Lightbridge 2 FAQ

The following enhancements have been made to the DJI Lightbridge 2:
A new SDI output port has been added. The Remote Controller is now integrated into the Ground System, so that you don’t need to buy an additional Remote Controller.
Transmission latency has been reduced to as low as 50ms. Transmission range has been extended to up to 5km. Intelligent, adaptive wireless technology has been added for increased transmission reliability. Picture-in-Picture output support has been added.

The Serial Digital Interface (SDI) is capable of transmitting High Definition digital video via a coaxial cable. Compared to HDMI output, the SDI boasts longer transmission distance and more stable signal. It is the most widely used interface in the Broadcasting and Television industries. The SDI port included with the DJI Lightbridge 2 solves the problem of unstable signal transmission, improves compatibility between devices, and removes the need for extra adapters.
No.The Remote Controller is now integrated into the Ground System. There is no need to buy extra Remote Controllers.
No, the DJI Lightbridge 2 is not compatible with the Inspire 1.
No, the DJI Lightbridge 2 has a brand new algorithm for optimized wireless transmission. It cannot be used with the original DJI Lightbridge.
No, the DJI Lightbridge 2 air system has a working voltage of 3S while that of the DJI Lightbridge is 3S~6S. Please make sure the voltage is set to 3S when the DJI Lightbridge 2 with the cable from the DJI Lightbridge.
The AV input port of DJI Lightbridge 2 air system is also used for power supply, which is different from the previous generation. Make sure to avoid short circuiting this port during installation and use.
50 meters.
The built-in 2S 6000mAh battery gives the Ground System a working time of 4 hours.
The mount can hold an iPad Air or other similar-sized tablet. Tablets should be no more than 170mm wide.
The latest version of the DJI GO app for iOS and Android should be used with the DJI Lightbridge 2.

First, mount the Antenna Extension Cables to the Air System. They will make a clicking sound when successfully installed.
Then, connect the Antenna Extension Cables to the antenna of the Air System and install the Antenna Mounts to the landing gear of the aircraft. For optimal signal performance, adjust the Antenna Mounts to make sure that they are perpendicular to the ground when the landing gear is retracted.
Use cable ties to fix the Antenna Extension Cables.

After finishing setting up the Air System, connect the A2 to your computer and use the A2 Assistant Software to map the channels of the Remote Controller. Map the Return to Home function to channel 6, which corresponds to the Return to Home button.
You can either use USB and HDMI output or USB and SDI output simultaneously. The HDMI and SDI output ports cannot be used at the same time. You can choose the output port configuration in the DJI GO app. The default output port is HDMI.
Please move to a location with less electromagnetic interference and/or choose channels with suitable video transmission quality in the DJI GO app. If the live view is still not clear, you can use “Signal Diagnosis” in DJI GO app to check whether the antenna is functioning normally or not.
The red color displayed by the Air System’s video light signals normal functioning. The video light only shows the working condition of the LB ports (HDMI/AV port) while the condition of the EXT port (Gimbal port) is determined by the gimbal light.

First, make sure you that you have configured the output port to correspond with the monitor.
Then, make sure you choose the correct input port: LB for direct input, EXT for gimbal signal and PIP_LB/PIP_EXT for PIP dual video input.
If the configuration of the app is correct, please check that the settings of the camera and ensure that the gimbal cable is not loose or broken.

Reboot both devices and link them again. Please ensure that the linking process is being performed in an environment with low interference.
Select “Low Latency” in the DJI GO app and ensure that there is no strong interference nearby. Alternatively, manually adjust to a channel without interference and choose the suitable video transmission quality.

First, make sure that the aircraft is flying in an environment with relatively low interference or adjust to a channel without interference and choose the suitable video transmission quality (in the DJI GO app).
If the loss of signal continues, you can use “Signal Diagnosis” in DJI GO app to check whether the antenna is functioning normally or not.
