User Manual
The S.Bus port and PPM port on the Air Unit are only used when transmitting remote
control signals. These ports don’t need to be connected if only using video downlink.
There are up to 19 channels (5.8 GHz: 12 channels; 2.4 GHz: 7 channels) for digital video
transmission, and each bandwidth is 10 MHz. You can manually select the transmission
channel to avoid interference from other devices.
Please be aware that the Air Unit may become very hot during or after operation. DO NOT
touch the Air Unit before it has sufciently cooled down.
Please avoid using the Air Unit for an extended period of time when there is no external
cooling equipment present, as this may cause the Air unit to enter Overheat Protection
mode. Wait for the module to cool down and then you can restart it. It is recommended to
have an external fan installed to dissipate heat.
Place the two antennas on the Air Unit vertically and parallel to each other at least 30 mm
apart. Please note that you should avoid placing the antennas level with any electrically
conducive material. Also, make sure to keep the bottom of the antenna at least 25 mm
away from potential conductors such as cables, carbon fiber frames, batteries, and
metals.
If you are only using the Air Unit to transmit downstream video signals, DO NOT use the
same frequency band as the upstream control signal to avoid interference.
Antenna Description
Pagoda Antenna
5.8 GHz single frequency circular polarization omnidirectional, small
size, recommended for racing. Do not use this antenna when using the
2.4 GHz frequency band.
Cylindrical Antenna
Dual-frequency circular polarization omnidirectional, providing smooth
long-range video transmission.
Dipole Antenna
Dual-frequency linear polarization omnidirectional, suitable for close-up
ight.
3. Power on the DJI OcuSync Air Unit and press the link button on the Air Unit with an appropriate
tool when the linking status indicator is solid green. The indicator will turn solid red when the air
unit is waiting for linking.
4. Power on the Goggles RE, then press the link button with an appropriate tool in the main menu,
or just swipe down on the touch panel with two ngers to enter the shortcut menu and select
“Racing Drone (Digital) > Linking Settings > Quick Linking”.
5. Make sure the distance between Goggles RE and the Air Unit is within 2 m. Both linking status
indicators will turn solid green when successfully linked, and the video will display normally.
Multi-Device Linking
The DJI OcuSync Air System supports linking two devices to receive video transmission at the same
time. Below are two specic scenarios.
Two Goggles RE:
1. Follow the steps 1 and 2 of “Basic Linking” above to complete the linking of Goggles RE and DJI
OcuSync Air System respectively.
