Operating Steps
Connection
Connect the sensor to a serial port of the computer (or other device that has serial ports), then connect to a power port of the adapter with special data cable.
Single Trigger Measuring Mode
Send a command “O” (ASCII) by computer to turn on the sensor. Then sensor will emit a laser beam and prepare for working, and return the data “ – – – – ” (ASCII) to the serial interface. 4.2.2.2 Send a command “O” (ASCII) again to the sensor to start to measure distance. The sensor will return the measured data like “ XXXXXX” (ASCII) to the serial interface and turn off the laser beam when it finishes a single measurement. 4.2.2.3 Send a command “U” (ASCII) to turn off the sensor.
Continuous Measuring Mode
Send a command “O” (ASCII) by computer to turn on the sensor. Then the sensor will turn on the laser and prepare for working, returning the data “ – – – -” (ASCII)to the serial interface. 4.2.3.2 Send a command “C” (ASCII) to the sensor. The sensor will begin to measure continuously after 2 seconds when it got the command and return the data continuously like “X” (ASCII). If the sensor can’t get any available data, it will return “ – – – -” to the serial interface. 4.2.3.3 Send a command “U” (ASCII) to turn off the whole sensor (include both of laser unit and measuring unit).
Input and output
Communication settings
Baud rate: 9600 bps, Parity bit: None, Data bits: 8, Stop bit: 1
Input frame format
There is only one byte in every input frame. Users could send different commands to the sensor for different purpose, the functions of command are shown in the following table
| HEX | 0X4F | 0X43 | 0X55 |
|---|

Output frame format
Digital output data is displayed by ASCII code, there is 7 bytes in every data frame. The frame header is 0XFF, the next bytes meant measured distance numbers (unit: mm). A: hundreds of thousands, B: tens of thousands, C: thousands, D: hundreds, E: tens, F: ones.(Notice: If any byte in a data frame is not used, the sensor will return 0X20 in that byte.)
| Header | A | B | C | D | E | F |
|---|---|---|---|---|---|---|
| 0XFF | hundreds of thousands | tens of thousands | thousands | hundred s | tens |
ones
The mapping table of HEX and number codes:
| HEX | 0X30 | 0X31 | 0X32 | 0X33 | 0X34 | 。。。 | 0X37 | 0X38 | 0X39 | 0x2D | 0X20 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| number | 0 | 1 | 2 | 3 | 4 | 。。。 | 7 | 8 | 9 | – | space |
For example, if the measured distance data is 3456mm, then the sensor will return data as” 3456″(HEX: FF 20 20 33 34 35 36). Or the measured distance data is 123456mm, then the sensor will return data as “123456”(HEX: FF 31 32 33 34 35 36). If the sensor couldn’t get any available data( out of measurement range or measured in blind zone), it will return “ – – – -”(HEX:FF 20 2D 2D 2D 2D 20) to the computer.
Troubleshooting
Factors affecting the measurement range Laser distance sensor is a new non- contact optical measuring equipment. Its measuring range and accuracy will be effected by many external environmental factors. So the actual measuring result might be different with typical value which is measured in a standard environment. The following factors will effect actual measuring range:
Effect Factors
|
Increase measuring range
|
Decrease measuring range
---|---|---
Surface of target
|
Bright and smooth surface with good reflection, like target plate
|
Deep color and rough surface, like green or blue target surface
Air visibility
|
Clean air
|
Dust, fog, storm and rain, snow
Ambient light
|
Dark environment
|
Target exposure to strong light, like sunlight in midday
Laser emission
|
Laser emission lens and protection glass keep clean and
smooth
|
Laser emission lens and protection glass get dirty or
scratched
In conclusion, the best measuring result will be happen in a dark environment and with a good reflection target. We strongly suggest to use a target plate when laser distance sensor works in a poor environment. We also suggest to keep laser emission lens and protection glass clean with a soft cloth before start to using.
