Antenna Installation **

**

Please use a 5.8 GHz antenna for video transmission , and the interface is U. FL .

Notice:

1. When using a feeder connection, it may have an impact on RF performance (power or  signal quality ) , please choose an appropriate feeder.

power supply

The power supply range of AU is power supply voltage is 12V .video transmission power is set to  10dBm . When both walking the typical power consumption is 12V@0.64A, mavlink and sbus are  working, the typical power consumption is 12V@0.64A . There may be a difference of about ±  0.2 A between different devices or different channels .

NOTE: Please make sure the antenna is installed correctly before plugging in the power  source.

video source

AU supports Micro HDMI interface to input video sources.

AU supports the following resolution input:

• 720P60
• 720P50
• 720P30
• 1080P30
• 1080P60

AU will downsample the image before RF transmission based on the video resolution and current  channel bandwidth, please refer to Table 2-2 . Downsampling does not affect the output  resolution of the GS side.

Table 2-2

Note: When no HDMI video source is detected, AU will automatically output a blue screen with a resolution of 1 080 P 30 .

Video transmission

AU video transmission supports a total of 15 channels, of which 5 HD channels have a bandwidth  of 20 MHz, and 10 SD channels have a bandwidth of 10 MHz . Please see Table 2-1 for the specific  center frequency points .

Users can switch in the following three ways:

Button : Each time the button is pressed briefly, the channel increases by 1.

• When the channel is HD 5 , short press the button to switch to SD 1 channel;
• When the channel is SD 10 , short pressing the button will switch to HD 1 .

Futaba Configurator : via micro Connect the AU to the F utaba Con figurator software on the  PC with a usb cable , select the target channel in the settings menu and save it.  Host Command: Please refer to Futaba command related documents.

data transmission

The number of AUs transmitted is 23 dBm, which cannot be set by the user.(US) module FCC ID:  NS913P900

pair

AU should be paired with GS before it can be used normally . Otherwise, communication will be  impossible even if the channels match each other. AU and GS only need to be paired once to  confirm each other’s identities, and there is no need to pair again after powering on again.  Pairing process:

• The user controls AU and GS to enter pairing mode respectively.
• PAIR between AU and GS The LED starts to flash and the GS screen displays PAIRING G.  – Waiting for AU to pair with GS.
• The GS displays the AU screen and the PAIR LED of the GS no longer flashes, indicating that  the GS pairing is completed.
• The AU’s PAIR LED no longer flashes, and the AU pairing is completed.

AU can pass Futaba Host command or press and hold the button for 5 seconds to enter pairing  mode.

Note: Before pairing, the AU and GS do not need to be on the same channel. The GS will  automatically adapt to the AU’s channel during pairing.

SBUS

AU supports SBUS signal output to the flight controller, and the SBUS output period is 15ms .

Notice:

1. When the AU receives the SBUS data from the GS, the SBUS starts outputting data.
2. AU When GS data cannot be received after SBUS starts output, AU will keep the last received  data for output.
3. The SBUS interface has a power line for providing 5.5 V voltage, but it is not available by  default at the factory.

MAVLINK **

**

AU supports transmitting flight control mavlink data to the ground station. The baud rate is 1  15200 , please connect the mavlink interface to the flight controller.

Firmware update **

**

• Use Micro Connect the AU to the PC (windows) side with a USB cable .
• Open Futaba on PC Configurator software.
• Select the corresponding serial port in the software and open it.
• Update DM5680 , STM32 , and fpga respectively in the firmware .
• RemoveMicro USBRemove the USB cable and power cycle. update completed.
