Right mono camera stuck at really high exposure

jingnan

Hi team,

For one of our cameras (OAK-4-D-FF Serial number 1107408872), the right mono camera was stuck at really high exposure. We reflashed the OS and the issue was not resolved. Curiously, this happened after testing with FSYNC adapter.

Oskar-Luxonis

Hey jingnan - please disconnect the FSYNC adapter/cables completely, power-cycle the device, and test again with a basic mono preview. If the right camera still looks like this, please contact support@luxonis.com with the device serial number, Luxonis OS/DepthAI version, and a log so we can investigate it as a hardware-specific issue.

Thanks,
Oskar

jingnan

Yes we've tried power cycle, reflashing OS and test with OAKD viewers. How do I access the diagnostic logs?

Oskar-Luxonis

Hey jingnan - thanks for confirming. Before we escalate this, could you please test with the v3 cam_test.py utility, with the FSYNC adapter fully disconnected?

This will show both mono streams and print the exposure and ISO for each camera. While it is running, please press i/o to decrease/increase manual exposure and k/l to adjust ISO (e returns to auto exposure). These controls apply to both mono cameras; please let us know whether the right stream responds to the changes, and share a screenshot plus the CLI output.

Thanks,
Oskar

Please see the screenshots (first two adjust exposure time, last two adjusting ISO). It does change the brightness but the right camera is still stuck at a really high exposure.
