I successfully installed a DataMan reader and it was working as expected. Suddenly, no images are shown anymore in the Setup Tool. What is causing this?
Answer
In many cases, this issue occurs when the Network Client option is enabled in the Ethernet communication settings.
If the connection to the configured server is unavailable, the reader will continue to generate results, but cannot send them. These unsent results accumulate in the output queue.
Since every result is linked to a result image, each queued result occupies one image buffer. As the queue grows, all available image buffers eventually become filled.
When no free buffer is left, the Setup Tool cannot retrieve or display the latest images.
How to resolve the issue:
- Verify that the Network Client feature is actually required for your application.
- Ensure that the server connection is active and correctly configured.
- If the feature is not needed, disable it to prevent unnecessary queue buildup.
Once the connection is restored or the Network Client is disabled, normal image display will resume.
