TTL NI 9401 edge work but not able to count frequency

Hello world

I have a CompactDAQ, and a NI9401. I used this hardware with labview to control the speed of the crankshaft. My sensor (optical) output a square wave, amplitude 0 - 5v, TTL compatible.

I check on an oscilloscope it is perfectly shaped tooth.

I connect to 9401, and I try these 2 simple .VI attachment and weirdely,.

the counting of edge work perfectly (and the increment speed matches the speed of the crankshaft)

But, the frequency meserment or pulse with or period, do not work

Anyone has any idea why?

(I struggled for 4 hours and I did not understand it)

Thank you very much for your help,

Guillaume.

Hey, I found my problem,

I need to plug the wire into the line 5 instead of 4

I chose ctr1 for example and then count dashboard ONLY works on number 4 and the frequency, period measuremnt etc work only on line 5.

hard for me.

Welcome,

Guillaume.

    Hello

    I have a Dell Latitude E5410 using Windows 7 ultimate with IE 8

    The laptop seems to be connected to the internet but not able to browse any websites. I checked with IE, Google chrome, firefox as well.

    restored windows in the last working restore point, still the same problem.

    scanned with the Microsoft Malware removal tool, as well as with both windows defender and no suspects were found.

    Tried all most all the steps online to reset the log ip so also the steps in msconfig that comes as a response to this community, but still the same issue.

    The address sometimes bar said as invalid address and take the url as http:///

    Checked the IP settings and able to ping both Web sites and also windows taking updates.

    The only issue is not able to navigate.

    What else can I do to solve the problem, with about reinstalling windows?

    Kind regards

    This means generally that you are connected to your network, but not the Internet.

    If you use a wireless connection, this may mean the wireless network password which is stored in your computer's a mismatch with the router.  Try to connect with a cable.  Try to reset the password of your router wireless and rename your network.

    It is also quite possible that you have no connection to your Internet service provider.  Restart your modem and your router if you have separated.

    If the router is separated, try to connect with a cable directly to the modem.

  • Want to download 10 W but not able to do that, during installation, a problem arises and the previous operating system is restored.

    My laptop is preinstalled with Windows 7 Home Basic.  At the free launch Windows 10 I downloaded the same and after 2 months, the hard drive crashed.  The repair shop trying to fix formatting, but could not revive.  This is why I bought a new hard drive and repair charge shot Windows 7 Ultimate edition.

    Now, I want to download 10 W but not able to do that, during installation, a problem arises and the previous operating system has been restored.  When I posted the question about how to solve this problem, I was told to try the download by way of USB/ISO file.

    Now my question is that

    one) can I reload Windows 7 Home basic as I have the product key?

    (b) I can then download Windows 10 according to the normal procedure?

    I'm not tech savvy, afraid to download files in USB and then load into the laptop, so this question.

    Concerning

    S Subramanian

    Original title: Windows 7 Home basic

    You can directly download Windows 10. Windows 7 complete edition currently installed is not genuine.

    When you upgraded from a previous version of Windows, what happened is that (your PC) hardware will get a digital right, a unique signature of the computer which is stored on the Microsoft Activation servers. The real Windows 7 or Windows 8 license you were using previously will be exchanged with a key to the diagnosis.

    Whenever you need to reinstall Windows 10 on this machine, go just to reinstall Windows 10. It automatically reactivates.

    Therefore, there is no need to know or get a product key, if you must reinstall Windows 10, you can use your Windows 7 or Windows 8 product key or use the reset function in Windows 10.

    The column name is "mahesh tyagi" is simply displayed it shortened to sqlplus due to the known values in the column length.

    create table year_test select to_char (sysdate, 'yyyy') "mahesh tyagi" double;

    You can change the way sqlplus displays the header of column with something like
