I want to use 2 differents programs to acces a PCI-6036E at the same time,is it possible?

LabViewApplication1.exe use:
analog output 1
analog input 1.
LabViewApplication2.exe use:
analog output 2
analog input 2
digital output 1.

Hello,
The way it looks like you are describing, no, it would not be possible. Think of the Analog input and Analog output circuitry as a resource. All analog input channels must be configured and used within the same task. You must clear that task in order to add/change the channels used. The same is true for analog output.
However, you might not have this limitation if you are doing acquiring/generating single-point updates. (The "task" is cleared as soon as the point is retrieved/output.) So one program could acquire one point from channel 1 and then the other program could acquire one point from channel 2. The same would be true for analog output and digital I/O.
You should be aware that The Traditional NI-DAQ driver is only single-threaded. So,
though you may be able to have two processes running "simultaneously" that both have access to the driver. They had better not try to both initiate a function call at the exact same time or you will get an error. (So to insure reliability, you would have to manage your code such that this doesn't happen.)

  • If I have 2 tv's and each their own apple tv can I display the same program to them from my macbook at the same time?

    If I have 2 tv's and each their own apple tv can I display the same program to them from my macbook at the same time?
    for instance Keynote?

    Welcome to the Apple community.
    The Apple TV cannot display keynote presentations or websites from the computer. It can display them via mirroring from the iPad 2 or better or the iPhone 4S.
    You cannot AirPlay to 2 Apple TV 2's at the same time from an iOS device. You can watch the same video, TV show or listen to the same music from your iTunes library on multiple Apple TV's at the same time.

  • Can I pair and use more than one set of bluetooth speakers at the same time on my ipod touch 4.0

    can I pair and use more than one set of bluetooth speakers at the same time on my ipod touch 4.0 or Iphone 4s or Ipad 2?

    You can only connect to one device at a time using Bluetooth, See article below for more information.
    http://support.apple.com/kb/ht1664
    While your iOS device can maintain multiple pairing records, it can only connect to one headset or hands-free device at a time. This prevents your iOS device from sending your data to the wrong Bluetooth accessory.

  • I want to disable "restore previous session" and enable "History record" at the same time.

    I want to disable "restore previous session" and enable "History record" at the same time.
    Because I don't want others to access my account such as "Gmail", "Facebook". But I want firefox to record my browsing history.
    What should I do?

    I managed to remove the "Restore Previous Session" button from the home page by changing my default home page with this : www.google.com/firefox/ (the default home page from the previous versions of Firefox). It worked for me, I hope it works for you too.

  • Can I use HP Pro 8600 with usb and wireless at the same time

    Can I use HP Pro 8600 with usb and wireless at the same time?  Sometimes I cannot get the wireless to work, it seems to be my laptop.  It would be nice if I could use the usb, but it doesn't work.  What should / can I do, if anything?
    Sam

    Hi,
    Same physical printer but when connecting to SAME computer using both USB and wireless it becomes two (logical) printers. Probably your default prnter is the wireless one, you have to select the right printer before print .

  • Can you play the guitar program and also run a keyboard at the same time using seperate outputs for both?

    I wanted to be able to play live on my electric guitar using mainstage and my keyboard player to use mainstage on the keyboard can this be done using the mainstage 2 on this computer?  Also if this can be done can you send the keyboard output and the guitar output seperatly to be able to be in different channels in the PA system?

    Short answer: YES (but you will need to carefully consider how you organise your Patches with Guitar and Keys combinations, so that you both get the correct sounds at the same time)

    Yes, ideally using a multi-output audio interface. edit (with 2 outs for the guitar, and 2 for keys... you might also want another 2 pairs for monitoring)

  • Possible to use both optical out AND regular line out at the same time?

    I currently have my computer speakers (logitech z560) hooked up to the mac pro via regular stereo jack in the back. I have an extra receiver that I would love to hook in to supply me with some needed sound for movie watching and what-not.. Is there a way to enable both line out - digital and line out at the same time?

    You can set DVD Player's "Audio output" to "Digital Out" in its "Disc Setup" preference, while other applications use Line Out.
    You could use a splitter on Line Out to feed your current speakers, and analog Line In on your receiver. When you want sound to both systems, set the receiver to Line In. When you want to watch DVDs, set it to Digital In. This will give you surround sound if the DVD has multichannel sound, and the receiver supports more than two channels.
    If you really want the same output on the Mac Pro Line Out, and Digital Out, you can use the "Auxiliary Device Output" effect in Audio Hijack Pro
    <http://www.rogueamoeba.com/audiohijackpro/>
    It will not support more than two-channel audio.

  • Acces both network interfaces at the same time

    Hello community,
    I have a little problem that I cant seem to solve.
    My iMac is connected wired to a network wich has all ports blocked except the the neccecery ports wich are required for the company network.
    Besides that, there is also an open wifi network wich has no ports blocked. In order for iMessage to work properly, I must use the wifi network, however when wifi is activated and is set as the first network, work related software dont work since they need a connection to the secure network.
    So my question is:
    Is there any way to acces both networks at the same time ?
    Or let one app use one network connection and another app use wifi.
    Thanks a lot!

    The behavior you describe sounds quite unusual. Can you provide a screenshot of the window you are attempting to move?
    If you are describing the process of moving a tab from one Internet Explorer window to another on a separate screen, you do not need to drag the tab to the taskbar icon when transitioning between
    windows, you can drag the tab directly from the row of tabs on one window to the other.
    If you are clicking a button in the window bar that minimizes multiple windows simultaneously, you may be describing a third party window management application (NVIDIA nView, AMD HYDRAVISION).

  • Can I use both ePrint and AirPrint on an HP4630 at the same time

    I have an HP4630 printer that I wish to use with an iPad and Mac Notebook (PowerPC running OS X 10.5.8) and want to know if I can run AirPrint for iPad and ePrint for Mac Notebook at the sametime.
    I understand that Mac Notebook can not connect to the printer over the network because it is not capable of running OS X 10.6 and above.
    I appreciate your help.
    This question was solved.

    Hello Chesher5,
    Welcome to the HP Support Forums!
    Regarding the inquiry into ePrint and AirPrint for the Officejet 4630, yes they can be both used at the same time. They are completely separate means of printing. Both require a network connection though.
    If you have any problems setting up or using either, please let me know and I'll do my best to assist.

  • Using two Desktop Macs with HP LP2475w monitor at the same time?

    Hello,
    I was curious to know if anyone knows if I can use this monitor with a 2010 MAC and a G4 MAC from about 10 years ago at the same time? There are many ports on the HP monitor that can possibley be used simataneously? I am worried this will damage the video card on the MAC(s) that I have. I have a feeling I have to switch one off and use the them one at a time.
    The reason I am asking is that I have an old Nikon Coolscan 4000 fim scanner and Nikon for some crap reason has never updated their Nikon software for the INTEL Macs. (oh... they think film is dead and no one has 1000's of slides) but the scanner will work on my G4 Mac. I don't want to continoulsy turn off one MAC and turn on the other.
    Thank you

    Here's the Wiki definition of a "KVM Switch".  But briefly, yes, you can switch among computers use a common keyboard, video, and mouse on the fly, hence the name "KVM".  2-port KVM's are for two systems but KVMs do exist to handle more than 2 systems (at a higher cost of course).
    I would google searches for "DVI KVM" and/or "Displayport KVM".
    If I were doing this at this I would probably be looking for DVI's as opposed to Displayport not for any real technical reasons but only because on my mac I have mini-displayports and a DVI port so I am currently familiar with the kinds of adaptors, cables, etc. involved.  I haven't needed to deal with a full sized displayport but I imagine there's suitable cables and adapters for that too.  I suspect the deciding factor would come down to cost as to which kind to use.

  • Can I use BOTH Verizon DSL Wireless AND DISHnet Wireless at the same time?

    Waiting for Dishnet contract to die and rot away but about 2 months to go.  Want to get with Verison Standard DSL Wireless as no data cap tho slower.
    I can just wait till Dishnet dies and keep bumping into data caps with the Dish service OR can I get the DSL setup and use one connex for the iMac and one for the iPad without any conflicts?
    I am so ignorant of technology that I see a Swing-a-Way hand crank can opener as a marvel of industrial magic,....so please talk simple words to me, :-) 
    Thanks
    DH

    Sign up for the fastest DSL package that you can. Even if the overall speed is slower, the fact that you won't be going over a satellite connection anymore should make the Internet *that* much faster. The Wireless Gateway should come included.
    You can use both services at once, although note that determining how you plan to use both at the same time is going to be another story. Some people use Dual WAN routers (as in, routers that accept two Internet connections and can balance between the two). Others will use the connections separately, by moving devices between the two connections as needed.

  • Can we use both 0FI_AP_3 and 0FI_AP_4 for Delta Loads at the same time.....

    Hi Gurus:
    Currently my company uses 0FI_AP_3 for some A/P reporting. It has been heavily customized & uses Delta loading. However, SAP recommends the use of "0FI_AP_4" for A/P data fro delta loads. I was able to Activate 0FI_AP_4 as well & do some Full Loads in Dev/Test boxes. Question is whether I can use both the extractors for "Delta" loads at the same time......? If there are any issue, what is the issue and how ccan I resolve it? Is the use of only one extractor recommended......??
    Please let me know as this impacts a lot of my development....! Thanks....
    Best...... ShruMaa
    PS:  I had posted this in "BI Extractors" forum but there has been no response......  Hope to get some response.......!  Thanks

    Hi,
    I would recommend you to use 0FI_AP_4 rather using both, particularly for many reasons -
    1. DS: 0FI_AP_4  replaces DataSource 0FI_AP_3 and still uses the same extraction structure. For more details refer to the OSS note 410797.
    2. You can run the 0FI_AP_4 independent of any other FI datasources like 0FI_AR_4 and 0FI_GL_4 or even 0FI_GL_14. For more details refer to the OSS note: 551044.
    3. Map the 0FI_AP_4 to DSO: 0FIAP_O03 (or create a Z one as per your requirement).
    4. Load the same to a InfoCube (0FIAP_C03).
    Hope this helps.
    Thanks.
