• DP23 
• APX100-CAM-M 

Changes / Corrections

Firmware version 3.1.22115 corrects the following issue:

• Depending on the selected camera mirroring setting, subarrays with a height of ＜29 pixels that are either located at the upper or lower image border are underexposed (DP23, APX100-CAM-M).

Affected Cameras

Before updating the firmware, please verify the current firmware version of the installed cameras to check if a firmware update is required.

To do so, please start the cellSens™ APEX software and check the information given under Device Settings → Camera → DP23/APX100-CAM-M → Information.
To access the device settings, please open the Acquire menu → Devices → “Device Settings…”

Cameras with a firmware version lower than 3.1.22316 need to be updated.

5. Close all running applications (including cellSens APEX software)
6. Open the local SDD folder, which contains the downloaded “EVIDENT Camera Firmware Updater” ZIP file in Windows Explorer. Extract the file.

Caution:

Do NOT disconnect the camera or switch off your computer while the firmware is being updated. 

Do NOT shut down or force quit the firmware updater software while the firmware update is running.

Do NOT start/run any application software other than the firmware updater while the update is in progress.

Not following the instructions mentioned above might permanently render the camera inoperable.

Should an error message occur during the firmware update, do NOT disconnect the camera, but repeat the update process for this camera until the update is performed successfully. Close the firmware updater software and restart it before repeating the update process. Click the Yes button in step 8 if the message is shown for the camera that failed the firmware update. Do not repeat the update for other connected cameras that were already updated successfully.
