• Population of list for the NI USB-6008 channel

  Hello

  I use labview version 2011. I have worked with USB 6008 for two months, but I encountered an error constantly even if I restart or shutdown of the PC for a while. I connected to my channel 6008 AI0 asensor and DAQ Assistant is not populating the available analog channels. Please someone help. Since it worked fine for a month, but not today.

  History was end I solved my problem after seeing the "Error in the knowledge base" pecautions on the site of NOR. Now the help data acquisition work.

  But I wonder how MAX data are linked with these DAQ contest. Some can clear me how MAX is related with all these functions of time real Labview.

  By the way, I'm using labview for two months.

  Thank you very much.

• Pulse counting with USB 6008

  Hello world!

  I have a project with USB 6008. I want to count impulses (for special features: count the pulses of the encoder) use USB 6008. I wirite with DAQmx to test a simple. But it do ' t run. Please see and help me to do this exercise. I just borrowed 6008 USB so I don't have any experience with USB 6008. Thank you! It's funny.

  Looking at the PFI0 manual (pin 29) is correct and I don't see anything wrong with the code and example should work. I have a M-series card, not a 6008 and it works for me. This error code is meaningless if. Are you sure it's the number?

• Get incremental counter/sound to work along side with action with usb-6008 with labview tia sal22

  Get incremental counter/sound to work along the coast with usb-6008 with labview tia sal22

  Hi all

  I can get this vi to work if they are distinct from the vi but I can't join them together

  Example of my error:

  If buffers are set to 0 the freq counter increment works, but no sound
  If the buffers are set to 1 the audio works fine but is not increment the Freq counter
  If the buffers are attached to more 1 clicks and pops are coming

  That's what I'm doing:
  (1) have the frequency of increment of my internal sound card to a certain level as .01hz a second until he gets to 20 000 hz

  (2) use my device usb-6008 daq, which is connected to the same machine to measure the voltage at the same time. (I am in a position very low voltages between 1-5volts)

  (3) output to a worksheet text file which will show you:

  time in seconds, frequency, voltage
  0,400.01,2

  1,400.02,2.5

  2,400.03,1

  I'm a bit confused about how connect the increment and the audio during the measurements with the usb-6008 housing on the same machine
  at the same time and in the same VI.

  Anyone have any ideas?  I'm using labview 8.5
  TIA sal22

  Ha ha you have been deceived by a dynamic thread. Insert a convert from Dynamic Data Express VI (Palette to own: Signal handling screw Express) between the daq read and build the array function. Then it won't work. Now the value in the dynamic data is only converted to a numeric value

• Loss of communications with USB-6008

  I have a USB-6008 be used to control a couple of valves with its digital output channels. The digital output channels are a relay that energizes the solenoid valves (valves are 115VAC) switching. The USB device is connected to a USB port on laptop.

  The software/hardware was working fine, then some time while it was connected there was a power surge. There was a 2 a fuse on the 115 VAC line that blew.

  After this communication surge was no longer able to be implemented with the box USB-6008. Is it possible for a power surge affecting the USB device, even if his power comes from the power supply of 5V USB?

  Things I checked so far.

  Restart the computer with the USB unplugged and start back up - no connection

  Check the Device Manager for the USB device to be present - not visible in the Device Manager

  Check MAX for device - does not present as gift

  Check the wiring to the son of course drop - no defeated cables

  try on different laptops - connection

  Connect other USB devices to the laptop USB - another fine feature of devices USB slot

  Check the + 5V channel on the USB device and do not read a voltage

  Any indication seems to be that, somehow, the USB device has been damaged during this surge? Is there some kind of diagnosis offline, I do without seeing the unit online?

  Hello the plough,

  It looks like the surge caused a sort of feedback of the valve of your USB device. This USB device is not designed for industrial applications and can easily be damaged in the situation you described. For a USB device with a greater ability to withstand this type of power surge, you should watch the box USB-6525. A better solution would be a CompactDAQ or CompactRIO system with a NI 9401, which is designed to withstand 1 000 V_rms, verified by a 5 s dielectric withstand test.

• AO. MaxRate, AO. MinRate, AO. Properties of voltage. RNGs for hardware DAQ USB-6008

  Hello

  in one of my report, I use the AO. Property of Voltage.Rngs to see if the selected DAQ card takes in charge the application voltage range. This works very well for my PCMCIA card as well as a PCI card. Now run the same VI with a USB-6008 device, this property gives all the return values. In addition, the report of AO.max.rate and AO.min.rate of the '0', the output is-200197 error properties. I use DAQmx as it is supposed to support the same functions for all DAQmx devices. Can someone please tell me what wrong here and how can I get around this?

  Best regards

  Gabs

  AO.min.rate and AO.max.rate are 0 and error-200197 back because the USB-6008 case supports the outputs analog hardware timed.  The description of error is "device does not support this property."  There is an entrance to the knowledge base for this question.

  By selecting 'Use Waveform' uses the synchronization of the sample clock.  The waveform data type specifies a delta t, which is used to set the sample clock frequency.  It is not supported on the box USB-6008.  You shouldn't set your calendar of sample type or explicitly assign the "On Demand".

  The DAQmx driver supports hundreds of different devices.  Not all combinations of properties are valid for all devices.

• Lack of external input clocked with USB 6008

  I'm a little confused on how to extract digital data without an external clock.  I guess that there is a way to do it, or this device would not do any digital input advertising, but I don't understand exactly how that would work.  Apparently, my only option is ' we demand. "

  I take data frames occurring about every 1 ms with a frequency of 950 kHz clock.  I have this completed with a more sophisticated Board using a clock from the data source.  We now want to translate this to the USB-6008, so we can use the 6008 OEM like a daughterboard for our data source.

  Avoiding him depends on the software you use, the pc, the os, etc. Whenever you want to do a reading of a line, you do a Read DAQmx. Absolutely no correlation with a time given because windows is not even close to deterministic. You may have readings in the low khz range.

• Data acquisition with USB-6008 using C++

  Hello

  I am trying to use USB-6008 to collect analog data without using Labview, since I can't afford the lincence. I searched in the C++ provided with product samples and found "Simple example of analog input.

  The compiler I use is codeblocks instead of visual studio (once again for monetary reasons). The code seems to works since when I run it with the USB-6008 box connected, he wrote "gains 1000 points.

  I have 3 questions relating to the use of this code:

  1. where are stored the 1000 points?

  2. How can I modify the code to specify the time acquisition and the frequency of acquisition?

  3. How can I change this code sample points simultenously with 8 analog inputs?

  Thank you for your help,

  I'll try to add any clarification if necessary.

  Albany

  Your questions are answered in help for c programmers.

  1000 points are in the variable array of points called 'data '.

  The sampling frequency is set to sync.

  The number of points read is defined with the function of reading.

  Read channels are defined with the function channel set. To read multiple channels, use syntax such as Dev 1 / ai0:3 for the first 4 channels.

• Frequency of maximum output with USB-6008

  I have a digital circuit containing 3 exits, 3 inputs digital and analog 1 entry in labview with my USB-6008. When I connect to the entrance (via the DAQ assistant) analog, the output frequency is reduced to a maximum of 27 Hz, but I need 50 Hz. is possible to do?

  Ah.  You'll need a DAQ better than the 6008, to do.

  There is no train generation feature buffering or the pulse on the 6008.  The outputs are all timed by the software, you cannot build a table and tell the 6008 in the output array.  Out of the 6211 must be able to produce this signal.  Series X-series Renault will do what it takes; the USB-6341 is probably your best option.

• Incorrect value for analog output USB-6008. Cannot not out more than 3V

  I use USB-6008 analog IO, but the analog output (AO0 or AO1) can go up to 3 - 3.5V. The output can follow accurately the value of 0 to 2, 5V, but then he start the values adjusted trolling and not can not spend you 3.5V exponentially.

  The only strange thing the entire circuit is that I connected all patterns (analog source and I/O 5V) between them, but I don't see what affect the output.

  Kind regards

  Thanks for the quick reply Ana.

  It is not the Council NOR, nor the Council of motorization. Apparently, the interface for motor control (motor spirit C: solutions - cubed.com), load the analog output. A tension following actually isolated op amp output USB-6008 and solved the problem.

• Burning DVDs for playback with a DVD on a TV

  I have vista and I tried to do with the creation of dvd and through windows media player and when I put in the dvd player, it says error disk... read function are not available for this disc. they are dvd + r and the mp4 files if that makes a difference. I tried in many ways with three new discs and now know that they are not erasable, so I just lost three discs! Help please!

  Hi Cindy

  Unfortunately creating DVD discs on pc for play on a standard player is not so simple that you hope... the link below will give you an idea of the process and requirements. You will also need some DVD(+ or-) RW disks so that you can erase and start over if things go wrong...

  Take a look and if you want more help let us know... Cordially - Ric.

• Should you cuda for playback with 4 k on Macbook pro end of 2013?

  My question is, I have a macbook pro (late 2013) i7, 16 G of ram, nvidia Gforce 750 m with 2 GB of memory ddr5, mavericks osx 10.9.1

  Is this reading machine 4 k with only the software? or he must have active cuda?

  Because I did several tests first with RED 4 k files and even with a resolution of 1/4 I always drop frames. Then I tested with Arri Alexa 2 RAW files k and first just may have a reading decent regardless of resolution 1/2 gal and droped frames, 1/4, this is a no go because there a lot of pixels can't really see it happening.

  Another test was 4 k IOS Canon 1 d files. These files are still similar to the arri those, I do not have a reading no matter the resolution! These files, I can't even play on VLC they lag everywhere.

  I handled the files on the flash drive SSD internal 700MB read/write, and then in a lacie us3, same problem. On the first with the software alone and cuda, same thing.

  (I already posted on a diferent discussion, im having droped frames with cuda on simple H264 files enable, then maybe for 4 k is possible, but only when the cuda option works perfectly)

  If its a problem with my computer, or you guys think its first Adobe CC?

  Thank you

  
  

  CUDA does not at all help with reading.  It helps with effects, graduation, blend modes and other.

  For this kind of media, you should really focus on a proper workstation with five internal drives:

  System

  Projects

  Cache / Scratch

  Media

  Exports

  And you might want to consider making this Media Player a RAID 3, which means a minimum of seven internal disks.

• Measures of true bipolar voltage with USB 6008/6009

  The 6008 or 6009 to make true bipolar (positive and negative voltages referenced to GND) measurements?  If not, what is the solution to purchase cheaper data this feature?

  Thank you.

  The question of unipolar vs bipolar vs bipolar Pseudo-aleatoire also was mentioned in this thread.  The 6008 6009 use bipolar-only mode and load the setting differential input or CSR.  Please note that {unipolar / bipolar / Pseudo-bipolaire} is independent of {differential / CSR / Pseudo-differentiel}.

  The 6008/6009 don't use 'Pseudo-bipolaire', which means that each differential input should be positive with respect to the ground.

  Best regards
