Chapter 2 Scanning
Introduction
This chapter covers the techniques involved in scanning bar codes. Included are
specific instructions on how to hold the scanner at the appropriate angle to ensure an
accurate decode.
2-1
LS 1000 Product Reference Guide: Chapter 2, Scanning
Ready , T est, Scan
1. Ready
Make sure all connections are secure.
2. Test
Aim the scanner away from you and press the trigger. When you press the
trigger, the scanning beam is energized. On the LS 1000, the length of time the
beam remains on depends on the controller or terminal into which it is
plugged. On the LS 1004, the scanner is energized for approximately 1 second
(default).
3. Scan
Make sure the symbol you want to scan is within the scanning range. See the
100x Decode Zone
Aim and press the trigger . On the LS 1000, the scan beam and SCAN LED lights for
3.5 seconds, or until a successful decode occurs. On the LS 1004, if you use the
scanner in default Low Power operating mode, the DECODE LED remains on until
power down (maximum of 1 second). If the unit is programmed for Continuous
power operating mode, the DECODE LED stays on until the next trigger pull.

The scanner has read the symbol when:
• You hear a short, high tone beep (if the beeper is enabled).
• The DECODE LED lights.

LS 1000 Product Reference Guide: Chapter 2, Scanning
Aiming
Scan the Entire Symbol
• Your scan beam must cross every bar and space on the symbol.
• The larger the symbol, the farther away you should hold the scanner.
• Hold the scanner closer for symbols with bars that are close together.
• A short, high tone beep indicates a good decode.

Hold 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 65° forward or back and achieve a successful decode.
Simple practice quickly shows what tolerances to work within.

Battery Box Operation
When using the LS 1000 Series with a battery box, you can use either an alkaline battery
(recommended), or a nickel-cadmium rechargeable battery. Low power is signalled by
4 short, high-tone beeps, coupled with scanning interruptions. If this occurs, change or
recharge the battery as soon as possible. For battery box operation:
1. Insert a 9-volt battery into the battery box.
2. Plug the scanner’s 9-pin connector at the end of the coil cord into the end of the
battery box.
3. An output cable from the battery box connects the LS 1000 Series to the host device.
Connect one end of this cable to the battery box and the other to the appropriate
port on the host device.
Note:

Scanning Sequence
A scanning sequence establishes a value for one parameter type. During a scanning
sequence, bar codes are scanned to select a parameter. All bar codes necessary for
programming the scanner are provided in the Appendix section of this manual.
Scanning Sequence Example
In this example, assume you want to program the scanner for all default settings except
for two parameters, Appendix and Appendix .
Since you want to keep the majority of the default settings, scan the Appendix bar
code. The default for DECODE UPC ONLY is DISABLED, but in this example, you
need it enabled. To do this, scan the DECODE UPC ONLY ENABLE bar code. You’ll
hear hi/lo/hi/low warble. The warble sound indicates that the scanner has been
successfully programmed for the selected parameter. Other beeper indications are
listed in Chapter 3.
The default for INTERCHARACTER DELAY is 0 msec, but you need it set to 2 msec.
To program the scanner for a 2msec intercharacter delay, scan the bar codes listed
below. This sequence includes a two-digit entry; single-digit entries require a leading
zero.
You’ll hear...
1. Scan INTERCHARACTER DELAY Short high tone
2. Scan 0 Short high tone
3. Scan 2 Hi/Lo/Hi/Lo warble
Errors While Scanning
Don’t worry if you make an error during a scanning sequence. If you’re scanning a
multi-step sequence, scanning CANCEL removes you from that sequence so that you
can start again.
Otherwise, simply scan the single correct bar code for the desired parameter.

UPC/EAN Security Level
The scanner offset four levels of decode security for UPC/EAN bar codes. Increasing
levels of security are provided for decreasing levels of bar code quality. There is an
inverse relationship between security and scanner aggressiveness, so be sure to choose
only that level of security necessary for any given application.
Security Level 0 - This is the default setting which allows the scanner to operate in its
most aggressive state, while providing sufficient security in decoding in spec UPC/
EAN bar codes.
Security Level 1 - As bar code quality levels diminish, certain characters become prone
to mis-decodes before others (i.e., 1, 2, 7, 8). If you are experiencing mis-decodes of
poorly printed bar codes, and the mis-decodes are limited to these characters, select
this security level.
Security Level 2 - If you are experiencing mis-decodes on poorly printed bar codes, and
the mis-decodes are not limited to characters 1, 2, 7 and 8, select this security level.

Hardware handshaking allows you to check the readiness of the receiving device
before data is transmitted. If the receiving device is periodically occupied with other
tasks, hardware handshaking is needed to prevent loss of transmitted data.

Software Handshaking
This parameter offers control of the data transmission process in addition to, or instead
of, that offered by hardware handshaking. These options may be combined; for
example, ACK/NAK with ENQ.
• No software handshaking
None
• ACK/NAK only
The ACK/NAK option checks the success or failure of transmission. The scanner
expects one of the following host responses after a data transmission:
<ACK> acknowledges a valid and successful transmission.
<NAK> indicates a problem with the transmission.
Whenever a NAK is received, the unit retransmits the same data and awaits an
ACK/NAK response. After three unsuccessful attempts to transmit the same
data, the scanner aborts any further communication attempts of that message.
ACK/NAK
• ENQ ONLY
The ENQ option needs the host to request data before it is transmitted to the host.
This ensures that data transmission occurs only when the host is ready to receive.
When you select the wait for ENQ option, the scanner waits for an ENQ from the
host before it transmits data; otherwise, the unit transmits data without waiting
for an ENQ character from the host. W ith ENQ enabled, the scanner must receive
an ENQ from the host within a 2-second period after the last activity, or a

ASCII - American Standard Code for Information Interchange. A 7 bit code
representing 128 letters, numerals, punctuation marks, and control
characters. It is a standard data transmission code in the U.S.
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.
BOOKLAND EAN - A specially-formatted European Article Numbering
symbol with 13 characters (EAN-13), the first 3 of which are “978”.
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 thr ough 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.
CHECK DIGIT - A digit used to verify a correct 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.
5-1
LS 1000 Series Product Reference Guide
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.
CONTINUOUS SYMBOLOGY - A bar code or symbol in which all spaces
within the symbol are parts of characters. There are no inter character gaps in a
continuous code. The absence of gaps allows for greater information density.
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.
DISCRETE SYMBOLOGY - 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 r epresenting 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.
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.
5-2
Glossary
IEC CLASS I (IEC 825 Class I) - This is the lowest power IEC laser
classification. Conformity is ensured through a software restriction of 25
seconds of laser operation within any 100 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 bar code.
INTERLEAVED BAR CODE - A bar code in which characters are paired
together , using bars to repr esents the first character and the intervening spaces
to represent the second.
INTERLEAVED 2 OF 5 - A binary bar code symbology repr esenting 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 - An acronym for Light Amplification by Stimulated Emission of
Radiation. 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.
LASER DIODE - A semiconductor type of laser connected to a power source
to generate a laser beam. This laser type is a compact source of coherent light.
PARAMETER - A variable that can have different values assigned to it.
PROGRAMMING MODE - The state in which a scanner is configured for
parameter values. See SCANNING MODE.
QUIET ZONE - A clear space, containing no dark marks, which precedes the
start character of a bar code symbol and follows the stop character.
REDUNDANCY - A decoding method which requires a bar code be
recognized redundantly on a number of sweeps of the scan beam before a
decode is declared. While slowing the time-to-decode, redundancy can help
lower the possibility of a mis-decode of poorly printed symbols.

LS 1000 Series Product Reference Guide
SCANNER - An electronic device used to scan bar code symbols and pr oduce
a 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 (more light
reflected from spaces).
3. Signal conditioning circuit - transforms optical detector output into a
digitized bar pattern.
SCANNING MODE - The scanner is energized, programmed, and ready to
read a bar code.
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 errors within the characters of a bar code symbol.
START/STOP CHARACTER - A pattern of bars and spaces that provides 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.
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.
SYMBOLOGY - The structural rules and conventions for representing data
within a particular bar code type (e.g. UPC/EAN, Code 39).
UPC - Universal Product Code. A r elatively 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.
