is integrated in the image scanner handle. Each image scanner is shipped with
a battery.
(See Product Specifications
beginning on page 11-1
.)
Charging Information
The battery is designed to charge while the image scanner is positioned in the
cordless base unit. Refer to "2020 LED Sequences and Their Meaning" on

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 3820.
• 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, Inc. 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

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 3820 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.
Image Scanner Modes
The 3820 is capable of working in single image scanner mode, multiple image
scanner mode, or with Bluetooth devices, other than the 2020 base.
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.

Single Image Scanner Operation
There are two link modes to accommodate different applications: Locked Link
Mode and Open Link Mode. Scan the appropriate barcodes included in the Open
Link and Locked Link Mode explanations that follow to switch from one mode to
another.
Default = Locked Link Mode
.
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 1-6.)
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.

Multiple Image Scanner Operation
To put the image scanner in multiple image scanner mode, scan the barcode
below. Once you scan this barcode, the image scanner is unlinked from the base
and must be placed into the base to re-link.
Note: Multiple Image Scanner Operation Mode allows you to link up to 7 image
scanners to one base. You cannot join an eighth image scanner until you
unlink one of the 7 image scanners or take an image scanner out of range.
Image Scanner Name
You are able to assign a name to each image scanner you are using. It will be
helpful to name the image scanners if you have multiple image scanners linked
to one base so that you will be able to control the image scanner receiving
imaging commands sent from the base. The default name for an 3820 is “3820”.
If you have more than one 3820 linked to a base, the first image scanner that is
linked to the base receives commands addressed using this name.
Changing Image Scanner Name - Serially
If you wish to change the name, you may change it via a serial command (refer
to "Menu Command Syntax" on page 10-1) or via a barcode command. To
change the name serially, unlink all except one of the 3820s from the base. Send
“:3820:BT_NAM
name
.”, where
name
is the new image scanner name. If you
wish to change the name of additional 3820s, re-link them one at a time and
repeat the “:3820:BT_NAM
name
.”
command for each image scanner.

Changing Image Scanner Name - via Barcodes
If you wanted to set up your image scanners with names 0001-0007, you may
scan the barcodes below.
Scan the Reset barcode after each name change and
wait for the image scanner to re-link to the base before scanning the next
barcode to name 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
image scanner to re-link to the base before scanning the next barcode. Repeat
that process for image scanner number 2, 3, 4 etc.
If you want to assign an alphabetic name to the image scanner, create a Code
128 barcode containing “~BT_NAM
name
.” followed by a FNC3 character
(hexidecimal 83), where
name
is the new image scanner name. Scan the Reset
barcode (page 1-9 or on the Programming Chart inside the back cover of this
manual). You may use Barcode Builder, which is included with Quick*View. You

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. Visual XPress (page 9-1) 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.

Basic Operation of the Cordless System
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 battery charger with the external 9VDC
power source applied. Once you place the image scanner into base, the base
green LED responds according to the Charge Status Indicator table above.
The base can be powered by the Host (parasitic power mode). If the base is in
parasitic power mode without the 9VDC power source, the base will still function,
but will not charge the battery.

RF (Radio Frequency) Module Operation
The cordless system uses a state-of-the-art 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
range of 33 feet (10m) depending on the environment.
Cordless Image Scanner
The cordless image scanner enables fast and accurate barcode scanning using
a non-contact linear image scanner.
The image scanner is comprised of a linear image scanner, a decode/control
assembly, and an RF communication module. The scan 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. See Out-of-Range Alarm on
page 1-14.
Image Scanner Is Moved Back Into Range
The image scanner re-links if the image scanner or the base have been reset or
out of 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.
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.
Confirmation from the host system or the base indicates that the data sent was
received by the host. 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.
Connecting the Base When Powered by Host
(Keyboard Wedge)
A base can be connected between the keyboard and PC as a “keyboard wedge,”
plugged into the serial port, or connected to a portable data terminal in wand
emulation or non decoded output mode. The following is an example of a
keyboard wedge connection:

Note: Without using the 9-volt external, power supply, the base only uses
enough power from the host to operate the interface. The image
scanner’s battery is not charged when in this mode. Using the 9-volt,
external power supply allows the image scanner’s battery to be charged,
and no power is drawn from the host.

Reading Techniques
The image scanner has a view finder that projects a bright red aiming beam that
corresponds to its horizontal field of view. The aiming line should be centered
horizontally over the barcode; it will not read if the aiming line is in any other
direction.
The best focus point for reading most code densities is about 5 inches (12.7 cm)
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 line on the symbol.

Connecting the Base with Serial Wedge
The 2020 uses TTL signal levels to wedge into an RS-232 serial network. Use
only 2020 serial wedge cables to prevent damage to the base. Refer to
Connecting the Base with RS-232 Serial Port on page 2-8 to set the baud rate
and communications protocol.
1. Turn off power to the computer.
2. Disconnect the existing serial cable from the computer.
3. Connect the appropriate interface cable to the base. Make sure the cables
are secured in the wireways in the bottom of the base and that the base sits
flat on a horizontal surface.
Note: For the base to work properly, you must have the correct cable for your
type of computer.
4. Plug the serial connector into the serial port on your computer. Tighten the
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.

Terminal Interfaces
Terminal ID
If your interface is not a standard PC AT, refer to "Supported Terminals" on page
2-2 through page 2-3, and locate the Terminal ID number for your PC. Scan the
Terminal ID barcode below, then scan the numeric barcode(s) from the
Programming Chart inside the back cover of this manual to program the image
scanner 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
Terminal ID barcode, 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 barcode, scan the digits, and the Save code again.
Note: The default interface for the 2020-5BE is Keyboard Wedge (Term ID =
003).
Note: After scanning one of these codes, you must power cycle your computer.

RS-232 Word Length: Data Bits, Stop Bits, and Parity
Data Bits
sets the word length at 7 or 8 bits of data per character. If an
application requires only ASCII Hex characters 0 through 7F decimal (text, digits,
and punctuation), select 7 data bits. For applications which require use of the full
ASCII set, select 8 data bits per character.
Default = 8.
Stop Bits
sets the stop bits at 1 or 2.
Default = 1.
Parity

sending the XOFF character (DC3, hex 13) to the image scanner. 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/NAK Off.
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 2-12).
• 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 2-13.
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 you receive an escape command.
The image scanner read illumination goes out upon a successful read.
• Image Scanner 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.

, without changing any other image scanner settings. We
recommend using Wand Emulation Plug & Play barcodes to program your image
scanner to emulate a wand reader. The Wand Emulation Plug & Play barcodes

to Wand Emulation Plug & Play on page 1-22 for further information.
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
without any changes, but converts all other symbologies to Code 39. 2D
symbologies are converted to Code 128.

Image Scanner Trigger Modes
Manual/Serial Trigger, Low Power
You can activate the image scanner either by pressing the trigger, or using a
serial trigger command (see "Trigger Commands" on page 10-4). When in
manual trigger mode, the image scanner scans until a barcode is read, or until
the trigger is released.
When in serial mode, the image scanner scans until a barcode has been read or
until the deactivate command is sent. In serial mode, the image scanner can also
be set to turn itself off after a specified time has elapsed (see Read Time-Out
(Serial Trigger Mode), which follows).
Read Time-Out (Serial Trigger Mode)
Use this selection to set a time-out (in milliseconds) of the image scanner’s
trigger when using serial commands to trigger the image scanner. Once the
image scanner has timed out, you can activate the image scanner either by
pressing the trigger or using a serial trigger command. After scanning the Read
Time-Out barcode, 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.
Image Scanner Power Time-Out Timer
Note: The Image Scanner Power Time-out Timer option only applies to Manual/
Serial Trigger.
When there is no activity within a specified time period, the image scanner enters
low power mode. Scan the appropriate Image Scanner Power Time-Out
barcode 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 “image scanner power time-out timer”
interval, the image scanner goes into power down mode. Whenever the trigger
is enabled, the “image scanner power time-out timer” is reset. If the image
scanner is placed in the 2020 cradle and the battery is in the process of being
charged, the image scanner will not go into power down mode.
Note: When the image scanner 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 image scanner will then be
ready to use.

Presentation Mode
The LEDs are off until a barcode is presented to the image scanner. Then the
LEDs turn on automatically to read the code. Presentation Mode uses ambient
light to detect the barcodes. If the light level in the room is not high enough,
Presentation Mode will not work properly.
Hands Free Time-Out
The Automatic Trigger and Presentation Modes are referred to as “hands free”
modes. If the image scanner’s trigger is pulled when using a hands free mode,
the image scanner changes to manual trigger mode. You can set the time the
image scanner 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 image scanner reverts to the original hands free mode.

Centering Window
Use the centering feature to narrow the image scanner’s field of view so the
image scanner reads only the barcode you want. When centering is turned on,
the image scanner only reads codes that intersect or are contained within the
centering window you set up. At least part of a barcode must be within the
window to be decoded or output by the image scanner.
To change the left or right edge of the centering window, scan Centering On, then
scan one of the following barcodes. Then scan the percent you want to shift the
centering window using digits on the inside back cover of this manual. Scan
Save. Default Centering = 40% for Left, 60% for Right.
The figure below illustrates the percentage range from 1 to 100%.

Example: If you have two barcodes next to one another and the centering
window is set to 40% left edge and 60% right edge, only the barcode
that intersects that window will be decoded.
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 3-
10).
2. Code I.D.

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
On
, the image scanner sends an “NR” to the host if you pull
and release the trigger without reading a code (e.g., bad barcode). If No Read
is turned
Off
, the “NR” will not be sent to the host.
If you want a different notation than “NR,” for example, “Error,” or “Bad Code,”
you can edit the output message using the Data Formatter (page 5-5). The hex
code for the No Read symbol is 9C.
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.
Note: If additional menuing is required, Video Reverse must be disabled to read
the menu barcodes and then re-enabled after menuing is completed.

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 ASCII Conversion Chart (Code Page
1252) on page A-2, 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.

Suffix Selections
Function Code Transmit
When this selection is enabled and function codes are contained within the
scanned data, the image scanner transmits the function code to the terminal.
Charts of these function codes are provided in Supported Interface Keys starting
on page 7-3. When the image scanner is in keyboard wedge mode, the scan
code is converted to a key code before it is transmitted.
Default = Enable.
Intercharacter, Interfunction, and Intermessage Delays
Some terminals drop information (characters) if data comes through too quickly.
Intercharacter, interfunction, and intermessage delays slow the transmission of
data, increasing data integrity.
Each delay is composed of a 5 millisecond step. You can program up to 99 steps
(of 5 ms each) for a range of 0-495 ms.

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 is output automatically; however when
you do a format, you must use a “send” command (see Send Commands on
page 5-2) 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 5-4.
To Add a Data Format
Step 1. Scan the Enter Data Format symbol (page 5-4).
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 5-5.) 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 the Supported Terminals Chart (page 2-2) and locate the Ter-
minal 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.
![](/img.php?id=891328&img=bg56.png)
5 - 2 2020/3820 User’s Guide
Note: The wildcard for all terminal types is 099.
Step 4. Code I.D.
In the 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
Refer to the Format Editor Commands Chart (page 5-2). Scan the sym-
bols that represent the command you want to enter. 94 alphanumeric
characters 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 (refer to the
Supported Terminals Chart on page 2-2), Code I.D. (refer to the Symbology
Chart on page A-1), and the barcode data length for the specific data format
that you want to delete. All other formats remain unaffected.
•Save from the Programming Chart inside the back cover of this manual
This exits, saving any Data Format changes.
•Discard from the Programming Chart inside the back cover of this manual

To Add a Test Code I.D. Prefix to All Symbologies
This selection allows you to turn on transmission of a Code I.D. before the
decoded symbology. (See the Symbology Chart, included in the Appendix
A, page A-1) for the single character code that identifies each symbology.) This
action first clears all current prefixes, then programs a Code I.D. prefix for all
symbologies. This is a temporary setting that will be removed when the unit is
reset. For instructions on how to reset your image scanner, refer to Reset Image
Scanner (page 8-1).

Visual Xpress
Visual Xpress Introduction
Visual Xpress provides a wide range of PC-based programming functions that
can be performed on an imager connected to your PC's COM port. Visual
Xpress allows you to download upgrades to the imager's firmware, change
programmed parameters, and create and print programming barcodes. Using
Visual Xpress, you can even save/open the programming parameters for an
imager. 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 imager, 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 imager and receive
imager 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.
Configure
Configure displays the programming and configuration data of the imager. The
imager's programming and configuration data is grouped 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 imager. You can set or modify these parameters as
required. You can later write the modified settings to the imager, or save them
to a dcf file.
Imaging
Imaging provides all the image-related functions that a 2D Imager 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 imager 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
imager.

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 2020. 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 1-21). 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): :3820: The default factory setting for a 3820 image
scanner is 3820. This setting is changed by using the BT_NAM
command, which accepts 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 the
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.
![](/img.php?id=891328&img=bg69.png)
10 - 2 2020/3820 User’s Guide
Data The new value for a menu setting, identified by the Tag and Sub-
Tag.
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.
![](/img.php?id=891328&img=bg6a.png)
2020/3820 User’s Guide 10 - 3
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 (;).
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.
![](/img.php?id=891328&img=bg6b.png)
10 - 4 2020/3820 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 3-4), or by
sending the Manual/Serial Menu Command (page 10-11). Once the image
scanner 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 3-4 for a description, and the serial com-
mand on page 10-11).

Maintenance
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 13-1 for further information.
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 soapy
water solution). If a detergent solution is used, rinse with a clean lens tissue
dampened with water only.
The base and image scanner’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 12-2.
!Caution:
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
or the window.

Replacing the 2020 Interface Cable:
1. Turn the power to the host system
OFF.
2. Disconnect the base’s cable from the
terminal or computer.
3. Turn the base upside down.
4. Pull the connector out while
maintaining pressure on the connector
release clip.
5. Replace with the new cable.
Insert the connector into the opening
and press firmly. The connector is
keyed to go in only one way, and will
click into place.
Changing the 3820
Battery:
1. Remove the screw on the end
cap.
2. Remove the battery from the
handle.
3. Insert battery.
4. Replace end cap and screw.
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).
End Cap

2020/3820 User’s Guide 12 - 3
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 1-5)
• 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 the 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 4-1 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 6.
![](/img.php?id=891328&img=bg78.png)
12 - 4 2020/3820 User’s Guide
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 6).
2. If the image scanner still can’t read the sample barcodes, scan All
Symbologies on page 6-1.
If you aren’t sure what programming options have been set in the base, or if you
want the factory default settings restored, scan Resetting the Standard Product
Default Settings: Current Application Work Group on page 10-5.
Troubleshooting the Cordless System
The image scanner must be linked to the base for the system to work properly.
See "Linking Image Scanner to Base" on page 1-6.

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.

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

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.

B - 2 2020/3820 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 3-4) 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.
