Section 1

Introduction and Getting Started

Product Overview

The LPN5627 and LPR5627 (Raster) Fixed Position Scanners are miniature, 500 scan per second, laser

bar code readers designed to be easily incorporated into host equipment. The high scan speed and small

physical size make the scanner easy to integrate into any hardware design. Durability and reliability are

assured.

Advanced microprocessor technology coupled with Opticon’s proven decoding algorithms result in high

speed operation with superior accuracy. The scanners are fully programmable allowing the user to

customize parameters including changing communication settings, selecting symbologies, adding prefixes

and appending suffixes. Programmable settings can be downloaded from the host CPU or computer

directly to the scanner.

The scanners are encased in compact, rugged metal enclosures. The compact size permits installation in

the tightest areas allowing great flexibility in mounting and positioning the scanner for optimum

performance.

Quick Start-Up Procedure

This section is for those who wish to start using the scanner before reading the complete manual. Only a

few steps are needed to make the scanner operable.

A Developers Evaluation and Test board is available to allow rapid installation of the scanner

Connect the scanner min-DIN connector to the board

Using the DB9 extension cable, connect the board to a DB9 serial port, such as COM 1 on you PC.

Be sure your PC or host device is running an application such as HyperTerminal that will accept

serial input.

The default communications parameters of the scanner are 9600 baud, 1 Start/Stop Bit, 8 Data bits,

No Parity, No Handshaking, No Flow Control) See Users Manual for details on establishing or

changing communications parameters.

Plug the 5V DC power supply into the jack on the board

There is a trigger test button on the scanner. There is a trigger button on the Evaluation and Test

board as well.

That’s it. Your PC and the scanner should now communicate.

To verify that the scanner and the PC are communicating properly, send the following command from

your PC keyboard to activate the scanner’s buzzer.

Send the command: <Escape> V5 <Carriage Return>

Note: Be sure to use capital letters, e.g. “V5”, not “v5”.

The buzzer should sound, indicating that good communications have been established

To test the scanner, press the trigger test button on the scanner itself or on the evaluation board. A red

laser light will be visible. Do not stare into the laser light.
