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

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.
Installation
3. Use the foam tape to mount the Air System onto the reserved space of your aircraft
or other suitable flat 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 official 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 official DJI website for more details.
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.

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 flight 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.

Standard Configurations
This section provides examples and way to configure Lightbridge 2. Choose the configuration
that best fits 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.
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 flight 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 flight controller with
the DBUS cable.
4.Refer to the user manuals for the gimbal and flight controller for details.
Only use the DJI HD gimbal and DJI flight controller with the latest firmware.
If you are using the DJI A2 Flight Controller, connect the gimbal cable to the CAN 2
port on the controller unit.
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 first 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 flight 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 field) to prevent signal interference.
