# 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 control s 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 recei v er
. T he air system pulls video from the camera and OSD information from the flight controller then modulate s it and transmits to the ground system. The ground system then
receives the information, demodulate s 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 work s as a transmitter while the air system works as a receiver. T he ground s ystem can connect to two remote control s, 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 support s the DJI DBUS protocol

.

* 2.4GH z remote control s must be connected cor rectly to the ground system . Incorrect connection may lead to
malfunction due to interference

# Caution Aircraft in flight can cause serious damage or injury. Please fly safe ly at all times. 

## 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

. A void obstructing

antennas to ensure transmission quality. (3) Keep both ends of air system antennas as further as possible to achieve optimal transmi ssion performance. In addition, keep these antennas away from metals. (4) Use only DJI approved antennas and install ed them correctly. O ther 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 control s must be connected to ground system for aircraft and gimbal control through training ports

. RF function s must be switched off. (7) Do not create short s or open circuit s when soldering. (8) Do not rot ate gimbal if connect ed to camera HDMI port using DJI AV gimbal. T his 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 us e
. (2) Check ground system battery capacity before every us e
. I f the battery capacity is lower than 25%, charge ground system . If ground system power s off , the air system will enter failsafe mode

. (3) Check environment before every us e to ensure no 2.4GHz device interf erence (e.g. other 2.4GHz
remote control s , Phantom 2 Vision s ). (4) Check remote control channels using DJI LIGHTBRIDGE Assistant before every us e to ensure a good
connection and n ormal functionality

. (5) The air system built

- in receiver will go into failsafe mode if the remote control and ground system are disconnected during us e
. (6) Turn smart device sound volume to maximum to hear alarms more clearly, e.g. bad remote control signal and low aircraft battery capacity.©201 4 DJI. All Rights Reserved. 5

(7) Flight control system OSD work best when more than 6 GPS satellit es are searched. (8) L and 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 problem s you cannot resolve, please contact your dealer or DJI customer service.©201 4 DJI. All Rights Reserved. 6

### 2.2.2 R emote Control Connection Connect training port and C ontrol I n port on ground system using r ectangle headed training port cable and

remote cont rol cable . Supported remote control s include Futaba, Spektrum, Devention and JR. Refer to
remote control manuals for details.
Two remote control s can be connected to the ground system at once. See example below for details.

 R e d jack connects to aircraft remote control.

 Black jack connects to gimbal remote control.



### Notes (1) 2.4GHz remote control s 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 si gnals, remote
control will act as control system. (2) 5.8GHz remote control s can not be connect ed 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.



### 2.2.3 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. S elect AERO as TX model. Set al l curves (pitch, throttle, expo, rates, etc.) to default. Set endpoints of all channels to default (100%) and all trims and sub

- trims to zero.©201 4 DJI. All Rights Reserved. 15

2. Check all channel output s are “ Basic ”

- > “ RC ” page. Refer to remote control manual for configuration . The below c onfiguration process is based on a Futaba T8FG.
1. Switch off RF. a) Press and hold “ RT N ” 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 control s), actual “ TRAVEL ” value may exceed 100 even when set to correctly. This inconsistency can be observed by viewing the “ SE RVO ” in the “ L INKAGE ” , as shown below. Actual GUI may var y between models.

C heck that actual “ TRAVEL ” value does not exceed 100. If it does, reconfigure as necessary.©201 4 DJI. All Rights Reserved. 16
