Use a target plate to increase the measurement range during daylight or if the target has poor reflection properties.

**In favourable conditions(good target surface properties, room temperature)up to 10m. In unfavourble conditions, such as intense sunshine, poorly reflecting target surface or high temperature variations, the deviation over distances above 10m can increase by ±0.15mm/m.

2 Operating Steps

2.1 Connect a sensor to the serial port of computer (or other device which have serial ports) and the power port of adapter with special data cable.

2.2 Trigger Measuring

2.2.1 Send the command “O” (ASCII) or “0X4F” (HEX) by computer to turn on the sensor. Then the sensor will turn on the laser and prepare for working, and return the data “FF 00 0A 0A 0A 00” to the serial interface.

2.2.2 Send the 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 XX” to the serial interface and turn off the laser when it finished one time measurement.

2.2.3 Send the command “U” (ASCII) or “0X55” (HEX) to turn off the sensor.

2.3 Continuous Measuring

2.3.1 Send the command “O” (ASCII) or “0X4F” (HEX) by computer to turn on the sensor. Then the sensor will turn on the laser and prepare for working, and return the data “FF 00 0A 0A 0A 00 00” to the serial interface

2.3.2 Send the command “C” (ASCII) or “0X43” (HEX) to the sensor. The sensor will begin to measure continuously after 3 seconds when it got the order, and return the data continuously like “FF XX XX XX XX XX XX”. If the sensor couldn’t get any available data, it will return “FF 00 0A 0A 0A 00” to the serial interface.

2.3.3 Send the command “U” (ASCII) or “0X55” (HEX) to turn off the whole sensor (include both of laser unit and measuring unit).
