2. Choose System > Update Firmware.
3. Select the file DM8600_v.5.4.4.bin.gz or newer from the directory where the firmware update automatically navigates (Cognex\DataMan\Firmware\DM8000 Series).

To enable the DPM Verification feature, you must upload a feature key file to the reader:

1. Connect the reader to the DataMan Setup Tool.
2. Choose System > Upload Feature Key.
3. Select the feature key file that you received from Cognex.
4. The reader automatically reboots after the upgrade and it is ready to use for verification.
