• NEITHER 9234 with quasi static analog voltage

  Hello

  I have a NI 9234 (4 channels + / IEPE 24-bit 5V) attached to a chassis cRIO module. This module is ideal for accelerometers and microphones where the tension is in constant evolution (ie; measures of variation rates).

  I also have a module OR 9237 (4 channels 24-bit full-bridge module analog input) attached to the same cRIO. This module is ideal for measure variable voltages of strain gauges (quasi static and dynamic loads).

  The attached graph shows the two channels, collected synchronously, but as you can see the (red trace) cell breaks down (as it should), but then drifts back to zero on its own, when in fact it should remain low just like the extensometer is beam. After all, the two sensors are physically secured.

  Q1: Would that have something to do with AC/DC module 9234 internal coupling?

  Q2: Is it really possible to collect "quasi static" ongoing tensions by using a NI 9234 module?

  No explanation as to why this occurs, or if there is a way to remedy this would be appreciated.

  Kind regards

  Andreas

  Coupling AC/DC must do a lot with your question. In mode AC voltages static will be fitered outside and the 9234 measure indeed only change voltages. In DC mode, the voltage goes directly to the AD converter and you can also detect static tensions.

  A minute of Googling gave me the answer, this load cell electric piezo can measure dynamic changes, as any charge will escape the path the lowest resistance and the signal will go to zero after a certain time. I guess the other device you were using higher internal resistance (which is relatively low on the 9234), so it takes more time to what he flees, but he also took on the picture you attached your second try.

• NEITHER 9234 Channel Config

  I have a NI 9234 inside a cDAQ, and I was wondering:

  Can I configure each channel individually, while measuring the two at the same time?

  I want to have the excitement of 2mA enabled on a channel, but not the other I read / compares the two signals simultaneously.

  So far, I have to choose Toggle both on a property node, and not what I need.

  Thank you

  William,

  You can of course! Please take a look at this article:

  http://digital.NI.com/public.nsf/allkb/3AD6CCE935192B4086256F6B0079CB1F?OpenDocument

  The last paragraph is the most relevant: If you want to have different settings on each channel used, the best thing to do is to create a channel DAQmx of different types of measurement for each of your different settings. These different channels DAQmx can always be used within a single task DAQmx. For example, if you have three starters of micro and single voltage, you can create a type of measurement microphone and a type of tension using the DAQmx create channel VI. The channel will be associated with three physical channels while channel voltage will be associated with one. Voltage channel can have different settings, factors, coupling, the fat and IEPE properties compared to the microphone channel.

• NEITHER 9234: sampling rate: cRIO, FPGA

  For the NI 9234 module, before Panel block diagram of my my cRIO FPGA code is as below.

  The sampling rate (speed) is selectable between certain values as shown below.

  You have an idea how I can do the sample with a lower rate that is smaller than the option of character (1.652 ksps / s)?

  

  

  

  Hi Cashany,

  Take a look at this link. Page 16 describes the limitation that you run in. The main time base are divided essentially only toward down to some data because of the way the camera rates physically handles analog and digital filitering. So it's not really a way to divide the beyond that point.

• My Favorites are gone and I can't make new bookmarks. I tried to restore their by clicking on the backups and downloading Backup and neither will not work.

  This is as far as I know. I followed the instructions to restore and nothing works.

• TAB GROUPS die after closing the window, restoration of session does not apply and neither is history! I do not think that I have been warned!

  On leaving firefox, update, then restart, I lost the ability to restore sessions. I restored the Group of tabs in the past; It's different. My tab groups are lost forever and I don't remember even be warned about losing when the window is closed (as often happens and then I avoid close it.)

  I sync my tab groups, but she must have sync'd their disappearance because I lost. Tab groups really should have always been separate from the window (as a form of records) - I don't know why I found myself never adopt this powerful feature knowing how bad it has been supported. I had actually named groupings with 2dont reading lists etc... the year value of groups... and I shared it between devices...

  In fact, I watched the sessionstore.js file, it seemed ok - I do javascript professionally. I think I can close this because there seems to be a lack of functionality/design of browser that we can solve a problem. my other computer did the same thing with clamping my tab groups and the closure of the window... it's a "feature" not a bug. I thought that maybe someone knew something that I do not have as to why this is so wrong.

  I'll just have to live with attention restore or restore backups the sessionstore.js if for some reason, he gets lost. Including me accidentally close the window and press on enter without thinking (Yes, I get that I can restore; but the problem is that I wouldn't restore groups of tabs because they are so easily killed in multiple ways.)

• My 8 Firefox Menu button does not work and neither does the right click in the window of firefox

  It seems that all drop-down buttons in the browser, including the bookmarks dropdown in the toolbar and the main menu button (firefox), no longer work. This happened after that I upgraded to firefox 8. I tried uninstalling and reinstalling several times all also the removal of the preferences user and all that but that does not work. But everything seems to work properly in safe mode. So I disabled all my addons in the normal mode, but cela still does not resolve the problem. My right click does not anywhere in the browser window either. And also, although the menus are not displayed, it seems that they are still there because if I click in the area that a the function button active, that's how I was able to disable addons.

  Safe mode disables extensions in Firefox 4 and later versions, and disables hardware acceleration.

  • Tools > Options > advanced > General > Browsing: "use hardware acceleration when available.

  If disable hardware acceleration works then check if there is an update available for your graphics display driver.

• Firefox opens, and neither does Profile Manager

  So yesterday some site to search Google (Kilauea photos search string) done something wacky, and now Firefox 4.0.1 will not start. Safe mode does not start. Profile Manager does not either. Uninstalling Firefox, by removing the Firefox of Program files, running a registry cleaner to clean the remnants of Firefox, running a full MS Security Essentials scan who find Trojans villain, and then reinstalling Firefox works only for the initial session. A replay of Security Essentials and a race with IObit Malware Fighter is nothing. Once I got close and restart, same as at the beginning. Internet Explorer 8 and Firefox 3.7a5pre minefield version seem to work normally, other mines fails to remember the passwords even if it is checked. Any ideas on what to try?

  Beta version 5.0 is not really get updates of security by saying as with point versions minor for 3.6. * for example. The 5.0 Beta recent 5 (which will be soon in Beta 6, may even be a b7) could be even more up-to-date then 3.6.17 and 4.0.1 even in a sense. Unlike with the latest versions with release candidate RC for the exit, the last last beta deemed good will become final.

• The output on my Macbook Pro is not giving me the drop-down list, & happens either in the port of the helmet or digital port and neither one is what I need. I tried turning off the computer and hold "Shift"' Control', 'Option' with the power-o ".

  The output on the sound output box has no drop downs. The audio output suddenly disappeared and when I went to the 'exit' sound in 'sound preferences' the only thing that would show was the headphones.  After that I tried a couple of things suggest that 'Helping Apple', sometimes in digital form & everything that happens you can't change for something else.  Things I've tried suggested by Apple press help were the "Shift control option buttons & button / stop at the same time."  or press the Option, the command, the P & R key as soon as possible after you have pressed the button On.  Hold down until after the second gong during a manoeuvre.   This did cause the digital option, but none of these 2 is the one I need.  Help

  Perhaps, it would be useful to know what that is exactly the one you need. Are get you an external speaker output or anything like that. Also, it would be useful to know the operating system you are using.

• NEITHER 9234

  Maximum sampling frequency for the NI 9234 is given as 51.2 kech. / s in documentation NOR. This means that for a House to measure collection measures of 3 different instruments rate is 51.2 kiloSample/second/3 = 17 kiloSample/second. It's 17 000 samples/second. The number seems very high. Could someone please confirm if this is correct?

  As noted by Jeff, a 9234, one ADC per channel.  So if you're sampling 3 channel 51.2 kech. / s, then you get 153,6 kech. / s.  To 3 bytes per sample, this means you broadcast 460.8 Kbps.  It is well within the ethernet or USB, specification according to the frame that you use.  I hope this helps.

  Thank you

• Share data between a PC host and NEITHER sbRIO-9626 connected by Ethernet

  
  

  Hi Sophiec,

  In fact, shared Variables are a good way to share data between a host and a target. However, this is not the only way for data sharing.

  On the follow-up document, you will find different ways to do it: http://digital.ni.com/public.nsf/allkb/48D244EC86971D3986256BD4005CCC28 as:

• cDAQ 9191 and neither 9215

  CDAQ 9191 or NI 9215 there a fpga module that we can program?

  Is it possible to perform mathematical operations with the signals that we gain by using cdaq 9191 and NI 9215?

  Once the 9191 is set up in MAX, you can read the channels on the 9215 and do what you want with the data.  The 9191 is used only to transmit data from the 9215 on a computer that is running LabVIEW, where you can perform mathematical operations.

  If you want or need FPGA, you get a compact chassis of RIO, not a compactDAQ chassis.

• Display and NEITHER 3100RT

  Hello

  I need to develop a real-time application, but display a façade on a 40 inch screen. User interaction would be a mouse.

  Initially, I would think to use a RT controller and a PC for the front panel... maybe even the 3100 with hypervisor, but is in any case use just the NOR 3100RT without having to connect to windows?

  Is there a USB media on the RT controller? If I could get entry USB mouse.

  And are there limits to this controller display when you use just the version RT?

  Thank you

  Jevon

  Hey, Jevon,.

  When it comes to USB ports on the NOR 3100RT, they take over a keyboard and a mouse. However, these only really serve to set the BIOS and do nothing during the execution of an Application of the RT as user interfaces are not deterministic. LabVIEW RT supports USB storage for data recording devices and will appear as another drive on the controller of RT. Some info on the caveats of via a USB port on a great goal of RT can be found on this Knowledge Base. Flash drives talk where USB ends for RT OS support so plug in a USB printer, wifi card, blinder (maybe?), it probably won't work.

  On the screen. Outputs VGA and DVI on the controller are usually just used to display the Terminal or the BIOS of the controller, but can also be used to display pictures using the drivers IMAQ. Probably the most common use would use the monitor to view the video from a camera in real time.

  It's a piece of code using the RT IMAQ video Out.vi to create a screensaver RT attached!
