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
