CONTROL FUNCTION

The laser rangefinder/illuminator can achieve the following functions through the serial communication interface:

2.1 Respond to laser ranging instructions and can stop ranging at any time according to the stop command;

2.2 During ranging, distance data and status information are output once for each pulse;

2.3 After starting continuous ranging at 1Hz, if no stop command is received, it will automatically stop after 5 minutes;

2.4 After starting continuous ranging at 5Hz, if no stop command is received, it will automatically stop after 1 minute;

2.5 It has a single ranging function;

2.6 It can set the illumination mode and encoding, and can output the selected settings;

2.7 Respond to laser illumination command, illuminate according to the set mode and encoding, and can stop illumination at any time according to the stop command;

2.8 If no stop command is received after starting the illumination, it will automatically stop after one illumination cycle;

2.9 During laser illumination, distance values and status information are output once for each pulse;

2.10 It can report the cumulative number of laser pulses emitted (not lost in case of power failure);

2.11 It can report the cumulative number of laser pulses emitted (not lost in case of power failure);

2.12 The information reported during ranging and laser illumination work includes pulse counting numbers;

2.13 Self-test and output fault codes:

2.13.1 Power-on self-test, including

2.13.1.1 RS422 serial port communication status;

2.13.1.2 High temperature alarm.

2.13.2 Start and cycle self-test, including:

2.13.2.1 RS422 serial port communication status;

2.13.2.2 High temperature alarm;

2.13.2.3 High temperature alarm.

Note: Laser rangefinders/illuminators can only detect charging/discharging and laser emission/non-emission faults when emitting laser beams. Therefore, the power-on self-test does not require detection of the above two types of faults. During startup self-test and periodic self-test, the laser rangefinder/illuminator reports the detection results from the last illumination or ranging.

2.2 Temperature warning output, expected performance during illumination or ranging.
