a VI, it looks as if LabView is loading items in the vi.lib directory.  Is this normal?  I would not be concerned if I was using these items, but I am not using any of the libraries that are being loaded.  Given the nature of the programming that I am doing, I need to see it I can stop Labview from doing this.

    I guess the nature of the programming is misleading.  It is more the environment.  I have to make sure that the VI is not calling/doing anything that could show up as an entry in the security log.  The things that i am concerned about are things like smtp mail.  Is there a way to stop labview from loading items like this?

  • Why does my iphone 4 ios 6 not connect to itunes store or allow Passbook to do the same?

    why does my iphone 4 ios6 not connect to itunes store nor allow Passbook to do the same?

  • Why does most of the "system preferences" not load due to having an intel based mac?

    I used to be able to access ALL of the items in "system preferences". Since the upgrade to Mavericks, which the Apple Store did for me, I cannot use most of them. It won't load my printer information. I cannot access security and privacy, users and accouts, parental controls, etc. Sometimes a window pops up and says "Preference Error" could not load.....pane. Or it will say "Preference Error" (and something like) cannot load ....... because it's an intel based mac.  What the heck does that mean and why does it say that when I used to be able to access everything in the "System Preferences"? Please help! I'm sooooo frustrated and confused right now.  

    Since the upgrade to Mavericks
    In order to get the correct troubleshooting suggestions, please, please pretty please, correct/update your system profile.  Thank you

    I am trying to get my "Find my Iphone" app to work and after I sign in with my apple id and password, it keeps telling me Im not connected to the internet.  I click "try again" and it does nothing.   I double checked that I am connected to my local wi-fi and not sure what else to do.   Help!!

    Yes...i have tried that and it sure does connect to all the websites. 

  • Why does it say the phone could not be synced because the connection to the iPhone was reset?

    I have a new iPhone 6. I am trying to sinc the new phone to my iMac however it says "The iPhone could not ne synced because the connection to the iPhone was reset.
    What does this mean? what do i have to do next?
    I have restarted both the iPhone and iMac and started the process again and again however this message keeps coming up.
    Please help

    If you are using a USB hub, switch to a USB port directly on the iMac.

  • Why does "Edit In..." sometimes not connect to Photoshop?

    Why does "Edit In..." sometimes refuse not open the file(s) in Photoshop?  This happens with any of the functions from LR5 to Photoshop CC, on MacOS 10.7.  Usually works again after restart, which sounds like a memory issure or something like that. 

    Not sure why, not without more details.
    Is Wi-Fi turned on?  Does the iPhone 5 see the network? 
    What troubleshooting steps from http://support.apple.com/kb/TS1398 have you tried so far?

  • Why does labview forget the connections to the virtual channels in MAX?

    I create a bunch of virtual channels in MAX - some with double assignment to a single AI port.
    Context - a digital output controls a MUX to switch the inputs into the AI ports of my USB-6361(BNC) DAQmx; thereby allowing me to double up on the number of AI ports I can access (switching every 5ms).
    I can run the code without any troubles. I have now completed my hardware set up and and am now testing the integration with the code. This is where things become a little unstuck.
    Problem: some ports, over time, start displaying erroneous data that is not correct. It is not until I delete the virtual channel and re-create it in MAX, does everything settle and work. This 'bad' data is seen in the MAX test panels tab and virtual channels tab.
    What is going on - should I bite the bullet and program all port assignments (channels) within my code?
    Am i mistakenly killing a link between MAX and the DAQmx?

    natashw already told you that it's expected behaviour when you leave the analog input open. There are two aspects to this:
    1) The analog input amplifier is a high impedance operation amplifier. It's minimal stray capacitance is high enough that it gets charged through very small leakage currents in the amplifier input stage, but the high input impedance doesn't allow those capacitance to discharge quick enough to stay at a defined voltage. So your input is usually very slowly floating to one of the power supply rails depending what transistor side has a slightly higher leakage.
    2) You only have one analog to digital converter. To get multiple channels there is a multiplexer than connects the different input channels to this single ADC. When the multiplexer switches between from a connected signal to an unconnected signal those stray capacitance at the ADC amplifier input has been charged to a certain voltage from the connected channel. With only the internal impedance of the amplifier to discharge this capacitance after the multiplexer switched to an unconnected input, the ADC will simply see the voltage that the stray capacitance has been charged to.
    Having a low impedance amplifier input would solve that problem but create many more problems that would affect the measurement accuracy significantly.

  • Why does LabVIEW think I'm running Windows NT v5.1? I'm on XP Pro!!!

    I read from an application property. They show Windows NT v5.1

    XP is really just a label Microsoft put on the newest release of Windows NT. Instead of just changing the version number, this makes it appear as an entirely new operating system instead of just a new version of the same old thing. That's marketing for you.
    XP Pro should show as Windows NT 5.1 as you have seen.

    Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

  • Why does Labview allow a cursor in a indicator?

    Hello,
        Why does Labview allow the user to position the cursor with the mouse inside a numeric indicator? Users think that just because they can put a cursor they should be able to type something and enter data. Is there a way to disable/stop the user from putting the cursor in a numeric indicator?
    Regards,
    Kaspar
    Solved!
    Go to Solution.

    Disabling the indicator satisfies your requirements, but this is funnier.  It would be even better if I calculated the position of the indicator and the "entry point" and just kept the mouse from entering, but I have a project to finish...

  • Why does f12(preview in browser mode) not render the page correctly?

    Why does f12(preview in browser mode) not render the page correctly? Instead when i go to the main or original file, it renders properly? It is drriving me nuts! HAHA! Can anyone help? mainly CSS problem, div overlapping but when viewing from original file on browser not through F12, it renders correctly. CS5.5 DW. Thanks!

    just that one of it is a f12 (preview in browser) while the other one is going to the directory and clicking the html page by itself.
    F12 is simply a hot key that launches your browser.
    The only thing I can think of to explain this is that you have a local site folder someplace in addition to a testing server site.
    When you hit preview, your testing server on the localhost/ is being called up in the browser.
    When you open the HTML page directly, you're seeing the local site file with unparsed data.
    Try disabling your Testing Server in Sites > Manage sites > Edit...

  • I have an iPod touch 4th gen. why does it show the wrong album art only on my ipod and not on itunes? Is there any way I can fix it?

    I have an ipod touch 4th gen. why does it show the wrong album artwork on my ipod and it's fine on itunes. why is that and is there any way to fix it? please help!

    I think it can't find the right or any artwork and ends up putting junk in there.
    And can happen with artist and other tags.
    probably fine with commercial media but otherwise....? I think you have to manaully go in and edit
    I also don't like how it handles and stores non-Apple iTunes store content.
