Warning
1. Installation
•
Always connect the Air System antenna extension
cables before connecting the Air System antennas.
DJI takes no responsibility if the transmission power
exceeds the legally regulated amount because of
failure to use the antenna extension cables.
•
Only use ofcial DJI accessories.
•
Install the Air System antennas before powering on Datalink 3.
•
To attain optimal signal transmission, point the Air System antennas downwards and avoid
obstruction from other onboard equipment. DO NOT twist or bend the Air System antennas.
•
Keep the Air System antennas as far apart as possible and away from metal objects to attain
optimal transmission.
•
Only use ofcial DJI antennas for the Air System and Ground System.
•
Maintain an appropriate distance between electronic components to reduce electromagnetic
interference as much as possible.
2. Before Use
•
The Air System power cable (black-red-black) is for power only. Be sure to insert it into the
power port of the Air System. Inserting it into incorrect ports will lead to permanent damage.
•
Make sure you fully charge the Ground System before each ight.
•
If the Ground System is powered on and is NOT used for more than ve minutes, it will sound
an alert. After six minutes, it will automatically power off. Move the sticks or perform some other
action to cancel the alert.
•
Adjust the clamp of the mobile device holder to allow for a rm grip on your mobile device.
•
Ensure the mobile device holder is rmly in place and does not slip.
•
Ensure the antennas of the Ground System are unfolded and adjusted to the proper position to
achieve optimal transmission quality.
•
Repair or replace the Ground System if it is damaged. A damaged Ground System antenna will
greatly decrease performance.
•
Recharge the battery at least once every three months to prevent over-discharging. The battery
will enter hibernation mode if depleted and stored for an extended period of time.
Always stay alert when using
Datalink 3. Carelessness
may result in serious harm
to yourself or others.

Introduction
DJI Datalink 3 is a long range downlink system capable of transmitting data at distances of up to
2.49 mi (4 km) *. It is compatible with DJI ight controllers ** and other non-DJI ight controllers
with SBUS protocol ***. Datalink 3 includes a Ground System and an Air System, which can be
operated at a 2.4 GHz frequency. The multi-functional ports on the Air System can satisfy user
requirements in a variety of applications ***. Datalink 3 integrates the remote controller module
into the Ground System, which comes with a number of aircraft and gimbal controls, as well as
some customizable buttons. By using channel settings, i.e. DJI ASSISTANT™ 2 for DJI series
flight controllers, the buttons on the remote controller can be customized to perform common
functions used in photography, mapping, and agriculture, etc. When used with either DJI MG or
GS Pro apps, users will be able to see and adjust settings in real time, completing complex tasks
more easily. The remote controller has a maximum working time of 15 hours.

When using the DBUS cable to connect the flight controller and the Air System, no extra
power supply is needed. DO NOT use the power port on the Air System for power supply. It
is, however, essential to provide an additional power supply (8~30 V) when using the SBUS
cable to connect the ight controller and the Air System.

* Please refer to “Specications” for more detailed information on supported DJI ight controllers.
** The remote controller can reach its maximum transmission distance (FCC) in wide open areas with no electro-magnetic
interference, and at an altitude of around 100 meters.
*** The CAN port on the Air System is currently only compatible with ofcial DJI equipment. The UART port is currently not
supported but will be added in a future rmware update. Please visit the ofcial website for all the latest information.

Installing the Air System
The antennas need to be mounted on the Air System to communicate with the Ground System.
When using Datalink 3, please make sure you connect the Air System antenna extension cables,
then the Air System antennas.
1. Prepare the two antenna extension cables, two Air System antennas, and some double-sided
foam tape.
2. Insert the Air System antenna extension cables into the ports on the side of the Air System, and
snap them into place.
3. Connect the Air System antennas to the antenna extension cables.
4. Use the foam tape to mount the Air System onto the reserved space of the aircraft or other
suitable at surfaces.
Install the antennas before powering on the Air System.
For optimal transmission quality, point the antennas downwards and avoid obstruction from
other onboard equipment.
Only use ofcial DJI antennas and make sure you install them correctly.
When connecting the antennas, ensure the connector pin aligns with the port hole. DO NOT
apply excessive force to avoid damaging the pin.
DO NOT remove the antennas from the Air System unless necessary. When removing the
antennas, use pliers to grip the metal connector. DO NOT apply excessive force to the wire.
