How to detect connect and disconnect of DAQ(5133)

When 2x5133 connected, need to report to user that they are connected.
When they are disconnected, need to remind user that are disconnected.
I am trying to make it as a loop, run the device finder again and again, is there any better method.
Any suggestion, thanks.

you should remove the laptop first before you disconnect, and connect the power to the ultrabase first before you dock.

  • How do I connect and detect a high frquency pulse (0-3500hz) with a variable pulse voltage (0v low,5-10v high), on a SC-2345 connected to a PCI-6224?

    How do I connect and detect a high frquency pulse (0-3500hz) with a variable pulse voltage (0v low,5-10v high),  on a SC-2345 connected to a PCI-6224?  Labview doesn't generate a waveform if I try to graph the signal, and my analog input doesn'y recognize that the signal is even pulsing, only that it has a voltage.  Some advice would be much appreciated.
    Thanks in advance,
    Garrett

    Hi Garrett,
    It sounds like you want to do Frequency Measurements of a signal that is somewhat digital.
    There are two ways you can really do this:
    Wire your signal to the counter input and use the Digital Frequency examples (Help > Find Examples > Browse > Hardware Input and Output > DAQmx > Counter Measurements > Digital Frequency)
    Continue taking analog measurements and use some sort of logic to determine where you are getting rising and falling edges.
    I would recommend doing method #1, but you must determine which one is the best for your system.
    If you want to connect to the counter pins then you will find the
    terminals located on the side of your SC-2345.  If you don't need
    to condition your signals then simply wire everything into the proper
    pins for your counter (below).

  • Smart connect not detecting connections and phone not detecting headphones

    Hi
    The smart connect app in my Z2 used to auto launch the profile i set when my Blue tooth ear phones connect and disconnect but not anymore. Force stopping the app does not work. It was working before the lasted android update.
    Also my phone has stopped detecting my beats plug in headphones. Again it used to work prior to the software update last month.
    Sony if you're reading this please issue a patch soon thanks!

    Did you also try to clear data for smart connect?

  • Every time I connect and disconnect my iphone/ipad windows vista opens windows media player in the background.  It then hogs all of my cpu.  Does this happen to anyone else?

    I am running iOS 4.3.5 and this has been going on for months now.  I need to keep my task manager open to kill the task when I connect and disconnect my iphone or ipad.  It hogs all of my cpu, sometimes opening 2 or 3 windows media players.

    Sorry, just to confirm, I DID NOT ACTUALLY ANSWER MY OWN QUESTION!
    I replied to the previous message from my iphone and I managed to hit the link to "This has answered my question" by accident!
    I AM STILL LOOKING FOR A RESOLUTION TO MY ORIGINAL PROBLEM. CAN SOMEONE ALSO NIW TELL ME HOW TO GET RID OF THE GREEN TEXT TGAT SAYS TGAT MY QUESTION IS ANSWERED? That is a pain! It should at least ask you to confirm that your question is actually answered and you didn't hit it by mistake, like I did!

  • Microsoft Messenger or Ebuddy connects and disconnects

    Hello
    I've just bought my iPhone 4 a month ago. I'm very happy with it (formerly a BlackBerry user) but there's an issue that is driving me crazy. I've installed Microsoft Messenger and it connects and disconnects every 3 minutes. Also I've tried with Ebuddy but it has the same behaviour. It's quite strange because with BlackBerry I had no issues regarding this app
    My carrier is Movistar (Colombia) and I have an unlimited data plan
    Do anybody know how to solve this? I've read the Messenger's reviews on the Apple Store and it seems that a lot of people (in Latin America at least) are having the same problem
    Thank you

    You need to contact Microsoft about a problem with their iPhone app and the same for the app developer for eBuddy.

    did all the resets and still wifi connects and disconnects , plz help

    I upgraded Apple TV late last week. Last weekend I rented a couple of movies from Apple TV. I watched one immediately, and was going to watch the other one the next day. On Sunday I opened up Apple TV to watch the film, and..... NOTHING THERE. I could see 'purchased movies', 'top movies', etc., at the top of the bar, but no mention of rentals. Even the film I'd watched (which obviously you can see for 48 hours) had disappeared into a black hole in Apple TV. I have been charged for these movie, and sent in a complaint.
    My airplay seemed to be fine, but.... last night, my computer was not seeing an Apple TV or showing an airplay sing, so I restarted and the Apple TV and airplay sign returned. If I chose to watch the film on the computer it started up immediately, if I chose airplay, I got the first image of the film and the loading sign going on and on (round and round) forever. The film never started. I restarted my Apple TV, the same. I restarted the computer, the same. I tried with various programmes and no go.
    iMore has the following suggestion. I am not sure if this will help. It sounds a PIA, but if I can't get airplay to work, I might try it: http://www.imore.com/how-restore-2nd-or-3rd-generation-apple-tv-back-factory-set tings-itunes

    hi

    how the connection can be detected.
    also i want this whole process should be hidden there should be no taskbar button for these processes.

    It is very difficult to offer troubleshooting suggestions when the "os version" you are using is unknown as each os has their own troubleshooting solutions.

  • Problems when connecting and disconnecting MBP and TBD

    Hello,
    I have problems with connecting and disconnecting my macbook pro retina 13" to my thunderbolt display. Everytime I disconnect my MBP form my TBD with the lid closed it takes approximately 10 seconds until my MBP has recognized that the TBD is no longer connected and the MBP screens turns on.
    On the other hand I also have a problem when I reconnect my MBP to my TBD. Approximately every second time my MBP does not recognize that the TBD is connected again and neither the MBP nor the TBD turns on. The small light on the power cabel of my TBD does not light up. It is as the TBD would'nt have any power. Pushing buttons on my Apple Bluethooth doesnt help. I have to disconnect and reconnect the thunderbolt and the power connector a coupl of times until the MBP finally recognizes the TBD and turns on. In some cases a different background picture is shown on the TBD than the one I usually have on my MBP.
    The problem is very annoying especially because I connect and disconnect both devices and it really costs time.
    I really hope there's someone who can help with the problem. Do you think this may be hardware problem of my MBP or TBD?
    Thanks in advance for your help.

    HI there,
    The first thing I would recommend is checking for any new software updates while using the display, this will check for any available firmware updates for the display. If you continue to experience issues, then you may want to take a look at the article below for some further troubleshooting steps.

    Since upgrading to Mavericks, I have been unable to sync devices (specifically ipad mini and iphone 4s) to my MId 2013 Imac . They wil rapidly connect and disconnect, and I'm unable to do anything with the device. This happens with both USB ports.  Any suggestions?

    Obviously, syncing an iOS device with iTunes over USB is still supported in Mavericks. Calendar and contact syncing with iTunes is no longer supported. That has nothing to do with your problem.
    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).

  • My iphone 4s connects and disconnects (repeatedly) when connected to my computer

    my iphone 4s connects and disconnects (repeatedly) when connected to my computer, it works perfectly fine when connected to regular chargers, everytime i connect it to my computer it shows the charging symbol and then disconnects and reconnects in less then a second, it will repeat this process forever unless disconnected, sometimes it works perfectly fine and most of the times it does the same thing, I know for a fact its not the wire because i recently bought an ipad mini with retina and its usb is new, it worked with the retina for a day or two and then it kept connecting and disconecting repeatedly, my computer is two months old and i have new hardware in that machine, is it a problem in the usb power fluctuation? i am currently using windows 8.1 and i need solutions, this is super annoying, all my other devices work perfectly fine with the usb ports, all my usbs (2.0 and 3.0) do the connecting and disconnecting sometimes it even works ,what is the problem?

  • IPhone 4s connects and disconnects from Windows 8

    Apologies if this has been asked before as i'm sure it has but I can't find a solution.
    I have a new HP Compaq laptop using USB 3.0, when I connect my IPhone 4s to my laptop it connects and disconnects every seconds, I've looked in the device manager and can't find anything to do with Apple in there.
    Has anyone found a solution to this?
