• Using instrumented hammer model PCB 086D 50 with the NI9234 module and chassis OR cDAQ 9188

  Hi all

  I need to try to shock with a PCB 086D 50 instrumented hammer hammer. I use the chassis OR cDAQ-9188 with the NI9205 and NI9234 modules. The hammer is connected to the NI9234 and accelerometers are connected to NI9205.

  When I test the modules in SignalExpress I get very good results for the dog, but the accelerometers are ok. Also, if I am controlled the hammer OR Max where I have the option to activate the IEPE the result is ok. In SignalExpress, I couldn't find the option to activate IEPE.

  I have no experience using software, but I started to learn. Does that mean that I need to program the system for my setup in LabVIEW? Also, the installer of the equipment makes sense, the modules that I plugged on the cDAQ can be used simultaneously? Should I have the additional device in order to use the hammer with cDAQ 9188?

  Thank you very much

  You can enable IEPE in SignalExpress. Here is a configuration for a single power hammer and three accelerometers a 9234-related.

  

  You don't mention the model for accelerometers. They are also the IEPE sensors? If so, have what conditioning of signals you added before the 9205?

  The Assistant Sound and Vibration (built on SignalExpress) contains an example of Impact Test. The Sound and Vibration Toolkit comes with a sample project for the impact test. With free evaluation period, go ahead and look at how one of these examples is implementing the configuration and the triggered acquisition.

• buffer size and sync with the cDAQ 9188 problems and Visual Basic

  Hi all, I have a cDAQ-9188 with 9235 for quarter bridge straing caliber acquisition module.

  I would appreciate help to understand how synchronization and buffer.

  I do not use LabView: I'm developing in Visual Basic, Visual Studio 2010.

  I developed my app of the NI AcqStrainSample example. What I found in the order is:

  -CreateStrainGageChannel

  -ConfigureSampleClock

  -create an AnalogMultiChannelReader

  and

  -Start the task

  There is a timer in the VB application, once the task begun, that triggers the playback feature. This function uses:

  -AnalogMultiChannelReader.ReadWaveform (- 1).

  I have no problem with CreateStrainGageChannel, I put 8 channels and other settings.

  Regarding the ConfigureSampleClock, I have some doubts. I want a continuous acquisition, then I put the internal rate, signal source 1000, continuous sample mode, I set the size buffer using the parameter "sampled by channel.

  What I wonder is:

  (1) can I put any kind of buffer size? That the limited hardware of the module (9235) or DAQ (9188)?

  (2) can I read the buffer, let's say, once per second and read all samples stored in it?

  (3) do I have to implement my own buffer for playback of data acquisition, or it is not necessary?

  (4) because I don't want to lose packets: y at - it a timestamp index or a package, I can use to check for this?

  Thank you very much for the help

  Hi Roberto-

  I will address each of your questions:

  (1) can I put any kind of buffer size? That the limited hardware of the module (9235) or DAQ (9188)?

  The samplesPerChannel parameter has different features according to the synchronization mode, you choose.  If you choose finished samples the parameter samplesPerChannel determines how many sample clocks to generate and also determines the exact size to use.  But if you use streaming samples, the samplesPerChannel and speed settings are used together to determine the size of the buffer, according to this excerpt from the reference help C DAQmx:

  

  Note that this buffer is a buffer software host-side.  There can be no impact on the material available on the cDAQ-9188 or NI 9235 buffers.  These devices each have relatively small equipment pads and their firmware and the Driver NOR-DAQmx driver software transfer data device to automatically host and the most effective way possible.  The buffer on the host side then holds the data until you call DAQmx Read or otherwise the input stream of service.

  (2) can I read the buffer, let's say, once per second and read all samples stored in it?

  Yes.  You would achieve this by choosing a DAQmx Read size equal to the inverse of the sampling frequency (during 1 second data) or a multiple of that of the other playback times.

  (3) do I have to implement my own buffer for playback of data acquisition, or it is not necessary?

  No, you should not need to implement your own stamp.  The DAQmx buffer on the host side will contain the data until you call the DAQmx Read function.  If you want to read from this buffer less frequently you should consider increasing its size to avoid the overflow of this buffer.  Which brings me to your next question...

  (4) because I don't want to lose packets: y at - it a timestamp index or a package, I can use to check for this?

  DAQmx will meet you if all packets are lost.  The default behavior is to stop the flow of data and present an error if the buffer of the side host DAQmx overflows (if, for example, your application does not pick up samples of this buffer at a rate equal or faster than they are acquired, on average).

  If, for any reason, you want to let DAQmx to ignore the conditions of saturation (perhaps, for example, if you want to sample continuously at a high rate but want only interested in retrieving the most recent subset of samples), you can use the DAQmxSetReadOverWrite property and set it to DAQmx_Val_OverwriteUnreadSamps.

  I hope this helps.

• I do not use sync and am not connected? Why my favorites are synchronization?

  My desktop computer has a series of bookmarks that I use at work. My home PC has another, different set of bookmarks that I use at home. I do not use sync and am not connected to sync on each PC. Why my favorites are the synchronization between two PCs? For example, I noticed several bookmarks near the top of my bookmark menu over a line of separation that I do not have to work. I deleted them. I come home and find those missing same bookmarks from my PC at home. I do not want to synchronize anything between the two computers, why what is happening?

  Maybe an add-on is the sync these for you.

  Refresh (called "Reset" in older versions of Firefox) can solve a lot of problems in restaurant Firefox as his default factory while saving your bookmarks, history, passwords, cookies, and other essential information.

  Note: When you use this feature, you will lose all the extensions, toolbar customizations, and certain preferences. See article Firefox Refresh - reset modules and parameters for more information.

  Refresh for Firefox:

  1. Open the troubleshooting information page using one of the following methods:
     • Click the menu button

       

       click Help

       

       and select troubleshooting information. Should open a new tab containing your troubleshooting information.

     • If you are unable to access the Help menu, type Subject: support in your address bar to bring up the troubleshooting information page.
  2. At the top right of the page, you should see a button that says 'Refresh Firefox' ('reset Firefox' in older versions of Firefox). Click on it.
  3. Firefox closes. Once the update process is complete, Firefox will display a window with the imported information.
  4. Click Finish and reopen Firefox.

  This corrects the problem? Please report to us!

• I need to sync bookmarks between Firefox Sync and Seamonkey. Is this possible and if so how?

  I use Firefox and Seamonkey, as well on the same computer and also on other computers. I would like to use Firefox Sync to synchronize bookmarks between Firefox and Seamonkey on all my computers, but I do not understand how to do this, because the browsers seem to use their own separate servers.

  Is this possible and if so can you tell me how to put in place.

  Thank you.

  I understand the confusion!

  I'm not a Mozilla support person, but according to my experience, synchronization must be called Sync in Mozilla, Firefox or Seamonkey Sync...

  If you create an account in Firefox, this account is accessible to Seamonkey.

  According to the instructions of Mozilla in Firefox, you open 'Options, sync, add a device' and in Seamonkey "sync Setup, I already have an account. The text here is a little confusing because you have to read 'I already have a Mozilla sync account', otherwise, you tend to think that it involves a Seamonkey sync account...

  Then click 'connect' and Seamonkey then provides three fields of characters that you enter in the appropriate fields in the dialog 'Add a device' Firefox.

  I think it's confusing that in Firefox, the server is called 'Server of Firefox Sync' and same Seamonkey offers a "Seamonkey Sync Server', which suggests that they are two completely separate entities, not connected.

  I hope this helps!

• Update of iTunes. IPod sync and lost everything but 10 audio books, passed to Touch, four selected works, only on the Touch and not the selected one. Afraid to synchronize other devices that I'll lose everything. ITUNES update BUG

  I updated iTunes 10 Windows a few days ago. I sat to continue listening to an audiobook on my iPod. 110 audio books in sync with the iPod, there are now 10 and not that I want to listen to. I opted for a touch and tried to load the book on that. There are four books selected for the touch. The book I want to not sync and there is only one book on the Touch.  This book is not all the book selected for synchronization.  I am afraid now to sync one of my other devices to iTunes because I'm afraid I might lose even more data.

  Of course, there is a bug in the new update iTunes 12.3.3.17.  Help, please.

  Are audio books in your library? If it is not in your library can see you in your media folder? Your library authorized the Apple ID is used to buy the books? The upgrade of Windows can break the record of the permission on the computer.

• Satellite A300-1MX - sound & video are not in sync and video lag

  Hey everybody,

  I bought a new Toshiba Satellite A300-1MX two days ago and had installed XP on it with Service Pack 3. I only noticed now that I tried to play a video that I took with my camera it was very laggy, the audio and video are out of sync and the video is laggy. It can t be my camera because this has happened also with the built-in webcam, and my office is my cameras back common videos.

  Does anyone have a solution?

  Thank you

• Audio Out of Sync and Insert Clip out of a framework

  I record my audio and video separately. I use the merge Clips feature to merge together, now made dozens of times, never a problem. He did it with this new project, everything looks and sounds very good.

  But when you change the pieces of an element in a sequence, each inserted bit is the "audio is out of sych" red text. It is out-of - 0:72 to a clip or - 0:87 for another.

  However, it is not enough for me to see when I play it back, so I did fi from it as I change. Sometimes I slip in sync to remove the red text, I can't make a difference.

  But also sometimes when I insert an element in the current sequence, the marker/cursor script (don't know what it's called, the line blue large marking this place in the sequence where everything I insert will be inserted) is disabled by a frame. Sometimes it's off in one direction, which means that I get random empty images in playback, or it is off in the other direction and I am slowly accumulated unique axe off executives.

  Someone has an idea of what's going on? How the audio is out of sync in the first place? Why the function Insert Clip move the cursor in a strange place?

  Nevermind, I figured it. I chose the wrong preset when I made a new sequence. 60 frames per second instead of 59.whatever. >.

• When I test the scene/video, its out of sync and zoomed in?

  When I test the stage or film, audio and mouth out of sync and his also expanded a bit, Eg, only its head is visible above the bottom of the screen, instead of what should be his head and his chest. No idea how to solve this problem?

  for her, if it is attached to a timeline, click the keyframe where the sound is instantiated, and in the Panel properties, change the mode of synchronization of flow.

  for video editing, attach a screenshot showing your scene with the head (including the zoom factor of scene) and a screenshot of the head in the test environment.

• Audio out of sync and missing

  I have several clips of my Panasonic LX-5 (720 p). I created a new project (CS 5.5) and import the clips. When I play the file directly from Windows Explorer, all right. However, in the timeline, the audio is ahead of the video, then partially through an element, the audio disappears altogether. In addition, the line in the upper part of the sequence is yellow (above the transitions, it is green). I thought that perhaps the final exported file would be nice, but he had the audio out of sync and missing in the same places, too.

  Any ideas what's happening here?

  Thank you

  Jay

  Thanks for the offer, Jim. It turns out that, delete the files from the cache of forced media audio again in line (as when a fall new video clips in the bin in a project). That fixed it.

• LabVIEW 2010 with CDAQ-9188 and NI9205

  Hello

  I use the NI CDAQ 9188 with the Analog Input Module NI 9205. The specification of the NI 9205 module shows that there

  16 channel differential channel, or simple 32 took end. I use the 'DAQ Assistance' in Labview to configure the

  Module OR 9205. But it only allows me to select 8 differential channels. After I put the 8 channel, then the

  Terminal configuration allows no differential inputs. It allows only to CSR or NRSE entered.

  I'm doing something wrong? I just bought the camera to use for 16-channel differential reading.

• Module AO trigger using PFI on the cDAQ-9188

  I use a cDAQ-9188 chassis with an AO (NOR-9264) module.  Is it possible to configure a PFI (channel on the frame) as an input signal to synchronize an AO channel with the trigger?  Here's what I'm trying to do.  I need a channel on the AO module to switch voltages in sync with the trigger when the user "push a button".  So once the button is pressed, the channel of the AO will not change until the next trigger pulse.

  Thanks for your help

  Ben

  Hello Ben

  I hope you are well.  The consensus is that it is possible.  Have you tried this yet?  If so, can you tell me what you have tried and how you made a lot of progress?  I recommend the following VI example: Cont Gen tension Wfm - Ext Clk.vi.  Are you able to get all the functionality you are looking for this VI.  It was recommended that I'm showing you this.  We find this VI under help--> find examples and then material input output &--> DAQmx-->--> voltage analog generation.

  Please let me know how you are progressing and if you have need of all aspects of this example explained.  Thanks for choosing National instruments!

  Sincerely,

• How many quadrature encoders may be read together with the cDAQ-9188 chassis?

  We will record position periodically 8 engines (at the same time as we are to the corresponding samples entered analog).  It seems that the 4 built-in counters limited chassis to 4 encoders.  Is this correct?  I am familiar with modules of counter PLC which manage high-speed counting, and then the CPU posts periodically to update the total values.  This is how the NI 9401 card would work?

  Hi jtrout,

  You are right the 4 built-in counters than the cDAQ-9188 chassis 4 encoders.  The following article deals with the use of the NI 9401 card for encoder measures: http://www.ni.com/tutorial/7109/en/.
