Speeder X1 and X2 Configuration and API Guide

1 INTRODUCTION TO THE FAST RANGEFINDERS
1.1 Introduction
This document presents Configuration and Application programming interface (API) for
Speeder X1 and X2 Laser Radars which are based on Noptel’s fast rangefinder
technology. Connections and hardware of the sensors is presented in ”
CM5 Technical
manual”
.
Speeder is designed for Speed measurement but it is also suitable for Distance
Measurement and Target Detection. Versatile utilization of sensors leads to diverse
Configuration and Parameterization. The document is intended as facilitate the work.
1.2 Communication protocol
Baud rates:
The sensors operate connected to the RS-232 or RS-422 port, using baud rates of 1200
to 921600 bd.
The bit stream of serial port consists of:
Data bits
8
Parity
None
Stop bit
1
Flow Control
None
The main commands of the sensor are described in this chapter. The default baud rate is
9600. If the baud rate is not known, the user can reset the baud rate to 9600 by sending
multiple <esc>’s to the serial port, while connecting power on to the sensor.
The ASCII command protocol is in the form:
<esc>[Device Number]<Command><Value1>,<Value2><cr>
Where
<esc>
ASCII code 27
[Device Number]
is an option, 1
–9 if two or more sensors are connected to a serial port,
Command
is a command according to the Chapter 1.3,
<Value1> and <Value2> are parameter No. and values in ASCII format (if needed), and
<cr>
is Carriage Return (ASCII code 13).
The controller must be in Configuration Mode (par. #1 = 0) when giving commands. The
character <esc> is used for returning the sensor to base state.
