Note: For example, the data ID 0x401 received on the 485 bus: FA 01 80 66 7F CA 00 FE indicates
that the radar gives early warning, the obstacle is in front of 10.2m, the speed is -5.4m /s, and
the negative sign indicates approaching to the radar
Note: This radar needs to be connected to the vehicle 485 bus to obtain the vehicle speed from the
bus. When the vehicle speed is greater than the starting speed, the radar will start to work. For the
convenience of customer testing, the starting speed of the radar is 0 by default. If the starting speed needs
to be set, the starting speed can be set with 485. The format of the set protocol is shown in the figure below:
