Issue Details

I am using a GigE camera. When I try to configure or use it in Measurement & Automation Explorer (MAX), it shows up under Devices and Interfaces as well as the sub-category Network Devices. Which is the real one, and how do I get it to appear in only one place?


The NI-IMAQdx driver supports GIGe Vision as well as USB 2.0 DirectShow compliant cameras. If your camera supports both options NI-IMAQdx will list the device under Device and Interfaces (USB 2.0) as well as the sub-category Network Devices (GIGe Vision).

It’s highly recommended to follow the steps below to use the camera in the GigE configuration since it will allow higher throughputs and access to more camera configurations:
  1. The NI-IMAQdx driver uses DirectShow to interact with a camera’s 3rd party driver software. If you do not want to acquire through DirectShow, you will need to uninstall the 3rd party driver.
  2. Unplug the camera from the PC system and close MAX. 
  3. Delete contents of the IMAQdx data folder located under  
    C:\Users\Public\Documents\National Instruments\NI-IMAQdx\Data directory.  
  4. Plug in the camera
  5. Open MAX and verify that the camera is listed correctly under Device and Interfaces>>Network Devices.

For additional GIGe camera troubleshooting steps see Troubleshooting GIGe Vision cameras for more information.

Additional Information

In case the GigE connection displays the ‘Camera not found’ error message in MAX when clicking the Grab button. It’s recommended to contact the camera manufacturer to see if the firmware of the camera needs to be updated.

To support the latest GeniCAM standard it is recommended to update NI-IMAQdx to the latest compatible version. NI-IMAQdx is part of the NI Vision Acquisition Software driver bundle which can be downloaded here.

Note: After updating the driver NI Vision Acquisition Software needs to be activated.
