Profile A complete Lightbridge 2 comprises of an air system and a Ground S ystem. It is a high definition video transmitter, and supports Ground System using the 2.4GHz frequency band. As it is small, power efficient and highly sensitive, the Lightbridge 2 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 information, you can also control your aircraft and gimbal with the Ground System. When the Lightbridge 2 transmits the video and flight controller information, the air system is the transmitter while the ground is the receiver. The air system pulls video from the camera and flight controller information then modulates it and transmits to th e Ground System. Th e Ground System then receives the information, demodulates it and sends it to a monitor or mobile device. The DJI GO app, available for mobile devices is required for an ideal viewing experience.
When the Lightbridge 2 transmits the G round S ystem signal, the Ground System works as a transmitter while the air system works as a receiver. The Ground System supports Dual Ground System mode. In Du al Con tro llers mod e, th e “M ast er ” Ground System operator controls the orientation of the aircraft, while the “Slave” Ground System controls the movement of the gimbal and camera operation. A DJI flight control system with DBUS port is required as the built in receiver only supports the DJI DBUS protocol. The Ground System includes Remote Controller module, th e reserved buttons on the Ground System c an be customized set by the flight controller’s assistant for expansion use.

2.3.1 Air System DJI HD Gimbal + DJI Flight Controller When using with DJI HD gimbal, you can select either single or dual video source. By single video source mode, it means the air system relays either the gimbal camera video or the FPV camera video signal to the Ground System. These two video sources are mu tually exclusive under single video source mode. On the other hand, the air system simultaneously relays gimbal camera and FPV camera video signal to the Ground System. Note that user should manually select “HD gimbal” in vid eo output source when they are connecting DJI HD gimbal to the air system. The connection steps are as follows: 1. Connect Gimbal Port on the air system with supplied Gimbal cable，then connect it to G7 port on DJI HD gimbal and CAN 2 Bus port on the flight controller. 2. Connect HDMI /AV port on the air system to the FPV camera. 3. Connect DBUS port on air system to DBUS port (X2 port) on flight controller with DBUS cable. 4. Refer to gimbal and flight controller manuals to complete connection. The connection figure below take DJI HD gimbal and A2 fight controller as example: FPV camera is not needed in single video source mode.
2.3.2 Ground System Dual Ground Systems Mode More than one Ground System can connect to the same aircraft in Dual Ground System mode. In Dual Controllers mode, the Master Ground S ystem c ont ro ls th e 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 connect to th e airc raft, only the first connected Slave Ground System is able to control the gimbal, the remaining slave Ground System can view the live feed video f ro m th e aircraft, but they cannot control the gimbal.
Use th e gimbal dial on the Ground System to control the pitch movement of the camera in the single Ground System mode, however, you cannot pan the camera.
