Overview
Industry drone market is developing very fast in recent years. The fight time and distance of drones are
getting longer and longer. VDC-30, a long-range wireless transmission system, is designed for VTOL fixed
wing and other long-range drones. The system can transmit video, fight control data, gimbal control data,
and RC data simultaneously. With the advantage of high level intergration and powerful function, VDC-30 is
a typical good product to meet long-range transmission requirements.
There are three ethernet ports in VDC-30. Users can connect it to ethernet gimbal and other payload
simultaneously. If you want to connect HDMI/SDI/AV port payload, we have MF05×MF08 to meet your
needs. You only need one single switching cable to connect VDC-30 and MF05. And the switching cable is
in the accessory box. For more information, please refer to the relevant section below. There are two UART
port——UART1 and UART2. Two protocols, Mavlink and Transparent, are supported. Users can make
changes easily through Maestro Assitant or Webpage. There are two SBUS——SBUS_IN and SBUS_OUT
for RC data transmission.
There are two frequency bands——800MHz and 1.4GHz. Users can choose according to their needs.
Please choose the suitable frequency band according to local regulations.
The weight of VDC-30 is 143g, making it very suitable for long-range drones. With advanced radio
frequency and encryption technology, VDC-30 can achieve long distance secure transmission. The maxium
transmission distance of VDC-30 can reach 34km*1.
We are going to open up the SDK in VDC-30 platform. Users can easily complete secondary development.
For more information of SDK, please follow our official website. The software SDK and examples will be
continuously updated.
*1 Test under LOS and no interference conditions.

Installation
Air
Ground
1.Installing the air unit on your drone
Fixed the device and RF cable on your drone. Install the antenna. Pay attention to the connection of the
antenna to tighten. Make the antenna downward. There is no metal or shielding within 20cm of the antenna.
2.Connecting the gimbal
Connect the gimbal to one ethernet of VDC-30. Connect UART1 to flight control. If you need to control the
drone with RC, please connect SBUS_OUT of VDC-30 to flight control SBUS IN.
Attention: If your gimbal only has HDMI/SDI/AV interface, please refer to the section of “VDC-30 with M05E”.
Do not put the antenna near the motor or ESC, otherwise the device will be interfered.
1.Connect the antenna
Connect the fiber glass antenna which was supplied along with the device to the ground unit. They have
common port—SMA. Make sure to tighten the joint. The 2 fiber glass antenna should be 1.5m apart.
Connect the RC receiver and other cables.
Connect the RC receiver SBUS output to the ground unit
SBUS_IN and then connect the power cable.
2.Connect to the Ground Station
The VDC-30 ground station can be connected to the
Ground Station with ethernet or UART.
Get Video
You can get video via RTSP, and decode the video with
video decoding software such as VLC. Also, you can get
video using Mission Planner and QGC.
Get data
1.You can get data from ground unit via UART1 and
UART2. Maybe you need a UART to
USB converter.
2.You can get data from Ethernet port using UDP/TCP
protocol.

Quick Start
1.Preparing
Make sure all the connections are ready, including the antenna, Ethernet cable and so on.If you connect a
ethernet gimbal to VDC-30 air unit, the GH1.25 interface is recommended for high reliability.
2.Power on
The DC voltage is 9~28V. After power on, the POWER LED will be solid green.
Any question, please refer to the FAQ. It takes 15 seconds to start up. After the system starts, the wireless
transmission can be established.
3.Using PC to get video from ethernet gimbal.
Connect gimbal×VDC-30 and PC as shown above×
Attention×Please ensure that gimbal and PC on the same network segment. The default IP of VDC-30 is
