4、Function and application
4.1 Function
The main functions of LSD1XX A series products are distance measurement, input setting, and comprehensive
judgment of vehicle entry and exit process and dynamic separation of vehicles by measuring vehicle width and
height information. LSD1XX A series radar is connected to the upper computer through Ethernet cable, and the
data graphs and measurement data can be displayed through the upper computer software.
4.2 Measurement
4.2.1 Distance measurement（Apply to LSD102A、LSD121A、LSD105A、LSD151A）
After the radar is powered on and passes the system self-test, it starts to measure the distance value of each
point within the range of - 5 °~ 185 °, and output these values through the Ethernet interface. The default
measurement data is 0-528 groups, corresponding to the distance value in the range of - 5 °~ 185 °, which is in
hexadecimal format, and the unit is mm. For example:
Fault report
Receive data frame ：02 05 00 FE 00 FE 19 FE DB FE 01 02 F9 02 DE 02 E5 02 DE 02 E5 02 E5 02 E5 02

6.2 Port settings change
If you need to change the port IP address or port number, you can connect the upper computer with Ethernet
and change it through the upper computer software. The login permission can only be changed when it is a
technician (user name: admin, password: gtek2017).。
6.2.1 Change through system configuration
It can be modified in the [system configuration] dialog box in the upper computer software, and the specific.
operation is shown below：

第12 页
6.2.2 Change by sending command
You can also change the IP address and port number by sending a command, as follows：
The communication setting start character is：0x02，0x57，0x03，The command format is as follows：

8、Installation
8.1 Installation precautions
In the outdoor working environment, the lnd1xx should be installed with a protective cover to
avoid the internal temperature of the sensor rising rapidly due to direct sunlight。
Do not install the sensor with over vibrating or swinging objects。
Lnd1xx shall be installed away from the environment with moisture, dirt and danger of sensor
damage。
In order to avoid external light source such as sunlight, incandescent lamp, fluorescent lamp,
strobe lamp or other infrared light source, such external light source shall not be within ±5 °of
the detection plane。
When installing the protective cover, adjust the direction of the protective cover and ensure it is in face of the
lane, otherwise it will affect the accuracy of measurement
The rated current of single radar power supply shall be ≥3A（24VDC）。
The same kind of light source interference shall be avoided. When multiple sensors are installed
at the same time, the following installation methods shall be followed
a. Install isolation plate between adjacent sensors。
b. Adjust the installation height of each sensor so that the detection plane of each sensor is not
within ±5 degrees of each other's detection plane。

第15 页
c. Adjust the installation angle of each sensor so that the detection plane of each sensor is not
within ±5 degrees of each other's detection plane。
8.2 Installation method

9.2 Troubleshooting
9.2.1 Parameter configuration fault
Reconfigure the working parameters of the radar through the upper computer and transmit them to the
machine。
9.2.2 Front lens cover fault
The front mirror cover is an important part of LSD1xxA. If the front mirror cover is polluted,
the measurement light will be affected, and the measurement error will be large if it is serious.
Therefore, the front mirror cover must be kept clean. When the front mirror cover is found dirty,
please use a soft cloth dipped with neutral detergent to wipe in the same direction. When there are
particles on the front mirror cover, blow them off with gas first, and then wipe them to avoid
scratching the mirror cover.
9.2.3 Measurement reference fault
The measurement reference is to verify whether the measurement data is valid. If there is a fault,
it means that the measurement data of the machine is not accurate and cannot be used any more. It
needs to be returned to the factory for maintenance.
9.2.4 Motor fault
Failure of the motor will cause the machine to fail to scan for measurement or result in
inaccurate response time. Need to return to factory for maintenance。
9.2.5 Communication fault
Check the communication cable or machine failure
9.2.6 Output fault
Check the wiring or machine failure
