Disclaimer Thank you for purchasing the DJI LIGHTBRIDGE. Please visit the DJI LIGHTBRIDGE page on www.dji.com regularly to keep up with product information, technical updates and manual corrections. Information in this manual is subject to change without notice in line with product upgrades and updates. Users must comply with local radio transmission laws and regulations when using this product.
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.
Caution Aircraft in flight can cause serious damage or injury. Please fly safely 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. 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.
(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. ©2014 DJI. All Rights Reserved.

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.
2.2.2 Remote Control Connection 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.
2. Check all channel outputs are “Basic” -> “RC” page. Refer to remote control manual for configuration. The below configuration process is based on a Futaba T8FG. 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) 2. RF indicator will turn off. Set “TRAVEL” value of each channel within 100. a) Double click “LINK” button to enter “LINKAGE” menu. Select “END POINT”.
2.2.4 Video Output Connection HDMI and USB ports output video, however the output options are mutually exclusive. Select either HDMI or USB output base on your choice of device.

The below example uses the USB port connection. Note Do not attach HDMI and USB devices to the ground system simultaneously.
hand, the air system simultaneously relays gimbal camera and FPV camera video signal to the ground system. The ground system can one of the video signal from the air system. Note that video output source is defaulted to “HDMI/AV”, user should manually select “HD gimbal” when they are connecting DJI HD gimbal to the air system. Scenario 1 – Dual Video Source with Dual Remote Control Use two remote controls to control gimbal and aircraft independently.
FPV Camera Gimbal Camera FPV Camera Video Scenario 2 - Dual Video Source with Single Remote Control Use single remote control to control gimbal and aircraft independently. Map the gimbal and aircraft control channels to the remote control through DJI LIGHTBRIDGE Assistant. In single video source mode, aircraft operator receives the FPV camera video feed from the master ground station, while the gimbal operator receives DJI HD gimbal video feed from the slave ground station. Air system connection： 1.
2. Connect HDMI /AV port to the FPV camera. 3. Connect DBUS port on air system to DBUS port (X2 port) on flight control system with DBUS cable. 4. Refer to gimbal and flight control system manuals to complete connection. Ground system connection： 5. Connect remote control to the ground station via training port. 6. Connect mobile devices or HDMI monitor to the master and slave ground station. 7. Launch DJI LIGHTBRIDGE App and configure the Master –Slave mode in “App Settings”.
Scenario 3 - Single Video Source with Dual Remote Control Use two remote controls to control gimbal and aircraft independently. Map the gimbal and aircraft control channels to both of the remote controls through DJI LIGHTBRIDGE Assistant. In single video source mode, the aircraft operator and gimbal operator use different remote control to reduce interferences. Air system connection： 1. Connect Gimbal Port on air system to G7 port on DJI HD gimbal with supplied Gimbal cable (DJI HD gimbal). 2.
Scenario 4 – Single Video with Single Remote Control Use two single controls to control both gimbal and aircraft. Map the gimbal and aircraft control channels to a single remote controls through DJI LIGHTBRIDGE Assistant. Air system connection： 1. Connect Gimbal Port on air system to G7 port on DJI HD gimbal with supplied Gimbal cable (DJI HD gimbal). 2. Connect DBUS port on air system to DBUS port (X2 port) on flight control system with DBUS cable. 3.
the air system. When using camera that has HDMI output, connect HDMI output from the camera to the HDMI input port on the air system. It is possible to control air craft and gimbal using single remote control, as long as proper channel mapping is completed in DJI LIGHTBRIDGE Assistant. It is also possible to control the gimbal independently with a 5.8GHz receiver, in this scenario, it is required to connect the 5.8GHz receiver to the AUX2 port on the DJI gimbal. Scenario 5 – DJI non-HD gimbal with 5.
connections: 1. Connect either HDMI or AV port on the air system to the HDMI or AV port according to the choice of the camera. 2.

2.3.4 Phantom 2 Vision+ Mode Scenario 9 – Phantom 2 Vision+ with DJI Lightbridge To use Phantom 2 Vision+ with DJI Lightbridge, visit DJI WIKI page on DJI official website (http://wiki.dji.com/en/index.php/Using_a_DJI_Phantom_2_Vision%2B_with_the_DJI_Lightbridge) for details. 2.3.5 DIY Mode Only HDMI and AV port is available for video transmission under DIY mode. Scenario 10 – DIY mode DIY users should select either HDMI or AV based on camera video output and follow the below connection procedures: 1.
3 Using DJI LIGHTBRIDGE 3.1 Master-Slave Mode This is a one-to-multi transmission mode. Linked air and ground systems act as a broadcast master pair. Dual link transmission is carried out between the master pair. The master ground system receives video and relays remote control signals to the air system. Ground systems that have not been linked to the air system are slaves. Slaves can only receive video from the air system. The example below uses a DJI HD gimbal.
