About
Working in 2.4GHzfrequency band, anair unit and a ground unit compose the LIGHTBRIDGE, which
transmits video image, flight controller OSD and transmitter control signal. Having the characteristics of
small dimension, low power consumption and high sensitivity, the LIGHTBRIDGE can be widely applied
various fields for wireless communication. For aeromodelling activity, attach theair unit to the aircraft and
connect the ground unit to a monitor for displaying the video image, flight controller OSD information.
When the LIGHTBRIDGE transmitsthe video image and flight controller OSD information, the air unit is
working as transmitting equipment and the ground unit as receiving equipment. The air unit gets the video
image from a camera and OSD information from the flight controller, modulates and wirelessly transmits it to
the ground unit. Theground unit receives the information, demodulates and sends it to display on a monitor
or a smart phone. To obtain a better experience, download the DJI LIGHTBRIDGE App via a smart phone for
displaying the video image and flight controller OSD information.
When the LIGHTBRIDGE transmitsthe transmitter control signal, the ground unit is working as transmitting
equipment connecting with transmitter and the air unitas receiving equipment built in a receiver.The ground
unit can connect to two transmitters for both aircraft and gimbal control. It should be used with the DJI flight
control system via the DBUS port connection since the built-in receiver can only support DJI DBUS protocol.
* For the 2.4GHz transmitter, it should be correctly connected to the ground unit, otherwise may lead to
malfunction due to interference.
