Preface
This manual is a reference guide for using the AdaptaScan Software.
It describes features and procedures for configuring the operation of
the AdaptaScan Bar Code Reader.
Because this is a reference manual it covers all the features of the
AdaptaScan Software. You may not use or need to use all the
features, so use the manual as needed.
If you’re just getting started, make sure you work through the
Getting Started chapter. It takes you through all the steps
required to get the Reader scanning and decoding bar code
symbols.
What is AdaptaScan?
The AdaptaScan Bar Code Reader includes a scanner and decoder in
a single compact package. The Reader is configured using a
Microsoft Windows 95 or Windows NT based package that lets
you create, store and download applications. To simplify application
design, the AdaptaScan software uses menus, dialog boxes and tools
which are standard in Windows.
Applications are transferred between your computer and an
AdaptaScan Reader using a communication cable.
Intended Audience
This manual is written for the individual responsible for designing
bar code applications. We assume you are familiar with bar code
terminology. A glossary is provided at the end of this manual if you
are not familiar with a word or acronym.
Because AdaptaScan software runs in Microsoft Windows, you
should know how to use a mouse, choose commands, and work with
Windows and dialog boxes. To learn basic windows techniques, read
the User’s Guide that came with your Microsoft Windows package.
Software Package

Connection
When displayed, indicates a connection was made to the device:
• Yellow (default) indicates that the AdaptaScan software does not
have the information required to determine whether the device’s
configuration matches the configuration in the software database.
• Green appears after a Compare operation (see page 3–4) was
performed and the configuration of the on-line device matches the
database configuration.
• Red appears after a Compare operation (see page 3–4) was
performed and the configuration of the on-line device does not
match the database configuration.
Database
When displayed, indicates that a database configuration exists for the
Reader. The color indications are the same as for the Connection
icon (see descriptions above) except the database icon will remain

Information Lines
There are two areas on the project window that provide information
about a highlighted Reader configuration.
Connections per Reader / Description Field
Version Number / Compare Status
Connections Per Reader / Description
The total number of connections is displayed on the project dialog
along with a device description. The description displayed is entered
on the Device dialog description field.
Each Reader has a minimum of 7 and a maximum of 64 connections.
A connection is an AdaptaScan object that moves data both
internally and between Readers. For example, when Package Detect
is specified as the decode trigger, a connection moves data from the
package detect input to the decoder. If the Package Detect is from
another Reader, each of the Readers use the connection object.
Important: You will not be allowed to download a configuration
with more than 64 connections in a Reader. A warning message is
displayed. However, you can still read old databases with more than
64 connections. You will need to reduce the number of items that
use connections before downloading the configuration. Some items
that use connections are match fields, inputs and outputs.
Version Number / Compare Status
The first line shows the firmware version number of the Reader. The
second line shows the compare status in a text format and matches
the status shown by the connection and database status icons (see
previous page).

•
•
projects
Reader configurations
match functions
message fields
labels
symbols (can’t be copied)
The cut, copy, and paste icons and menu selections will only be
available where they can be used. Otherwise the icons will appear
grayed out.
Important: Cutting or copying and then pasting a Reader
configuration is different from importing/exporting Reader
configurations.
When an individual Reader configuration is pasted into a project,
only the original Reader’s configuration dialog boxes are copied and
recreated in the new project. Connections to and from the original
configuration are not recreated using Paste. Paste is useful when you
need to make a configuration similar to an existing configuration in
the currently open project or another project.
When you need to make an exact copy of a configuration, copy and
paste the entire project in the AdaptaScan database dialog or use the
import/export functions (see next page).

Going On-Line
The Go On-Line command establishes communications between the
AdaptaScan software and DeviceNet network using the
communication channel specified on the Preferences dialog (see
page 2–18).
To go on-line with AdaptaScan software:
Go On-Line
1. Click the Go On-Line icon or select Go On-Line from the
Communications menu.
The project window will display the devices on the network along
with their catalog number and address.
Note: The Query dialog may be displayed when you go on-line
(depending on your preference settings). Refer to page 2–19.
Note: If you are connected to the DeviceNet network using the
Reader configuration cable, only AdaptaScan Readers on the
network are identified and displayed. When connecting using a
DeviceNet communications card and driver software on your

History
Scanner metrics are useful during:
• Initial Setup for making minor adjustments to the scan beam on
the Scanner dialog.
• Normal operation to identify small decreases in performance.
For example, if the number of reads drops significantly, label
quality may have degraded or the scan window may require
cleaning.
Publication 2755-838
3–8
Margin
The scanner metric for margin is a measure of how clearly
distinguishable the different element sizes (bars and spaces) are in a
symbol. Margin is calculated every time a symbol is decoded. The
margin result is the tolerance remaining before the AdaptaScan can
no longer differentiate between wide and narrow elements.
Several factors affect the margin, including how well the
AdaptaScan is focused and the quality of the symbol. Assuming that
the AdaptaScan is properly focused, margin can be used for an
indication of trends in label quality. This is especially true for ink jet
symbols on cardboard cartons where low margins can occur because
of increasing ink spread.
Margin values may be returned in a host message (see page 10–2) or
used to trigger an output if the margin value falls below a user
defined level (see page 7–8).

Above Conveyor
If a linear scanning Reader is aligned parallel with the long axis of
a picket fence label, the same strip of label is scanned repeatedly.
Because of this, picket fence applications usually use a raster
scan.
Publication 2755-838
When the labels pass the scanner in a step ladder orientation, a linear scan is preferred. The beam scans the label as
it passes. The number of scans per label depends on the
label size, scan rate, and the conveyor speed.

Scan Adjustments
Online adjustments can affect the width and location of the scan
beam. Use these adjustments to make minor changes to an
application, not to compensate for improper installation.

Manual Focus
Manual adjustment of the read range is available in increments of 10
units (0 to 255 units) using the spinner controls or a value can be
typed in. Manual focus provides a trial and error process for finding
the best performance for a given application.
Autofocus
This feature automatically adjusts the scan beam focal distance for
the best margin for the symbol appearing at a fixed position. When
focus is initiated, the Reader continuously adjusts the focal distance
as a symbol is scanned (from minimum to maximum). The Reader
displays and records the margin at each focal length. The focus is set
at the point two-thirds of the way between the minimum and
maximum acceptable focus range units.

When defining a label setup:
• Enable only the symbologies the Reader is expected to scan to
increase the Reader’s response rate.
• Define as many parameters as you can for each label and
symbology to prevent the possibility of a misread.
• You can define label setups at any time (before or after other
Reader settings). However, label setups are assigned to a Reader
using the Decoder dialogs. It may be easier to create the label
setups prior to defining the operation of the decoder.
• For initial setup use the default settings when possible. When a
configuration is working, change decoder settings one at a time
while verifying the operation of the Reader (see Chapter 13).
6–2
What is a Label?
A label usually contains human readable text and one or more bar
code symbols that appear within the Reader scan area on a package.
Each bar code symbol may have different characteristics such as
symbology, prefixes, lengths, or check characters. The bar code
symbols must be oriented in the same direction if read by a single
scanner.
Below is an example of a typical label.
PART NO. (P)
QUANTITY (Q)
SUPPLIER (V)

By defining the expected content of a label, you can reduce the
possibility of a misread and increase the read rate. AdaptaScan
software can store and exchange label setups between Readers,
allowing you to create a library of label configurations.
Publication 2755-838

2.
3.
4.
5.
6.
Start and Stop codes are not included in the checksum.
Sum of even position digits is multiplied (weighted) by 3.
Sum of odd position digits is multiplied (weighted) by 1.
Odd and even weighted results are added together.
Divide the sum of the odd and even weighted results by 10.
Subtract the remainder of the division from 10 to obtain the checksum.
For example, the following code is decoded, the most significant
digit (digit #1) is to the left. The least significant digit is to the right
and is an even position digit.
Code = 8 6 1 3 2 5 1 8
Sum of 3 (sum even digits) + (sum odd digits) = 3 (6 + 3 + 5 + 8) + (8 + 1 + 2 + 1) = 78
Sum/10 = 78/10 = 7 with Remainder = 8

When configuring the Reader’s decode functions:
• Enable only the bar code symbologies the Reader will scan to
increase decode speed and reduce misreads.
• During initial setup, use the Self-Triggered decode option and
specify an Inter-Symbol No-Read Count. The Reader will
continuously attempt to decode data.
• To prevent misreads, trigger decoding only when a bar code label
is within the scan area of the Reader.
Decoding Functions
The Decoder dialogs define:
• When the Reader decodes bar code symbols from the scanner.
• What bar code symbologies are decoded.
• Minimum performance level before an alarm occurs.
7–2
Valid Symbologies
The Reader can be configured to decode the following symbologies:
Interleaved 2 of 5
Code 39
Discrete 2 of 5
UPC-A
UPC-E
USPS 2 of 5
EAN-8
EAN-13
Code 128
Pharma Code
Codabar
Code 93
Each of the symbologies has properties you can set up such as guard
bars, check characters and supplements.
Guard Bar
Guard Bar
Supplemental Digits
Publication 2755-838
7–3
When Decoding Occurs
The Decoder dialog settings determine when the Reader starts and
stops decoding. The trigger source may be from or on the Reader
you are configuring or another Reader on the same network (when
using DeviceNet peer-to-peer communications). You can use the
same package trigger for multiple Readers on a DeviceNet
peer-to-peer network or you can “chain triggers” where one Reader
is a trigger source for another Reader. Once triggered, the Reader
attempts to decode symbols until a trigger off is received.
Trigger inputs include: Self-Triggered, Package Detect, Discrete
Input, Timer, ASCII Command, Input Timer, or DeviceNet Inputs.
You can also select bracketed indirect trigger sources defined for
other functions such as [Match Table], [Package], [Message].
Note: [Match Table], [Package] or [Message] do not appear as
options unless a trigger has been defined for the match table,
package or message functions.
Self-Triggered Source
The Reader continuously attempts to decode data.
Package Detect Trigger Source
The Reader decodes data only after receiving a trigger from the
package detect sensor attached to the Reader.
Photo-Electric
Package Detector
Publication 2755-838
7–4
Discrete Input Trigger Source
The Reader decodes data only after receiving a trigger from a
discrete input (located in the wiring base).
Reader
I/O Modules
Wiring Base
Timer Trigger Source
The Reader decodes data only when the internal timer is On. The
timer can be configured On or Off for independent periods of time.
Internal Timer
ASCII Command Trigger Source
Data is only decoded after an ASCII Trigger On command is
received. The Reader decodes data until a Trigger Off command is
received, a valid package is decoded or the timer times out.
ASCII Host Command
Publication 2755-838
7–5
Input Timer
Timer which is triggered by another source. Typically used to
coordinate multiple Readers scanning the same package.
DeviceNet Input
Up to 7 discrete DeviceNet inputs trigger decoding. Refer to
Configuring DeviceNet Inputs on page 9–15.
[Package]
The same trigger configured for package is also used to trigger
decoding. See page 11–13.
[Message]
The same trigger configured for messages is also used to trigger
decoding. See page 10–5.
[Match Table]
The same trigger configured for match table is also used to trigger
decoding. See page 11–8.
[Decoder]
The same trigger configured for decoding on another Reader is also
used to trigger decoding on the current Reader.
Capture Count
The capture count specifies the number of consecutive identical valid
decodes before a valid read occurs.
Scan 1
ABC
If Capture Count is 3 or less, Scan is Valid
Scan 2
ABC
If Capture Count is 4 or more Scan is not Valid
Scan 3
ABC
Use higher capture counts to reduce misreads. Symbologies that are
not self-checking (do not use start and stop characters or check
characters) are more susceptible to misreads.
Setting the capture count too high may result in excessive no-reads,
particularly when the number of scans crossing the label during a
trigger period is low (5-10). Set the capture count to a value no
greater than half the number of scans crossing the label during a
single trigger period.

Communication Ports
Terminal block connections in the wiring base provide all power,
I/O, and communication links to a Reader. The RS-422/RS-485 or
RS-232 port may be used at the same time as the DeviceNet link.
DeviceNet
Supports multiple Readers and allows them to communicate with
other devices on the network. The DeviceNet cable consist of four
wires (2 power and 2 communications) and a shield connected to the
Reader wiring base.
RS-422 / RS-485 Port
An RS-422 / RS-485 port allows multidrop communications with a
single device or network such as a SLC 500 DH-485 network.
RS-232 Port
Provides point-to-point communications with a device having an
RS-232 port such as a PLC-5 Channel 0 port configured for RS-232.
Note: The Configuration Port Connector on the Reader is used to
download configurations, not the RS-232 connection.
Protocols
The RS-485/RS-422 and RS-232 serial ports support these protocols.
Terminal
Use dumb terminal (ASCII) protocol to communicate with a variety
of devices. This is the least secure of the protocols.
DF1
Use DF1 protocol to communicate with devices such as a PLC-5 that
also supports DF1 protocol. DF1 protocol provides error checking
capabilities.
DH-485
Use DH485 protocol to communicate with DH485 devices such as
an SLC 500 DH485 network or point-to-point link.

Types of Outputs
Each Reader can accept two I/O modules. When an output module
is installed, it can be controlled by the Reader configuration or any
other Reader on the same network.
Discrete Output
You can install two discrete output modules in the Reader’s wiring
base. These modules are available with a variety of voltage and
current ratings (refer to the AdaptaScan Bar Code Reader user
manual). Assign discrete outputs either a normally open or normally
closed state (to determine when output is energized).

Discrete Input
You can install two discrete input modules in the Reader’s wiring
base. These modules are available with a variety of voltage and
current ratings (refer to the AdaptaScan user manual). You can
configure discrete inputs to be ON when the input is either a high or
low state. In addition, inputs can be assigned a delay, debounce
filter, and have a cyclic operation when ON. An input can be used
by any Reader on the same network.
Positions for
2 I/O Modules

DeviceNet I/O
DeviceNet Peer-to-Peer Communications
Peer-to-peer communications are supported between Readers.
You can easily transfer data, inputs, outputs, triggers and other data
between Readers by selecting the other Readers from the
configuration dialogs. However, DeviceNet peer-to-peer
communication is only between Readers. The Reader does not
support peer-to-peer communication with other types of DeviceNet
devices. To communicate with other DeviceNet devices, you must
use DeviceNet master-slave communications.
Important: The maximum number of Readers that can be
connected on DeviceNet peer-to-peer network is 32.
Each DeviceNet network must be all peer-to-peer or all master-slave
communications. You cannot mix peer-to-peer and master/slave
communications on the same network. Do not use AdaptaScan
DH-485 master-slave mode simultaneously with DeviceNet
communications (peer-to-peer or master-slave).
DeviceNet Master-Slave Communications
Connect the AdaptaScan Reader to other DeviceNet devices through
either a PLC (Catalog No. 1771-SDN) or SLC (Catalog No.
1747-SDN) DeviceNet scanner. The AdaptaScan DeviceNet slave
supports up to 7 discrete inputs, 15 discrete outputs, and bar code
messages. The AdaptaScan operates as a slave device to the
DeviceNet scanner.

DeviceNet Master-Slave Communications
The AdaptaScan Reader connects to other DeviceNet slave devices
through either a PLC (Catalog No. 1771-SDN) or SLC (Catalog No.
1747-SDN) DeviceNet Scanner. The AdaptaScan operates as a slave
device to the DeviceNet scanner.
Message Formatting
Bar code message data sent to an SDN (DeviceNet) scanner is
formatted the same as messages sent through the serial port. Note
the following when formatting messages:
• If a replacement string is longer than the length specified in the
SDN scanner addressing, the message is truncated.
• If a replacement message is shorter than the length specified in
the SDN scanner addressing, the message is padded with the
specified fill character.
• If a pass/fail replacement string is longer than the length specified
in the SDN scanner addressing, the least significant bytes are
truncated.
Note: You must select DeviceNet option as the message destination
on the Message Format dialog.

➀ Bytes #0 and #1 (word 1) are reserved for Discrete I/O. See Page 9–14.
➁ Poll Rx Size = 4 + (# of Characters in string).
Message data is addressed and sent to other DeviceNet devices
through a DeviceNet scanner (Catalog No. 1771-SDN or
1747-SDN). To configure the scanner, you will need to provide the
size of the message data (see page 10–11), the beginning byte and bit
number of the message and the destination of the message data.
Message Flow Control (Handshaking)
DeviceNet Input #8 and Output #16 control the transmission of bar
code messages when using DeviceNet master-slave. Refer to
DeviceNet I/O in Chapter 9. Message flow control (handshaking)
lets the controller know that data is available and keeps the Reader
from sending out messages faster than they can be received. Your
controller logic program must initiate transfers of the message data
and set the DeviceNet Input #8 (Send Next Data) for message flow
control.
New Data
Is indicated by changing the state of Discrete Output #16 of the
DeviceNet I/O. A change of state (0$1) indicates that message data
is new.
Send Next Data
By changing the state of Discrete Input #8 of the DeviceNet I/O, the
PLC/SLC program control indicates the controller is ready to receive
the next message.
Note: The Application Guide (Publication 2755-6.8) included with
this manual contains an application note for using DeviceNet Master
/ Slave communications.
Publication 2755-838
10–14
Flow Control Example
The following shows how DeviceNet Input #8 and Output #16
control the transmission of messages. Output #16 is changed by the
Reader and Input #8 is changed by the controller.

Note: You can disable handshaking by deselecting the handshake
checkbox (see page 10–11). With handshaking disabled, it may be
possible to miss data if the Reader decodes data too fast for the
controller. In addition, identical data may not be read unless data
that changes such as package count is added to the message sent by
the Reader.

Using Pass-Through to
DeviceNet
The Serial Port dialog (page 8–5) contains a check box for Enable
Pass-Through to DeviceNet. With this box selected, data from the
serial port is passed through to a DeviceNet master-slave network.

DeviceNet Devices
To connect a device such as a decoded hand-held scanner, you will
need to create a custom cable. The AdpataScan Reader user manual
(Publication 2755-837) shows the AdaptaScan serial port
connections.
In the above example, the scanner data is input directly into the
AdaptaScan RS-232 serial port. The AdaptaScan reader outputs the
data to its DeviceNet port. To the rest of the DeviceNet network it
appears that the data is coming directly from the reader.
Note: If the serial port receives more characters than the controller
is configured to accept, 0s will appear in the data field. The 0s
indicate that the file size is being exceeded.

What is a Match Table?
A match table contains bar code data and/or metacharacters entered
by an operator. The Reader compares the match table entries with
the decoded bar code data. When matches are found, the Reader
determines whether or not a package has been read or activates
discrete output(s). A Reader match table may contain up to 128
match entries.
For Example, assume the following match table entries and package definitions.
➀

Reader 2 scans a label on the same package with a content of
123456 and 245678 which corresponds with the match table
definition for package 2.
➂
Reader 2 turns on a discrete output of Reader 1 as a result of
the match. The discrete output of Reader 1 sets a diverter to
route the package to its proper location.
Reader 1

Match Table Applications
Verify Labels
When verifying a label, the Reader compares the decoded data with
the expected label content entered in a match table.
Decoded Data (5/95) = Match Table (5/95)
Label Verified
Reader
Sort Products
When sorting products, the Reader compares decoded data with
match code entries. Each match table entry is linked to a different
output. When a package is read, the match table result turns on the
corresponding output.
Reader

Match Rules
Instead of entering the exact bar code data in a match table, you can
enter a rule (using metacharacters) to define a category of symbols.
For example, a rule that can match any symbol that begins with 231
and ends in 09.
All Match Rule: 231 . . . 09
See Appendix C for details on metacharacters.
Publication 2755-838
11–4
Defining a Package
The Reader determines when a package is read by matching the
decoded bar code symbols with symbols entered in a match table.
A valid package is decoded when all of the decoded symbols
correspond with the specified match table entries for the package.

Match Entry
Reader decodes two symbols ➀ on the package.
Two Match Entry ➁ functions are defined, one for each value.
The Match Table ➂ defines a Package as two match entries.
Decoded bar code symbols ➀ match the match table package definition ➂ resulting
in a valid package ➃.
An output module can be triggered whenever a match occurs or a
package is decoded. This allows you to design sorting and label
verification functions. In addition, the Reader has both match entry
and package counters for tracking the number of symbols or
packages read.
Publication 2755-838

Using Auto-Load
Auto-Load allows you to enter a Match Entry data string by scanning
the desired bar code label. Usually, the Auto-Load input is provided
by a switch or push button connected to one of the AdaptaScan I/O
in the wiring base.
To configure a Match Entry for Auto-Load:
1. On the Match Function dialog (page 11–9), select Auto-Load as
the function.
2. Use the Auto-Load Trigger Source dialog (page 11–19) to define
the trigger source.
After the AdaptaScan has been configured and running, Auto-Load
symbol data by triggering the decoder while the desired symbol is
being scanned and decoded. The Auto-Load input must be energized
before the decoder is triggered and must remain on until the decoder
trigger goes off.

DDE Through an AdaptaScan Serial Port
14–8
The AdaptaScan configuration software allows you to exchange data
and commands with other application software that supports DDE
such as Microsoft Excelt. Both software applications must be
running at the same time. DDE is supported by numerous
applications, including:
•
•
•
•
•
•
•
•
RSI Win series of software
RSDATA.vbx
Winlinks
WinView
Custom Visual Basic Drivers
Microsoft Excel
Microsoft Access
Microsoft Word
Data can be either read from or written to the Reader depending
upon the DDE function of the software. When data is read, the
Reader data (such as label data) is provided to other software. When
data is written, the Reader stores the data (such as match table rule)
or performs a function (such as reset counters).
Reader data is identified by a topic name and an address or instance
number. Providing other software packages with the Reader topic
name and address/instance allows the software to access the
corresponding data.
Note: The Monitor dialog must be closed before executing the DDE.
14–2
DDE Syntax
The DDE syntax varies between software packages. Refer to your
software instructions for the required DDE syntax. The syntax used
by Microsoft Excel is:
=Server|Topic!’Item’
Where:
Server is AS_OLP
| is the server / topic delimiter
Topic is the name of the data you want to exchange
! is the topic / item delimiter
Item specifies the node number of the data you want to exchange.
Note: If the topic name contains a space, the topic name must be
preceded and terminated by quote marks ’Topic Name’.
For example, if you wanted to have Excel show the match count of a
Reader (DeviceNet address 0) you would enter the following string
in a worksheet cell:
=AS_OLP|’MATCH COUNT’!’0’
Only one link to a topic can be made at a time. For example, you
cannot display Reader performance in more than one Excel
worksheet.

Excel Example
Here is an example of using DDE with Microsoft Excel:
1. Configure the Reader to decode a bar code (refer to Chapter 3).
These instructions assume the Reader is assigned an address of 0.
If needed, click the Device button to open the Device dialog,
change the address, and click the Apply button.
2. Click on the minimize button to reduce the AdaptaScan
configuration software to an icon. Do not exit the software.
3. Open a Microsoft Excel worksheet.
4. Enter the following data into the cells:
Cell A1: = AS_OLP|PERFORMANCE!’0’
Cell A2: =AS_OLP|LEDS!’0 2’
Cell A3: =AS_OLP|LABELS!’0’
5. The Excel worksheet will display the corresponding data from the
Reader.
Cell A1 shows the scanner performance
Cell A2 displays the Status of LED #2 Trigger/Read
Cell A3 displays the bar code data
6. Move the bar code symbol out of the scan beam. Notice how the
data displayed in the Excel worksheet automatically updates.

DDE Through the
AdaptaScan RS-232 Port
Publication 2755-838
Dynamic Data Exchange can also occur through devices connected
to an AdaptaScan RS-232 serial port. DDE through the serial port
functions the same as with the configuration cable (connected to
programming connector). To use DDE, make sure you select DF1
and enable Scanner Protocol. Shown below is an example of the
serial port setup should appear. Make sure the communication
parameters of the host device match the AdaptaScan serial port.

Extended ASCII Character Set
Publication 2755-838
A–3
Entering Non-Printable
ASCII Characters
You can enter non-printable ASCII characters into Header and
Trailer strings.
Non-printable characters may be represented by escape sequences
like \ n (Newline). The Reader interprets the \ n not as two separate
characters but as a Newline function. Each escape sequence is
preceded by a backslash \ followed by a letter or number. To enter
the \ character, use \ \.
Here are the set of escape sequences:
\a = alert (bell) character
\b = backspace
\f = formfeed
\n = newline
\r = carriage return
\t = horizontal tab
\v = vertical tab
\\ = backslash
Note: \1, \2, through \9 represent replacement string metacharacters,
refer to page C–4.
Entering Characters by Specifying Their Equivalent Value
To enter other non-printable characters, specify the hexadecimal
number equivalent value (see ASCII chart on previous page).
The format for entering a hexadecimal equivalent is \xhh where hh
is the hexadecimal value. For example; Vertical Tab = \x0B and Bell
= \x07

Preset Read Ranges
A, B, C, C+
Overview
This appendix shows the 4 preset read ranges (A, B, C, C+) for the
Catalog No. 2755-SN3, -SN5, -SN8 Readers. You can make manual
range adjustments after selecting a preset read range.
Read Ranges
The four preset read ranges allow for easy replacement of an existing
scanner. These read ranges can read bar code labels at various
distances depending on the apparent minimum element width and
scanner to label pitch.
Read Range
Data References
Read range data is based upon the following conditions:
• 95% reads minimum with reader set at maximum scan angle.
• Test label is Code 39, size reference is narrow bar.
• Label orientation on axis with 5_ pitch, 25_ skew.
Read ranges are measured from the front edge of the wiring base.
Add .58 inches (1.5 cm) for the distance to the scan window.
Read Range
Measured From This Point
Read ranges on the following charts are for preset focus ranges A, B,
C, and C+ at ambient temperature. These read ranges are based upon
Code 39 labels at 25_ skew, 5_ pitch. Typical preset read ranges will
exceed those shown. The center of the read range will shift up to
15% over the full operating temperature (0 to 50_C) of the Reader.
Different symbologies, skew, and pitch will also result in slightly
different range. Greater read range may be achieved by manually
adjusting the focus. Greater read ranges may also be obtained by
reducing the scan angle to less than 100%. Try different settings to
determine the optimum label positioning, focus range units, and scan
angle for your application.

Appendix
C
Objectives
This appendix describes metacharacters and how they may be used
in a match table rule, message find string, or replacement message.
Description
The Reader uses special characters to perform logical functions on
characters, expressions, or even entire strings. These characters are
known as metacharacters. Metacharacters are string manipulation
commands consisting of standard ASCII characters embedded within
search or replacement strings. Each metacharacter conveys a
specific instruction to the Reader, and acts upon a clearly defined
range within the string.
There are two distinct sets of metacharacters. One set applies only to
search strings and the other to replacement strings. If the Reader
encounters a search string metacharacter in a replacement string, it
will interpret it as a standard ASCII character. Conversely, if the
decoder detects a replacement string metacharacter in a search string,
it will interpret it as a standard ASCII character. For example, a “*”
in a replacement string is treated as normal text but functions as a
metacharacter in a search string.
C–2
Metacharacters
Search Pattern
Metacharacters
Use these metacharacters in the message find string or match table
rule. They cannot be used in the message pass and fail replacement
strings.
Position Dependent
Character
Description and Use
Note: The following two metacharacters are position-dependent. They
must appear in the location specified to be matched.
^
If the circumflex ( ^ ) is used as the first character in the find string, it
indicates that the characters, other metacharacters, expressions, or
strings must occur at the beginning of the string to be matched. Note
that the circumflex has a special meaning if used within square brackets,
as explained elsewhere in this chapter.
$
When the dollar sign is used as the last character in the find string, it
indicates that the characters, other metacharacters, expressions or
strings must occur at the end of the string to be matched.
Wildcard
Character
.
Description and Use
The period represents any single character, and is used as a
single-character “wildcard”.
String Manipulation
Character
Description and Use
Note: These metacharacters refer to the character, metacharacter,
string, or expression that immediately precedes them.
?
The question mark instructs the rule to match either no occurrence or
one occurrence of what precedes it. Use this metacharacter in a string
where the character may not appear at all, or may appear once.
+
The plus sign instructs the rule to match one or more occurrences of
what precedes it. Use this metacharacter in a string where the character
will be present, but you are unsure how many times it appears.
*
The asterisk instructs the rule to match none or more occurrences of
what precedes it. Use this metacharacter in a search string where the
character may not appear, or may appear one or more times.
Metacharacters
C–3
Logical Operators and Other Special Functions
Character
Description and Use
[ ]
Square brackets ( [ ] ) instructs the rule to match an incoming string if any
character enclosed within the brackets appears in the string. A range of
values can be represented within the brackets by separating the first and
last characters in the range by a hyphen. Square brackets must be used
in pairs.
Note: The circumflex ( ^ ) can be used as the first character within the
square brackets to reverse the sense of the expression.
Examples
( )
[ABC]
Matches “A”, “B”, or “C”
[L–P]
Matches “L”, “M”, “N”, “O”, or “P”
[0 – 9]
Matches “0”, “1”, “2”, “3”, “4”, “5”, “6”, “7”, “8”, or “9”
[^A – Z]
Matches any character that is not upper case
alphabetic
Parentheses can be used in two different ways. They can be used in
search patterns to group characters and metacharacters to form
expressions. Parentheses must be used in pairs.
Examples
(AB)+
The plus sign applies to the expression (AB).
Strings that would match this expression include:
“AB”, “ABAB”, “123AB”, and “AB123”.
Parentheses can also be used to identify strings for use in the Pass/Fail
Replacement String fields. If a character, string, or expression is
surrounded by parentheses in a search pattern, then it can be later
recalled in a replace pattern with the “\n” metacharacter described
elsewhere in this chapter.
Note: Parentheses may be nested to form complex expressions.
|
A vertical bar (the shifted “\” character on the keyboard) instructs the rule
to match an incoming string if the character or expression on the left or
right of the vertical bar appears in the string.
Examples
\
A|B
Matches “A” or “B”
abc|123
Matches “abc” or “123”
The backslash indicates that the following character, which would
normally be interpreted as a metacharacter, should instead be
interpreted as a literal ASCII character.
Example
\.
The period ( . ) will be interpreted as a period
rather than a single character wildcard.
C–4
Metacharacters
Replacement String
Metacharacters
Use these metacharcters in the message Pass/Fail replacement
strings. They cannot be used in the message find string or match
table rule.
Replacement String Metacharacters
Character
Description and Use
\n
The backslash plus a number 1 through 9 recalls a previously saved
string. Any character, string or expression that is surrounded by
parentheses in the Find String (as described in previous section) can be
recalled by the replace pattern using the “\n” format. Since the
parentheses may be nested, the number “n” represents the order of the
groupings as defined by the order of the left parenthesis in the search
pattern.
Examples
Find String =
Pass/Fail Replacement String =
Incoming String =
Host Message =
123(ABC)
\1
123ABC456
ABC
The Find String above matches the incoming string. The Pass/Fail
Replacement String states that the string identified within the first
parentheses should be sent to the host.
Find String =
Pass/Fail Replacement String =
Incoming String =
Host Message =
(123(ABC))
\1\2
123ABC456
123ABCABC
The Find String above matches the incoming string. The Pass/Fail
Replacement String states that the string identified within the first
parentheses (123ABC), plus the string identified by the second
parentheses(ABC) should be sent to the host.
&
When the ampersand ( & ) indicates that the part of the string that
matches the Find String should be sent to the host. If the string contains
more characters than the Find String, then the additional characters are
discarded.
Examples
Find String =
Pass/Fail Replacement String =
Incoming String =
Host Message =
123ABC
&
123ABC
123ABC
The Find String above matches the incoming string. The Pass/Fail
Replacement String states that the string identified in the Find String
should be sent to the host.
Find String =
Pass/Fail Replacement String =
Incoming String =
Host Message =
123ABC
&
123ABC456
123ABC
The Find String above matches the incoming string. The Pass/Fail
Replacement String states that the string identified in the Find String

Transmission Check
The Reader can generate three types of transmission checks:
• Longitudinal Redundancy Check.
A byte developed by an exclusive OR of all bytes in a message.
• Checksum, Most Significant Byte First
Sixteen bit sum of all the bytes in a message with the most significant
byte transmitted first.
• Checksum, Least Significant Byte First
Sixteen bit sum of all the bytes in a message with the least
significant byte transmitted first.
The following example illustrates a transmission check. The
message contains the following data:
Start Character = *
Label Delimiter = $
End of Message = CR LF
Symbol Data = ABC
The message transmits in this sequence:
* $ A B C $ $ CR LF TRANSMISSION CHECK
The table below shows the transmission check for this message.
