The Imaging Source cameras

There might be problems with image acquisition from The Imaging Source cameras through GigE. It's caused by the implementation (regarding caching and packet size) of GigE Vision standard in those cameras and as a result no image can be seen in FabImage Studio (the previews are empty during program execution).

To resolve this issue, a camera restart (this has to be done only once, after you encounter the problem with image acquisition) and changing some parameters in FabImage GenAPI configuration are required. Parameters which should be changed are:

  • Enable GenAPI Cache (should be set to False),
  • Disable Packet Size Negotiation (should be set to True),
  • Enable Constant Packet Size (should be set to False).

In order to change these parameters, you should (before opening device connection) open library configuration with function GigEVision_OpenSystemConfiguration, and set the following parameters (please note that these parameters have to be set separately for each application)by using GenApi function:

  • GevAppTLEnableGenApiCache (Boolean) to False
  • GevAppTLDisablePacketSizeNegotiation (Boolean) to True
  • GevAppTLEnableConstantPacketSize (Boolean) to False

Basic Troubleshooting

If a GigEVision device is connected, but the image cannot be acquired, please follow the steps below.

  1. If the camera settings have been changed, set the default value for each changed parameter.
  2. Check if there is no other software that uses the camera in the background. If there is, close it.
  3. Check the camera connection. Connect the device directly to the PC if possible. If not, simplify the connection as much as possible. If there is any managed switch, check its settings.
  4. If possible, use stable power supply (not PoE).
  5. Set static IP address for both the camera and the PC. More information can be found here.
  6. Enable Traffic in Firewall. More information can be found here.
  7. Turn off Third-party Network Card Drivers. Third-party Network Card Drivers
  8. Enable Jumbo Packets. More information can be found here.
  9. Update PC Network Card Driver.

If after following all the steps the issue still appears, open GigE Vision Device Manager, right-click on the issued camera, choose Save Device Diagnostic to File, and send the created file to the Technical Support Team.
