1. Mount the Rover Unit securely to the drone.(Choose best install position according to cable length)
2. Choose the best position to attach the rover unit antennas. Airunit antenna should no attached to metal parts or any conductor，which will affect the signal transmit distance. The antenna should be installed vertically and keep an Angle of about 15 degrees to obtain better gain.
Please refer to Figure 1 and Figure 2 below. (Note that carbon fiber is also conductive material.)
3. Connect S.bus on Airunit to the RCIN on the Flight Controller.
4. Connect UART on the Airunit to the TELEM 1 or TELEM 2 on the Flight Controller.
5. Connect 5V - 12.6V max (3s Lipo supported) battery to the power input on the Rover Unit.
6. Connect camera to HDMI 1 (preferred) on the Airunit. If you are using two video stream,please connect the second camera to HDMI 2. You may switch from Stream 1 and Stream 2 on controller to display the corresponding video stream.
1. Use M1.6x3mm screw to mount Airunit on back board.
