3. Installation
3.1.Air Unit Installation
3.1.1. Antenna installation
Insert the air unit antennas into the RF ports. Antenna clicks in when properly installed.
9
3.1.2. Power supply
Pin-out: - - + +. Insert the four-pin connector of supplied power cable to the power port
of the air unit and connect the orange power connect of supplied power cable to a battery
output, or the power supply port of a drone. Recommended voltage is 12V.
Note:
(1) To avoid equipment damage, install antennas before powering on the units.
(2) Recommended rated voltage/current is DC12V/1.2A (or 3S lithium battery).
3.1.3. Connection to camera
Connect the HDMI video output port to the HDMI video input port of the air unit.
10
3.1.4. Connection to flight controller (RC & telemetry)
Insert the six-pin connector of supplied serial cable to the serial port of the air unit and
connect the other end of the serial cable to the telemetry port of a flight controller.
Insert the supplied RC cable to the RC port of the air unit and connect the other end of the
RC cable to the PPM/S.BUS port of a flight controller.

3.2.Ground Unit Installation
3.2.1. Antenna installation
Screw the ground unit antennas onto the RF ports. Make sure the antennas are tightly
installed.
Note:
(1) To avoid equipment damage, install antennas before powering on the units.
(2) Ensure the antenna connector is vertical to the module when it is screwed onto the RF
port. Screw the antenna tightly to avoid loose connection, but do not overtighten the
antenna to avoid damaging the antenna.
(3) Both antennas need to be installed.
(4) Adjust the antenna to be vertical to the ground during operation.
