1OPERATION UNDER WINDOWS
1.1 Device Connection
When TEA is evaluated and developed under windows, TEA and PC need to be interconnected.
The specific process is as follows:
FIG 1 YDLIDAR TEA DEVICE CONNECTION
Connect the RJ45 port on one end of the device cable to the network port on the PC, set the
device and PC to be on the same network segment. The DC port is connected to the power socket
through the 12V-1A power adapter.
1.2 Network setting
TEA Initial network parameters have been set before delivery:
IP address: 192.168.0.11
Subnet mask: 255.255.255.0
When connecting to the lidar for the first time, the network parameters of the PC and lidar must
be set in the same network segment and do not conflict with each other. As follows:

When using the visualization software EaiLidarTest to check the point cloud data, the user need
to penetrate the firewall of the operating system to obtain the data. It is recommended to add the
software to the list of allowed software in the firewall. Operation method: “Control Panel”- “System
and Security”- “Allow applications to pass through the firewall”, allowing EaiLidarTest to pass
through the firewall.
1.3 How to Use EaiLidarTest
YDLIDAR provides EaiLidarTest, a point cloud data visualization software for TEA real-time
scanning. Users can use this software to visually observe the TEA scanning map: YDLIDAR
provides TEA real-time point cloud data and real-time scanning frequency. At the same time, the
scanned data can be saved offline to an external file for further analysis.
Run the evaluation software: EaiLidarTest.exe, select the corresponding model number, click
“Login”. Meanwhile, users could choose language based on our personal situation (“Help”in the
upper left corner).

Start Scanning
Click "Start/Stop" in the Stopped state. Click “Start” button to start scanning and display the
environment point cloud. The angle and distance information of the red line position will be
displayed in the upper left corner (unit: mm). Click “Stop” button to stop it. as shown below:
FIG 8 LIDAR SCANNING POINT CLOUD DISPLAY
Select one as needed, move the mouse to the testing position, right-click on the pop-up menu,
and select “锁定光标”.

FIG 9 LOCKING MOUSE TRACKING
Move the mouse to the testing position, right-click the pop-up menu, and select “显示强光图”.
The main window displays the intensity values of a total of 100 points on the left and right sides of
the mouse lock position.
FIG 10 SHOWS THE LIGHT INTENSITY HISTOGRAM
Data Storage
During lidar scanning, click in the Bottom right corner of the main window, select “Export
data/Export data (sorted by angle)”, and save point cloud data according to the prompts. Then the
system will save the point cloud information scanned in a circle.

FIG 11 SAVE DATA
Playback and Recording display Mean and Standard Deviation
Select “Record/Stop”in the bottom left coner of main menu.
FIG 12 RECORD AND PLAY
The main window is displayed as follows:
To record lidar data, click to start recording, and click to stop recording.
In non-scanning mode, click to start play.
The play process is as follows:

FIG 14 WAVE FILTERING SETTING
Network Configuration
Click on the bottom right corner of the main window to configure the device network
parameters, which can be used to set the device IP address, TCP port, and UDP port. After changing
any of these configurations, you need to click the “Confirm”button to save the settings. After the
device restarts, the settings will take effect.

2LINUX ROS OPERATION
There are many Linux distributions, and this article only takes Ubuntu 18.04 and Melodic
version ROS as examples.

2.1 Device Connect
Under Linux, the interconnection process between TEA and PC is consistent with the operation
under Windows, see Device Connection under Window.
2.2 Compile and Install YDLidar-SDK
Ydlidar_ros_driver depends on the YDLidar-SDK library. If the user has never installed the
YDLidar-SDK library, or it has expired, the user must first install the YDLidar-SDK library. If the
user has the latest version of YDLidar-SDK installed, please skip this step, then go to the next step.
2.3 ROS Driver Installation
1) Cloning GitHub's ydlidar_ros_driver package:
2) Build the Ydlidar_ros_driver software package:
3) Package environment Settings:
Note: add a permanent workspace environment variable. It will be very convenient if ROS
environment variables are automatically added to your bash session every time you start a new shell:
4) Verify that your package path is set, echo the ROS_PACKAGE_PATH variable.
$git clone https://github.com/YDLIDAR/YDLidar-SDK.git
$cd YDLidar-SDK/build
$ cmake ..
$ make
$ sudo make install
$ sudo make install
$ git clone https://github.com/YDLIDAR/ydlidar_ros_driver.git
TIA_ros/src/ydlidar_ros_driver
$ cd ydlidar _ws
$ catkin_make
$ source ./devel/setup.sh
$ echo "source ~/ydlidar_ws/devel/setup.bash" >> ~/.bashrc
$ source ~/.bashrc
$ echo $ROS_PACKAGE_PATH
