INTRODUCTION TO THE
SCANTEAM 2380 SCANNER
1.1 Introduction
The SCANTEAM 2380 Decoder Output Scanner Keyboard Wedge is a
convenient and cost effective way of adding bar code data entry capability
to the IBM (and IBM compatible) PC/XT/AT personal computers and IBM
PS/2 Models 30, 50, 60 and 80.
Additional interfaces are continually being developed; check with Welch
Allyn or an authorized representative for availability.
As described on page 1–4, the SCANTEAM 2380 is available in the
following models: 2380/J and 2380/K with visible red illumination. All
models of the 2380 are available with stainless steel scanner housings. The
contents of this manual applies to these devices except where
differentiated.
The SCANTEAM 2380 is designed to read and decode any of nine (9)
popular bar code symbologies and output the bar code data to the keyboard
port in the same format the keyboard does.
1
1.2 Hardware Description
The SCANTEAM 2380 system consists of the wand body and a 6’ (1.8m)
coil (extended) interface cord. When connected as shown in Figure 1.1, the
2380 keyboard “wedge” device provides a transparent interface between
the keyboard and the keyboard input port of the host device.
Operation of the SCANTEAM 2380 with a particular computer is
accomplished by installing the proper “Y” interface cable and
programming the proper keyboard interface routine using the TERMINAL
SELECTION sheet of the programming menu.
Introduction to the SCANTEAM 2380
1–1
Page 12
Once installed, the 2380 simply passes keyboard activity onto the host.
Symbols decoded by the SCANTEAM 2380 are translated to
corresponding keyboard keycodes and then sent to the keyboard input port
of the terminal. Thus, the data appears as if it has been “keyed in” at the
keyboard.
Decoding capability is achieved through the use of an internal
microprocessor .
All SCANTEAM 2380 units are referred to as contact scanners since the
tip of the wand must be in or near contact with the bar code label in order
to read.

Page 13
1.3 Software Description
The standard SCANTEAM 2380 is configured for specific user
applications by scanning bar code symbols from the printed programming
menu which is supplied with the unit.
System software will support the keyboard model normally supplied with
the host device, and is capable of emulating keyboard “function keys.”
The SCANTEAM 2380 may be programmed to autodiscriminate among
the following bar code symbologies and their variations: CODABAR,
Code 3 of 9, UPC, EAN/JAN, Code 2 of 5, Interleaved 2 of 5, Code 93,
MSI, Code 128 and Code 11§.
In addition to the bar code symbology selections, certain input/output
parameters, message format and communications protocol are
programmable using the wand with the programming menu.
All programmable parameters are stored in non–volatile memory resident
in the wand where they are permanently retained in the event of power
interruption to the 2380 or the host device.
§This feature is not supported in all wand models/software revisions.

The SCANTEAM 2380 decoded output scanner keyboard wedge is
available in the following Welch Allyn industrial grade digital wand
scanner models:
SCANTEAM 2380/J and SCANTEAM 2380/K
The 2380/J and 2380/K are “SRD” scanners, meaning they have a visible
red LED illumination source. These units feature a durable body and a
replaceable tip. The 2380 has a Welch Allyn logo on the scanner housing.
Either of the models may be ordered with high, medium or low resolution
scanning optics so as to meet special requirements imposed by the label
substrate and printing method or environmental factors which affect bar
code label quality.

OPERATIONAL DESCRIPTION
2.1 Chapter Objectives
This chapter describes:
•Scanner identification key.
•Overview of how the SCANTEAM 2380 works, including scanning
aperture, depth of field and scanning velocity.
•Reading and decoding a bar code symbol. Description of print
contrast, high and low density bar code symbols.
•Discussion of RS–232 interface and external power options.
2.2 Main Elements of the 2380 Bar Code System
The major operational elements of the SCANTEAM 2380 decoded output
scanner keyboard wedge include the scanner optics, the digitizing
electronics and the decoding circuitry.
The key components of the scanner optical system are the illumination
source (LED) and the illumination sensor (photodiode). Both the LED and
photodiode are positioned directly behind a specially designed lens in the
scanner body.
2
Cable connections are made directly to the board and exit the scanner body
through a flexible strain relief at the end of the wand handle. The integral
cable shield affords EMI and associated drain protection to output signals.
Operational Description

Page 16
2.3 Scanner Identification Label
The scanner identification label is located on the scanner’s cable. The
identification corresponds to the configuration work sheet description.
(Welch Allyn p/n 16206714)
2.4 Operating Theory
The reading ability of the wand scanner is based on the detection of
reflected illumination from the bars and spaces which form a bar code
symbol.
During a typical scanning operation, the tip of the scanner is moved across
the bar code symbol. Illumination from the LED is focused on the bar
code symbol. This is absorbed by the dark colored bars and reflected by
the lighter background.
The reflected portion re–enters the scanner through the lens where it is
detected by the read sensor photodiode. The photodiode converts this into
a series of analog pulses which are proportional in width to the bars and
spaces in the symbol. These pulses are then digitized and sent to the
microprocessor where they are decoded into the characters represented by
the bar code symbol.
2.5 Factors Affecting Scanning Performance
The following factors influence reading performance and should be
considered when selecting a contact scanner for a particular bar code
application.
2.5.1Scanner Illumination Source
Wand type scanners are equipped with a visible red (660nm) source.
2–2
Operational Description
Page 17
Red illumination is compatible with most printing inks including most
thermal papers. Because it provides a visual indication to the operator that
the scanner is functioning, red illumination is considered to be more user
friendly. Visual feedback to the operator is an important consideration
when making a scanner selection.
2.5.2Scanning Aperture
Scanning performance is affected by the size of the scanning aperture and
it is a significant factor to be considered when selecting a scanner. The
scanning aperture defines the effective size of the area of the bar code
symbol viewed by the scanner optics. It affects the relative ability of the
scanning device to “see” or resolve bars and ignore printing defects.
Large aperture systems typically cannot resolve high density bar code or
the small printing features (voids within bars or dark specs within the light
areas) that small aperture systems would. Thus, they are more compatible
with low density bar code and more tolerant of printing defects
characteristic of poorly printed labels.
Small aperture systems (high resolution) are better able to resolve which
makes them compatible with high density good quality symbol reading
requirements.
The SCANTEAM 2380 is available with circular apertures ranging from 6
to 8 mil.
Most scanning applications can be satisfied with a 6 mil (high resolution)
or a 8 mil (low resolution) aperture. When selecting an aperture, it is
recommended that the aperture dimension be no less than 0.7 times the “X”
(width of the narrowest bar code coding element) dimension to be read.
An aperture size that is slightly smaller than the narrowest bar code
element, 0.9 times “X,” provides optimum resolution of the bars and results
in the generation of a digital signal which accurately represents the bar
code. An 8 mil (0.2mm) aperture is often a good compromise when labels
produced by different printing and label generation methods must be read
with one scanner. In no case should the viewing aperture exceed 1.2 the
“X” dimension.
Operational Description
2–3
Page 18
2.5.3Depth of Field
Depth of field is the maximum perpendicular distance from the scanner tip
to the bar code symbol surface at which the scanner is capable of operating
effectively. In general, most of the SCANTEAM 2380 scanners have a
depth of field of 0.065 inches (1.65mm) with a symbol appropriate for the
scanner.
A chart showing the relationships between depth of field, scanning aperture
and bar code density appears on page A–1.
In normal use, the wand is seldom held perpendicular to the surface of the
bar code symbol. Rather, an operator tends to tilt the scanner. Useable
scan angle is a function of tip geometry and depth of field. If the depth of
field is too small, the scanner may fail to operate at extreme tilt angles
(>35°).
2.5.4Scanning Velocity
The wand will operate at scan velocities from 2 to 50 inches/second (5 to
127cm per second) when the minimum bar/space size exceeds 7 mils
(0.18mm).
2.5.5High Density vs Low Density Bar Code Symbols
Bar code density is a measure of the number of characters in a linear
measure of bar code. The standard of measure is normally given in terms
of the “X” dimension, the width of the narrowest bar code element. As bar
code density increases, the width of the narrowest bar code element
decreases. The scanning aperture should always be smaller than the
narrowest element to assure optimum resolution and the generation of a
digital signal which accurately represents the bar code.
2–4
Operational Description
Page 19
2.5.6Print Contrast
Print contrast is a measure of the relative difference in brightness between
the bars and spaces of a symbol and is specified as the Minimum
Reflectivity Difference (MRD). The MRD is the difference between the
lowest minimum space reflectance value and the highest maximum bar
reflectance value as measured across the entire symbol.
MRD = Max (R
where:R
min = Minimum Space Reflectance
s
max = Maximum Bar Reflectance
R
b
max) – Min (Rs min)

The scanner will operate with a MRD as low as 37.5% with the proper
aperture and appropriate symbol.
A complete description of bar code specifications for factors which affect
overall bar code quality are provided on page A–5.

3.1 Chapter Description
This chapter describes:
•Unpacking the SCANTEAM 2380
•Connecting the SCANTEAM 2380
•Confirming scanner operation
•Checking bar code labels
3.2 Preparation
The SCANTEAM 2380 is shipped ready for use. Upon receipt, open the
carton(s) and check the contents. Check the part numbers and confirm that
each item on the packing list has been supplied.
Thoroughly inspect each component for possible shipping damage. Any
damage should be reported immediately to the carrier who delivered the
shipment. Damage claims due to handling during shipment should be
placed directly with the carrier.

Set–Up and Installation
Page 23
3.4 Scanner Checks
1)Confirm Scanner Operation
If you are using a wand which has visible red illumination, the tip of the
scanner should glow red indicating that the wand is operational. In
addition, at power–up, the beeper in the scanner should issue one (1)
“beep” (if the 2380 has been programmed to “beep” on reset).
2)Check Bar Code Labels
Before using any bar code scanner, make sure the label is of good quality
and that the window area of your scanner is clean. This is very important
because any dirt or specks in the bar code symbol or on the scanner optics
may prevent it from reading accurately. Even a label that is smudged
during printing or gets wrinkled when it is applied to an item can cause a
reading problem.
This completes installation of the wand to the host system. The wand
decoder must now be configured to the particular decoding application.
Instructions for programming the SCANTEAM 2380 decoded output

PROGRAMMING THE SCANNER
4.1 Introduction
Before the SCANTEAM 2380 can be placed in operation, it must be
configured to the particular application by scanning bar code symbols from
the Programming Menu.
As program sequences are decoded by the 2380, both the desired operating
parameters and data format instructions are stored in nonvolatile memory
on the decoder pc board. A beeper is used to indicate scanning activity.
The following relationships apply:
1)The internal beeper will emit two (2) beeps when entering or exiting
the programming mode (i.e., immediately following a scan of the
ENTER and EXIT labels, respectively).
2)When operating in the programming mode, each successful
programming entry (decoder selection) will be acknowledged by a
single “good read” beep.

4.2 The Programming Menu
The complete SCANTEAM 2380 Programming Menu consists of six (6)
pages: five Menu Pages and the Bar Code Chart. The five menu pages are
labeled: TERMINAL SELECTION, OUTPUT PARAMETERS AND
FORMAT SELECTION, COMM 1, SCANCODE SELECTION and
SYMBOLOGY SELECTION. These pages list the decoder parameters
controlled from that menu page and indicate the scanning sequence
required to make specific configuration selections. The symbols used to
control the configuration process are printed on the Bar Code Chart.
4.2.1Programming Menu Pages
All SCANTEAM 2380 programming menus follow a similar layout and
contain the same programming elements. A typical programming menu
page is shown in Figure 4.1.

The general elements found on each menu page include:
(1)A “USE THIS PAGE” statement that indicates the programming
options (capabilities) which appear on that menu page.
(2)The SELECTIONS/VARIABLES table which lists primary
programming selections, variables which can be used to modify the
basic selection and the bar code scanning sequence that must be used
to configure the scanner to these values.
Three discrete bar code commands perform global menu selections and
control movement between the different menu pages.
These discrete commands include:
(3)An ENTER command. Scanning this bar code symbol will activate
that particular menu page. The ENTER code for each menu page is
unique, and must be scanned before configuring commands from that
page will be recognized by the scanner.
(4)A generic DEFAULT command which, when scanned, causes all of
the programming selections/variables which appear on that particular
menu page to automatically default to the values marked by an
asterisk(*). Entering a DEFAUL T instruction before beginning to
program brings all of the parameters on that page to a known value
and thus helps to avoid programming confusion.
(5)The EXIT command is used to conclude programming on the active
menu page. The EXIT symbol must be scanned before moving to
another page of the programming menu.
Information regarding special bar code applications is often provided at the
bottom of menu pages. These include:
(6)The special NOTES used to explain unusual programming
requirements and/or refer the user to necessary information or

Note that the chart contains symbol groupings that include ROMAN
NUMERALS, LETTERS and NUMBERS. The sequence in which these
symbols are scanned generates the programming instructions which enable
or disable specific decoder functions.
The right hand column of the Chart contains three (3) bar code symbols
labeled DEFAUL T, ESCAPE and EXIT. When these symbols are scanned
specific instructions are instantaneously sent to the wand.
The function of these commands is explained below.
DEFAULT
Scanning this symbol installs default values (indicated by *’s) at the active
programming level. For example, if the DEFAUL T symbol is scanned
immediately following Page ENTER, it defaults the entire menu page. If it
is scanned following a major category selection like Codabar, it will default
that whole category. If DEFAULT is scanned following a subcategory
selection such as Code 128/Minimum Length, it will default just that
subcategory.
EXIT
Scanning the EXIT symbol produces a command which can be used to
terminate programming on either menu page. The EXIT symbol must be
scanned before moving to or attempting to program on a different menu
page. When it is scanned, all configuration instructions for parameters
appearing on that page will be stored in memory.
ESCAPE
Scanning the ESCAPE symbol generates a command that will terminate a
programming sequence before it is completed and without saving the
configuration information. It can be used when a Selection and/or Variable
has been scanned in error. The programming sequence must then be
restarted.

4.3 DIRECT CONNECT TERMINAL SELECTION Menu
Page
This menu page is used to make a direct connect terminal selection An
explanation of programmable selections follows.
Direct Connect Terminal Selection
The terminals that may be selected by scanning the appropriate direct
connect bar code are IBM AT and compatibles, IBM XT and compatibles,
and IBM PS/2 Model 30. The IBM AT, XT or PS/2 is configured by
scanning the one bar code on this page, instead of scanning the ENTER
code, the two digit terminal identifier code and the EXIT code on the
TERMINAL SELECTION menu page.
4.4 TERMINAL SELECTION Menu Page
This menu page lists the types of host devices which are supported by the
2380, and shows the scanning sequence that should be used to configure
the scanner interface to be compatible with a particular host PC.
4.5 OUTPUT P ARAMETERS & FORMA T SELECTION Menu
Page
This menu page contains parameter selections used to control the data
message that will be sent from the scanner to the host. An explanation of
programmable selections follows.
Preamble
Preambles are assigned using the programming menu. When the Preamble
selection is enabled, any combination of up to five (5) identifiers are
transmitted as a header immediately preceding scanned bar code data.
4–6
Programming the Scanner
Page 31
Preamble characters may include Code ID and the ASCII characters
(00–7F). These characters will be transmitted in the order in which the
selections are programmed.
Both preamble and postamble menuing must always start with a clean
slate. Therefore, to clear all preambles, it is necessary only to complete the
programming sequence SCAN ENTER, SCAN I, SCAN EXIT.
If the Code ID is selected as a preamble, the wand will transmit a single
lower case ASCII character to identify which symbology was decoded.
For example, Code 3 of 9 is identified by a lower case “b,” while Code 128
is identified by a lower case “j.”
The code identifier for each bar code symbology is listed below and
appears immediately following the symbology name on the Symbology
Selection Menu Page.

Postamble
Postamble(s) are programmable data identifiers which follow the bar code
messages. Up to five (5) postambles which include the ASCII characters
(00–7F) can be programmed. Postamble characters will be transmitted in
the order in which they are selected. Since postamble selections also begin
with a clean slate, the programming sequence SCAN ENTER, SCAN II,
SCAN EXIT will remove existing postambles from the decoder
configuration.

Function TX (Transmit)
When this menu selection is enabled, and function codes are contained
within the scanned data, the SCANTEAM 2380 transmits the key code to
the terminal which corresponds to the decoded ASCII function code.
ASCII function codes are represented by the HEX values (00–1F).
When the Function Code Transmit selection is disabled, the scanner does
not transmit the key codes which correspond to the HEX characters 01–1F
unless they are in preambles or postambles. Instead, the characters 01–1F
are stripped from the bar code data. Any keyboard function codes within
data in the preamble and postamble will be sent to the terminal regardless
of the parameter. Function codes in preambles and postambles are
automatically translated to key codes.
Note:Care should be taken not to embed keyboard function codes that will
cause an input inhibit condition within records, preambles, and
postambles. Attempts to embed function codes may result in loss of
data.
Example – Keyboard Function Codes (Commercial Application):
The SCANTEAM 2380 is connected to an IBM PC; Keyboard Function
Codes within scanned data and the Preamble and Postamble on the COMM
1 section of the Programming Menu.
The SCANTEAM 2380 is programmed as follows:
Preamble: GS (1D)==>F10 key
Postamble:CR (OD)==>ENTER key
Full ASCII Code 3 of 9 Decoding: enabled
Note:When programming preambles and postambles you must scan a
symbology before scanning in a scan code.
Consider the case of a Code 3 of 9 bar code symbol:
1 2 3 4 “HT” 5 6 7 8
The function emulated depends not only upon the Keyboard Function
Code, but also upon the terminal being used with the SCANTEAM 2380.
Appendix C lists, by terminal type, the key function emulated by each
Keyboard Function Code. (The codes in the center column change.)

CASE 1 – Function Codes “Enabled”
With the Function Code Transmit selection enabled, the SCANTEAM 2380
outputs 1234HT5678 to the terminal as:
F101 2 3 4 “TAB ”5 6 7 8ENTER
preamblepostamble
Notice that Keyboard Function Code, HT, has been translated and sent as
the TAB key.
CASE 2 – Function Codes “Disabled” (Commercial Application):
When the Function Code Transmit selection is disabled, the SCANTEAM
2380 outputs 1234HT5678 to the terminal as:
F101 2 3 4 5 6 7 8ENTER
Notice now that HT has been stripped from the data string. Note also, that
Keyboard Function Codes contained within the Preamble and Postamble
(F10 and ENTER) are not affected by the Function Code Transmit
selection (XII) and so they are translated and sent.
Keyboard Function Records
Keyboard Function Records are special incoming data records which
originate from the Scanner.
Keyboard Function Records are translated by the SCANTEAM 2380 and
sent to the terminal as keyboard function keys. The function which is
emulated depends upon both the Keyboard Function Record and the
terminal selection. The key functions emulated by each Keyboard
Function Record are listed according to terminal type in Appendix C.
Keyboard Function Records differ from Keyboard Function Codes in the
following ways:
(1)Keyboard Function Records cannot be disabled by menu
programming.
(2)Keyboard Function Records cannot be embedded within other
Scanner data; they are stand alone records, and if embedded, will be
treated as normal data.
Programming the Scanner
4–9
Page 34
(3)When Keyboard Function Records are entered, any
Preambles/Postambles which may have been programmed will not be
added to the output transmission.
Example: Keyboard Function Records (Commercial Application)
The following examples illustrate the effect of Keyboard Function Records
on data transmission.
Scanner Data
In this example the SCANTEAM 2380 is connected to an IBM PC, and the
function key F10 is to be emulated using a Keyboard Function Record
entered through the Scanner. The symbology Full ASCII Code 3 of 9 has
been enabled.
When configured in this way, scanning a Code 3 of 9 label containing the
following characters:
/ C 3 1
will produce a decoded output of (#31).
Keyboard Type
This menu selection permits you to program the 2380 to output data using
the following keyboard operating modes: NORMAL, CAPS LOCK, CRTL
+ AND SHIFT LOCK.
NORMAL
This is the Primary Type keyboard selection. When NORMAL is enabled,
the 2380 will output scanned data to the terminal in conventional bar code
format.
CAPS LOCK
When you are operating in CAPS LOCK mode, the 2380 should also be
programmed for CAPS LOCK mode (i.e., CAPS LOCK enabled).
CTRL + When the 2380 is programmed to operate in CTRL + mode,
ASCII function codes 00 to 1F are sent to the terminal through a CTRL +
sequence (i.e., “CR” = CTRL + M).
4–10
Programming the Scanner
Page 35
SHIFT LOCK
When you are operating in SHIFT LOCK mode, the 2380 should also be
programmed for SHIFT LOCK mode (i.e., SHIFT LOCK enabled).
Intercharacter Delay
Intercharacter Delay is the time delay between data characters output by
the 2380. The delay is in (X5) milliseconds and can be set to any value
between 00 and 99 (X5ms).
Interfunction Delay
Interfunction delay is the time delay between “function key” characters
output by the 2380. The delay is in (X5) milliseconds, and any value
between 00 and 99 (X5ms) may be selected.
Intermessage Delay
Intermessage delay is the time delay between messages output by the 2380.
The delay is in (X5) milliseconds and can be set to any value between 00
and 99 (X5ms).
Beeper
This programming selection permits control of the beeper located in the
scanner as a means of indicating scanning activity to the operator. The
BEEPER option described below is listed on the Programming Menu.
Beep (On Reset)
When “Beep” (On Reset) is enabled (YES), the beeper in the scanner will
“beep once” to indicate that the wand is operational. This single “beep” can
be interpreted as a SCANNER READY message from the wand.
Beep (On Good Read)§
When “Beep” (On Good Read) is enabled (YES), the beeper in the scanner
will “beep once” following a scan only if the bar code data has been
accepted by the host. If the beeper does not sound, the scan should be
repeated.

Append Buffer
This scanner selection controls the status of the Append Buffer . When
enabled, the Append Buffer stores messages (for example from a
“barboard”), until a) it overflows, or b) a symbol without Append or in a
new symbology is scanned. When either of these events occur, the
contents of the buffer are transmitted, followed by the most recent scan.
Note:The Append Buffer must be enabled (YES), whenever the decoder is
configured to read Code 93, Code 128 or Code 3 of 9 symbology with
Append Option.
4.6 COMM 1 Menu Page§
The COMM 1 page of the Programming Menu is used to select a
international keyboard and to reconfigure the 2380 for Intermec
compatibility . An explanation of programmable selections follows.

Intermec Capability§
Scanning the “Yes” bar code allows the 2380 to be compatible with the
Intermec keyboard function codes. Scanning the “No” bar code symbol
causes the 2380 default keyboard codes in the preamble and postamble to
remain active at all times. The default selection is “No.”
4.7 SCANCODE SELECTION Menu Page
This menu page is used to select K2 scancode capability, new keyboard
scancode table, beep PC, numeric keypad and RX interrupt. An
explanation of programmable selections follows.
K2 Scancode Compatibility
This selection only applies to customers using AT, XT, or PS/2’s. If this
selection is enabled (YES), the 2380 will use the same scancodes as the
Welch Allyn SCANTEAM 2300 (K2). If this selection is disabled, the
2380 will use the scancodes found in Appendix C. All other terminals use
K2 scancode tables which also appear in Appendix C.
New Keyboard Scancode Table
If the SCANTEAM 2380 has been downloaded to contain another
scancode table, programming this selection to “Yes” will cause the new
scancode table to be used, rather than the normal scancode table. This
menu selection is applicable for use with terminals not equipped with
standard manufacturer’s keyboards (that is, international keyboards).
Beep PC§
When this menu selection is enabled (YES), the 2380 will beep the PC on a
good read. This selection must be disabled (“No”) when “Beep on Reset”
(OUTPUT PARAMETERS) is enabled.
Note:The master DEFAUL T bar code on this menu page does not return
this parameter to its default setting.
Numeric Keypad§
When “main keyboard numbers ” is selected, numbers will be sent to the
host terminal as if keyed in from the main keyboard. If “numeric keypad”
is enabled, numbers will be sent as if keyed in from the numeric keypad.
Note:The master DEFAUL T bar code on this menu page does not return
this parameter to its default setting.
Programming the Scanner
4–13
Page 38
RX Interrupt§
Occasionally, keyboard activity will cause the wand to beep intermittently
or turn off. This menu selection will prevent this from happening.
4.8 SYMBOLOGY SELECTION (CODES) Menu Page
This Menu Page is used to program decoding selections. The 2380 can be
configured to recognize and decode up to nine (9) popular bar code
symbologies by scanning the proper code enabling (Selection) symbols on
this Programming Menu page. After a particular code has been enabled,
scanning the associated (Variable) code(s) will further program that
symbology’ s decoding parameters.
Keep in mind that at power–up (or upon reset), the wand will automatically
configure operating parameters to the last programmed values. Code
options which are enabled (YES) will become the active operating
parameters unless they are changed by the proper configuration command.
Code options with an asterisk (*) next to the (NO) will automatically be
disabled unless they are changed by the proper configuration command.
Note:To obtain maximum security when scanning bar codes, it is
recommended that only those symbologies actually being used be
enabled. Symbologies not being used should be disabled. Additional
data security can be achieved by programming the maximum and
minimum character counts when they are known.
Minimum Length
A two (2) number code which describes the minimum number of characters
that will permitted in the bar code message. The code length must always
be represented by two digits. For lengths less than 10 characters, a zero (0)
should be used as a filler, for example, (05).
Maximum Length
A two (2) number code which describes the maximum number of
characters that will be permitted in the bar code message.

4.9 Message Format
The wand will transmit data automatically to the host as soon as a bar code
symbol is scanned. Each data transmission consists of three main
elements, 1) a PREAMBLE, 2) the MESSAGE consisting of the bar code
data, and 3) a POSTAMBLE.
The actual content of the data transmission will depend upon the Preamble
and Postamble characters and the decoded bar code information. The
transmission format is shown below.

4.11Keyboard Layouts and Delimiters
A delimiter is the unique keycode generated by a particular terminal key
whenever it is depressed. Every key on the keyboard is assigned its own
code. The terminal uses these codes to identify the key that was depressed,
and the function that key represents.
The SCANTEAM 2380 can be programmed to recognize these function
keycodes as field delimiters. When field delimiters are used to separate bar
code data, the terminal interprets the data codes produced by scanning a bar
code symbol(s) as originating from the keyboard without the function key
being depressed.
Delimiters for a particular terminal can be determined by referring to the
keyboard layouts provided on the Keyboard Layouts page of the
programming menu. Refer to Figure 4.3 for an example of the keyboard
layout for an NCR 7052/32 and 56 key terminal.

Note that certain keys are marked with a number and letter. These
designations (i.e., the A1, A5, C3 etc.) are the delimiters associated with
that particular function key.
Once the delimiters have been programmed, the SCANTEAM 2380
automatically generates the proper keycode and sends it to the terminal just
as though the terminal function key had been depressed.

MAINTENANCE AND TROUBLESHOOTING
5.1 Scanner Maintenance And Service
All Welch Allyn SCANTEAM 2380 units are designed to provide reliable
and efficient operation with a minimum of care. Although specific
maintenance is not required, the following periodic checks will contribute
significantly to dependable scanner operation.
5.2 Cleaning
The sapphire tip is designed to be maintenance free, but may be cleaned
when necessary. The tip of the scanner must be kept clean to assure high
first pass reading performance. Since a dirty tip can impair scanning
performance, the tip should be examined whenever scanning performance
begins to degrade or if the tip has become visibly dirty.
If the tip becomes dirty, it should be cleaned by wiping with a soft cloth or
facial tissue that has been dampened with a mild detergent and water
solution. The scanner enclosure can also be cleaned using the same
procedure.
5
Note:DO NOT use abrasive tissues or wipers as these will scratch the tip.
NEVER use solvents (ie. alcohol or acetone) on the tip or to clean
molded handle scanners since these may damage the finish.
Maintenance and Troubleshooting
5–1
Page 44
5.3 Inspection
Cords And Connectors
The scanner cord and the “Y” interface cable should be inspected
periodically for wear and other signs of damage. A badly worn cord may
interfere with the proper operation of the unit and may require replacement
of the scanner. Damaged scanner cables and/or connector(s) can be
repaired/replaced by Welch Allyn.
Scanner Case
The scanner enclosure should also be routinely examined for signs of
damage. A badly dented enclosure may contact internal components and
result in damage to or malfunction of the unit.
5.4 Troubleshooting
If the scanner fails to operate properly, perform the following checks:
1)Check the “Y” interface cable connection(s) to make sure the scanner
is properly attached to the host P.C.
2)If the unit has been programmed to “beep” on Reset, did it “beep”?
Failure to beep indicates a possible internal wand problem. Contact
Welch Allyn for assistance (refer to page 5–4).
3)Confirm that the scanner has been programmed for the correct
terminal.
4)Confirm that the scanner is properly configured for the bar code
symbology(s).
5)Inspect the quality of the bar code symbols that are being used.
Symbols that are of a low contrast, scratched or otherwise defaced
may cause scanning problems. T o verify scanner operation, test the
system with a high quality bar code symbol. As an additional check,
verify the quality of bar code symbols with a bar code verifier such as the
Quick Check, available from Welch Allyn.
5–2
Maintenance and Troubleshooting
Page 45
6)Check the condition of the scanner tip. If the tip is scratched, the
scanner may not read properly. If the tip is broken or cracked, the
optics may also become damaged by dust or other foreign matter.
Should either of these conditions be present, replace the scanner tip.
The tip can be removed by inserting a thin coin into the tip locking ring
and prying it off the end of the scanner.
Do not touch or make contact with the exposed lens surface as permanent
damage to the scanner optics may result.
Welch Allyn recommends keeping a supply of spare tips on hand. If
replacing the tip does not correct the scanning problem, it may be
necessary to replace the entire wand unit.
Note:Other than the replaceable tip, the wand scanner contains no user
serviceable parts and, therefore, the scanner case should not be
opened.
Opening the scanner voids the warranty.
If proper wand operation cannot be obtained after performing these checks,
factory service may be required.

A.6 Bar Code Symbol Specifications
All bar code symbols should satisfy the appropriate AIM Uniform
Symbology Specification.
Background Substrate
The bar code symbol should be printed on material which is reflective and
has a matte (not glossy) finish. A background diffuse reflectance of at least
70% to 80% is desirable for optimum contrast.
Ink Color and Type
The inked bars should not exceed 25% reflectance at the wavelength which
is being used for reading, whether printed with black ink or colored ink.
The reflectance value should not vary more than 5% within the same
character. The type of ink should be compatible with the type of radiation
in the optical scanner. If a scanner with an infrared radiation source is
being used, the ink in the code must be IR absorptive (typically carbon
based). Otherwise, the IR would “see through” the ink and be reflected to
the sensor as if from a completely white surface.
Voids and Specks
The code should be printed clearly, free of voids, specks, blemishes and
lines which could “fool” the scanner. Specks or blemishes in the white
spaces, or false or missing bar sections could be interpreted by the reading
equipment as part of the code. Generally, the width of such flaws is more
serious than the height. Code symbols should be rejected if these defects
are present.
Definition
The bars in the bar code symbol should be well defined. Their edges
should not be rough or fuzzy, so that the bars and spaces have the proper
widths intended for the bar code symbology used. Since a scanner’s
aperture and resolution are chosen to comply with these widths, definition
should be sharp and consistent.
Technical Specifications
A–5
Page 54
Contrast
Background reflectance (that of the substrate on which the codes are
printed) should always provide a good contrast relative to the ink
reflectance (that of the code bars). The difference between the two should
be at least 37.5% at the wavelength used for reading.
Tolerance
The ratio of the widths of bars and spaces in a bar code symbol must
conform to the appropriate AIM bar code specifications and can cause
problems if not correct throughout the bar code. Problems can occur when
bar edges are smeared or rough, or when they exhibit voids.
