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.

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:
