150km digital video datalink for VTOL / UAV manual.

150km digital video datalink for VTOL/UAV Video/Data Wireless Transmission System.

As the UAV industry evolves, the demand for advanced communication systems grows. This technology promises to revolutionize long-distance UAV operations with reliable, high-quality video transmission. Recently, due to market demand, we've received many inquiries about our datalink's compatibility with various drone systems. Therefore, I'm writing this brief article to provide an overview and connection manual for our Mk100 pro (150 km datalink).

Overview 150km datalink (Mk100 pro/ Mk150 video datalink ).

1.1.0 Some common questions.

• Can we customize uncommon frequencies such as 700 MHz, 900 MHz, or other frequencies for long-distance video datalink systems?
• YES, it's very easy for us to customize it; we just need enough MOQ orders. we support any kind of customization.
• Does our datalink support the MAVLink (Micro Air Vehicle Link) protocol?
• YES! Our data link supports MAVLink and transparent protocols, which are the most popular and widely used. If you require other protocols, our R&D team can customize them for you.
• What about Ardupilot/PX4?
• support all of them.

1.1.1 interface Description

1.1.2 installation. (Air )

1.0 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.

1.1 Connecting the gimbal.

Connect the gimbal to one ethernet of MK100. Connect UART1 to flight control. If you need to control the drone with RC, please connect SBUS_OUT of MK100 to flight control SBUS IN.

Attention: If your gimbal only has HDMI/SDI/AV interface, please refer to the section of “MK100 with M05E”. When using the SBUS, please pay more attention to the power.

Do not put the antenna near the motor or ESC, otherwise, the device will be interfered.

1.1.2 installation. (ground )

1.0 Connect the antenna.

Connect the fiberglass antenna which was supplied along with the device to the ground unit. They have a common port—SMA. Make sure to tighten the joint. 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.

1.1 Connect to the Ground Station

The MK100 pro ground unit can be connected to the Ground Station with Ethernet or UART.

1.2 Get video & data

You can get video via RTSP, and decode the video with video decoding software such as VLC. Also, you can get videos using Mission Planner and QGC.

1. you can get data from the ground unit via UART1 and UART2. Maybe you need a UART to USB converter.

2. you can get data from an Ethernet port using UDP/TCP protocol.

2.1.0 MK100 Instruction

2.1 Make sure all the connections are ready, including the antenna, Ethernet cable, and so on. If you connect an ethernet gimbal to the MK100 pro air unit, the GH1.25 interface is recommended for high reliability.

2.2.Power on, The DC voltage is 9~28V. After power on, the POWER LED will be solid green. Any questions, please refer to the FAQ. It takes 30 seconds to start up. After the system starts, the wireless transmission can be established. After the chain is built, the current wireless signal strength, wireless signal-to-noise ratio, communication distance, and real-time data can be viewed on the LCD screen of the ground.

3. Using a PC to get video from the gimbal camera via an ethernet port. for HDMI, CVBS ports we suggest our MF05, CODEC module.

3.1 Connect gimbal、MK100 and PC as shown above.

Attention： Please ensure that the gimbal and PC are on the same network segment. The default IP of MK100 pro is in the table below. The network segment of the gimbal and MK100 pro datalink can be the same or different. MK100 pro datalink can transmit video and data transparently.

MK100?air?unit?default?IP : 192.168.1.200

MK100?ground?unit?default?IP : 192.168.1.236

Gimble camera IP :192.168.1. XXX

3.2 Get video: Users can get video on PC through the software provided by the gimbal manufacturer. Also, users can use some common software such as VLC. Take VLC for an example.

In the “open media” page, please input the following address： rtsp://192.168.1.36:554/stream0

You?can?get?the video?after?click?“play.

3.1.0 Let's discuss about Mission planner.

Follow the steps to use MK100 with Mission Planner：

1. Connect the UART1 of the MK100 pro air unit to the flight controller, such as Pixhawk. Connect the gimbal to one ethernet of MK100 pro.

2. Make sure all the air and ground cable connection is finished. Power on the system.

3. Install Mission Planner on your computer.

4. Set the IP address of the computer. Open “Network and Internet” setting.

Select “Internet Protocol version 4 (TCP / IPv4) properties”.

Change IP address to “192.168.1. xxx”（xxx is in 0～255 , you can't use IP 192.168.1.200 and 192.168.1.236, because these IP were set in MK100 pro datalink）

Attention： The IP “192.168.1. XXX” is just an example. You need to set up your

PC the same IP section as your gimbal.

3.2.0 Get data

There are three methods to get data from the MK100 pro ground unit, using Mission Planner：

• UDP port via Ethernet;
• TCP port via Ethernet
• UART (COM)

3.2.1 Get data from the UDP port.

open Mission Planner， select UDP， and click the “connect” button, it will bring up a new window ‘Listen port’， change the port to 14550（If the UDP port number has been changed on the web page, please fill in the new number. For more information, please go to the web page configuration）. Then click “OK”, Mission Planner will get flight data.

3.2.2 Get data from TCP port.

Open Mission Planner， select TCP, and click the “connect” button, it will bring up a new window ‘Listen port’， fill in the blank with IP: 192.168.1.236, remote port is 5760

(If the IP address and TCP port number have been changed on the web page, please fill in the new IP and port number. For more information, please go to the web page configuration）. Then click “OK”, Mission Planner will get flight data.

Open Mission Planner, select COM (Please check the COM number) and the right baud rate， click the “connect” button, Mission Planner will get flight data.

3.3.0 Get Video

When you open the Mission Planner, click Video and then Set GStream Source， as show below：

Input the address: rtspsrc location=rtsp://192.168.1.36/stream0 latency=0 ! decodebin ! videoconvert ! video/x-raw,format=BGRA ! appsink name=outsink

Attention: The IP“192.168.1.36/stream0”is an example of the gimbal, please use your own gimbal RTSP address

4.1.0 Improve RC controller distance through SBUS.

1.0 Connect air unit SBUS_OUT to flight controller RC IN. Using the SBUS cable in the accessory box to connect the air unit and the flight controller. The cable is 3 pins.

Attention： The SBUS_OUT port of the air unit is output. The maximum of +5V output current is 1A. If you don’t need the +5V, let it open. Do not take it as input. Otherwise, the stability of the system will be affected.

2.0 Connect the RC receiver to the ground unit Use the SBUS cable in the accessory box to connect the ground unit to the RC receiver.

Attention： The SBUS_IN port of the ground unit is input. The maximum of +5V output current is 1A. You can use it to power the RC receiver. Please pay more attention to the cable line order.
