Troubleshooting acquisition reliability issues
A number of factors can cause acquisition reliability issues. You can use the Aurora Imaging Capture Works utility to determine if you are having reliability issues. In this utility, select a camera and start the acquisition. Then, select the Acquisition Statistics tab. This tab will show whether any acquired frames (images) are corrupt as a result of missing packets. The bottom of the Acquisition Statistics page contains the last frame that reported an error, along with error codes that can help in diagnosing the issue.
The following is a list of the common causes of corrupted frames:
- Your Gigabit Ethernet network adapter is not well-suited to your GigE Vision camera's bandwidth requirements. Use a high-bandwidth Network Interface Card (or a Zebra GevIQ frame grabber).
- Your network adapter settings have not been adjusted for GigE Vision acquisition. You need to adjust your adapter with recommended settings.
- A network device between your GigE Vision camera and your network adapter, such as an Ethernet switch, is dropping packets. See the Using an Ethernet switch with GigE Vision cameras section.
- The total bandwidth of all GigE Vision cameras streaming image data to the same network adapter exceeds its link speed.
- An insufficient inter-packet delay.
- Your camera does not have the packet resend capability.
- Your Ethernet cables are not rated Category 5e (Cat 5e) or better.
