Updates in Cortex 6.2.3 since the Cortex 6.0 Release

Camera Software Updates

Kestrel camera software update:( increases the overall usability of the camera, helping it see markers further. This camera software also resolves an issue found with some Kestrel cameras that would cause the camera to not boot initially. Please note that this update may require tuning of the aperture in order to compensate for the increased brightness of the image.

Raptor-12HS (High-Speed) camera software update: ( replaces the Cortex 6 release version of the camera software that would potentially cause some cameras to forget their settings.
We do not recommend customers use the original Cortex 6 camera software for Raptor-12HS cameras.

If you have either of these cameras, we recommend updating your camera software. Updating your camera software will improve functionality by allowing you to use the full potential of the camera with the new Cortex software. To update your cameras software go to the Setup –> Cameras tab and select “New Camera Software…“
