Capture camera IMAQ via DAQmx trigger operation

• DAQmx trigger

  I'm relativley new to labview and I have a problem, try to configure the trigger with DAQmx

  Im am using NI 6210 to acquire data of probe of HAVE - what Im I'm wanting to do is aquire data whenever the proxistor is triggered since my digital input.

  So what I am asking is to capture 1 cycle of data and save data on each cycle to be used at a later date to remove some samples at a specified time.

  I installed a test (VI attached) that, for the moment, uses through Boolean to see when the proxistor goes high and start this accurs task and the data entered and the task is stopped when the proxistor is low. This seems to work ok from what I was told that is - this isn't a very good way of timing and I see that captured samples are not the same each cycle so I need to look at another way to capture 1 full cycle of dat using the DAQmx trigger for the aquistion. I have been thorugh the examples NOR but these cant find a way to implement the trigger for what I need. I also read that this series of card does not re - trigger that I need to implement?

  Any help/advice would be greatly appreciated.

  Hi David,

  Sorry for the late reply-

  Yes the VI you provided helped me a lot and is a good start for me to help me do what I have to do.

  Thanks for your help

• Several synchronization AO-DO-DI via DAQmx, external trigger devices

  Having trouble getting the digital input to trigger analog output unit.

  I have 2 AO cards (although I'm testing only with 1 device AO)

  2 cards DIO - using one for output, one for input

  All 4 cards are connected via a RTSI cable, and the cable is correctly condfigured in MAX, all 4 devices added to the cable.

  I consider the AO the 'master' unit map In this test, I plead for a finite number of samples, and I'm outside triggering map AO.

  As you can see, iI uses Signal export, export the AO and AO Start Trigger sample clock to DIO cards.

  I'm using Labview 2012 on PC Windows 7.

  The digital output is waiting for the AO trigger and appears off the coast of the AO sample clock synchronizing.

  The digital input expires if I only fire at the time, so he does not expect relaxation.

  any ideas?  I tried all kinds of combinations.

  

  

  Never mind!  I solved the problem with digital input without waiting for the external trigger.

  I just had to set the time-out waiting-1, so that he would never expire, and so he will wait for the trigger.

• Can I trigger operations of first transit via firewire?

  I read a lot about the onset of external units such as a DV deck, etc. of Adobe Premiere, but I want to do the opposite, and I was wondering if anyone had tried?  I would like to connect a DSR-45 and be able to trigger Adobe Premiere when I trigger the bridge...  So if I start recording of the bridge, the software will start...

  Thoughts?

  It was a problem of driver... follow these steps and it worked great!

  In Windows: Click on start-> Control Panel-> system-> device (to the top top-left) Manager, or simply click on the Start button and the search for "Device Manager."

  Pivoting toward the bottom of the entry for the ' controllers Host Bus IEEE 1394 and do right click on the item that is revealed (depend on the manufacturer of your computer/card).» Select "Update driver software."

  Click on the 'Browse my computer for driver software', and then the "Let me pick from a list" button.

  In the list of drivers, select one that has "(legacy)" at the end; Click Next, and then close all dialog boxes.

• DAQmx Trigger: Error 2200077

  Hello

  I am trying to create a program to trigger a hammer signal, using a USB-6211 card and 4 analog inputs (via 1 DAQmx create channel HAVE voltage to the hammer and 3 others at the exit of the accelerometer). Having as a basis for some examples of LabView as "Acq Cont & voltage chart ' and 'Impact Test (DAQmx) [.vi SVXMPL_Impact Test (DAQmx)]', I built my program, but it does not work.

  If I don't put the relaxation and the task to start, my programme without any problem (in this case I use 4 DAQmx create channel HAVE tension, a DAQ Timing, linked to the DAQmx Read located on the loop). But when I add the trigger (start analog Edge) out of the loop, so that between the time the DAQmx Read, error-200077 apears and DAQmx. This same error apears too when I try to run the sample of "Cont Acq & voltage graph" (even if I change the sample rate and the number of samples, the error is still the same). The error-200431 apears when I try to launch the second example ("Impact Test (DAQmx) [SVXMPL_Impact Test (DAQmx) .vi]), but in this case probably the DAQ card is not suitable to run this program.

  When I add a task to start before the loop (where is located the DAQmx Read function) on my program without the shutter button, the error-200278 appears. And if I add the trigger and Start Task, just the apperas-200077 error function. However, the startup task is not bothering me as much as the trigger, because when I do not use the trigger on the example "Acq Cont & chart tension" and the task of beginning is always there, this program runs normally. In this case the problem is probably on my prgram and not on my data acquisition card.

  I just want to know if my card cannot run this trigger function (early analog Edge) or if there is something else, because it's strange how a relatively simple example can be run using my data acquisition card.

  Thank you

  Hi, FCB,.

  The USB-6211 can only be released digitally.

• How to export via the trigger star pxi to several dvices

  Hello

  I have huge problems to do this work and free time to try rarely. Joined my unfinished VI (SyncTrig - Test.vi) who needs to synchronize 9 x PXI-4472 & 1 x PXI-6713 on PXI-1006 chassis (made up of bus 3 x 6 slots). Master ST in the #2 Groove is DSA (PXI-4472), the rest 8 x DSA are inserted in slot #3-#10, and MIO (PXI-6713) is in slot #11. I need MIO to generate signals of x AO 2 (ao0:1 or ao6:7) of arbitrary length. DSAS acquire 72 x channels HAVE simultaneously until the last pair of samples AO is triggered (AO and I work at the same pace).

  I understand there are 2 ways to cynchronize a all these devices - to use reference clock 10 MHz from backplane, or Star trigger bus. Trigger the beginning of ST control is supposed to start all 10 devices. I couldn't do the 'references', examples and I managed to do the "StarTrigger" example works with 2 devices so I decided to stay with the latter. Of course, I hardly expect export usable for the PXI-6713 SampleClock and we hope to get help on this forum.

  Here are my 3 questions/dilemmas:

  1 grouping DSAS more in a single task & export clock via ST each

  I've separated the master of ST in the UpperTask export SampleClockTimebase via the bus ST and StartTrigger through the spine. The rest of the DSA are grouped in a single MiddleTask since NEITHER-DAQmx makes it easier for this type of devices PXI. In VI, UpperTask exports in a single PXI location.

  Is it possible to format the string to export the clock via ST to the multiple (all the) SHAS so they can all receive it grouped together in the unique MiddleTask? Or should I use a loop for export the time base clock 8 times and feed it 8 times for all slots #3-10?

  Please be specific.

  2 synchronization MIO with DSA master ST via bus from ST

  How can I use the TimingNode to implement SampleClockTimebase division, so that the PXI-6713 can use it in the #11 slot (LowerTask)? If this is not possible via the ST bus, can someone please show me what TimingNode (s) to use to export usable St master clock and get to MIO to synchronize the HAVE and AO closely?

  3 triggers of PXI chassis

  I left 2-7 as 'Dynamics' triggers to be available for NOR-DAQmx. Is it enough for the configuration shown above, from PXI devices occupy 2 of 3 independent buses in PXI-1006?

  BTW, I tried a different approach (SyncTrig - No. AO.vi), but the mistake of resting LowerTask just after his TimingNode power.

  Ladies and gentlemen, I hope power affirmative responses because the documentation is completely absent on synchronization PXI DAQmx and are completely dependent on WEB resources.

  Thank you in advance,

• A99 with SB900 off camera. What wireless trigger buy?

  Hello

  I just move slowly through the world of the digital SLR. I have an A99 and a friend gave me a SB900 flash. I would like to try off-camera Flash so was going to pruchase a Pocket Wizard mini configuration.

  Does anyone have experience with a SB900 and a working wireless A99?

  In addition, when it is mounted on the camera the TTL parameter is not firing the flash so I use just manual. Would it be a problem of no compatibility Vs nikon Sony?

  Any help much appreciated, has soon!

  A wireless, such as Pocket Wizard radio trigger can be mounted on the claw of the appliance and trigger a flash off-camera. You can refer to the operating instructions of the wizard of pocket for more information.

  The measurement of your camera system and the flash is not compatible. Indeed, you may have to resort to manual settings when you mount the flash directly on the camera body.

• Capture camera mini DVD?

  I have a client with a dvd of the mini of Panasonic and Sony cameras.  I was able to copy the images and rename the .vob to .mpg and edit files, no problems.  About 15 of the 50 disks have problems.  I'm racking my brain on workarounds to capture images.  Some of the discs will play on the cameras they record to.  I tried to take the records directly to my computer from the camera to a stand-alone dvd recorder with a bit of luck.  Is it possible to capture video via camcorder using the USB on my computer?  Would this work if I had a drop cable and used the av cables into my computer with first?  Other creative ideas?  I think this media is a bit dodgy and happy it seems to be obsolete.

  Thank you

  Lisa,

  I'm sorry that everything is not fine. The trick with the help of miniDV Tape cameras will be, do they Pass through? Once, it was common. Then, it seems that some European countries added VAT to those, determine a rate higher applied, as they were basically "decks," mfgrs Yes Ribbon. has started to disable the transmission of video description on the Euro models to keep their price-points online. Then, many have stopped just put this tour in their cameras. So, it's really one - situation "it depends." If your have pass through, which should work fine. Don't forget, you need to place the miniDV camera in the appropriate mode (see manuals), and you will have the remote, because that goes only on FW and source machine is hooked to the camera via composite cables. Yet, we can simply press Play, and then click Capture in quick succession. I do similar with my DVR to my deck-D. I have remote DVR in my left hand and my mouse in my right. At most, I capture maybe 5 empty frames. Learn to juggle and be ambidextrous! After a bit of capture in this way, I can almost drink a coffee with my left hand.

  Good luck and I hope that your camera has transmission capabilities.

• Unable to update Apple software such as iTunes, Safari, camera RAW via AppStore mac

  I could not update Apple software such as itunes, safari, camera RAW... etc via the mac app store.  Whenever I click on update, it will show 'installed' within seconds without actually updating the software and the same installation notification will appear again in the app store.

  I can update some of the apps manually through the apple website and download the update file. However, I wonder if there is a remedy to this problem without having to manually update each time.

  This problem is only limited to the Apple software, 3rd party applications I've downloaded from the app store can be updated without problems.

  This problem started when I Yosemite, and I've since updated to El Capitan (without a clean install) and the problem persists...

  I'd appreciate any help to solve this problem. Thanks in advance!

• Trident video capture card connected via USB 2 not working not properly under XP

  I use a Trident card connected via USB 2.0 video capture and I had a weird behavior:

  -sometimes not detected (not included in the list of devices)

  -sometimes not recognized (unknown device)

  -sometimes not start (Code 10)

  -sometimes works very well

  I used a USB Tracker to study the issue and found out that the usbehci driver is not able to activate the USB port.

  The message sequence is as follows (when it works):

  Get the status of the Port (4) - success

  Serial Port (4) feature, Reset - success

  Get the status of the Port (4) - success

  | - Port is enabled

  This is when it does not work:

  Get the status of the Port (4) - success

  Serial Port (4) feature, Reset - success

  Get the status of the Port (4) - success

  | - Port is NOT enabled

  Function Clear (4) Port, connect to state change - success

  Get the status of the Port (4) - success

  Serial Port (4) feature, reset the change - success

  I have more tracks, but I don't know if this is the right place to post.

• Creating a workspace via a trigger?

  Hi all
  
  I am new to the use of Workspace Manager and Oracle in a development environment and I am working on a development where multiple workspaces must be created whenever a developer wants to make a change to the database via a Java application.
  
  My ultimate goal is a workspace to create before a release is made.
  Is it possible in the form of a trigger that will allow the gaming tables, a name of workspace (possibly using the date and the OS developers username) and then commit changes disable versioning tables (or will trigger this part are part of an update after)?
  
  If not, this could be done using a PL/SQL Package or is it not a very wise thing to do at all?
  
  Concerning
  
  Mark

  Hi Mark,

  Take note of what I wrote in the first reply in this thread. Whenever you allow privileges to ADMINISTRATOR of your application, the creation of workspaces, etc., there is always a risk associated with that.

  But it's how grant you these privileges:

  RUN DBMS_WM. GrantSystemPriv ('ACCESS_ANY_WORKSPACE, MERGE_ANY_WORKSPACE,)
  CREATE_ANY_WORKSPACE, REMOVE_ANY_WORKSPACE, ROLLBACK_ANY_WORKSPACE',
  'wm_developer', 'YES');

  I will try to take a shot at your problem.

  A possible solution using OWM would be this:

  Once, to create a workspace, call it something meaningful, that this workspace will represent your current version.

  In the application, to make change only in the workspace, you can just use SQL:
  RUN DBMS_WM. CreateWorkspace ("myReleaseR123");

  at this point your session working within the workspace

  You perform the change of workspace LIVE or any other:

  RUN DBMS_WM. GotoWorkspace ("LIVE");

  And the final score, after having made all these changes within the workspace R123, you are ready to click a button and "committing" these changes in the LIVE of your data version: just to make this call:

  RUN DBMS_WM. MergeWorkspace ("myReleaseR123");

  As you can see it your application should not create workspaces alone, in this way, you don't have a lot of control and flexbility.

  I don't want to get into too much detail, but simply take a part of the tasks of the admin application, it is a better design in this way.

  I hope it's good for your beginning with OWM.
