• My acquisition of data NOR usb-6008, does not appear in labview after installing drivers

  My DAQ does not appear in my labview program after installing the drivers. I can't add it to my program or anything like that. I installed 3 different drivers and updates, and it's still not appearing in labview. Is there something I'm missing or need to do yet?

  Thank you

  It seems that you have a damaged file somewhere in your installation.  You will need to go into the control panel and select the option to repair the installation.  You will need to run the repair twice due to a known problem.  After that, you need to reinstall the NI_Daqmx 9.4.

• Simultaneous to the AO and HAVE with the acquisition of data NOR USB 6001/MATLAB Toolbox

  I am very new to data acquisition and bought a NI USB 6001 to start to learn. Because I can get free MATLAB through my University, I use Matlab data acquisition Toolkit as the data acquisition software.

  My problem is that I get the following error message when I try to generate an AO (an LED voltage) signal and measure a signal I (voltage of a battery of 9V) simultaneously.

  ATTENTION: This change is caused in the dump output data queue.  Use queueOutputData for the queue data before the start of the object.
  Hardware does not support the specified connection. Check the user manual of the device for the valid device routes and pinout.

  However to measure IA or by generating the AO each by themselves works perfectly well.

  My Matlab script looks like this:

  daq.getDevices;

  s = DAQ.createSession ('or');

  s.Rate = 1000;

  s.DurationInSeconds = 10;

  addAnalogInputChannel (s, 'Dev1', 'ai0', 'Voltage');

  addAnalogOutputChannel (s, 'Dev1', 'ao0', 'Voltage');

  aoVoltage = 1.8 + 0.1 * sin (linspace (0, 2 * pi, 10000))';

  queueOutputData (s, aoVoltage);

  s

  startBackground (s);

  Note that adding the channels HAVE and AO at the session also works, however I get the error mentioned at the start of the session. This is a limitation of my data acquisition hardware (I don't see something like that mentioned in the manual) or do I have to modify the script?

  The pins connected for the LED are AO0 (+) and AO GND (-).

  The pins connected to the battery are AI0 (+) and (-) AI4. (The problem is still there if I use the reference to the ground for AI)

  6001 cannot make simultaneous tasks.  Very standard limitation of the low-end hardware... just don't have on board computing resources to handle such things.  Even the 621 x boards have only limited multitasking abilities.

  Can intensify to a high range data acquisition ($$$) or buy a 2nd a low end and synchronize tasks in software (not as precise calendar).  I've done two approaches, one is "best" really depends on demand... If low-cost or high-performance is a priority.

• ACQUISITION OF DATA NOR USB-6251

  is it possible for the box USB-6251 to provide an output for a test set-up during playback of the inputs of the device even? for example: 10VAC Ridge to Ridge on the luminaire, mixed the sine and square wave signals of the luminaire to the data acquisition Toolbox.

  Yes. The 6251 has two outputs analog and 16 analog inputs. Open finder example and looking for examples of both. Under input and output hardware > DAQmx > Syncronization > multifunctional, it is an example of analog inputs/outputs synched.

• fiber optical sensor su19 110 115 a 126 vs nor usb 6008

  Hi expert... I am looking for idea or help on my project. I try to get the measure of mention nor USB 6008 sensor output. In fact, I'm new with nor peripheral usb n still study n the search on internet or n. forums I found an idea to connect the sensor by aoi, but I can't seem to get a measurement any. Is the sensor can connect directly to the device usb or need some custom wire diagram between them. Thanks in advance

  First of all, it is useful if you name the manufacturer of the sensor. A single part number means nothing to most of us.  You use the sensor fiber-optic Pepperl + Fuchs? Even better is to display the technical/manual plug of the sensor or links to them.

  The data sheet that I found for the sensor to Pepperl + Fuchs is not very well written, in my opinion. It seems that the outputs are impulses with dependent amplitudes of the voltage and the frequency or the timetable set by the mode of operation.

  If it's the device you use, the only way you have any possibility to decode the outputs with the USB-6008 box is to measure with an analog input and then process the data in the software. According to the supply voltage, you will probably need a voltage divider to reduce the output voltage of the sensor to a level compatible with the DAQ hardware.  You also won't be able to use the high speed of the probe because the heart rate exceeds the Nyquist limit. In standard mode, you mighte be OK, but you can use a single channel of the USB-6008 to stay in the Nyquist limit.

• NOR-USB 6008 Matlab Mac OSX

  Dear NOR-Experts,

  I wasn't sure which Board to post my question, so if this isn't the right place please accept my apologies. Be a too-unskilled computer user, I tried in vain to approach a converter A/D of NI USB-6008 of in MATLAB R2012b on a Mac OS 10.8.3 for quite a while.

  Searching through the internet (http://www.binghamsite.com/miscellaneous/matlab-mex-and-ni-usb), I learned that the General path to follow is to use the mex from MATLAB command to compile code written in C in the programs included by MATLAB. By following the instructions provided on this site, I ran mex - configure, edit the mexopts.sh file and was able to compile the file simple timestwo.c for test purposes.

  I then tried to do the same for the data acquisition example .c files provided with the package OR-DAQmx Base (3.6 v). I have been informed that mex objects require the inclusion of the header of NOR-DAQmx Base (NIDAQmxBase.h), so I tried to run

  MEX - I ' / Applications / National Instruments/NOR-DAQmx Base/includes ' acquire1scan.c

  Compilation fails producing a lot of information, I do not understand (see attached file). However, the error messages

  "Error: this platform is not supported, because long is not 4 bytes." or

  "Error: this platform is unsupported because int is not the same size as long."

  appear repeatedly. My Macbook uses an Intel Core i5 processor that is 64-bit, if this may have something to do with it.

  Any suggestions on how to get this race would be very appreciated.

  Thank you

  Robert

  Hey, Robert,.

  I think that MATLAB 2012 for OS X is a 64-bit only application, which will not work with 32-bit data acquisition Base driver.  There may be older versions of MATLAB who have a 32-bit version on Mac OS X, it would probably work with the method described in your link.

• How can I improve the rate of acquisition with daqmx and usb-6008?

  Hello

  I am trying to acquire data of analog voltage with a USB-6008. I'm under Labview 8.5 student on an HP laptop with a 1.33 Ghz cpu and 736MB RAM, apparently. I tried using the Daq assistant and the low-level Daqmx functions. My best results come with a task set in MAX for my analog input, and using the function 'Daqmx read' the 'unique double 1 d sample' value in a while loop. I insert the values returned in a table which built in the while loop, and then when I'm done, I check the number of samples in the table. In the test VI attached, I also use the time to Get before and after all loop. The best sampling rate I made using this method, is around 40samples/second. I have attached a VI below that illustrates this concept. In my actual application, the data acquisition code runs at a time while loop with 1ms, parallel to other code that controls the device I'm collecting data of. The sampling rate is roughly the same for my test below VI and my application program.

  The 6008 datasheet gives the sampling frequency maximum 10 kHz. I'd be happy with 2 to 2.5 kHz, or as soon as possible; I'm sure that I can achieve a little more than 40 Hz. My first idea was tied to the hardware, but the 6008 cannot make acquisitions NI hardware.

  My question is: How can I implement a faster sampling of analog voltages to a USB-6008 in LAbview? If I can't do it, is there another way I can taste the data more quickly?

  Thank you

  -SK-

  

  To the best of my knowledge, the USB-6008 can do timed equipment acquisition. Don't forget that this is a multiplexed device, so if you add 8 channels so the maximum you can set is 10 k/8

  If you are new to LabVIEW, I suggest that you try this sample program first

• NOR-USB 6008 and Red Lion Cub5

  I have a USB-6008 attached to an AXL32 chip for recording of analog voltage and want to add a Red Lion Cub5 counter to display the number of the sample.  I want my labview program to drive the coutner via digital output, so that I can see what sample of data occurs.  There is a setting TTL on the Cub5, but I can't seem to increment the meter through the test DAQmax Panel.

  Troy,

  I'm glad to hear you got everything and functional. I suggest you mark a message as accepted solution so that other people can find solutions to a problem easier. Thank you.

• Delay in acquisition phase data between two lines connected physically on the acquisition of data NI USB-6289

  Hello

  Currently, we have two signals which are physically and logically linked together on the same line of data acquisition. The first, 'I' and the second signal, 'Q', are both related to "Ai6" (PIN 23) and "Ai GND" (Earth). However, when we probe the two lines coming our function "signal split", I drove Q by about 0.5ms. My question is, if these two lines are actually bound together physically and logically, then why are they phase shifted if they are both the same channel? They should be exact matches. I thought that the phase delay inter-channel occurs only in what concerns channels being read from data acquisition. I have attached a few screenshots as well.

  Input signal is 20 kHz. Sampling rate is 40.5 kHz, number of samples/point is 1000.

  Thank you.

  Best,

  Saami

  System - Ultrawave Labs engineer

  The board you are using is a multiplex.  If you create several virtual channels, pointing to the same physical channel, we can enjoy this channel once for each channel.  So what's happening essentially is that the physical channel was sampled once for channe 'I', then again for the channel 'Q' with a delay of a few milliseconds in between.

• Acquisition of data NOR-9205 Assistant set up range of input voltage

  How to configure the module NI9205 to use the +/-200mV input range.

  I use a custom scale, and it seems that I can not get an accurate reading.  I use a shunt current of 100 Ma (max 10A).  So I custom balance setting to have 100 x + b.  The current flowing in the device is 2 amps and I get a reading of 12-13 amps after custom scale.  Now I think the module is configured to sample for the entrance of 10V and I get an error of resolution.

  Hi therbert

  Since your custom scale is 100 x, to work on the beach of +/-200 mV to your NI 9205 module you must configure your input signal of maximum and minimum range for +/-20 respectively.

  According to the equation: Range.max * scale.slope = 200mV * 100 = 20V

  This will automatically configure to the scope of the module +/-200 mV to verify you can access the channel DAQmx property node and look for the analog input > General Properties > advanced > Range property, this will let you know in what range is the functioning of the device.

• BlackBerry 8700 g smartphone keyboard strange problem: typed letters do not appear on the screen

  I support two users of 8700g.  Too, I am a user of 8700g and have not experienced this problem: randomly and intermittently, the report to the users when they type messages on the keyboard, strange combinations of letters appear instead.  There is no apparent trend to which the keys are depressed, what order they are in a hurry, or what appears on the screen. This, too, is random.  This aggravating problem appears and disappears at will, if the battery is removed or not.  Two units, one is new from January 2008, while the other has had some exposure to water and has been deleted twice, once for the same weird keyboard problem.  The selected language is English and the automatic text is disabled on both units. The other units are working according to specification.  We are on a BES using MS Exchange. I read on other boards sometimes there are identifiable patterns in what is indexed and what appears, but I was not able to establish such motives with these users.  Can anyone offer a diagnosis and a permanent solution?  Thank you.

  Thanks, bifocals, for your reply!  Memory is a problem, but especially a recognizable model has emerged so that I can identify and solve the problem: when the user has typed 'a', they got 'on' and when they typed 'no', they got "pt no pot"-which I have learned are caused by the input accidentally language be changed to Català.  I learned through this and other instances of BB, the input language can be easily changed when the keys ALT and CAP are pressed at the same time, the old way of locking of the keyboard on the BB 7250.

• Consistency of the NI USB-6008 device multiple numbering on several computers

  I have some equipment that we built that contains 2 units of acquisition of data NI USB-6008 to test the product. The test software is written in C++ with NI DAQmx. Everything works fine, except that when plug us the test on another PC, the two units DAQ hardware get their reverse numbering system. This means that what was 'Dev1 ai0"on one machine becomes ' Dev2/ai0' on the second machine and vice versa. We have only two machines, we are working on – is it possible to configure the hardware to enumerate identically on both machines? Or do we need to identify the two Renault by any other method?

  Thank you

  What happens to Colby,

  Welcome to the forums and thanks for your question.  There are two different ways that you can ensure that you always reference the same camera.  The devices list in your system in the order that they were added, so the first way would be to always plug in the same order.  This isn't really the most reliable way to do things, so you can use the nodes property DAQmx.

  Now, I hope you will forgive my text based on coding is terrible, but the functions you need are DAQmxGetSysDevNames() and DAQmxGetDevSerialNum().  I'll leave the coding to you, but the Names property will turn all of the devices in your system.  You can then pass these and get the serial number of the device that will never change.

  For LabVIEW users who come on this post, here is what your code will look like:
  

  You will want to be aware that this second approach will not work if you have an OEM application where all devices that you deploy will have a different serial number.  I hope this helps.

• How to connect dwyer SERIES 629 differential pressure transmitter to the acquisition of data 9219 and read the signal?

  Here is my sensor
  Pressure sensor

  Here's the DAQ data sheet:

  ACQUISITION OF DATA NOR 9219

  Here are my issues:

  First of all I don't know what is LO and HI exactly in the DAQ 9219 material.

  Second, I don't know what pin code I should connect the DAQ sensor signal wire. PIN 4 or 5 pin? The sensor has three pins, and I guess I should connect the other two wires to the power supply.
  Thirdly how to calibrate the sensor. In labview choose voltage in the wizard?

  I'm pretty new in this acquisition of data and I need your help.

  Thank you

  Hi SilasIII,

  Hmm well 3 sons are probably on the ground, the power and the return signal. The datasheet for the sensor says:

  

  First of all, you need to know which model you have (4-20mA, 0 - 5V or 0-10VDC). HI refers to the return signal, LO essentially means the land of the food that feeds the sensor. Then, you must get the 13-30 VDC supply. I don't think this should be too complicated and can be a simple wall DC power. You can learn how to create a custom in DAQmx scale. I hope that this is a starting point.

  Kind regards

• Looking for a way to mount an acquisition of data USB-6008

  Anyone has a suggestion for an acquisition of data USB-6008 mounted on a Panel. I use it for a system where it should not be loose. I have a few ideas, but hope that someone smarter already has a good solution.

  Thank you

  It is not a robust application, but the box will be moved and I don't want it put in the open air. I simply put a velcro pad on the back and the atttaching in this way. Should be all I need.

• 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.
