• Neither myDAQ

  Hello

  My PC are Win10 and I can't use the nor myDAQ (badly installed driver or Automation). The driver is present and it worked before!

  I reinstalled labview, but nothing has changed.

  Is that someone had the same problem?

  Thank you

  Thank you for your information. After investigation it turns out that:

  -LabVIEW 2012 is not compatible with Windows 10 but is LabvIEW 2015: LabVIEW & Windows compatibility

  -The NI DAQmx 9.5 driver is not compatible with Windows 10: compatibility and NOR-DAQmx driver

  I invite you to download the drivers OR DAQmx 16 ( Driver OR DAQmx 16.0 ) and install. In the MyDAQ NOR made attention to remove MAX, then install the driver and then re-connect.

  Kind regards

• generation of clock using mydaq

  Hello world!

  I just have a very BASIC question. I know that some of you may find it easy.

  Again, I'm new in LabVIEW and I try to use a data acquisition equipment NOR myDAQ. In the application, that I'm doing, I need to get a pulse generating myDAQ signal and use it as input in my multiplexer. I searched for positions and I think that none were asking such a simple question.

  If there is no solution for this, please link with me. Thank you very much!

  Kind regards

  I am afraid that I can not do. I'm only using the computer lab of the school and he removed the LabVIEW examples folder (perhaps to prevent students to access the examples during the reviews of practices). So yes... I am a student with limited access to LabVIEW.

  But I talked to the it DEPARTMENT of our school and it allowed me to download the examples instead. However, I can't find the codes available.

  Kind regards

  IMHO, he is a stupid thing, a good teacher can create easily of exercises and tasks of review to "measure" the real knowledge of the students, even if they use the built-in LabVIEW examples. A school should help during the learning curve and not by disabling the examples incorporated, but giving creative tasks...

  I've attached an example VI that will generate an output of 1 kHz by DIO-3 and DGND counter. (I tested with a myDAQ device, it works)

• Neither myDAQ oscilloscope bandwitdth

  Hi guys I m plans buy the nor myDAQ, but I have a few questions on the function i´m oscilloscope control specifications, but I anithing find can´t on its bandwitdth, thank you

  Yes I m new to this forum

  Hi Rivera25081:

  I think that what you need is the MyDAQ sampling frequency in order to know if you can measure the 3 MHz sine wave. The Oscilloscope max sampling rate is 200 kHz that means by the Nyquist theorem you can detect the frequency of a sine wave of 100 kHz. If you want a more accurate representation of a sine wave signal should be approximately 10 kHz. The signal you want to measure has a hi frequency (Radio frequency), it is necessary a faster and more robust equipment to measure this type of signals.

• myDAQ Strip connector

  Is it possible to order separately the connector for NOR-myDAQ Strip?  I have several projects for him and would like to have a band for each model so that I could leave it connected, rather than having to disconnect and reconnect the wiring whenever I pass project.

  The myDAQ OR Accessories Kit comes with two connectors 20 pins that you might be able to use.

  Could someone help me with this? I have windows 7 64 bit. I have installed 64-bit and 32-bit labview. I have NEITHER myDAQ connected to my laptop via USB. The CD that came with the kit disappeared, so I was download each disc that I could install and updated.

  Here's what I get

  All I'm trying to do, is get the myDAQ to act as a digital multimeter to measure resistance using the wires supplied with the kit myDAQ.

  I have to install a battery or something in the myDAQ? I saw a picture of the battery has a triple, but don't see any on the myDAQ battery compartment. There is a battery 9V on the myProtoBoard property, but it does not help the issue.

  Thank you

  Hi Jason,

  It seems that you have installed the legacy version of the NI ELVIS driver, which only supports the NI ELVIS device. Use an NI ELVIS II / II + or one NOR myDAQ and use the DMM feature, you will need the NI ELVISmx driver. The latest version is NI ELVISmx 4.5, which supports versions of LabVIEW 2010-2013. If you have another version of LabVIEW, let me know and I can direct you to the correct version of NI ELVISmx.

• Synchronization of the inputs and outputs with different sampling frequencies

  I'm relatively new to LabView. I have a NOR-myDAQ, and I am trying to accomplish the following:

  Square wave output 10 kHz, duty cycle 50%.

  Input sampling frequency of 200 kHz, synchronized with the output that I get 20 analog input samples by square wave, and I know what samples align with the high and low output of my square wave.

  So far, I used a counter to create the square wave of 10 kHz, display on a digital output line. I tried to pull the document according to (http://www.ni.com/white-paper/4322/en), but I'm not sure how sample at a different rate than my clock pulse. It seems that this example is intended rather to taste one entry by analog clock pulse. There may be a way to create a faster clock (200 kHz) in the software and use that to synchronize the analog input collection as well as a slower 10 kHz output generation square wave?

  I eventually have to use the analog inputs to obtain data and an analog output to write the data channel, so I need the impetus of the square wave at the exit on a digital PIN.

  How could anyone do this in LabView?

  Hi Eric,.

  All subsystems (, AO, CTR) derive from the STC3 clocks so they don't drift, but in order to align your sample clock HAVE with pulse train that you generate on the counter, you'll want to trigger a task out of the other. I would like to start by a few examples taken from the example Finder > Input and Output material > DAQmx. You can trigger GOT off the train of impulses, start by Gen digital Pulse Train-keep -you probably already use a VI like this to generate 10 k pulse train. AI, start with an example like Acq Cont & chart voltage-Ext Clk - Dig Start.vi-you'll want to use the internal clock so just remove the control of the "Source of the clock" and it uses the internal clock. From there, simply set the "Source of the command" either be the PFI line generates the meter, or ' //Ctr0InternalOutput '-assuming that you are using the counter 0. You'll want to make sure that the start of the task HAVE faced the task of counter I is ready to trigger off the first impulse. They should be aligned at this point.

  For debugging, you can use DAQmx export Signal to export the sample clock - you can then brought the train line and the PFI pulse to make sure that they are aligned.

  Hope this helps,

• Error-50303 occurred at ELVISmx_DAQmx create channel %2528AI-Resistance%2529.vi%253A1

  Hello

  I used the myDaq in my electronic class earlier today and the suspect, I have damaged the myDaq. I had an external power supply connected to my circuit on a Protoboard - the circuit was not directly related to +/-bus on the protoboard, but the Council itself was hung in the myDaq.

  I noticed this caveat statement myDaq Manual:

  Power supplies
  Caveat! Do not mix the power nor myDAQ with power of external power sources.
  When you use an external power supply, remove all connections to the power supply terminals on
  NEITHER myDAQ.

  Since then, I get the following error message when I try to take my multimeter (NI Elvismx) readings:

  Error-50303 occurred at ELVISmx_DAQmx create channel %2528AI-Resistance%2529.vi%253A1

   

  This message means that I damaged the myDaq? Could I have generated too much current with voltage circuit / applied and brought to save in the myDaq? If so, it would damage the myDaq or are there internal safeguards in order to protect the device (i.e. recognizing when internal resistance reduction) and trigger an error code (i.e. could reset you HAVE resistance)?

  I am new in the field of electronics, so please forgive me for any obvious incorrect statement above!

  Also, I went then to download the troubleshooter of myDaq - I managed to unpack the file, but it would not be completed installation (i.e. the 'next' button is grayed out on the summary screen, the only options to the choices were 'save' and 'Cancel').

  Thanks in advance for any guidance/direction you can give me!

  Sincerely,

  Melissa

  Found a miracle solution!

  Under the tools NI MAX button, there is an option to select "reset Configuration data".

  After selecting this, he reset the Configurations OR and restarted my computer. I noticed that when I reopened NI MAX, I had more options to choose when I click on the myDaq device (i.e. before I could only choose 'Save' and 'Refresh'... now I have more options including a reset, self-test function, test panels, etc.).

  I was able to use my features NI Elvis DMM and no longer see the error message (just did a simple test with a resistance).

  See you soon!

• Cannot install drivers MyDaq

  Hello everybdy. I have a myDAQ NOR am I trying to install on my computer. I don't have the installation disc, but seen on this Web page (http://www.ni.com/tutorial/11431/en/) that I can download the drivers for the myDAQ online. After you have installed the latest NI ELVISmx 15.0 drivers, I still cannot download the drivers for my myDAQ - my computer tells me that it cannot see the necessary drivers on my computer. I'm running a Lenovo Z50 labtop with windows 8.1. Does anyone have an idea as to what can happen?

  Thanks in advance

  Too bad I've sorted it now. Just Elvis has not been installed correctly on my computer

  My environment:

  8.1 Windows 64 bit running under Oracle VirtualBox Version 4.3.20 running Mac OS x on a MacBook Pro 2012 10.10.1. I have no prior exposure to work with myDAQ, LabView, or any tool of NOR.

  I downloaded NIELVIS1400_downloader.exe for Windows 8.1 to ni.com and it is finished.

  During installation I secured guarded against the problems of Win8FastStartup by stopping and restarting the PC when asked.

  After the installation when I plugged it physically in the myDAQ device, it was recognized by Windows 8.1 because Device Manager has the 'data acquisition' entries under which "NEITHER myDAQ" appears. For NEITHER myDAQ device status is 'this device is functioning.

  When the myDAQ was physically connected, the window "NI ELVISmx Instrument Launcher" popped up. I clicked on the icon 'How to set up your hardware' and the 'get started Guide... "pop up. I checked the blue LED on the device came and it is stable on. I went to "2. Paragraph confirms the recognition of the devices"in implementing on the way, guide and follow the instructions to start the automatic test. There not as described above.

  I noticed similar problems have been reported in the past. Closest to my problem reported by flex11 on 05/05/2014. Reading through I don't see any resolution itself. Another similar problem was solved by manually starting the service 'NOR device charger '. In my case, this service is already running. "NO license server" is the only service stopped, but I guess that's normal for myDAQ.

  I don't have any other product OR installed on the PC.

  I'm sure there is a simple solution to this problem, but I'm afraid it's escape. I'd appreciate any help I can get through this forum.

  Thanks for getting back to me. Your answer gave me stamina I had to move forward.

  I installed http://www.ni.com/download/ni-daqmx-14.2/5046/en/ and finally managed to do work. The exact boot sequence I need is:

  (1) delete myDAQ by USB port and then start Windows 8.1 under VirtualBox.

  (2) after that Windows 8.1 will appear, fix myDAQ on a USB port. If a pop-up window appears asking you to respond, ignore (at the beginning I did not ignore it and myDAQ transformed into a charger USB device firmware such as reported by Device Manager).

  (3) at this stage most likely "VirtualBox VM features-online USB Devices" drop-down menu shows "National Instruments NI myDAQ [0003]" as an entry but without a check mark to the left of the name. Bring the cursor to the left of the name and click here. You should now see a check mark there.

  (4) my myDAQ Self tests started working.

  However, I need the functionality provided by ELVIS as well. So I uninstalled http://www.ni.com/download/ni-daqmx-14.2/5046/en/ and installed from NI ELVISmx 14.0. My boot sequence that I have reported above, didn't work. Just at the moment it's just happened that Oracle has released Version 4.22 of VirtualBox that I wanted to try and ELVIS started to run. I can now use myDAQ DMM.

  One thing that contributed to my problems is fruitless attempts to uninstall the software OR. Unsuccessful uninstalls leave garbage behind who can or cannot cause problems in subsequent relocations. In one case, I'm done with the nidevldu (OR charger) service stuck in the system. I had to do a reset Windows 8.1 recovery operation to get rid of him. I decided to restart Windows 8.1 before uninstalling the software. This ensures that there is nothing in the limbo that past can interfere with a successful uninstallation.

• "helpasst.dll reinstall myDAQ".

  Hi all

  I'm having some trouble with Labview recognizing the myDAQ I use.

  I used a front myDAQ on my laptop with zero problems, and when I tried to reconnect, my laptop would not install the drivers correctly.

  I then uninstalled all the software of NOR and them recharged via the CD that came with the myDAQ, which did not allow the correct installation of the myDAQ because she is visible in "Device Manager".

  The question I have now is when I opened a VI, double-click the DAQ ASSISTANT to change certain properties, I get an error that reads "not found Helpasst.dll. Reinstall OR myDAQmx. »

  I followed a few steps listed in the following forum:

  http://forums.NI.com/T5/academic-hardware-products-Elvis/ElvisMX-no-supported-devices-doesn-t-see-my...

  I'm not sure what to do next.

  Richard,

  My first troubleshooting suggestion would be to reinstall the drivers for the device of myDAQ, which are called pilots DAQmx. These should update the problems of such files from the missing DLL error, you are experiencing. Here is the link for the download of the latest version.

• Windows 10 - myDAQ driver does not work

  Hello, I just "upgraded" to Windows 10 and everything for myDAQ installed and Windows is not recognizing the driver. Has anyone else had this problem and found a solution?

  I installed the latest drivers for DAQmx (15.0.1) and Elvis (15.0) without a bit of luck. I have attached the NI MAX errors and Device Manager

  Thank you very much for your help!

  Hi jtkrenz,

  Unfortunately, Windows 10 is not yet supported by Elvismx and DAQmx.  This can be seen under the OS Support in their respective Readme file:

• Creating a power supply Variable myDaq

  Hello world

  Just got my myDaq NOR the other day and just start playing with it.

  I was a little disappointed to know that power supplies were not Variable (i.e. fixed 5V and +/-15V), but that's what I have for not reading the fine print .

  I thought a Variable power supply would be a good pleasure first of all of the project, but have no idea where to start. I was hoping that you guys could give me some advice/point me in the direction to look.

  I intend to use myDaq for mainly breadboarding for laboratories after EE.

  Since the 5V power allows for the most recent shooting, I think it would be the first supply to build.

  Can someone point me in the direction to move forward?

  Thank you!

  -Ernie

  Hello Ernie,.

  Function of the desired output voltage and and currently, there are a few approaches you can try.

  Buffered outputs analog is the easiest method. You could probably get to +/-12V if you choose a small enough margin requirements with op amp and add 20% gain. You would use the +/-15V rails to power op amp (don't forget to consider the tolerance of rail), and you should limit your output to 32 spec my the +/-15v rail. The buffer is essentially a linear regulator, so be careful of the power dissipation of the amplifier at high currents.

  Output currents higher with lower voltages, consider using a switching regulator. There are a variety of topologies based on the input-output voltages. Look for Buck to withdraw to an input voltage higher than a lower output voltage; Boost to intensify; Buck-Boost to step upwards or downwards. There are others, but these are simpler to start. You can use the outputs analog of the myDAQ to inject a voltage error in the feedback from the regulator to allow programmatic output voltage control. Take a look at sellers sites power supply chip (TI, Analog Devices, Linear Tech, National Semiconductor, etc.) for application notes and recommendations from component.

  Another approach is regulatory digital switch command. These provide a detailed and read back functionality via a digital interface to the chip. Google "digital power" for ideas.

  If you need more power, you will need to provide an external power supply or battery, but control could still come from the AO myDAQ or digital interface.

  It can be a difficult exercise, but I hope this help to get you started.

• myDAQ Software Upgrade

  I am running Windows 7 Pro 64-bit and 32-bit LabVIEW 2010.  I use a myDAQ running NI ELVISmx 4.2.2 and NOR-DAQ 9.1.5.  Everything works fine.  I used this myDAQ a couple of years ago and now I need it for a new class.  I just tested the feature today and the (basically all analog for me) the measures are accurate/compatible with what I expect.

  Of course, I'll not upgrade anything if someone can tell me that NI ELVISmx 4.5 offers all of the features that my installed NI ELVISmx 4.2.2 does not work (I doubt that), so here's my question:

  I want to upgrade the software to NI ELVISmx 4.5 so that the Instrument NI ELVIS Launcher has the latest features.

  I guess I have to do is:

  1) update the firmware

  2) upgrade the software NOR-DAQ 9.1.5

  3) upgrade the Software NI ELVISmx 4.2.2 to version 4.5

  Of course, I know that the perils to assume.  But, I can't find anything that will tell me the steps needed to pass through these steps.  I need the docs for all stages.

  Can someone help me with these questions in detail the correct steps if I'm wrong and provide me links to the files I need?

  Hi rajames429,

  In order to update, all you need is to install the NI ELVISmx 4.5 which includes NEITHER-DAQmx 9.7.5.
