Service Information

If you have a problem with your equipment, contact the Symbol Support Center. Before calling, have the model number , serial number, and several of your bar code symbols at hand.

Call the Support Center from a phone near the scanning equipment so that the service person can try to talk you through your problem. If the equipment is found to be working properly and the problem is symbol readability, the Support Center will request samples of your bar codes for analysis at our plant.

Setting Up the LS 2106

Introduction

The LS 2106 hand-held laser scanner offers excellent performance in retail and light industrial applications. Advanced ergonomic design ensures comfortable use for extended periods of time.

The LS 2100 Series hand-held scanner is based on the SE 1200 Series scan engine, mylar® scan element and the Visible Laser Diode (VLD). This state of the art technology gives the scanner a wider decode zone, greater depth of ﬁeld, and a visible scan beam. This model reads color bar codes and symbols printed on all substrates. See the 2-4.

LS 2106 - The LS 2106 scanner is a keyboard “wedge” interface which adds efﬁcient,

reliable bar code reading to your PS/2 or A T/XT terminal. Since entered scan data is

transmitted as keystrokes, no software changes to the host system are necessary . The

scanner contains on-board discrete keyboard wedge communications for connecting

to asynchronous terminals and host systems. It can also accommodate any of the

Synapse™ “Smart Cables” which allows you to connect to a wide variety of host

systems. Some installations require one cable; others require additional adapters

between the keyboard, the PC, and the y-cable.

All of the LS 2100 series scan automatically at the rate of 36 scans per second. For decode capability, see

“Smart Cables”, which allow you to connect to:

Wand Emulation terminals

IBM 4683/4, 4693/4 series of terminals

Switching Cables

Different cables are required for different hosts. To change the scanner cable:

1. Press the tab on the cable with a small screwdriver.

2. Pull the cable out of the receptacle on the bottom of the scanner.

3. Insert a new cable in the receptacle. Press the cable into the receptacle until you hear a click.

Scanning with the LS 2106

Introduction

This chapter covers the proper techniques for scanning bar codes and the decode zone for the LS 2106 scanner.

Scanning with the LS 2106

Before you can use the scanner , it should have already been installed and programmed. If not, refer to Chapter 4, need assistance, contact your local supplier or Symbol Techologies.

1. Before you use the scanner, make sure all cable connections are secure.

2. Make sure the bar code is in the correct scanning range. Aim and press the trigger; the scan beam lights and an orange light illuminates at the rear of the scanner. The scanner has read the symbol when:

You hear a beep.

The orange light turns green.

The laser turns off.

Figure 2-1. Holding the Scanner

Aiming the Scanner

Hold the scanner at an angle. Do not hold the scanner directly over the bar code. Laser light reﬂecting directly back into the scanner from the bar code is known as specular reﬂection. This strong light can “blind” the scanner and make decoding difﬁcult. The area where specular reﬂection occurs is known as a “dead zone”.

You can tilt the scanner up to 55° forward or back and achieve a successful decode. Simple practice quickly shows what tolerances to work within.

2-2

Scanning with the LS 2106

t Scan the Entire Symbol

s The scan beam must cross every bar and space on the symbol (as in the left bar

code below).

s The larger the symbol, the farther away you should hold the scanner. s Hold the scanner closer for symbols with bars that are close together.

What Does The Beep Mean?

When you hear 1 beep (short high tone) it means data has been decoded successfully. If any other beeps are heard, contact the technical person in charge of scanning.

When the symbol has been successfully decoded, you will hear a short, high-tone beep, and the green decode LED will light.

For more speciﬁc information on the meanings of the various beeper sounds, refer to Beeper

Indications on page 3-7.

Maintenance and Speciﬁcations

Introduction

This chapter covers the appropriate methods for maintaining and the technical speciﬁcations for the scanner.

Maintenance

Cleaning the exit window is the only maintenance required. A dirty window may affect scanning accuracy.

t Do not allow any abrasive material to touch the window. t Remove any dirt particles with a damp cloth. t Wipe the window using a tissue moistened with ammonia/water. t Do not spray water or other cleaning liquids directly into the window. t Do not remove the nose of the scanner.

Troubleshooting

If, after following the operating instructions, the scanner does not work:

t Check the system power. t Make sure the controller is programmed to decode bar codes of the symbology you

are scanning.

t Check for loose cable connections.

3-1

LS 2106 Product Reference Guide

t Make sure the symbol is not defaced. t Try scanning test symbols of the same code type.

If after performing these checks the symbol still does not scan, contact your distributor or call the Symbol Support Center. See page x for the telephone number.

Introduction

The LS 2106 is shipped with the settings shown in the Default Parameters beginning on page

4-2. These default values are stored in non-volatile memory and are preserved even when the

scanner is powered down. You can change these default values by scanning the appropriate bar codes included in this manual. These new values replace the standard default values in memory . The default parameter values can be recalled by scanning the SET ALL DEF AUL TS bar code on page 4-7.

The scanner automatically identiﬁes the host type on power-up. It makes this determination provided the host is powered-up before the scanner is attached to it. The following table lists the defaults for all parameters. If you wish to change any option, scan the appropriate bar code(s).
