Troubleshooting GigE Vision Devices on Linux

If you are having trouble using the Image Acquisition Toolbox software with a GigE

Vision camera on a Linux machine, using the toolbox's gige adaptor, follow these

troubleshooting steps:

With previous versions of the Image Acquisition Toolbox, the files for all of the

adaptors were included in your installation. Starting with version R2014a, each

adaptor is available separately through the Support Package Installer. In order

to use the Image Acquisition Toolbox, you must install the adaptor that your

camera uses, in this case, the GigE Vision Hardware support package. See “Image

Acquisition Support Packages for Hardware Adaptors” on page 4-2 for information

about installing the adaptors.

Verify that the adaptor loads. You can use the imaqhwinfo command to list

installed adaptors. The gige adaptor should be included on the list.

If it does not load, make sure that GenICam is configured correctly using the

imaqsupport function.

If your camera requires a GenICam XML file on a local drive (most do not), and the

adaptor loads but no devices are shown, check the MWIMAQ_GENICAM_XML_FILES

environment variable, and make sure it contains the directory where your camera’s

XML file is located.

For information on installing GenICam and checking your environment variables,

see “Software Configuration” on page 10-11.

Make sure you did not install your camera vendor's filtering or performance

networking driver. If you did, you should uninstall it.

Make sure the Ethernet card is configured properly.

For more information on this, see “Network Hardware Configuration Notes” on page

10-3 and “Network Adaptor Configuration Notes” on page 10-4.

Also, if you have multiple cameras connected to multiple Ethernet cards, you cannot

have them all set to automatic IP configuration. You must specify the IP address for

each card and each card must be on a different subnet.

Examine the connectivity of your device separate from using the Image Acquisition

Toolbox. You may find using ping -b, arp, route, and ifconfig helpful with this.

If you receive an error message such as:
