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.

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.
Unlink Image Scanner

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.
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.

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.
Multiple Image Scanner Operation
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

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.

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.
Image Scanner Report
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.
1 - 162020/3820 User’s Guide
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 pointto-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.
2020/3820 User’s Guide1 - 17
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:
1. Turn off power to the terminal/computer.
1 - 182020/3820 User’s Guide
2. Disconnect the keyboard cable from the back of the terminal/computer.
3. Connect the
appropriate
interface cable
to the base and
to the terminal/
computer and
keyboard. 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.
4. Turn the terminal/computer power back on.
5. Program the base for the keyboard wedge interface. See "Keyboard Wedge
Connection" on page 1-21.)
6. Verify the base operation by scanning a barcode from the Sample Symbols
in the back of this manual.
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.
2020/3820 User’s Guide1 - 19
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.
Good Read
Bad Read
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.

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.
2020/3820 User’s Guide2 - 11
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.

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).
* Manual/Serial Trigger
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
Default = 300,000 ms.

Read Time-Out
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).
3 - 42020/3820 User’s Guide
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.

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

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:
Prefix
alpha numeric &
control characters
Scanned Data
variable length1-11
Suffix
1-11

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 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.

To Add a Prefix or Suffix:
Step 1. Scan the Add Prefix or Add Suffix symbol (page 4-3).
Step 2. Determine the 2 digit Hex value from the Symbology Chart (included in
the Appendix A) 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 ASCII Conversion Chart (Code Page
1252) on page A-2, 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.

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.
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
Default Data Format setting = None.
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
2020/3820 User’s Guide5 - 1
Refer to the Supported Terminals Chart (page 2-2) 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.
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.

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 5-1), 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.

Message Length
You are able to set the valid reading length of some of the barcode symbologies.
If the data length of the scanned barcode doesn’t match the valid reading length,
the image scanner will issue an error beep. You may wish to set the same value
for minimum and maximum length to force the image scanner to read fixed length
barcode data. This helps reduce the chances of a misread.
EXAMPLE: Decode only those barcodes with a count of 9-20 characters.
EXAMPLE: Decode only those barcodes with a count of 15 characters.
For a value other than the minimum and maximum message length defaults,
scan the barcodes included in the explanation of the symbology, then scan the
digit value of the message length and Save barcodes on the Programming Chart
inside the back cover of this manual. The minimum and maximum lengths and
the defaults are included with the respective symbologies.

Codabar Concatenation
Codabar supports symbol concatenation. When you enable concatenation, the
image scanner looks for a Codabar symbol having a “D” start character, adjacent
to a symbol having a “D” stop character. In this case the two messages are
concatenated into one with the “D” characters omitted.

This function allows the image scanner to append the data from several Code 39
barcodes together before transmitting them to the host computer. When this
function is enabled, the image scanner stores those Code 39 barcodes that start
with a space (excluding the start and stop symbols), and does not immediately
transmit the data. The image scanner stores the data in the order in which the
barcodes are read, deleting the first space from each. The image scanner
transmits the appended data when it reads a Code 39 barcode that starts with a
character other than a space.

Full ASCII
If Full ASCII Code 39 decoding is enabled, certain character pairs within the
barcode symbol will be interpreted as a single character. For example: $V will
be decoded as the ASCII character SYN, and /C will be decoded as the ASCII
character #.
Character pairs /M and /N decode as a minus sign and period respectively.
Character pairs /P through /Y decode as 0 through 9.

Code 39 Code Page
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, scan the barcode below,
select the code page with which the barcodes were created from the chart, Code
Page Mapping of Printed Bar Codes on page A-4, and scan the value and the
SAVE barcode from the Programming Chart inside the back cover of this manual.
The data characters should then appear properly.
