Page 8: Introduction
AR500 has a number of configurable parameters, but many applications can use the sensor in its default factory configuration. This manual contains information for a variety of AR500 sensor configurations that can be ordered from Acuity. Your specific AR500 model may not have all interfaces and functions described in this manual. -

Page 11: General Description
General Description The AR500 is an ultra-compact laser diode-based distance measurement sensor with available ranges covering 5 to 1000 mm. Consult the AR500 data sheet for exact model range availabilities. The accuracy is generally specified with an absolute linearity of +/- 0.10% of the span and a resolution of 0.01% of the span. -
Page 12: Installation
2.3 Installation The AR500 sensor unit is typically installed by affixing the sensor to a machined bracket with bolts through the two mounting holes on the side of the sensor. Their location is shown in the mechanical drawing in section Error! Reference source not found.. -
Page 13: Sensor Maintenance
2.5 Sensor Maintenance The AR500 sensor and module require 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 windows or use delicate tissue wipes. -
Page 14: Installation And Checkout
Installation and Checkout 3.1 Mounting Mount the sensor in such a way that the case not twisted or warped. Do not clamp or squeeze the sensor case excessively. If the case is distorted, the sensitivity and accuracy of the sensor may be affected. 3.2 Cabling for sensor unit The AR500 sensor has a multipurpose cable with 8 conductors (included). -
Page 15: Serial Connection To A Host Computer
The simplest way to connect the AR500 sensor to a PC computer for initial configuration or regular distance measuring is with the use of an Acuity Connectivity Kit. This is a sealed connection box which contains terminal blocks for each wire lead. It also has an AC power supply and a 2m RS232 serial cable for connection to a PC. -
Page 16: Signal And Power Interface

Connection and termination according to the instructions is essential for correct sensor operation. Read the wire descriptions for connection information. -
Page 17: Analog Output (Blue, Grey)
See Serial Interface Operation (section) for information on commands and data. The maximum baud rate is 460.8 KBaud for RS232 and 921.6 KBaud for RS485. RS232: RS232 is normally used for shorter distances of communications and slower data rates. RS232 allows only one transmitter and one receiver per network. -
Page 18: Current Loop
4.4.1 Current Loop Figure 3 The current loop connection scheme is shown in the . The value of load resistor should not be higher than 500 Ohms. To reduce noise, it is recommended to install RC (resistor / capacitor) filter before the measuring instrument. -
Page 19: Logic Outputs (Pink, Grey)
4.5 Logic Outputs (Pink, Grey) The Pink wire is a multi-purpose logic output / interface that can operate in four distinct modes. The functionality can be configured according to the instructions in section 7 . Functions include distance alarms, multi-sensor synchronization, setting of Zero Point via hardware control and control of the laser ON / OFF state. -
Page 20: Serial Interface Operation
Serial Interface Operation This section refers to serial communication protocols for both the Sensor and Module versions of the AR500. 5.1 Communications Protocol and Syntax Serial port communication is required to configure the AR500 for operation. The easiest way to communicate is by using a PC with an RS232 communication port and a terminal emulation program that uses hexadecimal binary format. -

higher tetrad. When multi-byte values are transferred, the transmission begins with the lower byte. The following is the format of two ‘message’ data bursts for transmission of byte: DAT(7:0) Byte 0 Byte 1 DAT(3:0) DAT(7:4) 5.1.3 Answer "Answer’’ is data burst that can be transmitted by a ‘slave’ in the course of the session. -
Page 22: Data Stream
When working with the parameters, it should be noted that when the power is OFF, the parameter values are stored in nonvolatile FLASH- memory of the sensor. When power is ON, the parameter values are read out to RAM of the sensor. To retain these changes for the next power-up state, a special command for saving current parameter values in the FLASH-memory (04h) must be run. -
Page 23: Analog Output Operation
Analog Output Operation AR500 sensors can be ordered with either 4-20mA or 0–10 V analog outputs. The analog outputs use the same two wires. Please refer to Section 4.4 for connection details. The analog output is updated with each sample measured. The analog output will deliver a current which increases linearly from 4 mA (or 0 volts) at the range beginning point to 20 mA (10 volts) at the range end point. - Page 24 0Fh – High byte for the END of the analog output range. Default value is 4000h. Value range: 0 - 4000h. This code specifies a point within the sensor’s span Where: the analog output has a maximum value. AR500 User’s Manual LLL00xxxx –...

Page 27: Sampling Mode (02H Bit S)
Parameter 18h is the HIGH byte of the Zero Point and has values 0 - 4000h with default value 0. 8.5 Sampling Mode (02h bit S) The AR500 has two sampling modes, Time or Trigger Sampling. The factory default setting is Time Sampling. The sensor must be in Data Stream Mode. -
Page 28: Output Rate
taken into account in the case Where: small sampling period intervals are used. If the transmission time exceeds the sampling period, it is this time that will determine the data transmission rate. 8.6.1 Output Rate The sensor’s output rate (OR) depends on the selected Baud rate (BR) of serial interface and is calculated by the following formula: OR = 1 / (44/BR+1*10 ) Hz. -
Page 29: Results Averaging Mode (02H Bit M)
8.9 Results Averaging Mode (02h bit M) This parameter defines one of the two methods of averaging of measurement results implemented directly in the sensor: Averaging over a Number of Results or Time Averaging. The factory default setting is for Averaging over a Number of Results. -
Page 30: Demo And Configuration Software
9. Demo and Configuration Software The AR500-SP software is intended for making simple serial (or Ethernet, if ordered) connections to the AR500 for demonstration purposes and configuration of the many sensor parameters. It is also possible to archive measurement data to a file using this software. -
