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.

Connection
Air unit Connection
Install Antennas
Insert the antennas to the position shown in the illustration below. Ensure that you heard a ‘click’ sound
to confirm the antennas are in place.
Notice
(1)
Install the antennas before the air unit is powered on.
(2)
When in using, placed the antennas downward and keep it unobstructed to ensure the
transmission signal quality.
(3)
Ensure to use the special antennas and install them by a professional trained. Any other types of
antennas are forbidden.
Video Source Connection
Connection
DJI Lightbridge supports both the HDMI and AV input. Refer to the illustration below for
connection.For HDMI input, connect the HDMI cable to the HDMI port on the camera.For AV input,
connect the AV cable to the AV output port on the camera. When using the DJI gimbal, connect to
the video output port on the GCU model. The illustration below use the DJI GCU as the example.
12
Connect to Flight Control System
Currently the only flight system control that Lightbridge supported is DJI A2, refer to the user manual of
DJI A2 to complete the following connection:。
1.
Connect the DBUS cable to the DBUS port (X2 port) on the DJI A2 flight control system.
2.
GIMBAL PORT provides three functions, they are CAN-Bus, power supply and DVSB connection.
The DVSB port is a reserved port that should not be connected. For the air unit connection, connect
the CAN-Bus port to the CAN-bus port, and connect the other end to CAN 1 port on the flight
control. Select an appropriate power plug to connect the battery.

Caution
(1)
Be sure to attach the antennas before power on the ground unit, otherwise it may cause damages
to the device.
(2)
Ensure to use the special antennas and install them by a professional trained. Any other types of
antennas are forbidden.
Remote Controller Connection
Connect the training port and the CONTROL IN port on the ground unit by using the training port output
cable and remote control connection cable. The supported remote control includes: Futaba, Spektrum,
Devention and JR remote controller. Refer to the corresponding remote controller manuals for detailed
usage.
Two remote controllers can be connected to the ground unit at the same time, followthe illustration
below for the connection:
Red jack connects to the remote controller for the aircraft.
Black jack connects to the remote controller for the gimbal.

Transmitter Configuration
Refer to your own remote controller for reference. The below configuration process is based on Futaba
T8FG as the example:
1.
Switch off the RF option. The below procedure takes the Futaba T8FG as the example:
a)
Press and hold the [RTC] button to switch on the remote controller.
b)
Enter [POWR MODE] menu, select [RF OFF].

Set the [TRAVEL]value of each channels at the range within 100. The below procedure takes the
Futaba T8FG as example:
a)
Double click the [LINK] button to enter [LINKAGE MENU], select [END POINT] option.
b)
Enter [END POINT] menu, set the [TRAVEL] value of each channels at the range with 100 as

Notice
(1)
Position the air unit antennas downward and the ground unit antennas upward and ensure there is
no obstacle between the air unit antennas and ground unit antenna otherwise the transmission
distance may be affected.
(2)
When the air unit is receiving signals, both the antennas stop transmitting signals, one of the
antenna starts receiving signals. Both antennas resume transmitting signals when the receiving

operation is completed.
(3)
When the ground unit is receiving signals, both the antennas stop transmitting signals and start
receiving signals. When the ground unit is transmitting signals, the antennas stop receiving signals
and one of the antennas starts transmitting signals.
