Profile

A complete DJI LIGHTBIRDGE comprises of an air system and a ground system. It is a high definition video

transmitter, flight controller On Screen Display (OSD) and supports remote controls using the 2.4GHz

frequency band. As it is small, power efficient and highly sensitive, the DJI LIGHTBRIDGE can be used for

many activities. The air system must be attached to the aircraft and the ground system must be connected to a

monitor to display the video and flight controller OSD information.

When the DJI LIGHTBRIDGE transmits the video and flight controller OSD information, the air system is the

transmitter while the ground is the receiver. The air system pulls video from the camera and OSD information

from the flight controller then modulates it and transmits to the ground system. The ground system then

receives the information, demodulates it and sends it to a monitor or mobile device. The DJI LIGHTBRIDGE

App, available for smart devices is required for an ideal viewing experience.

When the DJI LIGHTBRIDGE transmits the remote control signal the ground system works as a transmitter

while the air system works as a receiver. The ground system can connect to two remote controls, one for

aircraft and the other for gimbal control. A DJI flight control system with DBUS port is required as the built in

receiver only supports the DJI DBUS protocol.

* 2.4GHz remote controls must be connected correctly to the ground system. Incorrect connection may lead to

malfunction due to interference.

Caution

Assembly Cautions

(1) Install antennas before powering on ground system or air system. (2) Point air system antennas downward when in use, do not twist or bend antennas. Avoid obstructing

antennas to ensure transmission quality.

(3) Keep both ends of air system antennas as further as possible to achieve optimal transmission

performance. In addition, keep these antennas away from metals.

(4) Use only DJI approved antennas and installed them correctly. Other antennas are incompatible. (5) Only 2.4GHz remote control can be connected to ground system of DJI LIGHTBRIDGE. Chose the

remote control with PPM trainer output.

(6) 2.4GHz remote controls must be connected to ground system for aircraft and gimbal control through

training ports. RF functions must be switched off.

(7) Do not create shorts or open circuits when soldering. (8) Do not rotate gimbal if connected to camera HDMI port using DJI AV gimbal. This will cause gimbal

or HDMI cable damage.

(9) Disconnect HDMI cable from the camera when powering on the DJI non-HD gimbal. Failure to do so

might damage HDMI cable.

(10) Keep HDMI cable away from on-board GPS module. (11) Do not modify DJI LIGHTBRIDGE.

Usage Cautions

(1) Check that all connections are correct and firm before every use. (2) Check ground system battery capacity before every use. If the battery capacity is lower than 25%,

charge ground system. If ground system powers off, the air system will enter failsafe mode.

(3) Check environment before every use to ensure no 2.4GHz device interference (e.g. other 2.4GHz

remote controls, Phantom 2 Visions).

(4) Check remote control channels using DJI LIGHTBRIDGE Assistant before every use to ensure a good

connection and normal functionality.

(5) The air system built-in receiver will go into failsafe mode if the remote control and ground system are

disconnected during use.

(6) Turn smart device sound volume to maximum to hear alarms more clearly, e.g. bad remote control

signal and low aircraft battery capacity.

Aircraft in flight can cause serious damage or injury. Please fly safely at all times.

(7) Flight control system OSD work best when more than 6 GPS satellites are searched. (8) Land slowly (≤1.5m/s) with the Phantom 2, as rapid landings can cause it to spin.

Others

(1) We strongly recommend using as many DJI parts as possible. (2) If you have problems you cannot resolve, please contact your dealer or DJI customer service.

This port be connected to the G7 port on a DJI HD gimbal or to other ports for the functions listed below: a) Power supply: (V+,V-) On-board battery (3S~6S) power connection. Non-DJI HD gimbal users must

use a seperate power cable or air system power CAN cable to connect air system and on-board

battery.

b) CAN-Bus: (L,H) OSD information from the flight system. For non-DJI HD gimbal users, connect to

the CAN-Bus port (for DJI A2 user, use the CAN 1 Bus port) on the flight control system with a

seperated CAN-Bus cable.

c) DVSB: (G-,+) DVSB video input from DJI HD gimbal.

2 Installation

Insert antennas into positions shown below. Ensure they click into place.

Notes

(1) Install antennas before powering on air system. (2) Point antennas downward when in use and avoid obstructions to ensure transmission quality. (3) Use only DJI antennas and install them correctly. Other antennas are incompatible. (4) Do not unplug the antennas unless it is absolutely necessary. Use tweezers to clamp on the metal part

of the antennas when unplugging the antennas. Do not apply excessive force on the antennas

otherwise it may cause damages to the antennas.

Attach two antennas to ground system according to example below. Screw them in tight.

Notes

(1) Attach antennas before powering on to avoid damage. (2) Use only DJI antennas and install them correctly. Other antennas are incompatible.

2.1 Air System Installation

2.1.1 Installing Antennas

2.2 Ground System Installation

2.2.1 Installing Antennas

Connect training port and Control In port on ground system using rectangle headed training port cable and

remote control cable. Supported remote controls include Futaba, Spektrum, Devention and JR. Refer to

remote control manuals for details.

Two remote controls can be connected to the ground system at once. See example below for details.

 Red jack connects to aircraft remote control.  Black jack connects to gimbal remote control.

Notes

(1) 2.4GHz remote controls must be connected to ground system for aircraft and gimbal control through

training ports, whose RF function should be switched off. Ground system will relay signals, remote

control will act as control system.

(2) 5.8GHz remote controls cannot be connected to ground system. Remote control signal is transmitted

by the remote control itself. Flight control system will communicate with receiver at 5.8GHz.

Additionally, DBUS on air system does not need connection.

2.2.2 Remote Control Connection

2.2.3 Remote Control Configuration

Remote control must be configured through Assistant for the flight control system before performing this step.

Pay special attention to the below:

1. Select AERO as TX model. Set all curves (pitch, throttle, expo, rates, etc.) to default. Set endpoints of all

channels to default (100%) and all trims and sub-trims to zero.

2. Check all channel outputs are “Basic” -> “RC” page.

1. Switch off RF. a) Press and hold “RTN” button to switch on remote control. b) Enter “POWER MODE” menu, select “RF OFF”.

POWER MODE RANGE CHECK

RF OFF

RF ON

c) RF indicator will turn off.

2. Set “TRAVEL” value of each channel within 100.

a) Double click “LINK” button to enter “LINKAGE” menu. Select “END POINT”. b) Enter “END POINT” menu, set “TRAVEL” value of each channel within 100.

END POINT 1/3 TRAVEL 1 AIL 135 100 100 135 2 ELE 135 100 100 135 3 THR 135 100 100 135 4RUD 135 100 100 135

Note

In some cases (namely Futaba T8J remote controls), actual “TRAVEL” value may exceed 100 even when

set to correctly. This inconsistency can be observed by viewing the “SERVO” in the “LINKAGE”, as

shown below. Actual GUI may vary between models.

Check that actual “TRAVEL” value does not exceed 100. If it does, reconfigure as necessary.

Refer to remote control manual for configuration. The below configuration process is based on a Futaba T8FG.
