Side View [ 1] [1] [ 2] HDMI IN Port Connects to the HDMI input device.
[1] Power Adapter Port(11V~26V) Connect the power adapter or a 3S~6S battery to this port to charge the built-in battery. If use a 3S~6S battery, the ground end comes with the protection function, which prevents the 3S~6S batter from over discharge. When the ground unit is connected with the external power adapter or battery, the built-in battery disables itself and switch to external power source. Beware of the input voltage range, do not exceed the operating range (11~26V).

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.
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.
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.
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) 2. RF indicator turns off and configuration success.

operation is completed. (3) When the ground unit is receiving signals, both the antennas stop transmitting signals and start receiving signals. When the ground unit is transmitting signals, the antennas stop receiving signals and one of the antennas starts transmitting signals.
DJI LIGHTBRIDGE App Usage DJI LIGHTBRIDGE App can display OSD information feed by the flight control system.

Appendix Re-link Follow the below instruction to re-link the air unit and the ground unit when the initial linking is failed. 1. Maintain a distance of 0.5m to 1m between the air unit and the ground unit, power on the air unit and then the ground unit. 2. Use a pin to press the [LINK] button on the air unit. Press and hold on for 5 seconds then release. 3. When re-link is finished, The [CONTROL] indicator on air unit turns solid green. Recharge Ground Unit Unit 1.
