ESC output interface
DoS’s S1 ~ S8 ports are connected separately to ESC M1 ~ M8.
Typically 1020us is lower limit, 1520us is neutral and 2020us is upper limit, frequency is
400Hz.
4. Camera Gimbal Stabilization
DoS multi-rotor firmware,when is used to control the aircraft under 6 axis, can
simultaneously control two axis Camera Gimbal Stabilization.S7 port is connected Camera
Gimbal’s roll servo,S8 port is connected Camera Gimbal’s pitch servo.
Attention:
(1) You must use 400Hz high-speed servos for Camera Gimbal, if you use normal
servos for a long time, will cause the Camera Gimbal servos overheat.
(2) If you use DoS to control Octocopter aircraft,S7 and S8 ports will not output
Camera Gimbal control signal any more.
5. Power Supply:
●DoS input voltage is 4.0 ~ 6.0 V, you can use a stabilized voltage supply ,or directly use
ESC’s +5 V power supply, most of the ESC power supply can meet the requirements;
●DoS and the RC receiver use the same power supply via the RC receiver connection
wiring.
●VERY IMPORTANT: Only one BEC power source should be used. If all four ESCs
have internal BEC, choose only one to supply power. Disconnect the red wire (positive)
of the other ESCs,but reserve the GND and Signal wirings
