About Working in 2.4GHzfrequency band, anair unit and a ground unit compose the LIGHTBRIDGE, which transmits video image, flight controller OSD and transmitter control signal. Having the characteristics of small dimension, low power consumption and high sensitivity, the LIGHTBRIDGE can be widely applied various fields for wireless communication. For aeromodelling activity, attach theair unit to the aircraft and connect the ground unit to a monitor for displaying the video image, flight controller OSD information. When the LIGHTBRIDGE transmitsthe video image and flight controller OSD information, the air unit is working as transmitting equipment and the ground unit as receiving equipment. The air unit gets the video image from a camera and OSD information from the flight controller, modulates and wirelessly transmits it to the ground unit. Theground unit receives the information, demodulates and sends it to display on a monitor or a smart phone. To obtain a better experience, download the DJI LIGHTBRIDGE App via a smart phone for displaying the video image and flight controller OSD information. When the LIGHTBRIDGE transmitsthe transmitter control signal, the ground unit is working as transmitting equipment connecting with transmitter and the air unitas receiving equipment built in a receiver.The ground unit can connect to two transmitters for both aircraft and gimbal control. It should be used with the DJI flight control system via the DBUS port connection since the built-in receiver can only support DJI DBUS protocol. * For the 2.4GHz transmitter, it should be correctly connected to the ground unit, otherwise may lead to malfunction due to interference. 2

Connection Air unit Connection Install Antennas Insert the antennas to the position shown in the illustration below. Ensure that you heard a ‘click’ sound to confirm the antennas are in place. Notice (1) Install the antennas before the air unit is powered on. (2) When in using, placed the antennas downward and keep it unobstructed to ensure the transmission signal quality. (3) Ensure to use the special antennas and install them by a professional trained. Any other types of antennas are forbidden. Video Source Connection Connection DJI Lightbridge supports both the HDMI and AV input. Refer to the illustration below for connection.For HDMI input, connect the HDMI cable to the HDMI port on the camera.For AV input, connect the AV cable to the AV output port on the camera. When using the DJI gimbal, connect to the video output port on the GCU model. The illustration below use the DJI GCU as the example. 12

Connect to Flight Control System Currently the only flight system control that Lightbridge supported is DJI A2, refer to the user manual of DJI A2 to complete the following connection:, 1. Connect the DBUS cable to the DBUS port (X2 port) on the DJI A2 flight control system. 2. GIMBAL PORT provides three functions, they are CAN—Bus, power supply and DVSB connection. The DVSB port is a reserved port that should not be connected. For the air unit connection, connect the CAN—Bus port to the CAN—bus port, and connect the other end to CAN 1 port on the flight control. Select an appropriate power plug to connect the battery. § * 4 Battery C Reserved CAN1Bus c Caution Connect the air unit to one of the CAN—Bus port that attached to the CAN 1 bus. Do not connect the air unit to the CAN 2 port. Ground Unit Connection Install Antennas Attach two antennas to the ground unit according to the illustration shown below. Screw tight the antennas. 13

Caution (1) Be sure to attach the antennas before power on the ground unit, otherwise it may cause damages to the device. (2) Ensure to use the special antennas and install them by a professional trained. Any other types of antennas are forbidden. Remote Controller Connection Connect the training port and the CONTROL IN port on the ground unit by using the training port output cable and remote control connection cable. The supported remote control includes: Futaba, Spektrum, Devention and JR remote controller. Refer to the corresponding remote controller manuals for detailed usage. Two remote controllers can be connected to the ground unit at the same time, followthe illustration below for the connection: Red jack connects to the remote controller for the aircraft. Black jack connects to the remote controller for the gimbal. 14

Transmitter Configuration Refer to your own remote controller for reference. The below configuration process is based on Futaba T8FG as the example: 1. Switch off the RF option. The below procedure takes the Futaba T8FG as the example: a) Press and hold the [RTC] button to switch on the remote controller. b) Enter [POWR MODE] menu, select [RF OFF]. POWER MODE RANGE CHECK RF OFF RF ON c) RF indicator turns off and configuration success. 2. Set the [TRAVEL]value of each channels at the range within 100. The below procedure takes the Futaba T8FG as example: a) Double click the [LINK] button to enter [LINKAGE MENU], select [END POINT] option. b) Enter [END POINT] menu, set the [TRAVEL] value of each channels at the range with 100 as the below table shows: 15

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 Caution In some cases (namely for Futaba T8J remote controller), even though the [TRAVEL] value has been set to 100, but the actual output value may exceeds 100. The inconsistent value can be observed out by checking the [SERVO] in the Linkage show as below (actual GUI may vary from the models). SERVO OFF DG1 DG2 1 2 3 4 5 6 7 8 -100 -100 +100 -100 -100 +0 +0 +0 To prevent this situation, you must double check that the actual [TRAVEL] value does not exceed 100,otherwise you should re-configure the value until the requirement of the value is met. Video Connection Both HDMI and USB port can output video to the device, however, the selection of the output option is mutually exclusive. Select the video output base on your video device. Connect HDMI supported monitor to HDMI OUT port in the ground unit for HDMI viewing. (Coming soon) Connect smart phone to USB port on ground unit using USB cable. Use the DJI Lightbridge One app to view video and OSD information from the flight control system in real time.。The below illustration uses the USB port connection as the example. 16
