Use of ni6711

I need generate two signal, the first are an trigger signal, 10 V amplitude, pulse width 10 micro-seconds
and two possible frequency (user discretion) 500 Hz and 3200 Hz.
The second signal is an triangular wave, amplitude between 0/-4V, this signal must be in phase with the first, and its frequency must be the frequency of first signal multiplied for 5
(for example if the trigger signal is 3200 Hz, the second signal must be 16000 Hz, in phase with the first signal).
Is it possible generate these signals with two analog output of Ni6711?
Can I generate contemporary of the two signal above
two TTL signal, one trigger 0,4Hz/70mS pulse width and one square wave 2 KHz means the two counter timer of Ni6711?
Can I use Visual Basic to manage Ni6711
card for this work means an DLL?
Tanks

Hello;
Yes, you can do that, but to generate the triggered TTL pulse train, you will need to use a 660x board together with the 6711.
I'm saying that because the counters of the 6711 board, don't have triggering capabilitie; and the counters of the 660x do.
As you need synchronization, you will need to connect both boards together by using the RTSI cable. Once that is hooked up, you can definitely use Visual Basic and NI-DAQ dll function calls to accomplish that.
Hope this helps.

  • Use of NI6711 card.

    How I have asked before, i need generate four signal:
    1) One sine- wave signal from 0 to -4 Volt, and frequency less than 100 KHz.
    2) One trigger signal, amplitude 10 V, frequency 3200 Hz and pulse- width from 1 to 10 micro Seconds.
    3) Two trigger signal, amplitude 5V, frequency 0.4 Hz and pulse- width 20/70 mS in opposite phase.
    4) Two square wave signal amplitude 5V, frequency 2 KHz, in opposite phase.
    For this application I have thought an Ni6711, used at follow mode:
    One of four analog output to generate the first signal.
    One other of three free analog output to generate the second signal.
    Two of 8 digital I/O for generate the signal at the third point.
    The counter/timers output to generate the two signal at the point four.
    But Felipe in his answer (tanks Felipe) sayng that regarding my third signal requirement,
    I need to have two more counters to do that. He saying that because, the digital lines
    of that board don't have strobed, operation capability.
    My new ask is that:
    Can I use for generate the signal at the third point the two remainder free analog output?
    in stead of two of 8 digital I/O?
    Tanks.

    Hello;
    You can do that. As the frequency of the pulse train you need is not high, you can rely on the Analog Output channels to accomplish that. That is a good idea.

  • I cannot get innterrupts from an NI6711 analog output board

    Hi everybody,
    I am using a NI6711 AO board and a NI 6052 MIO board with VxWorks and DDK.
    I tried Aoex5.cpp and used IRQ pin 0 and  kInterrupt_Output_PolarityActive_Low as
    described in the PCI E Series Register level manual since this board
    has also a mite chip.
    The number of updates is larger than the FIFO size, so that an FIFO interrupt has to be asserted. The settings work fine with an E Series board (NI 6052) but I cannot get any
    interrupts on a NI6711 board.
    From some posts to the forum I assume that some people got IRQs from a 6711 or similar 6733 board.  How did you get them?
    Is there a HW problem with the NI6711? It  works fine on a Windows computer and LabView examples.  I suppose the Labview driver uses DMA instead of board interrupts. Dose the Labview test really tell me something about the IRQs?
    Can anybody help? Thanks
    Heike

    Hi Heike,
    I hope this will help you.
    I send you two screenshot - one of LabView and one of the DAQmx C Reference help to see the function for cpp.
    You can find the "DAQmx C Reference help" on your system:

  • Use of NI6040E

    Excuse me for my perseverance and My bad english but I looking for a better solution before buy.
    I have now two questions.
    First question:
    How I have said before, i need generate four signal:
    1) One sine- wave signal from 0 to -4 Volt, and frequency less than 100 KHz.
    2) One trigger signal, amplitude 10 V, frequency 3200 Hz and pulse- width from 1 to 10 micro Seconds.
    3) Two trigger signal, amplitude 5V, frequency 0.4 Hz and pulse- width 20/70 mS in opposite phase.
    4) Two square wave signal amplitude 5V, frequency 2 KHz, in opposite phase.
    For this application I have thought an Ni6711 and apparently I don't seeing a lot of
    problem, but supposing I don't need at the point 3 and 4 that the signal are in differential mode,
    but in
    single mode (not in opposite phase) then my new situation is that:
    1) One sine- wave signal from 0 to -4 Volt, and frequency less than 100 KHz.
    2) One trigger signal, amplitude 10 V, frequency 3200 Hz and pulse- width from 1 to 10 micro Seconds.
    3) ONE trigger signal, amplitude 5V, frequency 0.4 Hz and pulse- width 20/70 mS.
    4) ONE square wave signal amplitude 5V, frequency 2 KHz.
    Can I use One NI6040E in stead of Ni6711 as shown below?
    One of two analog output to generate the first signal.
    Another of two free analog output to generate the second signal.
    ONE of two counter/timers output for generate the signal at the third point.
    Another of two counter/timers output to generate the signal at the point four.
    The vantage of this choice is that with this card I have up to 16 analog Input ready for further use.
    It is right?
    Second question:
    I already have used Ni products, in particular, DIO96 and GPIB, I have used this card with Visual Basic, I control
    these cards means GPIB-32.DLL and NIDAQ32.DLL
    Can I use a similar metod to accede at NI6040E or Ni6711?
    If not, Can I use however Visual Basic with these cards?
    Many Tanks.

    Hello;
    Regarding your first question, the answer is Yes. You can use the PCI-6040E to accomplish that task.
    Regarding your second question. You definitely can use Visual Basic to program the board. When you install NI-DAQ (the driver for the DAQ boards), you have the option to install the support files for Visual Basic. IF you do so, a Visual Basic example folder will be created at C:\Program Files\National Instrumenst\NI-DAQ\examples\VBasic. You can use those examples as start point for your application.
    Hope this helps.

  • Multiple channel waveform output using a 6711 board

    Hi,
    I am writing a driver for VxWorks RTOS based on the DDK for a NI6711
    analog output board.  I cannot find an example for timed waveform
    output on  more than one channel. I adopted aoex3.cpp (which works
    fine under VxWorks for one channel) to operate also multiple channels.
    I set all DACs to timed and wrote to the waveform generation register
    once for each channel. I tried several settings  for the number
    of  channels:
        theSTC->AO_Mode_1.writeAO_Multiple_Channels(1);
        theSTC->AO_Output_Control.writeAO_Number_Of_Channe​ls(iNumChans);
    None of the settings of  iNumChans results in the correct output  on all selected channels.
    The comedi driver uses the settings
       theSTC->AO_Mode_1.writeAO_Multiple_Channels(0);
        theSTC->AO_Output_Control.writeAO_Number_Of_Channe​ls(0); But that does not work either
    Any help would be very much appreciated.

  • How to install NI6711 (PCI) & MIO-16X (ISA) on the same PC?

    NI6711 & MIO-16X work with two differents versions of NI-DAQ: Each version can detect only one DAQcard. What the solution to install them on the same PC?

    I know that the pci-6711 is supported since nidaq 6.5 and that since that version the at-mio-16x is no longer supported. Thus, there is no way to get them to install in the same computer. Either you must install them in different computers, or you should get a new board which performs the same operations of the mio-16x. There is a huge variety of E series boards which perform operations much better than that legacy board. Maybe you can get it to exchange with your Sales Rep.
    Hope this information is useful.

  • How can multiple family members use one account?

    My children have iphones, ipads, ipods and mac books, my problem is how do you use home sharing with the devices and not get each others data.  My Husband just added his iphone to the account and got all of my daughters contacts.  I understand they could have there own accounts but if i buy music on itunes and both children want the same song, I don't feel i should have to pay for it twice.  Is there away we can have home sharing on the devices and they can pick and choose what they want? and is this icloud going to make it harder to keep their devices seperate?

  • Iphoto crashing after using mini-dvi to video adapter

    Hi, IPhoto on my Macbook is crashing. I can open it, then as soon as I scroll down it locks up and I have to force quit.
    This started happening right after I used a Mini-DVI to Video Adapter cable to hook my macbook up to my TV. The adapter/s-video connection worked and I was able to see the video on the tv. But iphoto immediately locked up the computer when I went to slide show and now it locks every time I open it.
    Any ideas?
    Thank you:)
    Dorothy

    It means that the issue resides in your existing Library.
    Option 1
    Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
    If that fails:
    Option 2
    Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords, faces and places back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

  • Using SQVI to generate report of open and released delivery schedule lines

    All,
    I'm using SQVI  to generate an excel spreadsheet for some buyers to show open released schedule lines because they are a 1 line item per scheduling agreement company.
    I used the logical database MEPOLDB instead of a table joint and pulled fields from EKKO(vendor, SA #,&purchasing group), EKPO(Material Number), EKEH(schedule line type), and EKET(delivery date, scheduled qty,previous qty).
    Does this sound like I'll get the results I want on paper as long as I use the right selection criteria, because the report I'm getting isn't quite what I expect? I am unable to identify which lines are authorized to ship vs. trade-off zone, planning, etc. in the report thus far.

    Hi Mark,
                 I have faced same requirement. I am not sure about transporting to TST and PROD. I done by this way.
    After generating SQVI program in DEV , I assigned that program  to a transaction and tested in DEV. Later i have regenarated SQVI in Production. then I assigned the generated Program to same transaction in DEV. And transported the Tcode assignment of program to Production..
    About authorization , if its not sensitive report, BASIS can restrict at transaction level.

  • Using Mini DVI to VGA adapter on MacBook

    I bought the adapter from Apple & hooked up my LCD monitor to the MacBook, but the video I get on the monitor is different that on my laptop. It has an old screen background & the dock but nothing on my desktop shows up. Also, when I'm plugged to the monitor, my dock disappears on the laptop screen. Is there some setting I need to change? It worked fine with my G4 PowerBook.
    Thanks for any help....
    MacBook   Mac OS X (10.4.6)  

    i use the mini dvi-vga adapter in my classroom almost everyday. It sounds like your new monitor is running as a side by side monitor to your display instead of a "replacement" display.
    To get your projector/monitor to basically show whatever is on your macbook screen once you've hooked up press F7....this should make your projector/monitory become your display with your dock & all of your desktop stuff. Your new monitor will completely mirror your display.
    THis should do what you're looking for.

  • Using mini-DVI to VGA adapter to Samsung display

    I have 2009 late model of mac mini, The text on display looks washed out, not clear or sharp at all from day one, I thought it was the old model of monitor, tried the same cable to another monitor on another computer, SAME. so I thought the problem could be the cable or adapter.
    It's hard for me to believe is the signal from computer. I'm using VGA adapter made by Dynex bought from Best Buy.
    Anybody has suggestions?? Thanks

    Yeah, My old Samsung is lcd synmaster 17", bought many years ago at around $1000. Crazy, crazy price looked back. It's fine when I used it on the retired old Dell. It must be the adapter, trying not to buy another VGA adapter, could not image my next lcd will use one, anyway.
    This cable has only 14 pins vs 15 pins on the other cable, not sure if it matters?? Or if Safari has anything to do with it??
    Thank for you reply...

  • Using S-Video w/ the Mini DVI to Video Adapter

    I just purchased a MacBook last week and I also purchased a Mini DVI to Video adapter for it so I can use the built-in DVD player to watch movies on my TV. I have a composite to composite cable and that worked fine when I connected the cable between the Mini DVI to Video Adapter and my TV. However, when I tried to use a S-Video cable and connected that between the Mini DVI to Video Adapter and my TV; then I got no picture at all. All I saw on the TV was a picture of the MAC desktop w/o the dock and the movie or nothing else played at all.
    Is the composite connection a better connection for the MAC, or, are there some settings I need to work with on the MAC to get the S-Video connection to work?

    I managed to figure this one out, by fluke. The MacBook has to be powered on and ready for user input prior to connecting the mini DVI to video adapter with the s video already connected to it, and to the TV. Once I did it this way, it worked fine. I just thought I'd share this.

  • Using a mini-DVI to video adapter

    I have connected the video adapter and everything works fine. I use the internet for my video source and I was just wondering, is it possible to have video playing fullscreen on the tv and have another window open on my desktop that I can work with without disrupting the video from the browser? Every time I watch something I am unable to work on my computer while the video is playing.

    As far as I know, you can't go full screen on one monitor without it interfering with the other. I believe this would require a second video card, which isn't possible for a MacBook.
