Data
The data transmission between the rangefinder and the upper computer includes the following contents:
● Control command: including single, 1Hz ranging instruction, 5Hz ranging instruction, query instruction, etc;
● Return data: including distance information, ambient temperature, rangefinder status, etc.
The data exchange between the rangefinder and the upper computer adopts RS422/TTL (two-choice 1), and its characteristics are as follows:
● Baud rate: 38400 (factory)/9600/57600/115200;
● Byte structure: low order in front, high order in back;
● Byte composition: 1-bit start bit, 8-bit data bit, no check, 1-bit stop bit.
Information
The format of the control command information is shown in the following table.

Baud Rate Settings
Baud rate setting operation method:
A.send "0x 55 0xF6 0x 00 0x 60 0x 96 0xXX" command to the laser range finder, I .e. set the baud rate to 9600bps; The rangefinder returns "CC 01 19 00 01 00 00 00 60 00 00 00 79 55", "0x 00 0x 60" indicates that the current baud rate has been set to 9600bps;
B.Send "0x 55 0xF6 0x 01 0x 80 0x 77 0xXX" command to the laser rangefinder, I .e. set the baud rate to 38400bps; The rangefinder returns "CC 01 19 00 01 00 00 01 80 00 00 00 00 98 55", and "0x 01 0x 80" indicates that the current baud rate has been set to 38400bps;
C.Send "0x 55 0xF6 0x 02 0x 40 0xB4 0xXX" command to the laser rangefinder, that is, set the baud rate to 57600bps; The rangefinder sends back "CC 01 19 00 01 00 00 02 40 00 00 00 00 5B 55", and "0x 02 0x 40" indicates that the current baud rate has been set to 57600bps;
D.send "0x 55 0xF6 0x 04 0x 80 0x 72 0xXX" command to the laser rangefinder, I .e. set the baud rate to 115200bps; The rangefinder returns "CC 01 19 00 01 00 04 80 00 00 00 9D 55", "0x 04 0x 80" indicates that the current baud rate has been set to 115200bps.
