- Use a BEC to provide power to the servo as shown above
- Connect the servo's TTL pin to a 5V-to-3V level shifter and then to one of the autopilot's serial port's TX pins. The diagram above shows the servo connected to a Pixhawk's Serial4 port but other serial ports can also be used
- Set :ref:`SERIAL4_PROTOCOL <SERIAL4_PROTOCOL>` = 14 (Volz) assuming Serial4 is being used

.. note:: SERVOn_MIN and SERVOn_MAX corresponding to your Volz servo output channels should be adjusted to specify the 1000-2000 range to obtain full output range of the servo.
