HobbyDrone GM Series Avatar Gimbal for Avatar HD System

Introduction

This product is a mechanical anti-shake gimbal that can achieve real-time anti-shake of camera images and camera angle adjustment. It is suitable for Walksnail Avatar HD system cameras with a mounting width of 19mm. GM1 can achieve anti-shake and adjustment of camera pitch angle; GM2 can achieve anti- shake and adjustment of camera pitch angle and roll angle; GM3 can achieve anti-shake and adjustment of camera pitch angle, roll angle and azimuth angle. Users need to design the mounting holes of the vehicle by themselves and adapt them to the gimbal mounting bracket. The gimbal can automatically identify upright and inverted installations.

Camera Installation

Use a Phillips screwdriver to remove the camera cover.
Use tweezers to remove the coaxial cable from both sides of the coaxial cable interface.
Install the gimbal’s coaxial cable to the camera
Install the camera on the gimbal, note that the coaxial cable needs to be placed in the internal groove
Tighten the four screws and check whether the camera can rotate smoothly to the maximum tilt angle. If there is obvious\ resistance, reinstall the camera.
The installation is complete

Connection and Use

Connect to the USB port of Avatar V2 VTX, and need to use Avatar Goggles that support head tracking to realize wireless head tracking function.
PWM1
The channel is for gimbal working mode selection, There are three working modes in total.
1. Pitch and roll keep level, and the yaw axis follows.
2. The pitch axis keeps the level, roll axis, and yaw axis following.
3. Three-axis follow.
PWM2
- The channel is for the gimbal to follow sensitivity settings. Adjust the response speed of the gimbal follow. Please use the knob channel on the remote control to control.
PWM3
- The channel is the gimbal pitch axis control channel. Please use the rotary switch on the remote controller to control it. The gimbal rotation angle range can be changed by modifying the channel range of the remote control.
PWM4
- The channel is the gimbal yaw control channel. Please use the wave wheel switch on the remote control to control it. The gimbal rotation angle range can be changed by modifying the channel range of the remote control. You can also use a third-party head tracking module to map the control channel to PWM3 and PWM4 and control the gimbal through head tracking.

Head tracking function

The gimbal supports Uart and PWM control protocols to achieve head tracking function: Uart requires Avatar V2 (Dual) VTX, Avatar V2 VTX, Moonlight VTX and goggles that support Avatar head tracking function; PWM requires a third-party head tracking module, and connects the gimbal PWM3 and PWM4 channels to the head tracking receiver pitch and direction channels. The following introduces the head tracking function settings with Avatar V2 VTX:

Upgrade Avatar goggles and V2 VTX to version 38.43.4 or above, and connect the serial port cable of the gimbal and Avatar V2 VTX according to the wiring diagram.
Open the goggles menu and select “Gimbal” for head tracking, Settings > Head Tracking >Gimbal, after the settings are completed, the gimbal will follow the goggles’ posture movements, and quickly click the return key 3 times to return the gimbal to the center.

Head tracking: Output signal selection, select PTZ.
Reset attitude angle: Click to reset the gimbal to the neutral point
PTZ Mode: The gimbal has 3 working modes to choose from.
Pitch and roll keep level, and the yaw axis follows.
The pitch axis keeps the level, the roll axis and yaw axis follow.
Three-axis follow.
Follow sensitivity: Adjust the gimbal response speed.
calibration: Do not perform calibration under normal circumstances. If the gimbal has an angle deviation for a long time, please complete the calibration of the gyroscope, accelerometer, and magnetometer according to the prompts.
Return: Exit the head tracking menu.

Upgrade

Use the upgrade cable to connect the upgrade port, connect the other end to the PC, and go to www.caddxfpv.com to download the GimbalConfig.exe software.
Open the GimbalConfig software and power on the GM gimbal.
Select the correct COM port, click Open Port, and click Open Firmware.
Select the CwGimbalZGV2Main_VX.X.cahf firmware under the same file.
Click Start Upgrade and wait for the progress bar to complete.

Goggles need to upgrade the head tracking firmware in the folder synchronously. Please refer to the manual of the corresponding product for upgrade operation.

Precautions

Be careful not to fix the coaxial cable too tightly. Make sure that the coaxial cable can move freely within the gimbal’s shock absorption range. The gimbal cannot collide or interfere with other objects when working.
When the gimbal is equipped with a Moonlight camera, it can only be used with the Moonlight VTX.
Usita the dual VAX he Avatar no function Toly supports Avatar V2 VTX,
The gimbal bracket must be fixed with the shock-absorbing ball and carrier provided in the package or by a third party, and ensure that it is firmly installed.
Uart and PWM cannot be controlled at the same time.
