Newcon Optik LRF MOD 4EC - Manuals

4 Principle of work The Modules send invisible, eye safe laser pulses to the target. Pulses reflected from the target are captured and processed by the digital circuitry. The time-of-flight delay between the sent and received pulses allows calculating the distance to the target. A built-in digital c...

9 Interface RS 232 interface. Power External power requirement 9V DC, 300 mA The unit is fully operational when voltage is higher than 7V. A ‘ LOW BATTERY’ warning is displayed when voltage falls below 7.2V. Environmental Operational temperature range Storage temperature range -25 / +50ºC (-13 / +12...

10 5. OPERATION INSTRUCTIONS Maximum distance Though maximum measurement distance depends on target reflectivity, weather conditions and other conditions, for most targets the unit will provide accurate ranging for up to 3,000 meters. In good conditions a highly reflective target can be measured up ...

11 The correspondence between the pressing of the buttons and the signals sent via RS-232 is described in Interconnectivity, chapter 7. The rest of this manual describes measurement procedures and setting measurement parameters through pressing of the buttons. Measurement procedure When the Module i...

12 Target selection logic On its way towards the target, laser beam may reflect from various objects, thus decreasing ranging accuracy. The smaller, the farther, and the less reflective is the target – the higher is the possibility of obtaining an incorrect measurement. To improve accuracy the unit ...

19 Compass calibration If the Module was exposed to a strong magnetic field or was not in use for a long time, the compass accuracy may diminish. To bring the compass into working condition: ƒ Select Cd 17 in the Setup mode ƒ Keeping the unit horizontally, perform one full rotation around vertical a...

20 ƒ Pressing the A button will activate shown on the LCD communication format. Gating mode In this mode the gating function is activated: user can set the minimal distance to the target; reflection from any object closer than the gating distance will be ignored. The Gating feature helps measuring r...

21 Data Recall mode In the Data Recall mode results of the last 10 measurements can be displayed. Measurement results are saved in on-board memory in sets depending on the parameters set for measuring, for instance, if only distance is measured - the set will consist of one number, if distance and a...

23 6. BEST MEASURING TECHNIQUE Laser range finder module measures distance by catching a laser beam reflected from the target. Everything that improves reflection increases the measurement reliability and maximum range. 1. Aim at a surface on the target that is closest to the perpendicular to the la...

25 7. Interconnectivity The unit supports RS-232 interface. Physical connection is performed through a connector specific to each order. The default connectors are described in Specifications. Connecting to computer The communication port must be initiated prior to connecting the unit. Data is trans...

26 The data string has the following structure (in Hex): b1 b2 b3 E4h b5 E4h 0Dh 0Ah, where: b1 – type of measurement; b2 – sign of measurement (1 – minus, 2 – plus); b3 – LSB of result; b5 – MSB of result Result of measurement = MSB * 256 + LSB In both standard modes, when three parameters are meas...
