Sequence description:The serial number of the terminal pins of the interface is 1 to 6 from top to bottom.
Laser ranging module adopts serial communication mode,the default baud rate is 115200bps.
Data format:eight bits of data,one start bit,one stop bit,no parity check.The data consists of header bytes,command part,data length,parameter part, and check bytes.
Communication mode:master and rangefinder adopt the master-slave communication mode,the master sends the control command to the rangefinder,and the rangefinder receives and executes the command.The range finder sends back the data and status of the range finder according to the range finder period,and the communication format and command content are shown in the following table.
