• Speakers and digital output device problem

  So yesterday, I installed a new video card. A Nvidia Geforce GT220. After installing it I noticed that my speakers were not working. The default program I used was Realtek High Definition Audio. I checked in Device Manager and noticed that the Realtek HD Audio Driver/program had a small yellow triangle with an exclamation point and that there are 4 new options named Nvidia High Definition Audio. Whenever I tried to run Realtek it says that the program has been installed, but may not be installed correctly. He said it was a Code 10. So finally, I deleted Realtek but the Nvidia High Definition audio drivers did not work. So, I deleted the drivers from Nvidia High Definition audio and tried to reinstall Realtek. My computer says that I installed it but there is no program to access my different options.

  Now when I check the sound folder, during playback it says peripheral digital output (HDMI) 4 times.
  Although the sound does not work.
  Im just trying to run her on my Logitech X 540 speakers. When I plug the speakers that they appear not yet as an option in the sound folder.

  I don't really know what I can do to make it work.

  I have a HP with Windows Vista 32 bit a1730n.

• 6534 PCI for digital output finished generates a continuous output

  Hello

  I use 6534 PCI for my application, where I generate a digital output, a model finished variable length in a continuous loop.  the code runs without error, but I'm not able to justify the behavior of the map. I intend to use the code inside the while loop as a Subvi and if I change the 'command' at the entrance table during each call to the Subvi, the output should vary according to the directives of the entry of the 1 d array.

  But this is not the case, the loop displays the previous value that has been given to Scripture DAQmx. If the control panel is changed the output instantly does not change. It takes a while before the actual output changes. The length of the array command I give is also 88 & 133. When I realize that the output is wrong, I disable the DAQmx write vi by a structure of the case, I would expect an error that the output buffer is empty, but rather the old value is generated whenever the start Daqmx vi task is exectuted without.

  My tax any problem is that the output buffer is not get replaced with the new value, but I'm specifyng the size of buffer, performing a registration every time and start the task, waiting until the task is done and the task stop. Each stop & writing should delete and empty the buffer, but I did not understad what goes wrong.

  Also, I thought that maybe that orders are put in queue up in the output buffer, acual generation is not as fast as the call of the DAQmx write & start, but if that's the case then even if I stop the vi the generation should be until the buffer is empty, but that doent happen VI, break breaks of generation. the number of iterations is equal to the generated models. If anyone can help as to what could be the problem?  find code attached below.

  Hello

  If I understand the problem you are experiencing, then the reason for the typical behavior when you run the VI, it is that you are not clearing the DAQmx task whenever you intend to go for a fresh DIO write. You stop just the DAQmx task that seems however to clear the buffer on board space.

  With this post, I am enclosing a VI of the sample that should work according to your expected behavior. You can even call this VI as a Subvi and can use it to update the DIO port with a digital model of variable length fees. Another fact that I would like to point out, is that, once you have initalised one table, it is not possible to reduce the length of the array. You can only increase by adding new elements. According to your needs given that the digital model that needs to be updated will be of variable length, each time you cll the Subvi, you must create a freash of appropriate length and feed it as input to the Sub - VI. Inside the Subvi, according to the length of this array of entry appropriate buffer space is allocated.

  Do trust this solution help solve you the problem, otherwise do not hesitate to go back.

• synchronize NI 9514 with NI 9401 for digital output

  Hello

  I need to write code to trigger a laser for a PIV system. I use the NI 9514 with training AKD to order a servo. I need to send a + 5V signal to trigger the laser at an angle of rotation of the motor (this is repeated for each turn of the rotor) specific. I also have the NI 9401 DIO. Any idea/example of how to proceed will be much appreciate. I use the scan to the NI 9514 mode, my system is a CRio-9022 with 9114 chassis.

  Thank you very much!

  According to me, that the example to compare periodic Position is what you are looking for. The description States "shows how to use the output of compare position to generate an output signal to a regular period.

• No sound from the computer with connected generic speakers VISTA SP2. Symbol pregnant shows active with the Digital Audio device.

  I have vista SP2, I connected to generic stereo speakers using the green light at the back of the computer. Vista does not recognize the speakers. The speaker symbol at the bottom right shows "digital (HDMI) 2 high definition output audio device." It shows active. I had this problem before, and VISTA should pick up 'speakers' something to that effect. I have no sound until it captures "speakers". I can't get VISTA to recognize this. It keeps starting with the digital audio device. Don't know what to do, checked all the forums. It should just pick up these simple generic markets good speakers. Before SP2, I lose sound when VISTA is in standby mode. He would then turn off the stereo speaker and replace the digital output device driver... However since SP2 I can't get VISTA to recognize that I have just connected speakers and not a digital output device.

  Yes, when I uninstalled the driver, THEN shut down the computer and then restarted, he picked up the device high definition audio "speakers" good pilot is NOT the

  "digital (HDMI) 2 high definition audio output device that he used to pick up."

  I now have sound!

  I hope that it stores the right driver now as in the past, when VISTA went into sleep mode, it will disable the speakers, and you have to restart every time.

  Thanks for your help.

  You can add instructions to boumediene, the fact that you must RESTART your computer to search for new drivers, once you uninstall.

• Problem with a digital output in the information of an analog input

  Hello

  I use a SCXI-1000DC module with a module of the SCXI-1600, SCXI-1531 module and SCXI-1163 module to receive an analog of an accelerometer signal and a digital signal.
  I claim that the accelerometer is constantly monitored, and the output is on when I want to, by an impulse that I comand in labview.
  I use a rate 25 k and a 12, 5K samples per channel on DAQmx Timing.

  I notice in DAQmx read, if I put a sample of hight by channel, the output is not there when I want to, and if I put a few samples per channel, I exit when I want to, but the program seems to be slow with the passage of time. I don't know how I can solve this problem!

  I'm sorry for my English, and I hope you can help me.

  Thank you

  Silvia

  Hello Silvia,.

  If you ask a larger number of samples, the labview diagram will stay longer in the DAQmx Read function, so the while loop runs slowly, and the digital output is updated less often.

  I suggest that you use 2 separate while loops: one for the analog input and the other for digital output, so that each loop might run at a different speed.

  Best regards

• Is it save to use the digital output as a digital input for another channel signal

  Hi all

  I know it's a stupid question, but I don't have another generator of signals by hand. What I want to know is, can I use the signal digital output of my USB-6001 as an input for the same signal device, but on other digital port? I wasn't directly because I don't want to burn the device...

  Thank you

  Done all the time. No problems.

• What is a digital output (DO) good for?

  Actually, I wanted to use the outputs digital to move from a 24 VDC circuit (to turn on/off other devices etc.).

  But the current output outputs digital is so low that I have even impossible to pass an opto-coupler (opto isolator).

  That's why I wonder you use outputs digital for if you cannot use them to change anything?

  Of course, I can create a circuit MOSFETS or transistors to switch 24VDC power with the TTL 5V digital output signal. But I guess that most of you do not :-)

  And of course, I know that I can buy OR relay modules/cards. In fact, I have many digital outputs available and do not want to buy new modules/cards.

  Now, I can test and actually I get 10mA @ 5V on a digital output of NI 9401 (DIO), using the digital output to pass an opto-Coupler.

  It seems that the information contained in the data sheet are supposed to mean something else...

• Digital I/o, the use of P0.0 for 5V output

  On my data acquisition device (USB-6009), I already use the pinout + 5V and ground to control a sensor. I need to put another of the same sensor in my test set-up. Can I use the P0.0 as one + 5V out? and just ground the same pinout (32) of the load?

  

  

  Why? You can wire the + 5 at several locations. If the detectors must be much more current, probably digital output will not source enough.

• I am trying to use the speakers on my midi keyboard as the default output for Windows 7 device

  I am trying to use the speakers on my midi keyboard as the default output for Windows 7 device. I have a midi keyboard Casio CTK-3000 and you want everything to sound out the two speakers on the keyboard.

  You can not.

  You can exchange midi data between the keyboard and a PC via the USB port. But not strong like the keyboard is not an audio device and therefore doesn't have the proper drivers.

  MIDI is not good in itself, it's just that a series of statements sent to a electonic module that transforms these 0 and 1 for sound samples. This isn't the same principle as an audio card/device.

  See you soon,.

• How to select the output device HDMI as audio playback for Windows Media Center device

  Output audio media center units

  Hello

  I'm trying to set up my media center from windows to windows media center of output through a separate audio device audio device by default.

  In this case, I have hdmi output that I want to be the output for windows media center and my realtek analog to be the default for all the rest.

  So my overall question is how I make windows media center requires is not the default audio device.

  Thank you

  Andrew

  Method 1 is useless. Does that change the audio device by default in the system, what the user seeks specifically not to do.

  Method 2 has no effect at all on Media Center.
  The answer seems to be no, Media Center only works with the audio output device by default.
