Cordless System: Main Components

About the Battery

Use only the Li-ion battery packs provided by Hand Held Products. The

use of any battery pack not sold by Hand Held Products will void your

warranty and may result in damage to your unit.

Power is supplied to the cordless image scanner by a rechargeable battery that

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

page 1-15 for an interpretation of the Charge Status indicators.

• Place the image scanner in the base that is connected to an appropriate

power supply.

Battery Contained in Handle

1 - 4 2020/3820 User’s Guide

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

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 (see 13-1) 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.

2020/3820 User’s Guide 1 - 5

Base Charge Mode

In order for the battery to be charged, there must be enough voltage for the

circuitry to work. There are three conditions during which power can be supplied

to the base:

Condition 1: 9VDC power supply connected to the barrel connector

Condition 2: 12VDC host power source only

Condition 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.

Scan the appropriate barcode for your application.

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

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.

2020/3820 User’s Guide 1 - 17

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.

1 - 18 2020/3820 User’s Guide

Out of Range and Back into Range with Data Accumulation Mode

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.

Keyboard Style

This programs keyboard styles, such as Caps Lock and Shift Lock.

Default =

Regular.

Regular

is used when you normally have the Caps Lock key off.

Caps Lock

is used when you normally have the Caps Lock key on.

Shift Lock

is used when you normally have the Shift Lock key on (not common

to U.S. keyboards).

Automatic Caps Lock

is used if you change the Caps Lock key on and off. The

software tracks and reflects if you have Caps Lock on or off (AT and PS/2 only).

This selection can only be used with systems that have an LED which notes the

Caps Lock status.

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

provides a means of checking character bit patterns for validity.

Default = None.

RS-232 Handshaking

RS-232 Handshaking allows control of data transmission from the image

scanner using software commands from the host device. CTS/RTS operates in

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.

2 - 12 2020/3820 User’s Guide

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.

The Wand Emulation Connection barcodes should be used if you want to change

the terminal ID

only

, 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

change other parameters, in addition to changing the terminal ID. Please refer

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).

Read Time-Out

2020/3820 User’s Guide 3 - 5

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.

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

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

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

Multiple Symbols

When this programming selection is turned

, 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

, 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.

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.

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 Appendix A) 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 ASCII Conversion Chart (Code Page

1252) on page A-2, 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.

2020/3820 User’s Guide 4 - 3

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

the Appendix A) for the symbology from which you want to clear the pre-

fix or suffix.

Step 3. Scan the 2 digit hex value from the Programming Chart inside the back

cover of this manual or scan 9, 9 for all symbologies.

Your change is automatically saved.

To Add a Carriage Return Suffix to all Symbologies

Scan the following barcode if you wish to add a carriage return suffix to all

symbologies at once. This action first clears all current suffixes, then programs

a carriage return suffix for all symbologies.

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.

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

This exits without saving any Data Format changes.

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.

2020/3820 User’s Guide 10 - 1

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.

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.

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.

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.

12 - 2 2020/3820 User’s Guide

Replacing the 2020 Interface Cable:

1. Turn the power to the host system

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.

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.

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

(firmware upgrade

or power cycle)

Image scanner behaves

as if out of range.

No attempt to re-link

made while base unit is

powered off. Trigger must

be pulled to initiate re-

linking.

* Auto Reconnect On

Auto Reconnect Off

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.

2020/3820 User’s Guide B - 3

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.

Maximum Link Attempts set to 0

Relink Time-Out set to 10

Image Scanner Power Time-Out Timer set to 1800:

Note: See Image Scanner Power Time-Out Timer on page 3-4.

The image scanner attempts to connect to the base unit every 15 seconds,

measured from start of attempt to start of attempt. After one half hour, the

image scanner powers off.
