NI-VISA takes a unique I.D. number for each USB device?

Hi all

I'm relatively new to LabVIEW and VISA Toolbox.

When you communicate with LabVIEW and a USB via VISA, VISA shoots a D.I. unique number for the USB device for each connection established?

I have reference: http://www.ni.com/white-paper/4713/en

Kind regards

Bryan

Bryan,

I don't understand what you're saying, so let me rephrase my answer and see that if this may help you - IF your device properly implements the USB standard and has a serial number, VISA uses this serial number.  If your device does not implement the USB standard correctly or if it does not have a serial number, VISA will do for you.

If your device has a serial number, the VISA can be used to communicate with it.  There are routines that detect and identify VISA devices connected to your PC.

    Hello

    It makes no sense to do it in PL/SQL when you can do it with SQL.

    SQL is generally more efficient than PLSQL.

    And can you explain why you don't want to use analytical functions?

    This will update your table using a MERGE statement and an analytic function:

    MERGE INTO line_table lt
    USING
    (
       SELECT ROWID rid, header_value, row_number() OVER(PARTITION BY header_value ORDER BY ROWNUM) rn
         FROM line_table
    ) src
    ON (src.rid=lt.ROWID)
    WHEN MATCHED THEN
       UPDATE SET lt.line_number = src.rn;
    

    The result is less to:

    HEADER_VAL LINE_NUMBER

    ---------- -----------

    ALAOF 2

    Adobe licenses should be transferred when changing users. Transfer the license allows the owner to register the software to their name again. Both the author of the transfer of the license and the recipient must complete a transfer of license form. The serial number of the product must be registered in the Adobe profile of the transferor to transfer the license. You must qualify under license transfer policy.

  • His number disappointed + B500 USB device not recognized at startup

    Hello

    We have 2 B500

    whenever I'm starting, after loading windows they give me an error "USB device not recognized" I don't know what to do any help will be greatly appreciated as it is strange that both machines are giving the same error.

    also on one of the machines the sound does not work, I tried to get out of trouble, the diagnostic says the speakers are working properly, but not her out at all.

    I'm kind of disappointed by these questions, we always buy at Dell, but we thought we would give Lenovo a chance, the machines were barely a few months, when the problem started.

    advice please?

    That error usually comes up when a non bootable USB device is connected. Check the Bios and make sure that the CD drive and HARD drive are loading first. That should solve your problem. If this is not the case, make sure that you don't have any USB stick or disk external HARD connected until the PC load.

  • get the maximum number for each group

    Hi, I am a newbie and work on a project for school. I worked this problem for a few days and made a bit of progress.
    I have two tables, student and register for a database of the College. I need to show students that have the most entries into each large. So far, I have:

    I get the correct results, but need to introduce the SSN and the Major of the studens. When I add in the SSN and major, as below, I get too many files.
    WITH COUNT_Q AS
    (
    SELECT B.NAME, B.SSN, B.MAJOR, COUNT (A.SSN) AS COUNTCLASS
    TO REGISTER A, STUDENT B

    SELECT *.

  • HP ENVY 4500: HP ENVY 4500 - number of pages per device

    Hi - is it possible to get a number of pages for each separate device that prints on my HP ENVY 4500? Thank you.

    Hi @Lid999,

    Welcome to the Forums of HP Support! I see that you are interested in a number of pages for each device that print to your HP Envy 4500.

    This option is not available, because the number of pages for the HP printer is the total number printed on this machine.

    I'm sure you can find a 3rd party software that can install on all devices to give you the number of individual pages, I suggest a Google search.

    I hope this helps!
