Number of NI-DAQmx devices

Hi,
I would like to know the number of devices (NI-DAQmx Devices)I have
installed in my system (those that appear in measurament and automation
explorer), How can I do it?
I want to do that because I need to kow if there are NI-DAQmx Devices installed in my system.
I use LV7.
Thanks in advance,
Toni.

then if you have installed MAX you can see what devices you have installed in your system, only open MAX and go to My System >> Devices and Interfaces, there would appear "DAQmx Devices" or something like that

  • Built application can't find DaqMX devices with VISA Find Resource VI

    My application programmatically finds all of my PXI devices using the VISA Find Resources VI with the following regular expression:
    (PXI[0-9]*::?*INSTR){VI_ATTR_S:LOT >= 0}
    This works with my built application on a PXI-8186 controller with LabVIEW installed, but when I created an installer to put it on another PXI-8186 controller without the LabVIEW development system, none of my DaqMX devices show up in my list of VISA resources.  They all show up in MAX, however.  I even tried creating a simple app that just has the routine which gets the resource list.  Ironically, the only PXI device that shows up in the list is a ZT1000PXI made by ZTEC Corp.  I also have a number of PXI-4437s and PXI-6120s in the chassis.  I tried setting the PXI option in MAX to report all PXI devices, not just registered ones, but that had no effect.
    This is a Windows 2000 OS running on a PXI-8186, with DaqMX 8.5.0f3 and NI_VISA Runtime V4.1, and LabVIEW Runtime V8.2.1.
    Does anyone have a clue why this isn't working? I've tried uninstallng and reinstalling NI-VISA Runtime, but it didn't matter.

    Hi wired,
    As I understand it, you built an application in LabVIEW 8.2.1 on a PXI-8186 controller. When you moved to a new controller, one without LabVIEW 8.2.1, the program to find your PXI cards returns only a third party device and not your DAQ cards, despite the devices being visible in Measurement and Automation Explorer (MAX). You have an Installer for your application that installs the runtime engines for VISA and LabVIEW and the DAQmx driver.  Is my understanding correct?
    You mentioned that you had tried setting the PXI option in MAX to report all PXI devices, not just the registered ones. By this, did you mean that you set the VISA option to Show all devices accessible to VISA? If you did not mean this, then I would suggest doing so. In MAX, you can expand the Software tab in the Configuration Tree to the left. By selecting NI-VISA, the VISA options become visible. You should select show all devices accessible to VISA as seen in the attached screenshot.
    If you did in fact select this option already, can I ask if you also enabled the NI-VISA tulip Passport? In order to do this, on the VISA Options page, under General Settings, if you select the Passports option a list of checked boxes appear. Select the Tulips option as seen in the second screenshot and then click the Save button at the top of the MAX window. You will then need to close LabVIEW or your application and restart it.
    I built a simple program to test this post, and until I followed the above steps, the only devices that appeared were my com ports. After doing this I was able to all of my DAQ cards.
    Could you clarify some things for me? When you said that the application works on a PXI-8186 controller with LabVIEW, was this the development machine or just a controller you tried the executable on and it worked? What is in your installer? Is the VISA version on the test controller the same as that on the development machine? And lastly, in MAX, do the DAQ cards appear under DAQmx devices or under PXI systems and can you communicate with them using a test panel?

  • What happens if i enter phone number while erssing ios device from icloud?

    I want to remove my iphone4 device from find my iphone over the cloud. Because i forgot the passcode of my iphone. Now i want to restore it from a backup.
    itunes wouldn't let me do it because "find my iphone" is enabled in iphone settings. Moreover i was able to remove device from icloud. But itunes still asking me to turn off "find my iphone" from iphone settings. What i am missing here? is it because I entered phone number while erasing ios device from icloud or something else?

    If you force it into recovery mode as explained here: http://support.apple.com/kb/ht1808 you'll be able to restore it.

  • Is it possible to add a device in simulated NI DAQmx device or modular Instrument?

    Hi, 
          I want to simulate PXIe 8115 module without hardware.Is it possible?If Yes Can I add the device in simulated NI DAQmx device or modular Instrument?
    Please Mark the solution as accepted if your problem is solved and donate kudoes
    Solved!
    Go to Solution.

    Hm, these are several very basic questions.....
    The controller (8115) is a "complete" computer excluding a housing, power supply and external cooling. The later three components are the chassis, in your case the PXIe-1062Q.
    The controller can be run by a Windows based OS (e.g. Windows 7) or Real Time ("RT"). So what do you have installed on the 8115?
    In either case, communication with that controller by an external, additional PC or laptop is best done by Ethernet. You can use different protocols on Ethernet like a customized TCP/IP based protocol or by using NI Shared Variables.
    NI DAQmx is a hardware device driver. The purpose of this is to use a National Instrument based measurement device in a computer. If you want to use an NI device in your PXIe system, it is very likely that you require to have DAQmx installed on the 8115 controller. DAQmx is available for Windows as well as for RT.
    DAQmx in this use-case does normally not provide you a direct access to the devices in the PXIe chassis over Ethernet by *any* external computer. You have to write an application which will be run on the 8115 controller to interface (or "relay) the data to your external computer.
    hope this clears things up,
    Norbert
    PS: You should ask your local NI branch to send someone to you.... i think a direct discussion with an NI employee should be beneficial for you. Normally, a sales representative is sufficient as NI sales reps are quite technical.
    CEO: What exactly is stopping us from doing this?
    Expert: Geometry
    Marketing Manager: Just ignore it.

  • DAQmx devices not recognized after reboot

    I have a PXI-1042 box communicating with a desktop computer over a MXI-3 bridge.  This system has been up and running for several years through four or five revs of code. I am currently running MAX 4.6.0f1, DAQmx 8.9.5, LV 2009 and TS 4.2.
    Lately when an engineer logs on, although all six  cards are recognized in the NI-DAQmx Devices configuration section, only three are listed as installed. All six cards are listed in the Chassis section. See attached screen shot. If the engineer logs out and reboots enough times, eventually all six cards are available. Any ideas on what may be corrupting  the configuration?
    The PC is a Dell Precision WorkStation 380 (Pentium 4) running XP SP3 with 4 GB of memory. The installed PXI cards are:
    Slot        Card
    1            8330 MXI-3
    2            2567 Relay Control
    3            6551 DIO
    4            6551 DIO
    5            2503 Mux
    6            6220 M series DAQ
    7            2591 Coax Mux

    MAX NI-DAQmx issue.JPG ‏83 KB

    John,
    Here are answers to most of your questions:
    Can you verify that the missing switch modules are always only the switch modules, or are other modules sometimes missing, too? 
               >> It is always the switch modules that are missing.
    Is the MXI Bridge always connected to the host controller?
    Is the chassis always powered up before the host? 
               >> Yes and yes.
    When the engineer repeatedly logs out and in, do the cards appear only one at a time, or do multiple formerly missing cards appear at once?
               >> They always come and go together.
    Once all cards appear in MAX, do they remain until the machine reboots (even if you log out or in)?
               >> Not positive on this one. I'm 90% sure they come and go, even with just logging in and out.
    When cards are missing, does the device manager list the cards under the NI Devices section, or are there any bangs?
               >> Not sure what you are asking here. Is this the "NI-DAQmx Devices" section that is highlighted in the screen shot? The center panel is what is listed when this section header is selected (as shown). What are "bangs"?
    Thanks for your help

  • How to include DAQmx device drivers in installer (LV 7.1)

    Hi,
    We would like to build an installer that packages all required device drivers and does NOT require a separate installation from the DAQmx device driver CD.
    How can we do this?
    LV : 7.1 with Application Builder
    H/W : USB-6009
    DAQmx : 8.0
    Presently, we use the DAQmx device driver CD (that accompanied the USB-6009) to install the drivers. We do not want to do it this way because:
    1) It makes the installation a two-step process - (a) install DAQmx from device driver CD (b) install our application
    2) It installs a lot of drivers which are not required by our application.
    Thanks,

    Hello Gurdas,
    This question of yours brings up an issue we addressed when we released LabVIEW 8.0.  In LabVIEW 8.x and later, you have the option to package multiple additional installers with your application installer. 
    The issue you are having is limited by LabVIEW 7.1, as it is capable of including only one additional installer.  However, if you would like to create an installer in LabVIEW 7.1 and have it launch multiple additional installers, your only option is to create a batch file and have the LabVIEW 7.1 installer call this batch file. 
    We have KnowledgeBases available to explain this issue and the topic of creating batch files.  Here are a few of these documents:

    Sorry if my English isn't correct because of I'm Italian.
    You must switch on the lost mode on the app " Find my iPhone ".
    If you can see it on the map of this app, you will know where is your iPhone in that moment.
    REMEMBER: you can see your iPhone on the map of  " Find my iPhone"  only if it is online. Indeed you can't see your iPhone if it's offlined or switched of.

  • In Max 3.1.1 no daqmx device works with its test panel or self test

    I have a NI-5122 device and since loading DAQ 7.3 no DAQmx device appears to work.

    The NI-DAQ installer provides all the files necessary for MAX to detect the NI-5112, but not for the NI-5122. The NI-5122 will not show up in MAX until NI-SCOPE is installed.

  • MAX corrupt? error -88302, odd DAQmx device list

    My ATE stopped working Sunday morning with an error (I didn't witness it) that led me to a corrupt NI-DMM driver.  I've had this happen a few times before so I repaired it (in MAX).  This didn't fix my ATE.  The sequence of events gets fuzzy here, but at some point stepping through the TestStand sequence helped me find that the PXI-2570 wasn't operating.  I had an error message that suggested that the MAX database was corrupt, so I deleted the Data directory and restarted without without resolving my problem. 
    The configuration in MAX shows a difference between this ATE and an equivalent system: 
    Notice that there's no green glyph near the PXI-2570.  That's what I'm focusing on now.  Also, why does that device not appear in the tree on the left?  It does in its sister ATE.  I swapped the card with a known-good one and it didn't improve.
    I reinstalled DAQmx 8.9.5f7 because researching another error (-88302) suggested that would help.  It didn't.
    Any suggestions will be greatly appreciated.

    Hey Jim,
    You are correct that the PXI-2570 modules should show up under DAQmx devices.  This leads me to believe that the DAQmx driver isn't installed correctly.  One possibility is that you have two different versions of DAQmx installed in different locations on your machine (yes, this is possible .  DAQmx isn't designed to work with concurrent instances and is likely confused, thus failing to load the 2570... alas, this theory isn't bulletproof, as the DAQmx 6233 is correctly picked up, but all bets are off when there's multiple DAQmx drivers installed.
    My initial recommendation is to remove all DAQmx installations, verify that there's no 'DAQmx' versions installed in MAX, and then reinstall the original DAQmx version on your ATE... no need to change the SW.  If this doesn't work, the easiest troubleshooting step to get back up and running is to image the ATE from another machine.  Of course, this doesn't determine the root cause, but I'd suspect there was a software configuration change.  In this case, error 88302 is an internal NI-ORB error and shouldn't be reported to the user in the first place... so I'd say something is bonkers with your DAQmx install.

  • How can Retrieve phone number on Blackeberry CDMA device?

    HI All,
    I am tring to retrieve phone number on Blackeberry CDMA device using Blackberry APIs Phone.getDevicePhoneNumber(false); but is is not working it is returning null string value.
    Also I can't send SMS using BB API (for CDMA Device)
    Can you please tell me what i do for retrieving phone number using my application.
    Thanks in Advance.

    Hi,
    Thanks for reply, I am trying my application on T-mobile 8820. Your solution is good and it is working, But this solution requires manually enter phone number in Options -> Advanced Options -> Sim-Card -> Scroll Down -> MenuButton -> Edit SIM-Phonenumber.
    Actully we don't want that user do these thing.
    I tried to get phone number via sending sms to short code that returns phone number, But for CDMA there is problem for sending sms by using BB API (invoke method), Because this API restart the application.
    Is there any other way to get phone number?
    Please reply.
    Thanks in Advance.

  • NI-DAQmx Devices disappeared in MAX Configuration

    From time to time, our application will hang (black screen), the reason of this black screen is the NI-DAQmx Devices disappeared under Devices and Interfaces.

    I have done that already, it will work for awhile, but then the problem will come back later after several On and OFF on the machine.
    I get this error message under System Event Viewer.

    I cannot duplicate the problem if I disconnect the computer from the machine "without" the NI cable connected. It seems this problem can happen when I have the computer connected to the machine.

    In Ubuntu, you can find the serial number of any USB devices that have been connected in /var/log. I see references to USB devices in the kernel log on my iMac, but I wanted to make sure there wasn't additional information elsewhere.
