4. In case of using a digital servo (300 Hz command signal frequency) tick Digital
check box and click Set button.
5. Click 'Set min' to move the servo to its predefined minimum position and change
the value on the box to move the servo to a new position.
6. In case the servo is not moving on the desired direction tick on Inverted check box
and click Set button.
7. Repeat the step 5, for neutral and maximum positions.
8. Press Set button to record the three values.
9. Open Save Changes on the Settings menu.
10. Press Yes to record the new values on the Autopilot.
Note: The throttle servo only accepts maximum and minimum values.
2.12.7.1 2.12.7.1 Adjusting a servo controlled Camera
If you system has a PWM servo controlled camera installed these steps should be followed
to adjust it properly:
1. Configure the correspondent servos for maximum, neutral and minimum
mechanical travel as indicated in section 2.12.7 “Servos”. To determine the proper
setting of the “inverted” checkbox consider:
a. Pan servo should point the camera to the right when in maximum position and
to the left in minimum position
b. Tilt servo should point the camera down when in minimum position and up in
maximum position.
c. Roll servo should rotate the camera image frame clockwise when in maximum
position and counter-clockwise when in minimum position.
2. Set to neutral the pan, tilt and roll servos. (Camera should look straight ahead)
3. Command Min position in pan servo (Camera should look to the left of the vehicle)
4. Measure the angle between the line of sight of the camera and the forward
orientation.

Minimum, neutral and maximum values are reported in µs. Internally, the
autopilot uses a different representation of servo adjustment, so it is
possible that sometimes a different number than the input may be
reported. E.g. input 1500µs and 1499µs is reported. This is normal and
expected behaviour.
Be aware that servo adjustment mode commands each servo
independently, so, for systems that must respect some mechanical
restriction between servos (e.g. a helicopter swashplate with a 4 servo
configuration) it is very recommended to release the quick link to avoid
damaging the servos.
Advanced servo parameter configuration has been supported in the
autopilot since march 2014. Autopilots with firmware produced before this
date won't answer to the “Advanced mode” Get button. When in this case,
restrain usage to the simple version.
