Before Use

1. Ensure that all connections are secure and there are no signs of malfunction.

2. Ensure that self-testing is completed successfully when the devices are turned on.

3. Ensure the surrounding area does not have other 2.4GHz transmitting devices that

may cause interference.

4. Ensure that the Ground System battery is above 25% to avoid losing control over the

Air System in mid-flight.

5. Switch your mobile device to Airplane Mode to avoid distractions from incoming calls

or messages.

6. Turn up your mobile device’s volume until you can hear warning alerts from the DJI

GO app clearly.

7. If the video breaks up, adjust the orientation of the Ground System antennas.

8. Ensure your onboard camera is fully charged.

DJI Lightbridge 2 is a long range video downlink capable of transmitting 1080p60 full HD video

at distances up to 1.2 miles (2 km). Lightbridge 2 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. Support for multiple Ground Systems allows one operator to control

aircraft movement, while the other operator focuses on video capturing. Real-time video and

ight telemetry can be viewed on your mobile device through the DJI GO app or live broadcast

to an SDI or HDMI display device.

Installation

Installing the Air System on Your Aircraft

1. Prepare the two Air System antennas and some double-sided foam tape.

2. Insert the antennas into the ports on the side of the Air System and snap into place.

3. Use the foam tape to mount the Air System onto the reserved space of your aircraft

or other suitable at surfaces.

Install the antennas before powering on the Air System.

For optimal transmission quality, point the antennas downwards and avoid

obstruction from other onboard equipment.

Only use ofcial DJI antennas and ensure they are installed correctly.

When connecting the antennas, ensure the connector pin is aligned with the port

hole, and DO NOT apply excessive force to avoid damaging the pin.

Only remove the antennas from the Air System unless it is absolutely necessary.

When removing the antennas, use pliers to grip the metal connector, and DO NOT

apply force to the wire.

For larger aircrafts, use an extension cable to connect the antennas to the Air

System. The DJI Spreading Wings series come with an antenna mount which is

used to position the antennas perpendicular to the landing gear. Watch the video

tutorials on the ofcial DJI website for more details.

Installation

Connecting the Ground System to Your Display Device

Select one of the video ports on the Ground System to output to your display device:

SDI – Connect your SDI monitor to the Ground System using an SDI cable.

HDMI – Connect your HDMI monitor to the Ground System using an HDMI cable.

DJI Lightbridge 2 User Manual

USB – Mount your mobile device onto the Mobile Device Holder and connect it to the Ground

System using a USB cable. Launch the DJI GO app to access video and ight telemetry.

The SDI or HDMI cable can be attached to the Ground System handle using the Wire

Clip (optional accessory).

The SDI and HDMI ports on the Ground System cannot be used together.

Below is an illustration using the USB video output. Please prepare a slotted screwdriver.

Install the Mobile Device Holder:

Installation

1. Unfold the Mobile Device Holder . Remove the screw using the slotted screwdriver .

2. Plug the Mobile Device Holder into the Ground System and tighten the Screw Lock.

3. Line up the hole on the Mobile Device Holder with the metal loop on the Ground System.

Insert and tighten the screw.

This section provides examples and way to congure Lightbridge 2. Choose the conguration

that best ts your needs.

Air System - DJI HD Gimbal + DJI Flight Controller

When used with a DJI HD gimbal, you can select either single or dual video source mode in the

DJI GO app. In single video source mode, the Air System transmits either the gimbal camera

video or FPV camera signal to the Ground System. In dual video source mode, both signals are

transmitted by the Air System.

Connect the system as follows:

1. Connect the gimbal port on the Air System to the G7 port on the DJI HD gimbal and the CAN

BUS port on the ight controller.

2. Connect the HDMI or AV port on the Air System to the FPV camera.

3. Connect the DBUS port on the Air System to the DBUS port (X2 port) on the ight controller with

the DBUS cable.

4. Refer to the user manuals for the gimbal and ight controller for details.

Only use the DJI HD gimbal and DJI ight controller with the latest rmware.

If you are using the DJI A2 Flight Controller, connect the gimbal cable to the CAN 2

port on the controller unit.

Installation

A CAN-HUB is recommended to provide extra CAN ports, if there is not enough CAN port.

Ground System - Dual Ground Systems Mode

More than one Ground System can connect to the same aircraft in Dual Ground System Mode.

In Dual Ground System Mode, the Master Ground System controls the movement of the aircraft,

while the Slave Ground System controls the movement of the gimbal and camera. When

multiple Slave Ground Systems (max of 3) are connected to the aircraft, only the rst connected

Slave Ground System is able to control the gimbal. The remaining slave Ground System can

view the live feed video from the aircraft, but they cannot control the gimbal.

Ground System

The Ground System features a number of standard interfaces intended for aircraft and camera

control, which are explained below with their most typical functions. However, you can remap

these interfaces to the ight controller channels using the DJI Flight Controller Assistant.

Compliance: The Ground System is compliant with both CE and FCC regulations.

Control Stick Modes: Mode 1, Mode 2, or a customized mode.

Mode 1: The right stick serves as the throttle.

Mode 2: The left stick serves as the throttle.

DO NOT operate more than 3 aircrafts within in the same area (size equivalent to a

soccer eld) to prevent signal interference.

Ground System Operations

Using the Power Button

1. Press the power button once to display the current battery level.

2. Press again and hold to power on the Ground System.

3. The Status Indicator will blink green (blink purple for Slave Ground Systems) rapidly when

the Ground System is linking to the Air System, and become solid green when the link is

established.

4. Press the power button once, again, and hold to power off the Ground System.

P-Mode (Positioning):

The aircraft uses GPS for positioning. This mode works best when the

GPS signal is strong.

A-Mode (Attitude):

GPS is not used for positioning, and the aircraft only uses its barometer to

maintain altitude. If a GPS signal is present, the aircraft will still return to the last recorded Home

Point if the Ground System signal is lost.

F-Mode (Function):

Acts as A-Mode (default) or Manual Mode for Lightbridge 2. Select the

desired mode in the DJI Flight Controller Assistant.

Return-to-Home (RTH)

Press and hold the RTH Button to bring the aircraft back to the last recorded Home Point.

The LED around the RTH Button will blink white during the RTH procedure. Refer to the ight

controller user manual for more information on how to regain control during RTH.

The DJI WooKong-M Flight Controller does not support the RTH feature.

Optimal Transmission Range

To achieve optimal transmission, separate the two antennas and adjust their positions so that

the at side faces the aircraft.

Optimal Transmission RangeStrong Weak

If the transmission signal is weak, adjust the positions of the antennas and fly the aircraft

closer to you.
