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.
1.2 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.

1–2 Introduction to the SCANTEAM 2380
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.
Figure 1.1 SCANTEAM 2380 Keyboard Wedge Connection
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.

Introduction to the SCANTEAM 2380
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.

1–4 Introduction to the SCANTEAM 2380
1.4 Wand Models
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.
For additional assistance in selecting the SCANTEAM 2380 decoded
output scanner keyboard wedge best suited to your bar code application,

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.
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.

2–2 Operational Description
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.
2.5.1 Scanner Illumination Source
Wand type scanners are equipped with a visible red (660nm) source.

2–3
Operational Description
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.
2.5.2 Scanning 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.

2–4 Operational Description
2.5.3 Depth 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°).
2.5.4 Scanning 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).
2.5.5 High 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.

2–5
Operational Description
2.5.6 Print 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 (Rbmax) – Min (Rsmin)
where: Rsmin = Minimum Space Reflectance
Rbmax = Maximum Bar Reflectance
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.

2–6 Operational Description
