  There is a version of 'Raw' DAQmx Read (see image).  This is probably what you are looking for.

• How can I pause and resume the analog output using DAQmx?

  I use a DAQ hardware to produce an analog waveform.  I would like simply to break the output of the wave and then resume where it left off.  I use DAQmx and LabVIEW 2011.

  I've seen examples that use a digital or analog break trigger, but I would take a break in the software only.  How can I do this?

  Hi Joe!

  I spent some time thinking about it and I realized that you can technically use a fundamental mission of the analog output, as you previously wrote that runs continuously. However, the generated output samples are controlled by the sample clock pulses, and can be manipulated to fit our needs "suspension."

  To do this, we will need another counter task that generates a pulse train (see our examples of shipping under material input and output > DAQmx > generating digital pulses > generate dig Pulse Train - Continuous.vi) that stops and starts the user to choose. This can be in another quite VI or controlled by software. We will use this as the task of our output sample clock.

  Then, the task of the AO, wire a constant to the sample clock source and select ' DevX/CtrXInternalOutput"based on the counter that you specified in the task of counter. You will need to choose "I/o name of filtration" and check the box that says "include advanced terminals' and right-click of the constant. See picture attached as a reference. In this way, the task of the AO is constantly running, but it generates only actually all data when the meter running task.

  

  Let me know if you have any questions!

  Have a great day!

• How self test 6713 using DAQmx programmatically?

  I use DAQmx and I need to be able to perform a self-test on a map of NI 6713 analog output without using MAX. Any suggestions?

  DevtPro,

  As you can see in this document , the recommendation was to use Reset running as self-test in addition to other things.  Currently in DAQmx 8.9 and later there is a Self - Test.vi DAQmx that allows to run just a self-test.  I already submitted a change to this document and it should be reproduced soon.

  I think you could use DW, but it would be browser based and you need to understand a lot about html, css and javascript to do. Adobe Captivate seems closer to what you want: http://www.adobe.com/cfusion/search/index.cfm?term=buy+captivate&loc=en_us

• Use DAQmx counter or relaxation?

  Hello

  I am beginner with products OR and I'm triyng to get a result with an acquisition of data USB-6008 and ANSI C API

  My goal is to detect the pulse (approximately 1.4V for about 10 ms) and calculate the time between the rising edges (should be between 0.5 and 2 seconds).

  As the square pulse, I connected the cables to the digital lines GND and PFI0.

  First I tried to use the functions of triggered, but I failed.

  So, I am now using the meter functions, but I always got an error and I don't know how to fix it.

  Here is the code:

  Int32 error = 0;

  TaskHandle taskHandle = 0;

  char errBuff [2048] = {'\0'};
  printf ("=> DAQmxCreateTask... ");

  DAQmxErrChk (DAQmxCreateTask("",&taskHandle));

  printf ("OK\n");
  printf ("=> DAQmxCreateCICountEdgesChan... ");

  DAQmxErrChk (DAQmxCreateCICountEdgesChan (taskHandle, "Dev1/ctr0", "", DAQmx_Val_Falling, 0, DAQmx_Val_CountUp));

  printf ("OK\n");
  printf ("=> DAQmxCfgSampClkTiming... ");

  DAQmxErrChk (DAQmxCfgSampClkTiming (taskHandle, "" / Dev1/PFIO ", DAQmx_Val_Falling, DAQmx_Val_ContSamps, 1000 1000 '));

  printf ("OK\n");
  printf ("=> DAQmxStartTask... ");

  DAQmxErrChk (DAQmxStartTask (taskHandle));

  printf ("OK\n");

  I got the following result:

  => DAQmxCreateTask... Ok
  => DAQmxCreateCICountEdgesChan... Ok
  => DAQmxCfgSampClkTiming...
  DAQmx error: measurements: request the value is not supported for this property value.
  Property: DAQmx_SampTimingType
  You asked: DAQmx_Val_SampClk
  You can select: DAQmx_Val_OnDemand

  Task name: _unnamedTask<0>

  State code:-200077

  Can someone tell me how to fix it?

  In addition, if you think that there is a better way to implement my requirement, feel free to tell me.

  Thanks in advance

  Mobill

  Hello

  Finally, I managed to get the pulse with the following commands:

  DAQmxErrChk (DAQmxCreateTask("",&taskHandle));

  DAQmxErrChk (DAQmxCreateCICountEdgesChan (taskHandle, "Dev1/ctr0", "", DAQmx_Val_Falling, 0, DAQmx_Val_CountUp));

  DAQmxErrChk (DAQmxStartTask (taskHandle));

  while (cVal == 0) {

  DAQmxErrChk (DAQmxReadCounterScalarU32 (taskHandle, 10, & cVal, 0));

  }

  Thank you Thomas for your help.

  Best regards

• Should I buy a Base Station for my Apple products to use Time Machine?

  Should I buy a Base Station for my Apple products? I have a Netgear CG3000D-RG gateway and also use Windows with this modem/router. I'm not able to backup using time machine and bought an external hard drive PassPort but I find it pretty annoying having to plug it in to my MBP whenever I want to do a backup. I would like to use the most convenient airport on my MBP feature, however, it seems pointless unless I have connected to my Netgear router/Modem base station. If I have to buy a base station to make the backup of my MBP easier? I also use 6s and iPad Air iPhone. I would be able to save these features too? Thank you!

  1. you must either have a Time Capsule or connect the drive to your computer when you perform a backup.

  2. Time Machine isn't back from iOS devices directly; they should be stored on a computer and the computer saved Time machine.

• Satellite A500 Toshiba product recovery using error

  I recently ordered a Toshiba product recovery for my Toshiba Satellite A500, which runs on windows 7. When you use the product recovery DVDs fine, but towards the end I get an error message. And now I can not even boot my pc, he repeats to me "BOOT MGR IS MISSING".

  Thank you

  Which is really strange. And the same thing happen when you use the recovery DVDs over and over again?
  Always the same problem?

  I looked at the help and it says select (using shiiping examplecontrol witch individual relay) BROWSE from the dropdown under the relay.

  Then that's it!  I tried 'CTRL' then the channels I wanted... nothing...  I tried 'SHIFT', then the channels I wanted... still nothing.

• PSC-2 2220 connected to the same Bus RS232, using turns

  I want to do using two PSC-2220 experience which, in turn, use the same RS232 cable (I intend to fill the cable). I manage the turns with shared variables. Is this possible? I mean, is that of the interface RS232 can be shared if a CFP2220 does not use it?

  Hi ggarza.  RS - 232 is not designed for more than two devices to communicate.  It might be possible with enough

  diodes and prudent to programming, but I expect it would be a challenge.

  A better approach would be to use RS - 485, which is designed to support more than two devices.

  Information of RS - 485.

  Ago RS485 to RS232 converters available which will allow you to connect your device; controllers of-2220

  already have a RS-485 port.
