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:

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.

LS 2106 Product Reference Guide

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.

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

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.

Enable/Disable Code 39 Full ASCII

To enable or disable Code 39 Full ASCII, scan the appropriate bar code below. When enabled, the ASCII character set assigns a code to letters, punctuation marks,

numerals, and most control keystrokes on the keyboard. The ﬁrst 32 codes are non-printable and are assigned to keyboard control characters such as

BACKSPACE and RETURN. The other 96 are called printable codes because all but SPACE and DELETE produce visible characters.

Code 39 Full ASCII interprets the bar code special character ($ + % /) preceding a Code 39 character and assigns an ASCII character value to the pair. For example, when Code 39 Full ASCII is enabled and a +B is scanned, it is interpreted as b, %J as ?, and $H emulates the keystroke BACKSPACE. Scanning ABC$M outputs the keystroke equivalent of ABC ENTER.

The scanner does not autodiscriminate between Code 39 and Code 39 Full ASCII.

Code 39 Buffering (Scan & Store)

When you select the scan and store option, all Code 39 symbols having a leading space as a ﬁrst character are temporarily buffered in the unit to be transmitted later. The leading space is not buffered.

Decode of a valid Code 39 symbol with no leading space causes transmission in sequence of all buffered data in a ﬁrst-in ﬁrst-out format, plus transmission of the “triggering” symbol. See the following pages for further details.

When the scan and transmit option is selected, decoded Code 39 symbols without leading spaces are transmitted without being stored in the buffer.

Scan and Store affects Code 39 decodes only . If you select scan and store, we recommend that you conﬁgure the scanner to decode Code 39 symbology only.

BUFFER CODE 39

(ENABLE)

DO NOT BUFFER CODE 39

(DISABLE)

While there is data in the transmission buffer, deleting Code 39 buffering capability via the parameter menu is not allowed. The buffer holds 200 bytes of information.

To allow disabling of Code 39 buffering, ﬁrst force the buffer transmission (see Transmit

Buffer) or clear the buffer . Both the CLEAR BUFFER and TRANSMIT BUFFER bar codes

are length 1. Be sure Code 39 length is set to include length 1.

4-31

LS 2106 Product Reference Guide

Buffer Data

To buffer data, Code 39 buffering must be enabled, and a symbol must be read with a space immediately following the start pattern.

t Unless symbol overﬂows the transmission buffer, the unit gives a lo/hi beep to

indicate successful decode and buffering. See Overﬁlling Transmission Buffer.

t Unit adds the message, excluding the leading space to the transmission buffer. t No transmission occurs.

Clear Transmission Buffer

To clear the transmission buffer, read a symbol which contains only a start character, a dash (minus), and a stop character.

Transmit Buffer

To transmit the buffer, read a symbol containing either the ﬁrst or second condition:

1. Only a start character, a plus (+), and a stop character.

s The unit signals that the transmission buffer has been sent (a lo/hi beep). s Unit sends the buffer. s Unit clears the buffer.

TRANSMIT BUFFER

2. A Code 39 bar code with leading character other than a space. s The unit signals a good decode and buffering of that decode has occurred by

giving a hi/lo beep.

s Unit transmits the buffer. s Unit signals that the buffer has been transmitted with a lo/hi beep.

Overﬁlling T ransmission Buffer

If the symbol just read results in an overﬂow of the transmission buffer:

t Unit indicates that the symbol has been rejected by issuing three long, high beeps.

s No transmission occurs. Data in buffer is not affected.

Attempt to Transmit an Empty Buffer

If the symbol just read was the transmit buffer symbol and the Code 39 buffer is empty:

t A short lo/hi/lo beep signals that the buffer is empty. t No transmission occurs. t The buffer remains empty.

Set Lengths for Interleaved 2 of 5

Lengths for I 2 of 5 may be set for any length, one or two discrete lengths, or lengths within a speciﬁc range. The length of a code refers to the number of characters (i.e., human readable characters) the code contains, and includes check digits.

One Discrete Length - This option allows you to decode only those codes containing a selected length. For example, if you select I 2 of 5 One Discrete Length, then scan 1, 4, the only I 2 of 5 symbols decoded are those containing 14 characters. Numeric bar codes begin on page 4-57. If you make an error or wish to change your selection, scan CANCEL on page 4-59.

Aperture The opening in an optical system deﬁned by a lens or bafﬂe that

establishes the ﬁeld of view.

ASCII American Standard Code for Information Interchange. A 7 bit-plus-

parity code representing 128 letters, numerals, punctuation marks, and control characters. It is a standard data transmission code in the U.S.

Autodiscrimination The ability of an interface controller to determine the code type of a

scanned bar code. After this determination is made, the information content can be decoded.

Bar The dark element in a printed bar code symbol. Bar Code Density The number of characters represented per unit of measurement

(e.g., characters per inch).

Bar Height The dimension of a bar measured perpendicular to the bar width. Bar Width Thickness of a bar measured from the edge closest to the symbol start

character to the trailing edge of the same bar.

Baud Rate A measure of the data ﬂow or number of signaling events occurring

per second. When one bit is the standard "event," this is a measure of bits per second (bps). For example, a baud rate of 50 means transmission of 50 bits of data per second.

Bit Binary digit. One bit is the basic unit of binary information. Generally,

eight consecutive bits compose one byte of data. The pattern of 0 and 1 values within the byte determines its meaning.

Glossary-1

LS 2106 Product Reference Guide

Byte On an addressable boundary, eight adjacent binary digits (0 and 1)

combined in a pattern to represent a speciﬁc character or numeric value. Bits are numbered from the right, 0 through 7, with bit 0 the low-order bit. One byte in memory can be used to store one ASCII character.

CDRH Center for Devices and Radiological Health. A federal agency

responsible for regulating laser product safety. This agency speciﬁes various laser operation classes based on power output during operation.

CDRH Class 1 This is the lowest power CDRH laser classiﬁcation. This class is

considered intrinsically safe, even if all laser output were directed into the eye's pupil. There are no special operating procedures for this class.

CDRH Class 2 No additional software mechanisms are needed to conform to this

limit. Laser operation in this class poses no danger for unintentional direct human exposure.

Character A pattern of bars and spaces which either directly represents data or

indicates a control function, such as a number, letter, punctuation mark, or communications control contained in a message.

Character Set Those characters available for encodation in a particular bar code

symbology.

Check Digit A digit used to verify a corr ect symbol decode. The scanner inserts the

decoded data into an arithmetic formula and checks that the resulting number matches the encoded check digit. Check digits are required for UPC but are optional for other symbologies. Using check digits decreases the chance of substitution errors when a symbol is decoded.

Codabar A discrete self-checking code with a character set consisting of digits

0 to 9 and six additional characters: ( - $ : / , +).

Code 128 A high density symbology which allows the controller to encode all

128 ASCII characters without adding extra symbol elements.

Code 3 of 9 (Code 39) A versatile and widely used alphanumeric bar code symbology with

a set of 43 character types, including all uppercase letters, numerals from 0 to 9, and 7 special characters (- . / + % $ and space). The code name is derived from the fact that 3 of 9 elements representing a character are wide, while the remaining 6 are narrow.

Code 93 An industrial symbology compatible with Code 39 but offering a full

character ASCII set and a higher coding density than Code 39.

Glossary-2

Glossary

Code Length Number of data characters in a bar code between the start and stop

characters, not including those characters.

Continuous Code A bar code or symbol in which all spaces within the symbol are parts

of characters. There are no intercharacter gaps in a continuous code. The absence of gaps allows for greater information density.

Dead Zone An area within a scanner's ﬁeld of view, in which specular reﬂection

may prevent a successful decode.

Decode To recognize a bar code symbology (e.g., UPC/EAN) and then

analyze the content of the speciﬁc bar code scanned.

Decode Algorithm A decoding scheme that converts pulse widths into data

representation of the letters or numbers encoded within a bar code symbol.

Depth of Field The range between minimum and maximum distances at which a

scanner can read a symbol with a certain minimum element width.

Discrete Code A bar code or symbol in which the spaces between characters

(intercharacter gaps) are not part of the code.

Discrete 2 of 5 A binary bar code symbology representing each character by a group

of ﬁve bars, two of which are wide. The location of wide bars in the group determines which character is encoded; spaces are insigniﬁcant. Only numeric characters (0 to 9) and START/STOP characters may be encoded.

EAN European Article Number. This European/International version of

the UPC provides its own coding format and symbology standards. Element dimensions are speciﬁed metrically. EAN is used primarily in retail.

Element Generic term for a bar or space. Encoded Area Total linear dimension occupied by all characters of a code pattern,

including start/stop characters and data.

Host Computer A computer that serves other terminals in a network, providing such

services as computation, database access, supervisory programs, and network control.

IEC International Electrotechnical Commission. This international agency

regulates laser safety by specifying various laser operation classes based on power output during operation.

Glossary-3

LS 2106 Product Reference Guide

IEC (825) Class 1 This is the lowest power IEC laser classiﬁcation. Conformity is

ensured through a software restriction of 120 seconds of laser operation within any 1000 second window and an automatic laser shutdown if the scanner's oscillating mirror fails.

Intercharacter Gap The space between two adjacent bar code characters in a discrete

code.

Interleaved Bar Code A bar code in which characters are paired together, using bars to

represent the ﬁrst character and the intervening spaces to represent the second.

Interleaved 2 of 5 A binary bar code symbology representing character pairs in groups

of ﬁve bars and ﬁve interleaved spaces. Interleaving provides for greater information density. The location of wide elements (bar/ spaces) within each group determines which characters are encoded. This continuous code type uses no intercharacter spaces. Only numeric (0 to 9) and START/STOP characters may be encoded.

Laser Diode A gallium-arsenide semiconductor type of laser connected to a power

The laser is an intense light source. Light from a laser is all the same frequency, unlike the output of an incandescent bulb. Laser light is typically coherent and has a high energy density.

source to generate a laser beam. This laser type is a compact source of coherent light.

LED Indicator A semiconductor diode (LED - Light Emitting Diode) used as an

indicator, often in digital displays. The semiconductor uses applied voltage to produce light of a certain frequency determined by the semiconductor's particular chemical composition.

Nominal The exact (or ideal) intended value for a speciﬁed parameter.

Nominal Size Standard size for a bar code symbol. Most UPC/EAN codes can be

Parameter A variable that can have different values assigned to it.

A condition which occurs when the data output of a reader or interface controller does not agree with the data encoded within a bar code symbol.

T olerances are speciﬁed as positive and negative deviations fr om this value.

Percent Decode The average probability that a single scan of a bar code would result

in a successful decode. In a well-designed bar code scanning system, that probability should approach near 100%.

Print Contrast Signal (PCS)

Programming Mode The state in which a scanner is conﬁgured for parameter values. See

Quiet Zone A clear space, containing no dark marks, which precedes the start

Reﬂectance Amount of light returned from an illuminated surface. Resolution The narrowest element dimension which can be distinguished by a

Scan Area Area intended to contain a symbol. Scanner An electronic device used to scan bar code symbols and produce a

Scanning Mode The scanner is energized, programmed, and ready to read a bar code.

Measurement of the contrast (brightness difference) between the bars and spaces of a symbol. A minimum PCS value is needed for a bar code symbol to be scannable. PCS = (RL - RD) / RL, where RL is the reﬂectance factor of the background and RD the reﬂectance factor of the dark bars.

particular reading device or printed with a particular device or method.

digitized pattern that corresponds to the bars and spaces of the symbol. Its three main components are:

1. Light source (laser or photoelectric cell) - illuminates a bar code.

2. Photodetector - registers the difference in reﬂected light (mor e light reﬂected from spaces).

3. Signal conditioning circuit - transforms optical detector output into a digitized bar pattern.

Scanning Sequence A method of programming or conﬁguring parameters for a bar code

reading system by scanning bar code menus.

Self-Checking Code A symbology that uses a checking algorithm to detect encoding err ors

within the characters of a bar code symbol.

Space The lighter element of a bar code formed by the background between

bars.

Specular Reﬂection The mirror-like reﬂection of light from a surface, which can “blind” a

scanner.

Start/Stop Character A pattern of bars and spaces that pr ovides the scanner with start and

stop reading instructions and scanning direction. The start and stop characters are normally to the left and right margins of a horizontal code.

Substrate A foundation material on which a substance or image is placed. Symbol A scannable unit that encodes data within the conventions of a certain

symbology , usually including start/stop characters, quiet zones, data characters, and check characters.

Symbol Aspect Ratio The ratio of symbol height to symbol width. Symbol Height The distance between the outside edges of the quiet zones of the ﬁrst

row and the last row.

Symbol Length Length of symbol measured from the beginning of the quiet zone

(margin) adjacent to the start character to the end of the quiet zone (margin) adjacent to a stop character.

Symbology The structural rules and conventions for representing data within a

particular bar code type (e.g. UPC/EAN, Code 39).

Tolerance Allowable deviation from the nominal bar or space width. UPC Universal Product Code. A relatively complex numeric symbology.

Each character consists of two bars and two spaces, each of which can be any of four widths. The standard symbology for retail food packages in the United States.

Visible Laser Diode (VLD)

Glossary-6

A solid state device which produces visible laser light. Laser light emitted from the diode has a wavelength of 670 to 680 nanometers.
