Digital Video Transmission
In addition to install the Pagoda antenna
(SMA interface) to the SMA Port of the
DJI Goggles RE, you will also need to
install the DJI OcuSync Air System on a
third-party racing drone to work with the
goggles. Refer to the illustration below to
mount and connect the modules onto your
aircraft.
DJI OcuSync Camera
3-in-1 Cable (Power, S.Bus, UART)
RED: Power (9-16.8 V)
BLACK: Power GND
BROWN: Signal GND
The S.Bus Port and the PPM Port on the Air Unit are only used when transmitting the remote control signal.
These ports don't need to be connected if video downlink is used only.
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 select the transmission channel manually to avoid interference from
other devices.
Please be aware that the Air Unit may become very hot during, or after operation. DO NOT touch it before it
has cooled down sufficiently.
Please avoid using the Air Unit for an extended time when there is no external cooling equipment.
Otherwise, it might get overheated and enter into 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 type of conductor. Also, make sure to keep
the bottom of the antenna at least 25 mm away from potential conductors like cables, carbon fiber frames,
batteries, and metals, etc.
If you are only using the Air Unit to transmit the downstream video signal, DO NOT use the same frequency
band as the upstream control signal to avoid interference.

Pagoda Antenna
Cylindrical Antenna
Dipole Antenna
After familiarizing yourself with the digital video transmission, you can connect the trainer
port of a third-party remote controller and the audio port on the DJI Goggles RE through
the trainer cable to transmit the control signal to the racing drone.

Devices that support PPM
signals (e.g. actuator)
WHITE: UART RX (Connects to OSD TX, 0-3.3 V)
GRAY: UART TX (Connects to OSD RX, 0-3.3 V)
YELLOW: S.Bus (Connects to Flight Controller RX, 0-3.3 V)
Description
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.
Dual-frequency circular polarization omnidirectional, providing a
smooth video transmission experience.
Dual-frequency linear polarization omnidirectional, suitable for
close-up flight.
RED: Power (5 V)
BLACK: Signal GND
PPM Cable
WHITE: PPM signal (0-5 V)
