Communication protocol

The data transmission between the rangefinder and the host computer includes the following contents:
Control commands: including starting ranging, continuous ranging, single ranging, query commands, etc.
Loopback data: including distance information, ambient temperature, range finder status, etc. The data exchange between the distance measuring machine and the host computer adopts 422 bus. The specific software communication protocol is as follows:
Communication format: 422 communication, baud rate 115200bps (can be changed according to customer requirements);
Data format: 8-bit data, one start bit, one stop bit, no parity check, the data consists of header byte, command part, data length, parameter part, check byte;
Communication mode: the main control and the distance measuring machine adopt the master-slave communication mode, the master control sends control commands to the distance measuring machine, and the distance measuring machine receives and executes the instructions. In the ranging state, the rangefinder sends back the data and status of the rangefinder to the upper computer according to the ranging cycle. The communication format and command content are shown in the following table.
