Product Usage Instructions

Connection
Connect the VTX to the camera and the flight controller as shown in the diagram below:

• Red Wire : Power
• Black Wire : Ground
• Yellow Wire : Video
• White Wire: UART

Linking
Follow the instructions provided to link the VTX with the goggles and remote controller.

Upgrade
Ensure your firmware is up to date by following the upgrade instructions provided by the manufacturer.

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

1. Below is the wiring diagram of the 4-pin cable to the flight controller (take the Diatone F405 as an example).
2. Connect the flight controller to the Betaflight Configurator, and open the Configuration tab. Turn on the UART in an example in the figure. Check MSP with other OSDs.

Below is the corresponding port setup (Take the UART2 as an example in the figure). Open the OSD tab and set the OSDs. Check the VTX (MSP Displayport).

2. Fan
3. Serial Port Pad
4. Power Port
5. Link Button
6. Micro SD Card Slot
7. VTX LED
8. Antenna

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

1. Connect the VTX and the power of the goggles.
2. Short press the VTX and goggles linking buttons respectively, when the VTX enters the pairing state The VTX LED turns red, and the goggles end is a DI … DI. .. DI …
3. 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.

1. Copy the upgrade file to the VTX Micro SO card directory, connect the power supply and wait for the device to start up (if there are old firmware flies, please delete them).
2. 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)
3. After the upgrade is successful, the VTX indicator turns green and blinks.
   The Avatar GT TF card slot does not have a rebound function Please stick the PVC sticker to the TF card before inserting it.

UART

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

1. Solder the white and gray wires of the 4 pin cable to the flight controller (refer to the Connection page).
2. 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.
3. 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

1. Open the corresponding uart port (Take uart1 as an example in the figure) Check the MSP switch and click Save, Check the VTX (MSP+Displayport).
2. Open the CLI command line and enter the content in red font, “save”

Precautions

1. Before powering on, please install all antennas to avoid damage to components.
2. 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.
3. If you use it with other 5.8GHz devices at the same time, please choose a different channel.
4. 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.
