AR100 Operation Manual
1
1. Introduction
This section is a guide to getting started with the AR100 and this manual. The
AR100 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 AR100 sensor configurations that can be ordered from Acuity.
Your specific AR100 model may not have all interfaces and functions described in
this manual.
The recommended order for reading the manual is:
• General Overview – Gives a brief understanding of the sensor operation.
• Operating Guidelines – Provides a few important safety tips.
• Definition of Terms – An aid for proper communication.
• Quick Start Instructions – This should provide the information necessary to
connect the sensor and verify its operation, either with a serial terminal
program at 9600 baud, or by connecting the current loop or Alarm Output
interface.
• General Description – Gives important laser, operation, mechanical, and
mounting information.
• Installation and Checkout – Tailor the application. Use the other chapters
for reference:
Signal and Power Interface – how to hook everything up
Serial Interface Operation – modes, formats, bias
Analog Output Operation – current loop, voltage, scaling
Alarm Output Operation – alarm settings
Performance Optimization – Sample Rate, Background Elimination,
Exposure control
AR100 Command Set – explains all commands for customizing the
application
1.1 General Overview
The AR100 is a triangulation sensor that measures distance using a laser beam,
a camera, and a microprocessor. A variety of models are specified, each to
allow a different measurement range, communications interface, and laser
diode option. Models vary in range from 10 to 500 mm. Interface options
include RS232, RS485, 4-20mA, and 0-10V.
The accuracy is generally specified with a linearity of about +/- 0.05% of the
range.
A variety of configuration settings can be selected via the serial port. The
complete list of settings is found in the AR100 Command Set chapter and each
setting is discussed in detail in a specific operation chapter.
The Sample Rate can be specified and the sensor has capability above 9400
samples per second. Several other configurable parameters enhance the
performance. Sampling may be turned on and off. It can even be triggered
using an input signal wire or a serial command.
