    When the autopilot first detects the Xacti gimbal the :ref:`MNT1_DEVID<MNT1_DEVID>` will be set to a unique number to identify the gimbal.  If the gimbal is moved to another CAN port it may be necessary to manually set :ref:`MNT1_DEVID<MNT1_DEVID>` to zero and reboot the autopilot in order for the gimbal to be found.
