Linking

Connect the VTX and the power of the VRX.
Press the link button of the VTX and VTX respectively (as shown in the picture), when the VTX enters the pairing state The indicator light turns red, and the VRX end is a DI… DI… DI..
After the link is successful, the indicator light on the VTX turns solid green, the beeping sound on the VRX stops and the screen is displayed.

Upgrade

Please go to the offhcial website to download the upgrade firmware, AvatarsE_Gnd_X.X.X.img is the VRX file, copy it to the SD card, and be careful not to change the file name.

Copy the upgrade file to the root directory of the SD card, connect to the power supply, and wait for the device to initialize delete the old firmware file first if there in one).
Press and hold the link button on the VRX for 8 seconds, and the goggles automatically restart and emit a beep..beep.beeper sound. (Do not power off during the upgrade process, the upgrade time on the goggle is about 6 minutes)
After the upgrade is successful,and the beeping sound stops after the VRX beeps for 5 seconds.

Software interface

Main interface-1

VTX input voltage
Detect VTX voltage, intelligently identify the voltage of 2, 3, 4, 6 string LiPo batteries, alarm when a single battery is lower than 3.5V, and alarm in red font when the voltage is too low.
VRX input voltage
Detect VRX low battery alarm, intelligently identify the voltage of 2, 3, 4, 6 string LiPo batteries, alarm when a single battery is lower than 3.5V, red font and buzzer alarm when the voltage is too loW.
Real-time bit rate
Display real-time transmission code rate, two display modes of 25.OMbps and 50.0Mbps.
Time delay
Displays the total delay from the transmission of images captured by the VTX camera to the ground end.
Ranging mode
The function of calculating the transmission distance from VRX to VTX according to the wireless transmission delay, the signal interferes will lead to error amplification.
Status prompt
The text prompts information that needs atterntion in the current state.
Current channel
Display the current setting channel, the signal grid has 5 states, 4 grids, 3 grids, 2 grids, 1 grid, and blank.
VRX SD card status
Display the status and remaining capacity of the VRX SD card. When recording, the red circle flashes to prompt, the status of the SD card not detected is displayed as NO SD, and the status of the memory is full is displayed as.
VTX storage status
Display the status and remaining capacity of the VTX storage, When recording, the red circle flashes to prompt, the status of the storage not detected is displayed as NO SD, and the status of the memory is full is displayed as.

Menu Channel-2

Display the interference situation of each channel. The signal strength is divided into 4 grids, 3 grids, 2 grids, 1 grid, and a space. The signal display space is OCCupied and cannot be selected. The white stroke is the selection box. Press the middlle button to confirm the current channel and highlight it.
Channel working logic: When switching between standard bit rate and high bit rate, the current channel will be set to CHP, and the channel needs to be reselected. CHP is a public channel, which is easy to be interfered and is not recommended for flight work; Auto is a channel that automatically refreshes the signal interference situation of all channels; Refresh is the channel of manual refresh.
Channel display of each country: FCC standard displays 8 channels (CH1/2/3/4/5/6/7/P), CE/SRRC standard displays 4 channels (CH1/2/3/P), MIC standard displays 3 channels (CH1/2/P). Only in FCC mode, the high bit rate mode can be turned on, and the 8 channels become 4 channels CH1, CH2, CH3, CHP.

Menu Settings-3

Transmit Power
The default transmit power can be 25mW, 200mW, 500mW, 700mW, the maximum can be set to 1200mW when FCC is turned on, and the maximum can be set to 350mW when MIC is turned on.
Resolution
The resolution can choose 720P and 1080P, when 1080P is selected, the high frame rate mode cannot be selected.
Bitrate
Standard bit rate and high bit rate can be selected to obtain different image quality, and high bit rate can only be enabled in FCC mode.
Frame Rate
Standard frame rate and high frame rate can be selected to obtain different time-lapse experiences, and high frame rate is only supported in 720P mode.
Standby Mode
When in standby mode, the transmission power of VTX terminal and VRX terminal is 10dbm, and the Current set transmission power will be output only after exiting standby mode or turning off the standby mode switch. Turning on the standby mode requires the air unit serial port to be correct connected to the flight controller. When the goggles receive the drone’s unlock signal, it will automatically exit the standby mode. If there is no flight Controller support, you can choose to turn off this function.
