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 an adapter with a special data cable.

Single Trigger Measuring Mode

Send a command “O” (ASCII) or “0X4F” (HEX) by computer to turn on the sensor. The sensor will emit a laser beam prepare for working, and return the data “FF 00 0A 0A 0A 00” to the serial interface.
Send a command “O” (ASCII) or “0X4F” (HEX) again to the sensor to start to measure distance. The sensor will return the measured data like “FF XX XX XX XX XX” to the serial interface and turn off the laser beam when it finishes a one-time measurement. For example, if the measured distance is 123.4m, the computer will receive data like “FF 00 01 02 03 04”.
Send a command “U” (ASCII) or “0X55” (HEX) to turn off the sensor. 4.2.3 Continuous Measuring Mode

Send a command “O” (ASCII) or “0X4F” (HEX) by computer to turn on

the sensor. Then the sensor will turn on the laser prepare for working, and return the data “FF 00 0A 0A 0A 00” to the serial interface

Send a command “C” (ASCII) or “0X43” (HEX) to the sensor. The sensor will begin to measure continuously after 3 seconds when it gets the order, and return the data continuously like “FF XX XX XX XX XX”. If the sensor can’t get any available data, it will return “FF 00 0A 0A 0A 00” to the serial interface. 4.2.3.3 Send a command “U” (ASCII) or “0X55” (HEX) to turn off the whole sensor (including both of laser unit and measuring unit).

Troubleshooting

Factors affecting the measurement range
The laser distance sensor is a new of un-contact optical measuring equipment. Its measuring range and accuracy will be affected by many external environmental factors. So actual measuring result might be different from a typical value that is measured in the standard environment.

The following factors will affect the 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 colour 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 lenses and protection glass get dirty or scratched

In conclusion, the best measuring result will happen in a dark environment and with a good reflection target. We strongly suggest using 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 starting to sing

Error code display
All error codes are either displayed with “FF AA 00 XX XX XX”. The following errors can be corrected

Display Notice	Cause	Correction
FF AA 00 02 00 04	Calculation error	Repeat procedure
FF AA 00 02 05 02	Temperature too high	Let device cool down
FF AA 00 02 05 03	Temperature too low	Warm device up
