• The battery is a lithium ion cell and can be used without a full charge, and can
also be charged without fully discharging, without impacting the battery life.
There is no need to perform any charge/discharge conditioning on this type of
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 image
scanner.
• 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
image scanner in the base to establish a link. The green LED on the base flashes
to indicate the image scanner’s battery is charging.

Linking Image Scanner to Base
When newly shipped or defaulted to factory settings, the base and image
scanner are not linked. Once the image scanner is placed into the base, the
software automatically links the image scanner and the base. If the image
scanner and base have previously been linked, you do not receive any feedback.
If this is the first time that the image scanner and base are linked, both devices
emit a short chirp when their radios link. At this point, you are set to one image
scanner to one base.
1. Provide power to the base.
2. Place the image scanner into the base. The image scanner and base link.
3. To determine if your cordless system is set up correctly, scan one of the
sample barcodes in the back of this manual. If the image scanner provides a
single good read beep and the green LED lights, the image scanner has
successfully linked to the base. If you receive a triple error beep and the red
LED lights, the image scanner has not linked to the base. Refer to page 14-
4 for troubleshooting information.
Communication Between the Cordless System
and the Host
The cordless image scanner provides immediate feedback in the form of a “good
read” indication (a green LED on the image scanner and an audible beep) after
a barcode is scanned correctly and the base has acknowledged receiving the
data. This is possible since the cordless system provides two-way
communication between the image scanner and the base.

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

Reading Techniques
The image scanner has a view finder that projects a bright green aiming beam
that corresponds to the image scanner’s horizontal field of view. The aiming
beam should be centered over the barcode, but it can be positioned in any
direction for a good read.
The aiming beam is smaller when the image scanner 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 image scanner 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 barcodes provide instant image scanner 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 barcode below.
Keyboard wedge is the default interface.
Note: The following barcode also programs a carriage return (CR) suffix.
Laptop Direct Connect
For most laptops, scanning the Laptop Direct Connect barcode allows
operation of the image scanner in parallel with the integral keyboard. The
following Laptop Direct Connect barcode 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 barcode is used when connecting to the serial port of a PC
or terminal. The following RS-232 Interface barcode 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 image scanner decodes the barcode then sends
data in the same format as a scanner image 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.
The
Wand Emulation Plug & Play Code 39 Format
barcode below sets the
terminal ID to 61. The
Wand Emulation Plug & Play Same Code Format
barcode sets the terminal ID to 64. These Plug & Play barcodes also set the
Transmission Rate to 25 inches per second, Output Polarity to black high, and
Idle State to high. (If you want to change the terminal ID

RS-232 Receiver Time-Out
The unit stays awake to receive data until the RS-232 Receiver Time-Out
expires. A manual or serial trigger resets the time-out. When an RS-232
receiver is sleeping, a character may be sent to wake up the receiver and reset
the time-out. A transaction on the CTS line will also wake up the receiver. The
receiver takes 300 milliseconds to completely come up. Change the RS-232

Host ACK Selection
Some applications require that the host terminal (or server) approve or reject
incoming barcode data and notify the operator of these actions. These
applications require that the host maintain control over the response indicators
emitted from the source image scanner. Turning the Host ACK selection on,
configures the cordless system image scanners 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) or USB COM Emulation (terminal ID = 130).
• 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 barcode data,
make decisions based on the data content, and send out appropriate escape
commands to the source image scanner.
Escape commands are addressed to the source image scanner via “Application
Work Groups.” Once a command is sent, all image scanners in a group respond
to that command. Because of this situation, it is recommended that each
image scanner is assigned to its own group in host ACK mode.
The commands to which the image scanner 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, which is required.
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 image scanner in application work group zero
beep low, medium, high.
Once Host ACK is enabled, the system works as follows:
• The image scanner reads a code and sends data to the base/host system. No
audible or visual indication is emitted until the image scanner receives an
escape command. The image scanner read illumination goes out upon a
successful read.
• Image Scanner operation is suspended until 1) a valid escape string is
received from the host system (via the base) or 2) the image scanner “times
out.”
• Once condition 1 or 2 above has been met, the image scanner 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 image scanner 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 image scanner was not received.

In Wand Emulation mode, the image scanner decodes the barcode 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

Basic System Operation
Cordless Base
The cordless base provides the link between the cordless image scanner 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 image scanner 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 image scanner’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 image scanner 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 image scanner and base/
Bluetooth adapter, depending on the environment.
Cordless Image Scanner
The cordless image scanner enables fast and accurate barcode scanning using
a non-contact area image scanner.
The image scanner is comprised of an area image engine, a decode/control
assembly, and an RF communication module. The image engine performs the
barcode image illumination and sensing. The decode/control assembly
coordinates the central communication activities including: capturing and
decoding the barcode 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 image scanner and the base.

System Conditions
The components of the cordless system interact in specific ways as you
associate an image scanner to a base, as you move an image scanner out of
range, bring an image scanner back in range, or swap image scanners between
two cordless systems. The following information explains the cordless system
operating conditions.
Linking Process
Once an image scanner is placed into the base, the image scanner’s battery
charge status is checked, and software automatically detects the image scanner
and links it to the base depending on the selected link mode.
Image Scanner Is Out of Range
The cordless image scanner is in communication with its base, even when it is
not transmitting barcode data. Whenever the image scanner can’t communicate
with the base for a few seconds, it is out of range. If the image scanner is out of
range and you scan a barcode, the image scanner issues a triple beep indicating
no communication with the base. In addition, your image scanner and base can
sound an alarm if programmed to emit an alarm. Refer to "Out-of-Range
Alarm" on page 3-14.
Image Scanner Is Moved Back Into Range
The image scanner re-links if the image scanner or the base have been reset or
the image scanner comes back into range. If the image scanner 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 image scanner 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 image scanner produces
a series of beeps while the data is being transferred to the base.
2020/4820/4820 i 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 barcode for your application.

Unlinking the Image Scanner
If the base has an image scanner linked to it, that image scanner must be
unlinked before a new image scanner can be linked. Once the previous image
scanner is unlinked, it will no longer communicate with the base. To unlink an
image scanner from the base, scan the Unlink Image Scanner barcode below.

Locked Link Mode - Single Image Scanner
If you link an image scanner to a base using the Locked Link Mode, other image
scanners are blocked from being linked if they are inadvertently placed into the
base. If you do place a different image scanner into the base, it will charge the
image scanner, but the image scanner will not be linked.
To use a different image scanner, you need to unlink the original image scanner
by scanning the Unlink Image Scanner barcode. (See "Image Scanner
Modes" on page 3-5.)
Open Link Mode - Single Image Scanner
When newly shipped or defaulted to factory settings, the base and image
scanner are not linked. By placing an image scanner into the base, they
establish a link. Placing a different image scanner into the base establishes a
new link and the old image scanner is unlinked. Each time an image scanner is
placed into the base, it becomes the linked image scanner; the old image
scanner is unlinked.
Override Locked Image Scanner
If you need to replace a broken or lost image scanner that is linked to a base,
scan the Override Locked Image Scanner barcode below with a new image
scanner and place that image scanner in the base. The locked link will be
overridden; the broken or lost image scanner’s link with the base will be removed,
and the new image scanner will be linked.

Image Scanner Name
You may assign a name to each image scanner you are using. When you have
multiple image scanners linked to one base, you may want to name each image
scanner so you will be able to control the image scanner 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 image scanner linked to a base, and they all have the default names,
the first image scanner linked to the base receives commands. You can change
the name of an image scanner using a serial command (refer to "Image Scanner
Name" on page 12-8) or using a barcode command. To change the name
serially, unlink all except one of the image scanners from the base. Send
“:4820:BT_NAM
name
.” or “:4820i:BT_NAM
name
.”, where
name
is the new
image scanner name. If you wish to change the names of additional image
scanners, re-link them one at a time and repeat the “:4820:BT_NAM

To rename image scanners with sequential, numeric names, scan the barcodes
below.
Scan the Reset code after each name change and wait for the scanner
to re-link to the base before scanning another barcode to rename the next image
scanner.
Alternatively, you may change the name with a barcode command if you cannot
send serial commands to the base. One way to do this is to scan the barcode
below and scan a number for the image scanner name. For example, if you had
7 image scanners to one base, scan the barcode below with the first image
scanner, scan the 1 barcode on the Programming Chart inside the back cover
of this manual and scan Save. Then scan the Reset barcode and wait for the
scanner to re-link to the base before scanning the next barcode. Repeat that
process for image scanner number 2, 3, 4 etc.

Image Scanner Report
Scan the barcode below to generate a report for the connected image scanners.
The report indicates the port, work group, image scanner name, and address.
Application Work Groups
Your cordless system can have up to seven image scanners linked to one base.
You can also have up to seven work groups. If you want to have all of the image
scanners’ settings programmed alike, you don’t need to use more than one work
group. If you want each image scanner to have unique settings (e.g., beeper
volume, prefix/suffix, data formatter), then you may program each image scanner
to its own unique work group and may program each image scanner
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
barcodes used in the warehouse area versus the retail area. You could assign
all of the image scanners 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 image scanners in that particular work group.
Visual Xpress (page 11-4) makes it easy for you to program your system for use
with multiple image scanners and multiple work groups.
The image scanner keeps a copy of the menu settings it is using. Whenever the
image scanner is connected or reconnected to a base, the image scanner is
updated with the latest settings from the base for its work group. The image
scanner also receives menu setting changes processed by the base. If an image
scanner 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 image
scanner was previously assigned. For example, if the image scanner 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.

LED Power Level
This selection allows you to adjust LED and aimer brightness.
Off
is used when
no illumination is needed.
Low
is used if low illumination is sufficient.
High
(the
default) is the brightest setting.
If you have an aimer delay programmed (see Aimer Delay on page 4-10), the
aimer will be at 100% power during the delay, regardless of the LED Power
Level.
Note: If you scan the Off barcode, both the aimer and illumination lights turn off,
making it impossible to scan barcodes in low light. To turn the LED Power
Level back on, move to a brightly lit area and scan either the Low or the
High barcode below.
Illumination Lights
If you want the illumination lights on while reading a barcode, scan the Lights On
barcode, below. However, if you want to turn just the lights off, scan the Lights
Off barcode.
Note: This setting does not affect the aimer light. The aiming light can be set
using Aimer Mode (page 4-10).

Aimer Delay
The aimer delay allows a delay time for the operator to aim the image scanner
before the picture is taken. Use these codes to set the time between when the
trigger is pulled and when the picture is taken. During the delay time, the aiming
light will appear, but the LEDs won’t turn on until the delay time is over.
User-Specified Aimer Delay
If you want to set your own length for the duration of the delay, scan the barcode

Centering
Use Centering to narrow the image scanner’s field of view to make sure the
image scanner reads only those barcodes 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 image scanner can emulate the operation of older systems, such as
linear laser barcode image scanners.)
In the example below, the gray area is the full image scanner field of view and
the white area is the centering window. Barcode 1 will not be read, while
Barcode 2 will
be.
The default centering window is a 128x96 pixel area in the center of the image
scanner’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 image
scanner’s field of view, which is 640 by 480 pixels.

Decode Search Mode
There are two selectable decode (scanning) modes:
Full Omnidirectional
- Searches for barcode 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 image scanner.
Quick Omnidirectional
- This is an abbreviated search for barcode 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 barcode data will be output to the host as the image scanner
decodes it. When turned on, all output data must conform to an edited sequence
or the image scanner 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 image scanner to output
data (when scanning more than one symbol) in whatever order your application
requires, regardless of the order in which the barcodes are scanned. Reading
the
Default Sequence
symbol programs the image scanner 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 barcode 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 symbol-
ogy 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 num-
ber, 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 Barcodes, page A-6, find the Hex
value that represents the character(s) you want to match. Use the Program-
ming 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 barcodes,
but you want the image scanner 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 image scanner’s trigger. If you press and hold
the trigger, aiming the image scanner at a series of symbols, it reads unique
symbols once, beeping (if turned on) for each read. The image scanner attempts
to find and decode new symbols as long as the trigger is pulled. When this
programming selection is turned
Off
, the image scanner will only read the symbol
closest to the aiming beam.
No Read
With No Read turned

you can edit the output message using the Data Formatter (page 6-5). The hex
code for the No Read symbol is 9C.
Print Weight
Print Weight is used to adjust the way the image scanner reads Matrix symbols.
If an image scanner will be seeing consistently heavily printed matrix symbols,
then a print weight of 6 may improve the reading performance. For consistently
light printing, a print weight of 2 may help. After scanning the

Video Reverse
Video Reverse is used to allow the image scanner to read barcodes that are
inverted. The “Off” barcode below is an example of this type of barcode. If
additional menuing is required, Video Reverse must be disabled to read the
menu barcodes and then re-enabled after menuing is completed.
Note: Images downloaded from the unit will not be reversed. This is a setting for
decoding only.

Data Editing
Prefix/Suffix Overview
When a barcode is scanned, additional information is sent to the host computer
along with the barcode data. This group of barcode 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
Barcodes 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.
To Add a Prefix or Suffix:
Step 1. Scan the Add Prefix or Add Suffix symbol (page 5-4).
Step 2. Determine the 2 digit Hex value from the Symbology Chart (included in
the Symbology Chart, beginning on page A-1) for the symbology to

which you want to apply the prefix or suffix. For example, for Code 128,
Code ID is “j” and Hex ID is “6A”.
Step 3. Scan the 2 hex digits from the Programming Chart inside the back
cover of this manual or scan 9, 9 for all symbologies.
Step 4. Determine the hex value from the Code Page Mapping of Printed
Barcodes on page A-6, for the prefix or suffix you wish to enter.
Step 5. Scan the 2 digit hex value from the Programming Chart inside the back
cover of this manual.
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:
Step 1. Scan Add Suffix.
Step 2. Determine the 2 digit hex value from the Symbology Chart (included in
the Symbology Chart, beginning on page A-1) for UPC.
Step 3. Scan 6, 3 from the Programming Chart inside the back cover of this
manual.
Step 4. Determine the hex value from the Code Page Mapping of Printed
Barcodes on page A-6, for the CR (carriage return).
Step 5. Scan 0, D from the Programming Chart inside the back cover of this
manual.
Step 6. Scan Save, or scan Discard to exit without saving.

To Clear One or All Prefixes or Suffixes:
You can clear a single prefix or suffix, or clear all prefixes/suffixes for a
symbology. When you Clear One Prefix (Suffix), the specific character you
select is deleted from the symbology you want. When you Clear All Prefixes
(Suffixes), all the prefixes or suffixes for a symbology are deleted.
Step 1. Scan the Clear One Prefix or Clear One Suffix symbol.
Step 2. Determine the 2 digit Hex value from the Symbology Chart (included in

Data Formatting
Data Format Editor Introduction
You may use the Data Format Editor to change the image scanner’s output. For
example, you can use the Data Format Editor to insert characters at certain
points in barcode data as it is scanned. The selections in the following pages are
used only if you wish to alter the output.
Default Data Format setting = None.
Normally, when you scan a barcode, 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 image scanner. 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 barcode using a different data format. After the one barcode has
been read, the image scanner 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
programming 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 barcodes on the inside back
cover to program the image scanner for your terminal ID (you must
enter 3 digits). For example, scan 0 0 3 for an AT wedge.
6 - 2 2020/4820/4820 i User’s Guide
Note: The wildcard for all terminal types is 099.
Step 4. Code I.D.
In the Symbology Chart, beginning on page A-1, 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
Refer to Data Format Editor Commands (page 6-2). Scan the symbols
that represent the command you want to enter. 94 alphanumeric char-
acters may be entered for each symbology data format.
Step 7. Scan Save from the Programming Chart inside the back cover of this
manual to save your entries.
Other Programming Selections
•Clear One Data Format
This deletes one data format for one symbology. If you are clearing the
primary format, scan 0 from the Programming Chart inside the back cover of
this manual. If you are clearing an alternate format, scan 1, 2, or 3, depending
on the alternate format you are clearing. Scan the Terminal Type and Code
I.D. (see Supported Terminals on page 2-8), and the barcode data length for
the specific data format that you want to delete. All other formats remain
unaffected.

Data Formatter
When Data Formatter is turned off, the barcode data is output to the host as read
(including prefixes and suffixes). Choose one of the following options.
Default =
Data Formatter On, but Not Required.
When Data Formatter is required, all input data must conform to an edited format
or the image scanner does not transmit the input data to the host device.
Alternate Data Formats
Alternate formats allow you “single shot” capability to scan one barcode using a
different data format than your primary format. When data formats are
programmed (see page 6-1), you must input whether you are programming the
primary format, or an alternate format numbered 1, 2, or 3.
An alternate format is initiated by scanning one of the 3 alternate format
barcodes below. The image scanner will scan the next barcode, formatting the
data with the selected alternate format, then revert immediately to the primary
format.

Imaging Commands
The image scanner can be used as a digital camera for capturing, manipulating,
and transferring images.
Imaging Commands with their modifiers send imaging commands to the image
scanner on a single-use basis, and take effect for the next subsequent image
capture. Once that capture is complete, the image scanner reverts to its imaging
default settings. If you wish to change a default setting, you must use the serial
default command (see Imaging Default Commands on page 12-21). When the
serial default command is used, that selection becomes the new default setting
for the image scanner.
Image Snap - IMGSNP
An image is taken whenever the trigger of the image scanner is pressed, or when
the Image Snap (IMGSNP) command is processed. Image Snap is the
command processor for image capture, or taking a picture.
The image snap command has many different modifiers that can be used to
change the look of the image in memory. Modifiers always begin with numbers
and end with a letter (case insensitive). Any number of modifiers may be
appended to the IMGSNP command. For example, you can use the following
command to snap an image, increase the gain, and have the beeper sound once
the snap is complete:
IMGSNP2G1B
IMGSNP Modifiers
P - Imaging Style: Sets the Image Snap style.
0P Decoding Style. This is similar to the current format for decoding,
however, this processing allows a few frames to be taken until the
exposure parameters are met. Then the last frame is available for
further use.
1P Photo Style
(default).
This attempts to mimic a simple digital
camera, and results in a visually optimized image.
2P Manual Style. This is an advanced style, and should not normally
be used. It allows you the most freedom to set up the image
scanner, and has no auto-exposure.
B - Beeper: Causes a beep to sound after an image is snapped.
0B No beep
(default)
1B Sounds a beep when the image is captured, notifying the user that
the image scanner can be moved.
E - Exposure: This allows you to set the exposure time. Units are 127
microseconds. Exposure is used in Manual Style only.
(Default = 7874)

D Range: 0 - 255
L - LED State: Determines if the LEDs should be on or off, and when.
Ambient illumination (0L) is preferred for taking pictures of color documents,
such as ID cards, especially when the image scanner is in a stand. LED
illumination (1L) is preferred when the image scanner is hand held. LED State
is not available when using Decoding Style.
0L LEDs off
(default)
1L LEDs on
T - Wait for Trigger: Waits for a hardware trigger pull before taking the image.
0T Takes image immediately
(default)
1T Waits for a trigger pull, then takes the image. This option only
works with Imaging Style 1P (Photo Style). Refer to page 8-1.
U - Update Tries: The maximum number of frames the image scanner should
take to reach the Delta for Acceptance. Update Tries is only available when
using Photo Style.
(Default = 6)
n
U Range: 0 - 10
W - Target White Value: Sets the target for the median grayscale value in the
captured image. For capturing close-up images of high contrast documents,
a lower setting, such as 75, is recommended. Higher settings result in longer
exposure times and brighter images, but if the setting is too high, the image
may be overexposed. Target White Value is only available when using Photo
Style.
(Default = 125)
n
W Range: 0 - 255
% - Target Set Point Percentage: Sets the target point for the light and dark
values in the captured image. A setting of 75% means 75% of the pixels are
at or below the target white value, and 25% of the pixels are above the target
white value. Altering this setting from the default is not recommended under
normal circumstances. To alter grayscale values, Target White Value should
be used.
(Default = 50)

Image Ship - IMGSHP
An image is taken whenever the trigger of the image scanner is pressed, or when
the Image Snap (IMGSNP) command is processed. The last image is always
stored in memory. You may “ship” the image by using the IMGSHP command.
2020/4820/4820 i User’s Guide 8 - 3
The image ship command has many different modifiers that can be used to
change the look of the image output by the image scanner. Modifiers affect the
image that is transmitted, but do not affect the image in memory. Modifiers
always begin with numbers and end with a letter (case insensitive). Any number
of modifiers may be appended to the IMGSHP command. For example, you can
use the following command to ship a bitmap image with gamma correction and
document image filtering:
IMGSHP8F75K26U

S - Pixel Ship: Can be used to decimate the image by shipping only certain,
regularly spaced pixels. For example, 4S would transmit every fourth pixel
from every fourth line. The smaller number of pixels shipped, the smaller the
image. However, after a certain point, the image becomes unusable.

U - Document Image Filter: Sharpens the edges and smooths the area
between the edges of the transmitted text image. The Document Image Filter
enhances images of documents such as ID cards and prescriptions. This filter
should be used with gamma correction (see page 8-4), with the image scanner
in a stand, and the image captured using the command:
IMGSNP1P0L168W90%32D
This filter typically provides better JPEG compression than the standard E -
Edge Sharpen command (see page 8-3). This filter also works well when
shipping pure black and white images (1 bit per pixel). The optimal setting is
26U.
0U Document image filter off

W - Histogram Ship: A histogram gives a quick picture of the tonal range of
an image, or key type. A low-key image has detail concentrated in the
shadows; a high-key image has detail concentrated in the highlights; and an
average-key image has detail concentrated in the midtones. This modifier
ships the histogram for an image.

Intelligent Signature Capture - IMGBOX
Note: IMGBOX commands can only be used with PDF417, Code 39, Code 128,
Aztec, Codabar, and Interleaved 2 of 5 symbologies.
Intelligent signature capture ships only part of an image to the host application.
This method reduces transfer time and file size, while simplifying signature
capture.
Below is an example of an intelligent signature capture application. In this
example, the operator reads the barcode, which is then transmitted to the host
application. Upon the receipt of the barcode data, the host application sends the
IMGBOX command, which tells the image scanner to output only the area of the
image corresponding to the signature capture box. The image scanner also
automatically adjusts for aspect ratio and distortion, issues that arise due to
image scanner skew with respect to the barcode.
Align the aimers with the signature area (not with the barcode), then pull the
trigger. Send the IMGBOX command string after the trigger pull.
An important aspect of intelligent signature capture is that all dimensions used in
the application are measured as multiples of the minimum element size of the
barcode. Using this method, intelligent signature capture always outputs the
correct image size and resolution, no matter the distance at which the image
scanner is held from the barcode, assuming that the entire signature capture
area is within the image scanner’s field of view.
The intelligent signature capture command string for this application is:

H - Height of Signature Capture Area: In the example, the height of the area
to be captured is 1 inch, resulting in a value of H = 1/0.01 = 100. The value for
H is slightly larger, to accommodate some extra image capture area outside of
the signature capture box.
K - Gamma Correction: Gamma measures the brightness of midtone values
produced by the image. You can brighten or darken an image using gamma
correction. A higher gamma correction yields an overall brighter image. The
lower the setting, the darker the image. A setting of 100 results in no
adjustment to the image.

R - Resolution of Signature Capture Area: The number of pixels that the
image scanner outputs per each minimum bar width. The higher the value for
R, the higher the quality of the image, but also the larger the file size. To
specify a non-integer value for the resolution, use a number greater than or
equal to 1000. For example, use 2500 to specify a resolution of 2.500. The
image scanner automatically inserts a decimal point between the first and
second digit. Set to zero when using the A and B modifiers.
S - Barcode Aspect Ratio: The ratio of the barcode height to the narrow
element width. In the example, the narrow element width is .010 inches and
the barcode height is 0.400 inches, resulting in a value of S = 0.4/0.01 = 40.
W - Width of Signature Capture Area: In the example, the width of the area
to be captured is 1.90 inches, resulting in a value of W = 1.9/0.01 = 190. The
value for W is slightly larger, to accommodate some extra image capture area
outside of the signature capture box.
X - Horizontal Barcode Offset: The horizontal ratio offset of the center of the
signature capture area, in multiples of the minimum bar width. In the example,
the horizontal offset is 0.
Y - Vertical Barcode Offset: The vertical offset of the center of the signature
capture area, in multiples of the minimum bar width. Negative numbers
indicate that the signature capture is above the barcode, and positive numbers
indicate that the area is below the barcode. In the example, the horizontal
offset is 0.70 inches, resulting in a value for Y = 0.7/0.01 = 70.

RF Default Imaging Device
The image scanner supports imaging command processing (IMGSHP, IMGSNP,
IMGBOX) so that Quick*View (see "Quick*View" on page 11-5) and other
applications are able to perform imaging functions as if they were talking directly
to an image scanner. To accomplish this, the image scanner uses a menu
command called RF_DID (RF Default Imaging Device). RF_DID is the name of
the image scanner (BT_NAM) that is to receive imaging commands. The default
for RF_DID is “*”indicating that imaging commands are to be sent to all
associated image scanners. Change this setting to RF_DID

OCR Programming
Use this section to program the image scanner for optical character recognition
(OCR). The image scanner reads 6 to 60 point OCR typeface.
Note: OCR is not as secure as barcodes. To enhance security in OCR
applications, create an OCR template to match the data and print an OCR
check character.
The image scanner will read OCR-A, OCR-B, U.S. Currency Serial Number
(Money), MICR E-13B, and SEMI Font.
You can either select an OCR default, or create your own custom template for
the type of OCR format you intend to read. See "OCR" on page 9-1 for
programming codes that will enable your image scanner to read OCR-A, OCR-
B, U.S. Currency, MICR E 13 B, or SEMI fonts. See "OCR Templates" on page
9-3 if you want to create a custom “template,” or character string that defines the
length and content of OCR strings that will be read with your image scanner.
Note: Setting the template and check character options are essential for OCR
reading.

Creating an OCR Template
A single template allows you to program the image scanner to read any
combination of characters in the order you specify. Refer to examples that follow
the Template Characters table below.
Template Characters
Note: OCR templates default to eight digits, no check character.
To Add an OCR Template
1. Turn on the OCR font you want to read (page 9-2).
2. Begin building the template.
Scan the
Enter OCR Template
symbol (page 9-13).
3. Scan the characters for the string.
Use the Template Characters chart above to determine what characters you
need to create your format. Use the OCR Programming Chart (after the
Sample Codes in the back of this manual) to scan the characters for your
template.
Example: You need to read any combination of eight digits. The template would
be:
a represents any alphanumeric character (digit or letter)
c represents a check character position
d represents any digit
e represents any available OCR character
g represents character from user-defined variable “g”
h represents character from user-defined variable “h”
i represents character from user-defined variable “g” or “h”
k represents that a check character is verified but transmitted
l represents any uppercase letter
t marks the start of a new template
r multi row indicator
All other characters represent themselves. Spaces can be used.
Note: In MICR E13 B templates, TOAD characters (capital letters T, O, A, and D),
represent Transit, On Us, Amount, and Dash.

Stringing Together Multiple Formats
(Creating “Or” Statements)
You may want to program the image scanner to accept many OCR formats. To
do this, you would string together each format with a “t.” This tells the image
scanner to read optical characters that match any one of the formats in the
template.
Example: You need to read any combination of eight digits,
or
a combination of
four digits, two uppercase letters, and two digits. The template would
be:
ddddddddtddddlldd
To create this template, you would enable the OCR-A font. Scan the
Enter
OCR Template
symbol (page 9-13). Scan the
d
from the OCR Programming
Chart in the back of this manual eight times, then scan the
t
to create the “or”
statement. Then you would scan the characters for the second template.
Scan
d
four times, scan
l
two times, then scan
d
two more times. Scan
Save
OCR Template
(page 9-14). This would let you read either type of format, for
example:
99028650
or
9902XZ50
You can string together as many templates as you need.
2020/4820/4820 i User’s Guide 9 - 7
OCR User-Defined Variables
You can create up to two of your own user variables for an OCR template. These
variables will represent any OCR readable characters. The user-defined
variables are stored under the letters “g” and “h.” Creating a user variable follows
the same steps as creating a template, but instead of scanning the
Enter OCR
Template
symbol, you scan the
Enter User-Defined Variable
symbol (page 9-
13). The letters g and h can then be used in an OCR template to define the
variable you specified.
Example: You need a variable to represent the letters “A,” “B,” or “C.” The
template for this variable would be:
414243
To create this template, you would enable the OCR-A font. Scan the
Enter
User-Defined Variable
g
symbol (page 9-13). Scan
414243
from the
Programming Chart (the hex characters for “A,” “B,” and “C”). Scan
Save
OCR Template
(page 9-14). This will let you read either A or B or C in any
position where you place the g. For example, you could create the following
template:
ddddddggg
This template would then let you read data that began with six digits, and had
an A, B, or C trailing. So you would be able to read:
654321ABC
or
654321BAC
or
654321CCC
Reading Multi-Row OCR
The image scanner is capable of decoding multi-row OCR text.
Note: Reading rows longer than sixteen characters is not recommended.
Consider the following example. This example shows serial commands as they
would be entered using Quick*View.
Example: You need to read multiple rows of OCR-A data as shown below:
12345678
ABCDEFGH
First, enable the OCR-A font. To read the first row of OCR data, you would
program the following template:
9 - 8 2020/4820/4820 i User’s Guide
OCRTMP"dddddddd".
This template is the default OCR template. If you wanted to read the second
line of data, you would use the following template:
OCRTMP"llllllll".
To read both lines of OCR at one time, use the variable
r
to indicate the start
of a new row. All the other templating variables for the individual rows work
the same as previously described. For instance, in the above example, you
would use the following template to read both rows:
OCRTMP"ddddddddrllllllll".
To read the three rows below, you would use the template command
"OCRTMP"ddddddddrllllllllrlllldddd".
12345678
ABCDEFGH
ABCD1234
OCR Check Character
You may want to print and verify a check character in order to enhance the
security of your OCR application. The image scanner can be programmed for
almost any type of check character. A number of presets are provided for
common check character uses (e.g., modulo 10 and modulo 36).
Scan the
OCR Modulo 10
or
OCR Modulo 36
Check Character
barcode to
specify the type of check character used in the OCR strings you’re scanning.
The image scanner will then only read OCR character strings with a valid check
character. The image scanner transmits the OCR data without the check
character data. You must specify the location of the check character in the
template with a
c
.
Example: You need to read any combination of seven digits, with a modulo 10
check character in the eighth position. The template would be:
dddddddc
To create this template, you would enable the OCR-A font. Scan the
Modulo
10 Check Character
symbol. Then scan the
Enter OCR Template
symbol,
and scan the
d
from the OCR Programming Chart seven times, and scan the
c
once. Scan
Save OCR Template
(page 9-14). This template will let you
read any combination of six digits with a correct check character after. (If the
check character is invalid, data is discarded.) For example, the following
string could be scanned:
01234569
and the output would be: 0123456
2020/4820/4820 i User’s Guide 9 - 9
OCR Modulo 10 Check Character
Scan this symbol to program the OCR template for a simple modulo 10
checksum of the digits 0 through 9.
OCR Modulo 36 Check Character
Scan this symbol to program the OCR template for a simple modulo 36
checksum of the digits 0 through 9 and the letters A through Z.
OCR User-Defined Check Character
You can customize the check character calculation to suit your application. Each
character of the check character alphabet can be programmed in its proper
order. The number of characters you enter determines the modulo value for the
calculation. By default, the check character computation is unweighted, but the
image scanner also supports two weighted modulo 10 checking schemes.
Example:
To program a modulo 11 check character, you would enter the
following 11 characters in order:
0123456789X
Also enter the OCR template:
dddddddc
Enable the OCR-A font, then scan the following string:
6512351X
The image scanner performs the following check character computation:
(6 + 5 + 1 + 2 +3 + 5 + 1 + X) modulo 11 = 0
Since the result is zero, the message is considered to be valid, so the reader
outputs the message: 6512351

Programming a User-Defined Check Character
1. Scan the Enter OCR Check Character barcode, below.
2. Enter the characters in order. For each character, look up the corresponding
hex value from the Code Page Mapping of Printed Barcodes on page A-6.
Use the Programming Chart on the inside the back cover of this manual to
scan the two symbols for each hex value.
3. Scan the Save barcode on the inside back cover.
Example: To program the modulo 11 check character from example #8 on
page 9-9, enable the OCR-A font. Scan the Enter OCR Check
Character barcode on page 9-10, then scan the following hex values
in order:
3031323334353637383958
After you enter all the desired hex values, scan the Save barcode on the
inside back cover of this manual.
Weighting Options
By default, the check character computation is unweighted. It is possible to use
one of two weighted modulo 10 schemes. Weighting is often used to detect if
two neighboring characters are transposed, a common error when an operator
keys in data.
3-1-3-1 Weighted Modulo 10 Check Character
Starting with the check character and working backward through the message,
the image scanner applies a multiplier of 1, then 3, then 1, then 3, and so on.
This is the checking scheme used in many EAN•UCC symbologies, including
U.P.C. and Interleaved 2 of 5 (when a check digit is invoked). To apply this
weighting scheme, set the OCR check character to “0123456789x3x1” or scan
the following symbol:
Enter OCR Check Character
3-1-3-1 Weighted Modulo 10
Check Character
2020/4820/4820 i User’s Guide 9 - 11
Example: Scan the 3-1-3-1 Weighted Modulo 10 Check Character symbol. Also
enter the OCR template:
dddddddc
Then scan the string below:
01234565
The reader performs the check character computation below:
(0 x 3 + 1 x 1 + 2 x 3 + 3 x 1 + 4 x 3 + 5 x 1 + 6 x 3 + 5 x 1) modulo 10 = 0
Since the result is zero, the message is considered to be valid, so the reader
outputs the message: 0123456
2-1-2-1 Weighted Modulo 10 Check Character
Starting with the check character and working backward through the message,
the image scanner applies a multiplier of 1, then 2, then 1, then 2, and so on.
When the result of the multiplication is greater than 9, add both digits to the
running sum. This is often referred to as the LUHN formula. One common
application of the LUHN formula is validate credit card numbers. This is the
modulo 10 checking scheme used in MSI Code and in Code 32 Pharmaceutical
(PARAF). To apply this weighting scheme, set the OCR check character to
"0123456789x2x1" or scan the following symbol:
Example: Scan the 2-1-2-1 Weighted Modulo 10 Check Character symbol. Also
enter the OCR template:
ddddddc
Then scan the string below:
0128454
The reader performs the check character computation below:
(0 x 1 + 1 x 2 + 2 x 1 + 8 x 2 + 4 x 1 + 5 x 2 + 4 x 1) modulo 10
= (0 + 2 + 2 + (1 + 6) + 4 + (1 + 0) + 4) modulo 10
= 0
Since the result is zero, the message is considered to be valid, so the reader
outputs the message: 012845

OCR ISBN Application Example
One application of OCR is to read the ISBN characters typically encoded using
the OCR-A or OCR-B font. This is especially useful when the ISBN number is
not encoded in an EAN-13 barcode. The following example shows how to
configure the image scanner to read the ISBN strings on books in Japan. After
you have followed the steps below, you will be able to scan the following ISBN
number or the additional data below it, depending on the line of text at which the
image scanner is aimed.
1. Scan the OCR-B On barcode on page 9-2.
2. Program the user-defined variable “g” to comprise the ten digits plus the
dash:
0123456789-
3. In Japan, it is common for two fields to follow the ISBN number, the three
digit price field, and the four digit price field. The first field typically starts with
a “C” (uppercase c), followed by four digits. The second field typically starts
with a “P” or a yen symbol, followed by three or four digits, followed by an
“E.” Program the user-defined variable “h” to comprise the “P” and the yen
symbol (represented by a backslash).
P\
4. Scan the symbol below to set up three templates to handle the ISBN
number, the three digit price field, and the four digit price field.
2020/4820/4820 i User’s Guide 9 - 13
5. Finally, set up the ISBN check digit, which is a special position-weighted
modulo 11 checksum. The image scanner automatically invokes the ISBN
checksum for template rows that are:
1.) at least fourteen characters long,
2.) whose first four characters are the letters “ISBN,”
3.) whose last character is a check character, and
4.) when the modulo 11 check character “0123456789X” is programmed.
Please note that all these commands can be combined into a single serial
programming command:
OCRENA2,TMP”ISBNggggggggggggctCdddd hdddEtCdddd
hddddE”,GPG”0123456789-”,GPH”P\”,CHK”0123456789X”.
These commands can be encoded into the following Aztec Code symbol:

Note: This feature should not be used during normal image scanner operation.
Visual Xpress
Visual Xpress provides a wide range of PC-based programming functions that
can be performed on an image scanner connected to your PC's COM port.
Visual Xpress allows you to download upgrades to the image scanner's firmware,
change programmed parameters, and create and print programming barcodes.
Using Visual Xpress, you can even save/open the programming parameters for
an image scanner. This saved file can be e-mailed or, if required, you can create
a single barcode that contains all the customized programming parameters and
mail or fax that barcode to any location. Users in other locations can scan the
barcode to load in the customized programming.
To communicate with an image scanner, Visual Xpress requires that the PC have
at least one available serial communication port, or a serial port emulation using
a physical USB port. If you are using the serial port and RS-232 cable, an
external power supply is required. When using a USB serial port emulation, only
a USB cable is required.
Visual Xpress Operations
The Visual Xpress software performs the following operations:
Scan Data
Scan Data allows you to scan barcodes and display the barcode data in a
window. Scan Data lets you send serial commands to the image scanner and
receive image scanner response that can be seen in the Scan Data window. The
data displayed in the Scan Data window can either be saved in a file or printed.

into different categories. Each category is displayed as a tree item under the
"Configure" tree node in the application explorer. When one of these tree nodes
is clicked, the right-hand side is loaded with the parameters' form belonging to
that particular category. The "Configure" tree option has all the programming
and configuration parameters specified for an image scanner. You can set or
modify these parameters as required. You can later write the modified settings
to the image scanner, or save them to a dcf file.
Imaging
Imaging provides all the image-related functions that a 2D Image Scanner can
perform. You can capture an image using the current settings, and the image will
be displayed in an image window. Images captured from the image scanner can
be saved to files in different image formats. You can modify the image settings
and save the image settings to an INI file, which can be loaded later to capture
new images. Imaging also lets you preview the images continuously captured by
the image scanner.

Serial Programming Commands
The serial programming commands can be used in place of the programming
barcodes. Both the serial commands and the programming barcodes will
program the image scanner. For complete descriptions and examples of each
serial programming command, refer to the corresponding programming barcode
in this manual.
The device must be set to an RS-232 interface (see page 2-2). The following
commands can be sent via a PC COM port using terminal emulation software.
Conventions
The following conventions are used for menu and query command descriptions:
parameter
A label representing the actual value you should send as part of a
command.
[
option
] An optional part of a command.
{Data} Alternatives in a command.
bold Names of menus, menu commands, buttons, dialog boxes, and
windows that appear on the screen.
Menu Command Syntax
Menu commands have the following syntax (spaces have been used for clarity
only):
Prefix [:Name:] Tag SubTag {Data} [, SubTag {Data}] [; Tag SubTag {Data}] […]
Storage
Prefix Three ASCII characters: SYN M CR (ASCII 22,77,13).
:Name: To send information to the image scanner (with the base connect-
ed to host), use :4820: or :4820i: The default factory setting for a
4820 image scanner is 4820, and 4820i for a 4820i image scanner.
This setting is changed by using the BT_NAM command, which ac-
cepts alphanumeric values. If the name is not known, a wildcard
(*) can be used :*:.
Note: Since the base stores all work group settings and transfers to them to
image scanner once they are linked, changes are typically done to the
base and not to the image scanner.
Tag A 3 character case-insensitive field that identifies the desired menu
command group. For example, all RS-232 configuration settings
are identified with a Tag of 232.
SubTag A 3 character case-insensitive field that identifies the desired menu
command within the tag group. For example, the SubTag for the
RS-232 baud rate is BAD.
Data The new value for a menu setting, identified by the Tag and Sub-
Tag.
12 - 2 2020/4820/4820 i User’s Guide
Storage A single character that specifies the storage table to which the
command is applied. An exclamation point (!) performs the com-
mand’s operation on the device’s volatile menu configuration table.
A period (.) performs the command’s operation on the device’s
non-volatile menu configuration table. Use the non-volatile table
only for semi-permanent changes you want saved through a power
cycle.
Query Commands
Several special characters can be used to query the device about its settings.
^What is the default value for the setting(s).
?What is the device’s current value for the setting(s).
*What is the range of possible values for the setting(s). (The de-
vice’s response uses a dash (-) to indicate a continuous range of
values. A pipe (|) separates items in a list of non-continuous val-
ues.)
:Name: Field Usage (Optional)
This command returns the query information from the image scanner.
Tag Field Usage
When a query is used in place of a Tag field, the query applies to the
entire
set
of commands available for the particular storage table indicated by the Storage
field of the command. In this case, the SubTag and Data fields should not be
used because they are ignored by the device.
SubTag Field Usage
When a query is used in place of a SubTag field, the query applies only to the
subset of commands available that match the Tag field. In this case, the Data
field should not be used because it is ignored by the device.
Data Field Usage
When a query is used in place of the Data field, the query applies only to the
specific command identified by the Tag and SubTag fields.
Concatenation of Multiple Commands
Multiple commands can be issued within one Prefix/Storage sequence. Only the
Tag, SubTag, and Data fields must be repeated for each command in the
sequence. If additional commands are to be applied to the same Tag, then the
new command sequence is separated with a comma (,) and only the SubTag and
Data fields of the additional command are issued. If the additional command
requires a different Tag field, the command is separated from previous
commands by a semicolon (;).
2020/4820/4820 i User’s Guide 12 - 3
Responses
The device responds to serial commands with one of three responses:
ACK Indicates a good command which has been processed.
ENQ Indicates an invalid Tag or SubTag command.
NAK Indicates the command was good, but the Data field entry was out of the
allowable range for this Tag and SubTag combination, e.g., an entry for a
minimum message length of 100 when the field will only accept 2
characters.
When responding, the device echoes back the command sequence with the
status character inserted directly before each of the punctuation marks (the
period, exclamation point, comma, or semicolon) in the command.
Examples of Query Commands
In the following examples, a bracketed notation [ ] depicts a non-displayable
response.
Example #1:What is the range of possible values for Codabar Coding Enable?
Enter: cbrena*.
Response: CBRENA0-1[ACK]
This response indicates that Codabar Coding Enable (CBRENA) has a range of
values from 0 to 1 (off and on).
Example #2: What is the default value for Codabar Coding Enable?
Enter: cbrena^.
Response: CBRENA1[ACK]
This response indicates that the default setting for Codabar Coding Enable
(CBRENA) is 1, or on.
Example #3: What is the device’s current setting for Codabar Coding Enable?
Enter: cbrena?.
Response: CBRENA1[ACK]
This response indicates that the device’s Codabar Coding Enable (CBRENA) is
set to 1, or on.
12 - 4 2020/4820/4820 i User’s Guide
Example #4: What are the device’s settings for all Codabar selections?
Enter: cbr?.
Response: CBRENA1[ACK],
SSX0[ACK],
CK20[ACK],
CCT1[ACK],
MIN2[ACK],
MAX60[ACK],
DFT[ACK].
This response indicates that the device’s Codabar Coding Enable (CBRENA) is
set to 1, or on;
the Start/Stop Character (SSX) is set to 0, or Don’t Transmit;
the Check Character (CK2) is set to 0, or Not Required;
concatenation (CCT) is set to 1, or Enabled;
the Minimum Message Length (MIN) is set to 2 characters;
the Maximum Message Length (MAX) is set to 60 characters;
and the Default setting (DFT) has no value.
Trigger Commands
You can activate and deactivate the image scanner with serial trigger com-
mands. First, the image scanner must be put in Manual/Serial Trigger Mode
either by scanning the Manual/Serial Trigger Mode barcode (page 4-4), or by
sending the Manual/Serial Menu Command (page 12-9). Once the image scan-
ner is in serial trigger mode, the trigger is activated and deactivated by sending
the following commands:
Activate: SYN T CR
Deactivate: SYN U CR
The image scanner scans until a barcode has been read, until the deactivate
command is sent, or until the serial time-out has been reached (see "Read
Time-Out (Serial Trigger Mode)" on page 4-4 for a description, and the serial
command on page 12-9).

Maintenance
Repairs
Repairs and/or upgrades are not to be performed on this product. These
services are to be performed only by an authorized service center. See
"Customer Support" on page 15-1 for further information.
Maintenance
The cordless system provides reliable and efficient operation with a minimum of
care. Although specific maintenance is not required, the following periodic
checks ensure dependable operation:
Cleaning the Image Scanner’s Window
Reading performance may degrade if the image scanner’s window is not clean.
If the window is visibly dirty, or if the image scanner isn’t operating well, clean the
window with a soft cloth or lens tissue dampened with water (or a mild detergent-
water solution). If a detergent solution is used, rinse with a clean lens tissue
dampened with water only.
The image scanner and base’s housing may also be cleaned the same way.
Inspecting Cords and Connectors
Inspect the base’s interface cable and connector for wear or other signs of
damage. A badly worn cable or damaged connector may interfere with image
scanner operation. Contact your Hand Held Products distributor for information
about cable replacement. Cable replacement instructions are on page 14-2.
Do not submerge the image scanner in water. The image
scanner’s housing is not watertight.
Do not use abrasive wipes or tissues on the image
scanner’s window – abrasive wipes may scratch the
window. Never use solvents (e.g., alcohol or acetone) on
the housing or window – solvents may damage the finish
!Caution:
14 - 2 2020/4820/4820 i User’s Guide

Troubleshooting Base
Note: Please visit the Services and Support section of our website
(www.handheld.com) to check for the latest software for both the image
scanner and the base.
If your base is not functioning properly, review the following troubleshooting
guidelines to try to isolate the problem.
Is the red LED on?
If the red LED isn’t illuminated, check that:
• The power cable is connected properly and there is power at the power
source.
• The host system power is on (if external power isn’t used).
Is the green LED on?
If the
green
LED isn’t illuminated, check that:
• The image scanner is correctly placed in the base.
• There is external power or 12 volt host power.
• Charge mode is turned on. (See "Base Charge Mode" on page 3-3)
2020/4820/4820 i User’s Guide 14 - 5
• The battery is not bad or deeply discharged. In some cases, the image
scanner’s battery may trickle charge to bring it into an acceptable level and
then transition to a normal charge cycle.
Troubleshooting Image Scanner
Note: Make sure that your image scanner’s battery is charged.
Note: Please visit the Services and Support section of our website
(www.handheld.com) to check for the latest software for both the image
scanner and the base.
Is the image scanner having trouble reading your symbols?
If the image scanner isn’t reading symbols well, check that the symbols:
• Aren’t smeared, rough, scratched, or exhibiting voids.
• Aren’t coated with frost or water droplets on the surface.
• Are enabled in the base to which the image scanner connects.
Is the barcode displayed but not entered into the application?
The barcode is displayed on the host device correctly, but you still have to press
a key to enter it (the Enter/Return key or the Tab key, for example).
You need to program a suffix. Programming a suffix enables the image scanner
to output the barcode data plus the key you need (such as “CR”) to enter the data
into your application. Refer to Prefix/Suffix Overview on page 5-1 for further
information.
Does the image scanner read the barcode incorrectly?
If the image scanner reads a barcode, but the data is not displayed correctly on
the host screen:
• The base may not be programmed for the appropriate terminal interface.
For example, you scan “12345” and the host displays “@es%.”
Reprogram the base with the correct Plug and Play or Terminal selection
barcode. See Chapter 1 and Chapter 2.
• The base may not be programmed to output your barcode data properly.
For example, you scan “12345” and the host displays “A12345B.”
Reprogram the base with the proper symbology selections. See Chapter 7.
The image scanner won’t read your barcode at all.
1. Scan the sample barcodes in the back of this manual. If the image scanner
reads the sample barcodes, check that your barcode is readable.
Verify that your barcode symbology is enabled (see Chapter 7).

Code Page Mapping of Printed Barcodes
Code pages define the mapping of character codes to characters. If the data
received does not display with the proper characters, it may be because the
barcode being scanned was created using a code page that is different from the
one the host program is expecting. If this is the case, select the code page with
which the barcodes were created. The data characters should then appear
properly.
Note: The Code Page option is available for Code 39, Code 93, and Code 128.

Minimizing Bluetooth/ISM Band Network
Activity
The settings described below can help you customize the re-linking behavior of
the cordless linear imaging system to obtain the best compromise between
convenience and low interference.
Note: ISM band refers to the 2.4 to 2.48 GHz frequency band used by wireless
networks, cordless phones, and Bluetooth.
Auto Reconnect Mode
Auto Reconnect controls whether or not the image scanner automatically begins
the re-link process when a loss of connection is detected. When the Auto
Reconnect On barcode is scanned, the image scanner begins the re-link
process immediately, without user intervention.
Default = Auto Reconnect On.
The table below shows the results of the Auto Reconnect On and Off settings:
Event Auto Reconnect On Auto Reconnect Off
Image scanner out

Re-link occurs
automatically. If
maximum number of link
attempts (see Maximum
Link Attempts on page
B-2) is unsuccessful,
then the trigger must be
pulled or the image
scanner must be placed
in the base unit to re-
link.
The trigger must be pulled
to initiate re-linking.
Base reset

B - 2 2020/4820/4820 i User’s Guide
Maximum Link Attempts
The Maximum Link Attempts setting controls the number of times the image
scanner tries to form a connection with a base unit or PC. During the
connection setup process, the image scanner transmits in order to search for
and connect to a base unit. In order to prevent continuous transmissions that
could interfere with other users of the ISM band, the number of attempts to
connect is limited by this setting. After the maximum number of attempts is
reached, the image scanner will not attempt to reconnect to the base unit.
Pressing the trigger or placing the image scanner in the cradle resets the
attempt count and the image scanner will again try to link to the base unit.
When set to zero, the image scanner will try to link until the Power Time-Out
Timer setting (see page 4-4) expires.
Scan the Maximum Link Attempts barcode, then scan the number of attempts
for the setting (from 0-100) from the inside back cover. Scan Save to save the
setting.
Default = 0.

Relink Time-Out
Relink Time-Out controls the idle time between re-link attempts. An attempt to
link an image scanner to a base unit typically lasts up to 5 seconds. This is the
time when the image scanner is actually attempting to contact base unit. Relink
Time-Out controls the amount of time, in seconds, that elapses between the end
of one connection attempt and the start of the next.
Note: The length of time for an attempt depends on the number of image
scanners connected to a base unit. An extra 7 seconds may be required
when a connection is successful.
Scan the Relink Time-Out barcode, then scan the number of seconds for the
setting (from 1-100) from the inside back cover. Scan Save to save the setting.
Default = 3 seconds.
Bluetooth/ISM Network Activity Examples
Default values:
When the image scanner goes out of range, the image scanner repeatedly
attempts to connect to base unit. Each attempt consists of approximately 5
seconds of active time followed by 3 seconds of idle time. After one hour, the
image scanner powers off and batch mode data is lost.
Maximum Link Attempts set to 15
Other values at default setting:
When the image scanner goes out of range, 15 attempts are made to link to
the base unit. Each attempt consists of approximately 5 seconds of active time
followed by 3 seconds of idle time. After 15 cycles (8*15 =120), or about 2
minutes, the image scanner stops trying to connect to the base unit, but retains
any barcodes that may have been saved in batch mode. After one hour, the
image scanner powers off and batch mode data is lost.
Auto Reconnect Mode set to 0
Maximum Link Attempts set to 15
Other values at default setting:
When the image scanner goes out of range, no action is taken to re-link. When
the trigger is pulled, 15 attempts are made to link to the base unit. Each
attempt consists of approximately 5 seconds of active time followed by 3
seconds of idle time. After 15 cycles (8*15 =120), or about 2 minutes, the
image scanner stops trying to connect to the base unit, but retains any
barcodes that may have been saved in batch mode. After one hour, the image
scanner powers off and batch mode data is lost. Refer to Auto Reconnect
Mode, page B-1, to review other events that can start the re-link process.

measured from start of attempt to start of attempt. After one half hour, the
image scanner powers off.
