Connection

Power consumption: 12V@1.5A Please consider the power supply capability of the power supply.
VTX generates a lot of heat when working, so please pay attention to airflow for heat dissipation

Linking

Connect the VTX and the power of the goggles.
Short press the VTX and goggles linking buttons respectively, when the VTX enters the pairing state The VTX LED turns red, and the end of the goggles is a DI… DI… DI…
After the link is successful, the indicator light on the VTX LED turns solid green, the beeping sound on the goggles stops and the screen is displayed.

Upgrade

Please go to the official website to download the upgrade firmware,
Avatar_Sky_X.X.X.img is the VTX file, be careful not to change the file name.

Copy the upgrade file to the VTX Micro SD card directory, connect the power supply and wait for the device to start up (if there are old firmware files, please delete them).
Press and hold the VTX linking button for 8 seconds, and release the button after the indicator light goes out. At this time, the VTX will automatically restart and enter the upgrade state, and the indicator light will change from blinking red to solid red and then turn off. The upgrade time is about 20 seconds, please do not power off during the upgrade process! (If the VTX continues to light up red, it means that the firmware cannot be detected or the firmware is wrong, please check the firmware file)
After the upgrade is successful, the VTX indicator turns green and blinks.

UART
The UART function enables the VTX communicate with the flight controller, allowing the VTX obtain the flight controller information. Take Betaflight Configurator as an example to introduce the UART setting method.

Solder the white and gray wires of the 4 pin cable to the flight controller (refer to the Connection page).
Connect the flight controller to the Betaflight Configurator, and open the corresponding UART port (Take UART1 as an example in the figure) Check the MSP switch and click Save.
Open the CLI command line and enter the content in red font “set osd _displayport_device = MSP” “set displayport_msp_serial = Y” (Where Y is one less than the number of the serial port. e.g. Y = 2 for serial 3) “save”

Betaflight 4.4 or above version settings:

0pen the corTesponding uart port (Take uart1 as an example in the figure) Check the MSP switch and click Save, Check the VTX (MSP+Displayport}.
Open the CLI command line and enter the content in red font,set osd_displayport_device = MSP” “set vcd_video_system = HD” save

Precautions

Before powering on, please install all antennas to avoid damage to components.
When the standby mode is turned on, the power is limited to 1 OmW. Before taking off, you need to unlock the flight control or tum off the standby mode.
If you use it with other 5.8GHz devices at the same time, please choose a different channel.
If you use the Gyroflow function of the camera, please provide shock absorption for the fixed deck of the camera to avoid the failure of the anti-shake.
