Can I get four inputs voltage reading from four sources at a time from NI USB 6009 DAQ

I had a photoquadrant detector with four quadrants . each quadrant have a positive lead.  If i connect each lead to the DAQ's a0, a1, a2, a3 terminals and common ground to one of the ground of DAQ. Is it able to read four voltages from four quadrants at a time . And how to take the data through labview. In the manuals it's not shown can you provide me an example program.when i configure daq i'am selecting acquire signals--->analog input--> selecting a0,a1,a2,a3---> then configuring each channel with voltage limits all. then ok. Afetr that on the DAQ VI how can I read these four values. Is it by giving add inputs and put number indicator to each data like that or any other way is there. If you help me it's a kind job

Use the DAQmx Read.  Choose a polymorphic case of N channels.  It is up to you whether you want multiple samples as a array, multiple samples as waveforms, or single samples.  The multiple samples as an array will give you a 2D array, the rows being the channel.  The other options will give you an array, an index for each channel.

    From this example it seems i can't :(
    Thx
    Alex

    For what you are trying to do the simplest solution is to have one socket per "stream" that is the way they are designed to be used.
    However, you can multiplex multiple stream over a single socket, but you have do the coding yourself or use a solution which does this for you e.g. JMS. (There is no support at the socket level for this)

  • On my Mac Pro how can I get voiceover to start reading at a specific point on a document?, on my Mac Pro how can I get voiceover to start reading at a specific point on a document?

    On my Mac Pro how can I get voiceover to start reading at a specific point in a document, and then continue on to the next paragraph and so on?  Thank you.  Ed

    Welcome to the Apple family!!!! 
    How can I cause the VO cursor(box) show-up/start?
    Press Control-Option and F5.   The F5 key is located on the top row of keys 6th key over.  This is a toggling "Keyboard Shortcut" for turning VoiceOver on and off.
    How can I move the VO cursor to various sentences or paragraphs of an article and have it start reading ... and perhaps even continue reading on to the next paragraph(s) ... even to the end of the article?
    How to read a website with VoiceOver
    Step 1:  Go to the Website
    A quick keyboard shortcut is Command-L.  This will jump you up to the address bar.  Start typing where you want to go.  i.e "www.thewebsite.com"
    Step 2:  Working with Webpage
    VoiceOver will automatically start reading the website.  You can pause the speech by hitting the 'Control Button'. 
    If VoiceOver does not being reading the webpage, then you might have to "Interact" with it.  If VoiceOver say "HTML Content" then press Control-Option-Space-Down Arrow to interact with the webpage.
    Use Control-Option-Right Arrow to move throught the website.  This will speak "EVERYTHING" on the page.
    Most website that I've found have their articles labeled as 'Heading'.  You can jump from heading to heading, by pressing Control-Option-Shift-H.
    If you'd like an itemized alphabetical listing of the site, press Control-Option-I 
    Press Control-Option-Space on the link or article you want to view.
    Step 3.  Reading from Top to Bottom
    Once you found and clicked on the the article/link, use the same 'Heading' command, Control-Option-Shift-H to find the title. 
    After finding the title, press Control-Option-A will start reading from the title on. 
    Note:  If there are any other items (ads, pictures, etc) it will read those too. 
    Tip:  You might be able to activate a feature called the 'Reader'.  The Reader isolates the article and elimanates the ads  The keyboard command is Shift-Command-R.  You can also find it in the Menu Bar (Command-Option-M) under the word 'View' then 'Show Reader'. 
    I am using a MACPro with OSX, probably Mavericks 10.9 (where would I look to see if that is the correct information?)
    You can find this information under the 'Apple menu' in the Menu Bar.  To access the Menu Bar, press Control-Option-M. 
    Go to Apple Menu > About This Mac.  This will open up another window.  Use Control-Option-Right Arrow until you hear 'Version'.  If you purchased it brand new from Apple within the last six month, more than likely you have Mavericks.

    The  'Commands Help' Voiceover Menu. Control-Option-H-H.  (hit H twice)  is my best friend.  It's a searchable VoiceOver Menu with most of the VoiceOver command.  Example:  You are looking for the 'Read Current Paragraph' keyboard command.   Press Control-Option-H-H and then type Paragraph.  It will then bring up all the commands with the word paragraph.  I believe there are three.   
    As from the Trackpad Commands, I've copied and pasted below from Appendix A: Commands and Gestures

    To customize other gestures by assigning VoiceOver commands to them, use the Trackpad Commander.

    I wiped my ipod classic and then my computer crashed, so i no longer have the songs i purchsed from itunes on my ipod or computer! I have a new computer now with itunes installed, can I get the songs purchased previously from itunes somehow?

    Yes, you can!(:
    STEP 1: Open iTunes
    STEP 2: Navigate to the "iTunes Store". It can be found under the "STORE" tab.
    STEP 3: On the right side of the store there should be a "Quick Links" Section. Click on the "Purchased" link.
    STEP 4: Navigate to the "Music" tab and click on "All Songs". Then at the bottom of the screen there will be a button that says "Download All". Click the button and your songs will be begin downloading!
    NOTE: This will only work with songs that you bought from the iTunes store, if you imported them from a CD, you will have to do it again.
    NOTE: You can also do this with Apps, Movies, TV Shows, and Books.
    NOTE: You may have to sign in with your Apple ID to verify the download.
    Hope this helped! Enjoy your music!(:

  • How can I change the default pdf reader from the installed (but not yet registered) Adobe Acrobat 9 Pro to Adobe Reader XI?

    How can I change the default pdf reader from the installed (but not yet registered) Adobe Acrobat 9 Pro to Adobe Reader XI? I'm having some hiccups getting Adobe to register the software, but since I set it as the default .pdf reader during setup, things try (and fail) to open in the as yet unregistered software. How can I change it temporariiy to the Acrobat Reader XI that I have installed?

    Anubha,
    It worked! Thank you so much.
    I'd opened file with the 'Open with' feature then clicking Adobe Reader,
    but that didn't do it. When I used 'Open with', then 'Choose default
    program...', it worked like a charm.
    Again, thank you!
