3. Correct Installation of NI myDAQ

If you are unable to communicate with the NI myDAQ, complete the following steps to verify that the NI myDAQ is successfully recognized by the computer. 

Note: Before starting this process, close all NI software completely.

  1. Plug the NI myDAQ into an available USB port and check that the blue power LED lights.
    1. The LED is on: the NI myDAQ has power. Proceed to step 2.
    2. The LED is off: the device is not being powered. Try using a different USB port on the computer, a different USB cable, or a different computer. If the power LED still does not light, contact Studica to replace or repair your NI myDAQ.
  1. When plugging in the NI myDAQ in step 1, note whether the NI ELVISmx Instrument Launcher automatically launches.


    1. The NI ELVISmx Instrument Launcher loads: the driver software recognizes the device. Proceed to step 4.
    2. The NI ELVISmx Instrument Launcher does not load: the system may not recognize the device. Proceed to step 3.
  1. Verify that the device dislays in Device Manager.
    1. Launch the System Properties dialog by right-clicking My Computer, then selecting Properties.  


    2. On the Hardware tab, click the Device Manager button. In the Device Manager dialog that opens, look for the NI myDAQ device entry, usually located under Data Acquisition Devices.
    3. Check the icon for the NI myDAQ device:
      1. NI myDAQ is present with no errors (as shown): proceed to step 4.


      2. NI myDAQ device is not present: Ensure that both ends of the USB cable are securely seated, then right-click the computer icon at the top of device manager and select Scan for hardware changes to check for the device. If it is still not present, try using a different USB port, USB cable (if available), or computer to narrow down the cause of the problem. If the problem still persists, contact Studica to replace or repair your NI myDAQ.
      3. NI myDAQ device is present, but with a red "X", yellow "!", or as an unknown device: right-click the NI device entry and select Update Driver from the shortcut menu. After Windows finds the driver automatically, restart the PC to finish the driver installation. If the device still does not appear correctly in Device Manager, reinstall the NI-DAQmx driver, then try again. If the problem still persists, contact Studica to replace or repair your NI myDAQ.

  1. After the device is recognized by Windows, you can use the NI myDAQ Troubleshooting Utility to diagnose any problems with the NI myDAQ device
