1. 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；
2.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;
3. 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：
1. Whether the baud rate of the device is consistent with that of
the E11.

2. E11 parameter settings can be registered in the browser to ensure that
all parameter settings on the device and E11 terminal are consistent.
3. 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 configuration using
1. 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.
2. 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 center
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.9 www.chinowing.com

● 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;

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;

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

www. chinowing. com

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.

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 WIFI
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.
