Cordless System: Main Components

About the Battery

Use only the Li-ion battery packs provided by Hand Held Products. The
use of any battery pack not sold by Hand Held Products will void your
warranty and may result in damage to your unit.

Power is supplied to the cordless imager by a rechargeable battery that is
integrated in the imager handle. Each imager is shipped with a battery.

(See

Product Specifications

beginning on page 13-1

.)

Charging Information

The battery is designed to charge while the imager is positioned in the cordless
base unit. Refer to "2020 LED Sequences and Meaning" on page 3-4 for an
interpretation of the Charge Status indicators.

• Place the imager in the base that is connected to an appropriate power
supply.

Battery Recommendations

• Batteries are shipped approximately 30% to 60% charged and should be fully
charged for maximum charge capacity.

• The battery is a lithium ion cell and can be used without a full charge, as well
as can be charged without fully discharging, without impacting the battery life.
There is no need to perform any charge/discharge conditioning on this cell
type battery.

• Do not disassemble the battery. There are no user-serviceable parts in the
battery.

• Keep the base connected to power when the host is not in use.

• Replace a defective battery immediately since it could damage the imager.

• Don’t short-circuit a battery or throw it into a fire. It can explode and cause
severe personal injury.

• Although your battery can be recharged many times, it will eventually be
depleted. Replace it after the battery is unable to hold an adequate charge.

• If you are not sure if the battery or charger is working properly, send it to Hand
Held Products or an authorized Hand Held Products service center for
inspection.

Proper Disposal of the Battery

When the battery has reached the end of its useful life, the
battery should be disposed of by a qualified recycler or
hazardous materials handler. Do not incinerate the battery or
dispose of the battery with general waste materials. You may
send batteries to Hand Held Products (postage paid). The
shipper is responsible for complying with all federal, state, and
local laws and regulations related to the packing, labeling,

manifesting, and shipping of spent batteries. Contact the
Product Service Department (page 15-1) for recycling or disposal information.
Since you may find that your cost of returning the batteries significant, it may be
more cost effective to locate a local recycle/disposal company.

Connecting the Base

A base can be connected between the keyboard and PC as a “keyboard wedge,”
plugged into the serial port, plugged into a USB port, or connected to a portable
data terminal in wand emulation or non decoded output mode.

Turn off power before connecting the base, then power up the computer once the
base is fully connected. When the base is connected and powered up, put the
imager in the base to establish a link. The green LED on the base flashes to
indicate the imager’s battery is charging.

two screws to secure the connector to the port.

5. Plug the other serial connector into the other device connection and tighten
the two screws.

6. Plug the power supply barrel connector to the base, and plug the power
supply into the AC source.

7. Once the base has been fully connected, power up the computer.

Linking Imager to Base

When newly shipped or defaulted to factory settings, the base and imager are not
linked. Once the imager is placed into the base, the software automatically links
the imager and the base. If the imager and base have previously been linked,
you do not receive any feedback. If this is the first time that the imager and base
are linked, both devices emit a short chirp when their radios link. At this point,
you are set to one imager to one base.

2. Place the imager into the base. The imager and base link.

3. To determine if your cordless system is set up correctly, scan one of the
sample bar codes in the back of this manual. If the imager provides a single
good read beep and the green LED lights, the imager has successfully linked
to the base. If you receive a triple error beep and the red LED lights, the
imager has not linked to the base. Refer to page 14-4 for troubleshooting
information.

Communication Between the Cordless System and the
Host

The cordless imager provides immediate feedback in the form of a “good read”
indication (a green LED on the imager and an audible beep) after a bar code is
scanned correctly and the base has acknowledged receiving the data. This is
possible since the cordless system provides two-way communication between
the imager and the base.

When data is scanned, the data is sent to the host system via the base unit. The
cordless imager recognizes data acknowledgement (ACK) from the base unit. If
it cannot be determined that the data has been properly sent to the base, the
imager issues an error indication. You must then check to see if the scanned
data was received by the host system.

Reading Techniques

The imager has a view finder that projects a bright green aiming beam that
corresponds to the imager’s horizontal field of view. The aiming beam should be
centered over the bar code, but it can be positioned in any direction for a good
read.

The aiming beam is smaller when the imager is closer to the code and larger
when it is farther from the code. Symbologies with smaller bars or elements (mil
size) should be read closer to the unit. Symbologies with larger bars or elements
(mil size) should be read farther from the unit. To read single or multiple symbols
(on a page or on an object), hold the imager at an appropriate distance from the
target, pull the trigger, and center the aiming beam on the symbol. If the code
being scanned is highly reflective (e.g., laminated), it may be necessary to tilt the
code up 15° to 18° to prevent unwanted reflection.

Programming the Interface

Introduction

Chapter 1 describes connecting the base to the computer with the appropriate
interface cable. This chapter describes how to program your system for the
desired interface.

Programming the Interface - Plug and Play

Plug and Play bar codes provide instant imager set up for commonly used
interfaces.

Note: After you scan one of the codes, power cycle the host terminal to have the

interface in effect.

Keyboard Wedge Connection

If you want your system programmed for an IBM PC AT and compatibles
keyboard wedge interface with a USA keyboard, scan the bar code below.
Keyboard wedge is the default interface.

Note: The following bar code also programs a carriage return (CR) suffix.

Laptop Direct Connect

For most laptops, scanning the Laptop Direct Connect bar code allows
operation of the imager in parallel with the integral keyboard. The following
Laptop Direct Connect bar code selects terminal ID 03, programs a carriage
return (CR) suffix and turns on Emulate External Keyboard (page 2-13).

RS-232

The RS-232 Interface bar code is used when connecting to the serial port of a
PC or terminal. The following RS-232 Interface bar code also programs a
carriage return (CR) and a line feed (LF) suffix, baud rate, and data format as

indicated below. It also changes the trigger mode to manual.

Wand Emulation Plug & Play

In Wand Emulation mode, the imager decodes the bar code then sends data in
the same format as a scanner imager. The Code 39 Format converts all
symbologies to Code 39.

The Same Code Format transmits UPC, EAN, Code 128 and Interleaved 2 of 5
without any changes, but converts all other symbologies to Code 39.

The

Wand Emulation Plug & Play Code 39 Format

bar code below sets the

terminal ID to 61. The

Serial Wedge

To set up the serial wedge terminal ID, use the serial terminal ID 050 and follow
the instructions on page 2-7. Make sure that all of the communication
parameters match on all of the connected devices. Choosing Both sends
scanned data to P1 and P2. Default = P1.

Programming the Interface - Terminal ID Method

If your interface is not a standard PC AT, refer to Supported Terminals, beginning
on page 2-8, and locate the Terminal ID number for your PC. Scan the Terminal
ID bar code below, then scan the numeric bar code(s) from the Programming

Chart inside the back cover of this manual to program the imager for your

terminal ID. Scan Save to save your selection.
For example, an IBM AT terminal has a Terminal ID of 003. You would scan the

T erminal ID bar code, then 0, 0, 3 from the Programming Chart inside the back
cover of this manual, then Save. If you make an error while scanning the digits
(before scanning Save), scan the Discard code on the Programming Chart, scan
the Terminal ID bar code, scan the digits, and the Save code again.

Note: The default interface is Keyboard Wedge (Term ID = 003).

Note: After scanning one of these codes, you must power cycle your computer.

software commands from the host device. CTS/RTS operates in mode 2. When
this feature is turned

Off

, no data flow control is used. When Data Flow Control

is turned

On

, the host device suspends transmission by sending the XOFF
character (DC3, hex 13) to the imager. To resume transmission, the host sends
the XON character (DC1, hex 11). Data transmission continues where it left off
when XOFF was sent.

Default = RTS/CTS, XON/XOFF and ACK/NAKOff

.

Host ACK Selection

Some applications require that the host terminal (or server) approve or reject
incoming bar code data and notify the operator of these actions. These
applications require that the host maintain control over the response indicators
emitted from the source imager. Turning the Host ACK selection on, configures
the cordless system imagers to respond to commands from the host system.

The following criteria must be met for the Host ACK to work correctly:

• The cordless system must be configured for “Host Port RS-232” (Terminal ID
= 000)

• RTS/CTS is defaulted off. You must enable it if the host system requires it.

• Host ACK must be enabled (page 2-19).

• System performance degrades when using Host ACK at rates lower than

9600.

• The host terminal software must be capable of interpreting the bar code data,
make decisions based on the data content, and send out appropriate escape
commands to the source imager.

Escape commands are addressed to the source imager via “Application Work
Groups.” Once a command is sent, all imagers in a group respond to that
command. Because of this situation, it is recommended that each imager is
assigned to its own group in host ACK mode.

The commands to which the imager responds are listed on page 2-20. The
<ESC> is a 1B in hex. A typical command string is y <ESC> x, where “y” is the
application work group number, “<ESC> x” is the escape command, and the
comma is the terminator

.

Commands may be strung together to create custom response sequences. An
example of a command string is listed below.

0<ESC>4<ESC>5<ESC>6,

The above example will make an imager in application work group zero beep low,
medium, high.

Once Host ACK is enabled, the system works as follows:

• The imager reads a code and sends data to the base/host system. No audible
or visual indication is emitted until the imager receives an escape command.
The imager read illumination goes out upon a successful read.

• Imager operation is suspended until 1) a valid escape string is received from
the host system (via the base) or 2) the imager “times out.”

• Once condition 1 or 2 above has been met, the imager is ready to scan again,
and the process repeats.

Time out is indicated by three rapid beeps at the same pitch. A time out occurs
if the source imager does not receive a valid escape command in 10 seconds. If
a time out occurs, the operator should check the host system to understand why
a response to the imager was not received.

Wand Emulation

Wand Emulation Connection

The Wand Emulation Connection bar codes should be used if you want to
change the terminal ID

only

, without changing any other imager settings. We
recommend using Wand Emulation Plug & Play bar codes to program your
imager to emulate a wand reader. The Wand Emulation Plug & Play bar codes
change other parameters, in addition to changing the terminal ID. Please refer
to Wand Emulation Plug & Play on page 2-2 for further information.

In Wand Emulation mode, the imager decodes the bar code then sends data in
the same format as a wand scanner. The Code 39 Format converts all
symbologies to Code 39.

The Same Code Format transmits UPC, EAN, Code 128 and Interleaved 2 of 5
without any changes, but converts all other symbologies to Code 39. 2D
symbologies are converted to Code 128.

Basic System Operation

Cordless Base

The cordless base provides the link between the cordless imager and the host
system. The base contains an interface assembly and an RF communication
module. The RF communication module performs the data exchange between
the cordless imager and the interface assembly. The control assembly
coordinates the central interface activities including: transmitting/receiving
commands and data to/from the host system, performing software activities
(parameter menuing, visual indicator support, power-on diagnostics), and data
translation required for the host system.

The base also is the imager’s battery charger. Refer to "Base Charge Mode" on
page 3-3 for additional information.

RF (Radio Frequency) Module Operation

The cordless system uses a two-way Bluetooth radio to transmit and receive
data between the imager and the base. Designed for point-to-point and
multipoint-to-single point applications, the radio operates using a license free
ISM band, which sends relatively small data packets at a fast data rate over a
radio signal with randomly changing frequencies, makes the cordless system
highly responsive to a wide variety of data collection applications and resistant
to noisy RF environments. Bluetooth Class 2 power level provides a
communication range of 33 feet (10m) between the imager and base/Bluetooth
adapter, depending on the environment.

Cordless Imager

The cordless imager enables fast and accurate bar code scanning using a non­contact area imager.

The imager is comprised of an area image engine, a decode/control assembly,
and an RF communication module. The image engine performs the bar code
image illumination and sensing. The decode/control assembly coordinates the
central communication activities including: capturing and decoding the bar code
image data, performing software activities (parameter menuing, visual indicator
support, low battery indication), and data translation required for the host system.
The RF communication module performs the data exchange between the imager
and the base.

System Conditions

The components of the cordless system interact in specific ways as you
associate an imager to a base, as you move an imager out of range, bring an
imager back in range, or swap imagers between two cordless systems. The
following information explains the cordless system operating conditions.

Linking Process

Once an imager is placed into the base, the imager’s battery charge status is
checked, and software automatically detects the imager and links it to the base
depending on the selected link mode.

Imager Is Out of Range

The cordless imager is in communication with its base, even when it is not
transmitting bar code data. Whenever the imager can’t communicate with the
base for a few seconds, it is out of range. If the imager is out of range and you
scan a bar code, the imager issues a triple beep indicating no communication
with the base. In addition, your imager and base can sound an alarm if
programmed to emit an alarm. Refer to "Out-of-Range Alarm" on page 3-13.

Imager Is Moved Back Into Range

The imager re-links if the imager or the base have been reset or the imager
comes back into range. If the imager re-links, you will hear a single chirp when
the re-linking process (uploading of the parameter table) is complete.

Out of Range and Back into Range with Data Accumulation
Mode On

The imager may store a number of symbols (approximately 500 UPC symbols,
others may vary) when out of range and then send them to the base when back
in range. You will not hear a communication error beep in this mode, but you will
hear a short buzz when you pull the trigger if the radio communication is not
working. Once the radio connection is made, the imager produces a series of
beeps while the data is being transferred to the base.

2020/4820/4820i User’s Guide 3 - 3

Base Charge Mode

In order for the battery to be charged, there must be enough voltage for the
circuitry to work. There are three methods during which power can be supplied
to the base:

1: 9VDC power supply connected to the barrel connector
2: 12VDC host power source only
3: 5VDC host power source only

The chart below describes each selection by condition.

Using a slow charge rate draws less current (power) from the input power source
when the battery is mostly discharged.

Note: If you attach the 4820/4820i system to a host with a 12V power source,

the 12V host is dominant; the system pulls power from the host and not
the 9V power supply. For example, if you have a host system with a 12
volt available to the base, it will supersede the 9V power supply. The 9V
supply is not needed for 12V host applications and only serves as a
backup if the system goes down.

Scan the appropriate bar code for your application.

Default = Automatic

Unlinking the Imager

If the base has an imager linked to it, that imager must be unlinked before a new
imager can be linked. Once the previous imager is unlinked, it will no longer
communicate with the base. To unlink an imager from the base, scan the Unlink
Imager bar code below.

Locked Link Mode - Single Imager

If you link an imager to a base using the Locked Link Mode, other imagers are
blocked from being linked if they are inadvertently placed into the base. If you
do place a different imager into the base, it will charge the imager, but the imager
will not be linked.

To use a different imager, you need to unlink the original imager by scanning the
Unlink Imager bar code. (See "Imager Modes" on page 3-5.)

Open Link Mode - Single Imager

When newly shipped or defaulted to factory settings, the base and imager are not
linked. By placing an imager into the base, they establish a link. Placing a
different imager into the base establishes a new link and the old imager is
unlinked. Each time an imager is placed into the base, it becomes the linked
imager; the old imager is unlinked.

Override Locked Imager

If you need to replace a broken or lost imager that is linked to a base, scan the
Override Locked Imager bar code below with a new imager and place that imager
in the base. The locked link will be overridden; the broken or lost imager’s link
with the base will be removed, and the new imager will be linked.

Imager Name

You may assign a name to each imager you are using. When you have multiple
imagers linked to one base, you may want to name each imager so you will be
able to control the imager receiving imaging commands sent from the base.

The default name for a 4820 is “4820,” and ”4820i” for a 4820i. If you have more
than one imager linked to a base, and they all have the default names, the first
imager linked to the base receives commands. You can change the name of an
imager using a serial command (refer to "Imager Name" on page 12-8) or using
a bar code command. To change the name serially, unlink all except one of the
imagers from the base. Send “:4820:BT_NAM

name

.” or

“:4820i:BT_NAM

name

.”, where

name

is the new imager name. If you wish to
change the names of additional imagers, re-link them one at a time and repeat

Alternatively, you may change the name with a bar code command if you cannot
send serial commands to the base. One way to do this is to scan the bar code
below and scan a number for the imager name. For example, if you had 7
imagers to one base, scan the bar code below with the first imager, scan the 1
bar code on the Programming Chart inside the back cover of this manual and
scan Save. Then scan the Reset bar code and wait for the scanner to re-link to
the base before scanning the next bar code. Repeat that process for imager
number 2, 3, 4 etc.

If you want to assign an alphabetic name to the imager, create a Code 128 bar
code containing “~BT_NAM

name

.” followed by a FNC3 character (hexidecimal

83), where

name

is the new imager name. Scan the Reset bar code (page 3-8
or on the Programming Chart inside the back cover of this manual). You may

Imager Report

Scan the bar code below to generate a report for the connected imagers. The
report indicates the port, work group, imager name, and address.

Application Work Groups

Your cordless system can have up to seven imagers linked to one base. You can
also have up to seven work groups. If you want to have all of the imagers’
settings programmed alike, you don’t need to use more than one work group. If
you want each imager to have unique settings (e.g., beeper volume, prefix/suffix,
data formatter), then you may program each imager to its own unique work group
and may program each imager independently. For example, you might want to
have multiple work groups in a retail/warehouse application where you need to
have different data appended to bar codes used in the warehouse area versus
the retail area. You could assign all of the imagers in the retail area to one work
group and those in the warehouse to another. Consequently, any desired
changes to either the retail or warehouse area would apply to all imagers in that
particular work group. Visual Xpress (page 11-4) makes it easy for you to
program your system for use with multiple imagers and multiple work groups.

The imager keeps a copy of the menu settings it is using. Whenever the imager
is connected or reconnected to a base, the imager is updated with the latest
settings from the base for its work group. The imager also receives menu setting
changes processed by the base. If an imager is removed from one base and
placed into another base, it will be updated with the new base settings for
whatever work group that the imager was previously assigned. For example, if
the imager was in work group 1 linked to the first base, it will be placed in work
group 1 in the second base with the associated settings.

Read Time-Out (Serial Trigger Mode)

Use this selection to set a time-out (in milliseconds) of the imager’s trigger when
using serial commands to trigger the imager. Once the imager has timed out,
you can activate the imager either by pressing the trigger or using a serial trigger
command. After scanning the Read Time-Out bar code, set the time-out
duration (from 0-300,000 milliseconds) by scanning digits on the Programming

Chart inside the back cover, then scanning Save.

Default = 300,000 ms.

Imager Power Time-Out Timer

Note: The Imager Power Time-out Timer option only applies to Manual/Serial

Trigger.

When there is no activity within a specified time period, the imager enters low
power mode. Scan the appropriate Imager Power Time-Out bar code to change
the time-out duration (in seconds).

Note: Scanning zero (0) is the equivalent of setting no time-out.

If there are no trigger pulls during the “imager power time-out timer” interval, the
imager goes into power down mode. Whenever the trigger is enabled, the
“imager power time-out timer” is reset. If the imager is placed in the 2020 cradle
and the battery is in the process of being charged, the imager will not go into
power down mode.

Note: When the imager is in power down mode, pull the trigger to power the unit

back up. There will be a set of power up beeps and a delay of up to a few
seconds for the radio to join. The imager will then be ready to use.

Scan Stand Mode

When a unit is in Scan Stand mode, it remains idle as long as it sees the Scan
Stand symbol. (See

Scan Stand Symbol

that follows.) When a different code

is presented, the imager is triggered to read the new code.

Note:The imager automatically adjusts the illumination LEDs to the lowest light
level possible to maintain a good lock on the Scan Stand symbol. When a
symbol is presented, the imager’s light levels adjust to the saved setting (see

LED Power Level on page 4-9). This mode requires at least 50 lux of ambient

light to operate correctly.

Scan Stand Symbol

When a unit is in Scan Stand mode, the LEDs shine at the Scan Stand symbol
on the base of the stand which tells it to remain idle. When the Scan Stand
symbol is covered, the imager turns the LEDs on at the configured power level
(Default High) and attempts to find and decode bar codes in its field of view.

Presentation Mode

Note: This mode requires at least 50 lux of ambient light to operate correctly.

Scanning the bar code below programs the imager to work in Presentation Mode.
Presentation Mode uses ambient light to detect bar codes. The LEDs are off until
a bar code is presented to the imager, then the LEDs turn on automatically to
read the code. If the light level in the room is not high enough, Presentation
Mode may not work properly.

Presentation LED Behavior after Decode

When an imager is in presentation mode, the LEDs remain on and continue
scanning for a short time after a bar code is decoded. If you wish to turn the
LEDs off immediately after a bar code is decoded, scan the LEDs Off bar code,
below.

Default = LEDs On.

Presentation Sensitivity

Presentation Sensitivity is a numeric range that increases or decreases the
imager's reaction time to bar code presentation. To set the sensitivity, scan the

Sensitivity

inside back cover, and

Save

. 0 is the most sensitive setting, and 20 is the least

sensitive.

Default = 1.

Hands Free Time-Out

The Scan Stand and Presentation Modes are referred to as “hands free” modes.
If the imager’s trigger is pulled when using a hands free mode, the imager
changes to manual trigger mode. You can set the time the imager should remain
in manual trigger mode by setting the Hands Free Time-Out. Once the time-out
value is reached, (if there have been no further trigger pulls) the imager reverts
to the original hands free mode.

Centering

Use Centering to narrow the imager’s field of view to make sure the imager reads
only those bar codes intended by the user. For instance, if multiple codes are
placed closely together, centering will insure that only the desired codes are
read. (Centering can be used in conjunction with Aimer Delay, page 4-10, for
the most error-free operation in applications where multiple codes are spaced
closely together. Using the Aimer Delay and Centering features, the imager can
emulate the operation of older systems, such as linear laser bar code imagers.)

In the example below, the gray area is the full imager field of view and the white
area is the centering window. Bar Code 1 will not be read, while Bar Code 2 will
be.

The default centering window is a 128x96 pixel area in the center of the imager’s
field of view. The following diagram illustrates the default top, bottom, left, and
right pixel positions, measured from the top and the left side of the imager’s field
of view, which is 640 by 480 pixels.

If a bar code is not within the predefined window, it will not be decoded or output
by the imager. If centering is turned on by scanning

Decode Search Mode

There are two selectable decode (scanning) modes:

Full Omnidirectional

- Searches for bar code features beginning at the center
of an image, and searches to the image’s limits. This mode reads all
symbologies (including OCR), in any orientation. The Full Omnidirectional
search is very thorough which may slow performance time.

Note: This search mode is the default setting for the imager.

Quick Omnidirectional

- This is an abbreviated search for bar code features
around the center region of an image. This mode quickly reads all symbologies
in any orientation. The Quick Omnidirectional mode may miss some off-center
symbols, as well as larger Data Matrix and QR Code symbols.

Output Sequence Overview

Require Output Sequence

When turned off, the bar code data will be output to the host as the imager
decodes it. When turned on, all output data must conform to an edited sequence
or the imager will not transmit the output data to the host device.

Note: This selection is unavailable when the Multiple Symbols Selection is

turned on.

Output Sequence Editor

This programming selection allows you to program the imager to output data
(when scanning more than one symbol) in whatever order your application
requires, regardless of the order in which the bar codes are scanned. Reading
the

Default Sequence

symbol programs the imager to the Universal values,
shown below. These are the defaults. Be certain you want to delete or clear all
formats before you read the

Default Sequence

symbol.

Note: You must hold the trigger while reading each bar code in a sequence.
Note: To make Output Sequence Editor selections, you’ll need to know the code

I.D., code length, and character match(es) your application requires. Use
the Alphanumeric symbols (inside back cover) to read these options.

To Add an Output Sequence

1. Scan the

Enter Sequence

symbol (see Require Output Sequence, page 4-

16).

2. Code I.D.

On the Symbology Chart on page A-1, find the symbology to which you want
to apply the output sequence format. Locate the Hex value for that symbol­ogy and scan the 2 digit hex value from the Programming Chart (inside back
cover).

3. Length

Specify what length (up to 9999 characters) of data output will be acceptable
for this symbology. Scan the four digit data length from the Programming
Chart. (Note: 50 characters is entered as 0050. 9999 is a universal num­ber, indicating all lengths.) When calculating the length, you must count any
programmed prefixes, suffixes, or formatted characters as part of the length
(unless using 9999).

4. Character Match Sequences

On the Code Page Mapping of Printed Bar Codes, page A-6, find the Hex
value that represents the character(s) you want to match. Use the Program­ming Chart to read the alphanumeric combination that represents the ASCII
characters. (99 is the Universal number, indicating all characters.)

Output Sequence Example

In this example, you are scanning Code 93, Code 128, and Code 39 bar codes,
but you want the imager to output Code 39 1st, Code 128 2nd, and Code 93 3rd,
as shown below.

Note: Code 93 must be enabled to use this example.

You would set up the sequence editor with the following command line:

Multiple Symbols

When this programming selection is turned On, it allows you to read multiple
symbols with a single pull of the imager’s trigger. If you press and hold the

, the imager will only read the symbol closest to the aiming beam.

No Read

With No Read turned On, the imager notifies you if a code cannot be read. If
using a Quick*View Scan Data Window, an “NR” appears when a code cannot
be read. If No Read is turned

code for the No Read symbol is 9C.

Print Weight

Print Weight is used to adjust the way the imager reads Matrix symbols. If an

Data Editing

Prefix/Suffix Overview

When a bar code is scanned, additional information is sent to the host computer
along with the bar code data. This group of bar code data and additional,
user-defined data is called a “message string.” The selections in this section are
used to build the user-defined data into the message string.

Prefix and Suffix characters are data characters that can be sent before and after
scanned data. You can specify if they should be sent with all symbologies, or
only with specific symbologies. The following illustration shows the breakdown
of a message string:

Points to Keep In Mind

• It is not necessary to build a message string. The selections in this chapter
are only used if you wish to alter the default settings.

Default prefix = None.

Default suffix = None

.

• A prefix or suffix may be added or cleared from one symbology or all
symbologies.

• You can add any prefix or suffix from the Code Page Mapping of Printed Bar

Codes on page A-6, plus Code I.D. and AIM I.D.

• You can string together several entries for several symbologies at one time.

• Enter prefixes and suffixes in the order in which you want them to appear on
the output.

• When setting up for specific symbologies (as opposed to all symbologies), the
specific symbology ID value counts as an added prefix or suffix character.

Step 6. Repeat Steps 4 and 5 for every prefix or suffix character.
Step 7. To add the Code I.D., scan 5, C, 8, 0.

To add AIM I.D., scan 5, C, 8, 1.
To add a backslash (\), scan 5, C, 5, C.

Note: To add a backslash (\) as in Step 7, you must scan 5C twice – once to

create the leading backslash and then to create the backslash itself.

Step 8. Scan Save to exit and save, or scan Discard to exit without saving.
Repeat Steps 1-6 to add a prefix or suffix for another symbology.

Example: Add a Suffix to a specific symbology

To send a CR (carriage return)Suffix for UPC only:

Data Formatting

Data Format Editor Introduction

You may use the Data Format Editor to change the imager’s output. For
example, you can use the Data Format Editor to insert characters at certain
points in bar code data as it is scanned. The selections in the following pages
are used only if you wish to alter the output.

Default Data F ormat setting = None.

Normally, when you scan a bar code, it gets outputted automatically; however
when you do a format, you must use a “send” command (see Send Commands
on page 6-2) within the format program to output data.

Multiple formats may be programmed into the imager. They are stacked in the
order in which they are entered. However, the following list presents the order
in which formats are applied:

1. Specific Term ID, Actual Code ID, Actual Length

2. Specific Term ID, Actual Code ID, Universal Length

3. Specific Term ID, Universal Code ID, Actual Length

4. Specific Term ID, Universal Code ID, Universal Length

5. Universal Term ID, Actual Code ID, Actual Length

6. Universal Term ID, Actual Code ID, Universal Length

7. Universal Term ID, Universal Code ID, Actual Length

8. Universal Term ID, Universal Code ID, Universal Length
If you have changed data format settings, and wish to clear all formats and return

to the factory defaults, scan the Default Data Format code on page 6-4.

To Add a Data Format

Step 1. Scan the Enter Data Format symbol (page 6-4).
Step 2. Primary/Alternate Format

Determine if this will be your primary data format, or one of 3 alternate
formats. (Alternate formats allow you “single shot” capability to scan
one bar code using a different data format. After the one bar code has
been read, the imager reverts to the primary data format. See page 6-

5.) If you are programming the primary format, scan 0 using the Pro­gramming Chart inside the back cover of this manual. If you are pro-

gramming an alternate format, scan 1, 2, or 3, depending on the
alternate format you are programming.

Step 3. Terminal Type

Refer to Supported Terminals (page 2-8) and locate the Terminal ID
number for your PC. Scan three numeric bar codes on the inside back

Step 4. Code I.D.

In Appendix A, find the symbology to which you want to apply the data
format. Locate the Hex value for that symbology and scan the 2 digit
hex value from the Programming Chart inside the back cover of this
manual.

Step 5. Length

Specify what length (up to 9999 characters) of data will be acceptable
for this symbology. Scan the four digit data length from the Program-

ming Chart inside the back cover of this manual. (Note: 50 characters is

entered as 0050. 9999 is a universal number, indicating all lengths.)

Step 6. Editor Commands
