PPM channels Used to set the PPM-channel pan, tilt, and roll are assigned to.

Center The center position of the servo for each axis.

End Servo travel endpoints (maximum and minimum)

Gain The gain determines how much the servo should move for a given amount of tracker movement. Default is 170 which pretty much gives 1:1 (90 degrees head-movement = 90 degrees servo movement).

All the "advanced settings"

LP filter at tilt/roll [%] Lowpass-filter of the final tilt/roll output. 1 = max lowpass/time constant. Will give very smooth, but also very slow change. 100 = lowpass off.

LP filter at pan [%] Lowpass-filter of the final pan output. 1 = max lowpass/time constant. Will give very smooth, but also very slow change. 100 = lowpass off.

Gyro weight on tilt/roll [%] How much do we thrust the gyro compared to the accelerometer on the tilt/roll axis? Accelerometer is noisy and should only be used to slowly compensate for drift. 100 = only use gyro. 0 = only use accelerometer

Gyro weight on pan [%] How much do we thrust the gyro compared to the magnetometer on the pan-axis? The gyro is a lot more accurate, so magnetometer should only be used to slowly compensate drift. 100 = only use gyro 0 = only use magnetometer

Servo pulse variation In short: Servo travel adjustment.

Used to set the max variation of the pulse-width in the PPM signal. The unit is microseconds*2 - matching the Atmega timer

Servo center In short: Servo neutral position

Used to set the center/default length of the pulse-width in the PPM signal. The unit is microseconds*2 - matching the Atmega timer

Tilt and roll gain Gain of the servo. You decide if you want to turn the head 10 degrees or 360 degrees to get full travel.

Pan gain Gain of the servo. You decide if you want to turn the head 10 degrees or 360 degrees to get full travel.

Reverse (Tilt, roll and Pan) used to inverse the servo direction.
