Wiring diagram of E11 and V21

After the connection is complete, please refer to the following steps to check the connection status. (This step will have some differences due to different flight controllers)

E11 is connected to 7.4-24V DC power supply, and the POWER indicator light indicates that the transmitter is powered on normally; when the L2 indicator light is continuously on, it means that the LAN port self-test is normal working;
When the L3 indicator is always on, it means that the serial port module starts normally, and it can work normally after the self-test is completed;
Open the flight control ground station software, select the corresponding COM port, and connect to the flight control. If the flight controller is connected normally, it means that the data transmission link of the E11 module has been connected. If the connection fails, please check the following points:

Whether the baud rate of the device is consistent with that of the E11.
E11 parameter settings can be registered in the browser to ensure that all parameter settings on the device and E11 terminal are consistent.
Make sure that the RX of the flight controller corresponds to the TX of the E11, and the TX of the flight controller corresponds to the RX of the E11.

LAN and use of serial port

V21 video transmission and E11 routing IP address distinction

Type	IP address
V21 ground terminal	192.168.168.11
V21 airborne terminal	192.168.168.12
E11 serial port	192.168.168.19
E11 LAN*2	The device user accesses

All the above IP addresses in the E11 can be logged in and accessed in the browser of the PC to modify the parameter configuration.

In order to prevent users from problems such as not being able to search, not being able to ping, and not being able to open web pages in the application. After the hardware is connected, before use,

Check the computer first.

Turn off the computer’s firewall and antivirus software (usually in the control panel).
Turn off the network card that is not related to this test, and only keep a local connection or Wi-Fi wireless connection.
The IP of the computer must be set to a static IP in the same network segment as the IP of the V21, for example:
192.168.168.35.

LAN configuration using

After the LAN port of E11 is connected to V21, two IPC devices can also be connected. If the computer needs to access two IPCs at the same time, the IPC and the local IP of the computer must be set to the same network segment.
The LAN port of the V21 ground terminal is connected to the computer, please make sure that the IP address of the local connection of the computer and the camera are in the same network segment

① Open the computer network sharing centre
② Open the change adapter option

③ Select the local connection connected to the V21 ground terminal, right-click to view properties
④ Select the Internet IPV4 protocol, set a fixed IP, and the IP is on the same network segment as the camera, for example:
The camera IP is 192.168.168.100, except for setting the local IP to 192.168.168.xxx (0~255) 100, click “OK” after the change is completed.

⑥ Use streaming software such as VLC media player to capture and play video data

If the LAN port is connected by cable, the IP address of the V21 can be ignored when setting the IP when streaming video. Change the local IP of the computer to the same network segment as the IP camera;
It is recommended to set the ip network segment of the two LAN ports of E11 to 192.168.168.XX and V21 in the same network segment, so that the image and configuration data of the LAN port and video transmission can be obtained at the same time;

Serial port configuration using

The default baud rate of all serial ports of E11 is 115200, and the default IP address; the ground terminal is 192.168.168.19, working mode: the air terminal is TCP Server, and users need to use TCP Client mode to connect and access;

Serial port working mode independent port distinction

Type	Working mode	Local port	Level signal
E11	TCP Server	10	TTL
		20	RS232
		30	RS232

If you need to change other configurations, you can connect to the computer through the LAN port.

① The IP of the computer must be set to a static IP that is in the same network segment as the E11 serial port IP. After connecting to the LAN, open the network adapter and select the network adapter connected to the E11 serial port to set a static IP address, such as 192.168.168.34.

② Open the browser and enter “192.168.168.19” to connect to the ground terminal serial port module to enter the web page configuration screen. Username: admin Password: admin; After entering, the upper right corner supports switching between Chinese and English.

③The 3-way serial port setting corresponds to the E11 external interface: port 1 → TTL, port 2 → RS232, port 3 → RS232; if you need to change the baud rate as shown in the figure below, just enter the corresponding baud rate to save the setting, the baud rate supports 600 -230400bps;

④ Working mode Serial port working mode supports TCP Server, TCP Client, UDP, Http Client, WEB to Serial (Web socket) and other working modes.

Default working mode: The three local ports of the TCP Client on the ground terminal are 10, 20, and 30 respectively; Air end TCP Server local\remote three ports are 10, 20, 30 respectively

The ground terminal (TCP Client) can access any port of the air terminal (TCP Server) in the serial port assistant, and can support up to 8 TCP Client mode accesses at the same time. If the user computer is connected through the LAN port and can access any port at will, just fill in the port number of the remote (air terminal) in the port of the ground terminal.

If it is connected through the external interface of the device, the serial port signals at both ends of the E11 must be consistent, otherwise the communication cannot be performed.

⑤ In the advanced settings, you can change the module name, user name and password, and the default data reset time is 60 seconds.
Do not change this parameter.

⑥ Image transmission configuration, in the serial port configuration, you can click “jump” on the air end or ground end, and after clicking, it will automatically jump to the corresponding image transmission configuration login interface.

TCP serial port connection using

After connecting to the E11 network through the V21 (or a third-party network image transmission), the serial link data transmission can be performed through the TCP protocol or a virtual port.

Take TTL port 10 as an example, if you use the TCP protocol for communication, open the Mission Planner ground station, select the TCP communication mode, enter the serial port IP address of the air end 192.168. 168.19, Port number (you need to select the external interface corresponding to the communication of the air end), establish a connection (the baud rate does not need to be selected), if you are using RS232, the port number is 20 and 30;

The factory default baud rate of the E11 serial port is 115200, you need to set the flight controller or other equipment to 115200, and you can also log in to the Web to change the baud rate of the E11 serial port;

Use of virtual serial port connection

If you want to use the COM port for communication connection, you need to use the network virtual port tool to visualize the TCP protocol network connection into a COM port.

Install the network virtual port toolkit, click Add, and the Add Virtual Serial Port interface will appear, select an unused port number, select
the client for the network protocol, enter the IP of the air terminal and the corresponding port number for the target IP and port, and click OK
to see A new port ELTIMA Virtual Serial Port has been added in the device manager, this port is the serial port virtualized by the Wi-Fi network

After the virtual serial port is added, select the corresponding interface to connect to the flight controller, and select the corresponding COM port and baud rate on the computer to communicate.

The network virtual serial port tool can be downloaded from the official website “www.chinowing.com” download center.
When using the serial port on the computer side, the connection method needs to select the TCP Client mode to access the corresponding port communication of E11.

E11 One-to-one usage of E11 serial port module

When E11 is used as a pair, connect to the LAN ports of the V21 air end and the ground end respectively, and communicate after the V21 establishes a link. When E11 leaves the factory, the serial port default baud rate is 115200, and the default IP address is configured;and the default IP address is 192.168.168.18 for the ground terminal, 192.168.168.19 for the air terminal, working mode: the air terminal is TCP Server, and the ground terminal is TCP Client;
