Page 10: General Description
General Description The AR1000H is a laser diode based distance measurement sensor for ranges up to 118 feet (30m) on regular surfaces and up to 500 feet (150 m) using a reflective target. The accuracy is generally specified with a linearity of +/- 0.08 inches (2mm). Linearity will vary depending on temperature and surface reflectivity of the target surface. -
Page 11: Installation
2.3. Installation The AR1000 sensor is typically installed by affixing the sensor to a machined bracket with bolts through the four mounting holes in the sensor. Their location is shown in the mechanical drawing above. The laser should be aimed at a target such that the distance from the reference point to the target can be meausured. -
Page 12: Sensor Maintenance
2.5. Sensor Maintenance The AR1000 sensor requires little maintenance from the user. The sensor lens should be kept clean of dust buildup as a part of regular preventative maintenance. Use compressed air to blow dirt off the window or use delicate tissue wipes. Do not use any organic cleaning solvents on the sensor. -
Page 13: Installation And Checkout
Installation and Checkout 3.1. Mounting Mount the sensor in such a way that the case is not twisted or warped. Using three hard points along the front and back edges or a slightly compliant mounting system are the best methods. Do not clamp or squeeze the sensor case excessively. -
Page 14: Standalone Cabling
3.2.1. Standalone Cabling To use the AR1000 without a serial connection to a host computer, the only connections necessary are the power and ground wires, the analog output wires, and optionally the alarm output wire connecting to your data display, recording, or control equipment. See Signal and Power Interface (section 4) for wire connections. -
Page 15: Power On
3.3. Power On Connect a 15 volt power supply to the power and ground lines of the sensor cable. See Signal and Power Interface (section 4) for wire connections. Only the power and ground need be connected for operation in addition to the serial interface. Caution: be sure that the laser will not cause an eye hazard. -

Page 18: Shield (Clear)
Power supplies from 10 VDC to 30 VDC may be used. Higher voltages will result in excessive current drawn by the over-voltage protection circuitry and may cause permanent damage. Voltages less than 10 VDC may result in inaccurate measurement readings. With the use of the on-board heater, the AR1000 sensor uses 24 W of power at 24 VDC. -
Page 19: Alarm Output (White)
Figure 8 Wiring Diagram for Analog output The best conversion to voltage is obtained by connecting a 500-ohm load resistor (1/4 Watt minimum) between the red and blue wires at the measurement point. This gives a 2 volt to 10 volt output range. -
Page 20: Laser Trigger (Brown)
Figure 10 Wiring diagram for Alarm Output 4.1.6. Laser Trigger (Brown) The Brown wire is the Trigger input. It is normally left unconnected to enable the laser. The trigger input is used with the DF measurement mode or TM trigger mode setting in the AR1000. -

Command Description Sets current distance as offset Turns laser on Turns laser off Displays all parameter values Resets all parameters to standard values 5.1.2. Baud Rate (BR) The Baud Rate is selectable via the serial interface and it requires the host device to change its own Baud Rate after commanding the sensor to change. -
Page 23: Serial Data Units Or Scale Factor (Sfx.x)
The minimum value of 000001 can be reached before the sensor reports an E15 error (see Error Codes Section 5.3). A maximum signal strength value of 99999 may be reached before the sensor becomes overloaded with ambient light and reports an E17 error. Hexadecimal Notes: Hexadecimal output values are calculated on units of millimeters (mm) multiplied by the scale factor SF. -

Page 27: Analog Output Operation (Rb, Re, Se)
Analog Output Operation (RB, RE, SE) The analog output uses two wires. The output is Red and the return is Blue. The return wire is the power supply ground. The current loop output is always on. The analog output is updated with each sample measured. The analog output will deliver a current which increases linearly from 4 mA at the range beginning point to 20 mA at the range end point. -
Page 28: Alarm Output Operation (Ac, Ah, Aw, Se)
Alarm Output Operation (AC, AH, AW, SE) The alarm output uses the white wire in the basic configuration. Alarm output is also referred to as digital switching output. Users of the AR1000 laser sensor may wish to monitor the position of an object and receive an alarm if it moves beyond set distance limits. To do this, users establish parameters of a measurement window using commands AC alarm commence, AH alarm hysterisis and AW alarm width. -

Error Mode behavior for the alarm output (SE0, SE1 or SE2) The factory default setting is SE1 The AR1000 alarm output can be configured to output different alarm outputs for special error conditions that correspond to Error Messages E15, E16, E17 and E18 (See Error Messages section 5.3 for more information). -
Page 31: Performance Optimization
Performance Optimization 8.1. Measurement Modes The AR1000 will not begin measuring and outputting distances until the user selects a measurement mode. Once initiated, the distance reading will be output on both the serial and analog lines. Users may select among several modes that will optimize the sensors’ speed or accuracy performances for the specific measuring application. -
Page 32: Hardware Trigger Mode (Df)
ft/sec (4 m/sec). For higher rates of measurement, preceding measured values will be included in the process to calculate a currently measured value. 8.1.5. Hardware Trigger Mode (DF) This serial command enables the Trigger input to cause single sample to be measured and outputs to be generated. -
Page 33: Set Zero Point (Ofx)
8.4. Set Zero Point (OFx) Factory default setting is 0 (the sensor’s natural zero point) The OF command allows users to manually set a zero point anywhere relative to the sensor’s natural zero point. The commanded zero point can be a negative number. The parameter units for OF are dictated by the scale factor (SF). -
Page 34: Set Heater On Temperature (Hox)
8.6. Set Heater ON Temperature (HOx) This parameter is only available in the AR1000H laser sensor. Factory default setting is 3 (corresponding to 3°C) The HO command determines the low temperature below which the AR1000H sensor’s internal heater will automatically turn on. A temperature sensor inside the AR1000H monitors the internal temperature of the device and compares it to the HOx value. -
Page 35: Trigger Mode Optimization
Trigger Mode Optimization Trigger mode is only available in the standard AR1000 and NOT available in the AR1000H (heater) sensor version. The AR1000 can operate with a hardware trigger that has been connected according to the diagram in Section 4.1.6. To operate with an external trigger, the AR1000 must be configured in the Trigger Measurement Mode (DF). -
