1 INTRODUCTION
1.1 LYNX™ D DESCRIPTION
The Lynx™ D Hand-Held Reader packs a lot of performance into an attractive,
rugged, hand-held device. It operates in commercial and industrial environments as
well as the front office.
Omni-directional
Operating
Decoding
And
Imaging
FLASH MEMORY
1.2 PACKAGE CONTENTS
The following parts are included in the Lynx™ D package contents:
• Lynx™ D Hand-Held Reader
• CD-ROM containing the Lynx™ D Configuration Tools software and Lynx™ D
Reference Manual
• Lynx™ D User’s Manual
You may want to save your packing material in case you need to ship the reader at
some later time.
To read a symbol or capture an image, you simply aim the
reader and pull the trigger. Since Lynx™ D is a powerful
omni-directional reader, the orientation of the symbol is not
important.
Thanks to powerful algorithms, Lynx™ D reliably decodes all
major 1D (linear) barcodes, 2D stacked codes (such as
PDF417), 2D matrix symbols (such as DataMatrix), postal codes
(such as POSTNET, PLANET). The data stream — acquired
from decoding a symbol — is rapidly sent to the host. The
reader is immediately available to read another symbol.
Lynx™ D can also function as a camera by capturing images
of labels, signatures, and other items.
Flash technology allows to upgrade the Lynx™ D reader as
new symbologies are supported or as improved decoding
algorithms become available.

1.3 CONFIGURATION METHODS
1.3.1 Reading Configuration Codes
This manual can be used for complete setup and configuration. If you wish to change
the default settings, you can configure the Lynx™ D reader by reading the
programming code symbols in this manual. Configuration commands and their
relative arguments are read individually using the symbols in this manual. See
Appendix D.
1.3.2 Using VisualSetup
The Datalogic VisualSetup program, available on the CD-ROM provided, allows
programming the reader by selecting configuration commands or printing them
through a user-friendly graphical interface running on the PC. These commands are
sent to the reader over the current communication interface; or they can be printed to
be read.
1.3.3 Sending Configuration Strings from Host
An alternative configuration method is provided in Appendix A using the RS232 or
USB COM interface. This method is particularly useful when many devices need to
be configured with the same settings. Batch files containing the desired parameter
settings can be prepared to configure devices quickly and easily.

2 USING LYNX™ D
2.1 AIMING SYSTEM
The Lynx™ D reader uses an intelligent aiming system similar to those on cameras.
By partially pulling the trigger, the aiming system indicates a field of view to be
positioned over the code:
Figure 1 - Aiming System
When you pull the trigger completely a red beam illuminates the code. If the aiming
system is centered and the entire symbology is within the aiming system, you will get
a good read. The field of view changes size as you move the reader closer or farther
away from the code.

Figure 2 - Relative Size and Location of Aiming System Pattern

LYNX™ D
The field of view indicated by the aiming system will be smaller when the Lynx™ D is
closer to the code and larger when it is farther from the code. Symbologies with
smaller bars or elements (mil size) should be read closer to the unit. Symbologies
with larger bars or elements (mil size) should be read farther from the unit. (See
chapter 8 for further details).
2.2 NORMAL OPERATION
Lynx™ D normally functions by capturing and decoding codes.
Point the reader at the target and pull the trigger partially to enable the aiming
system. Then, pull it completely to capture and decode the image. The reader will
repeatedly flash until the symbol is decoded or timeout is reached. In between the
flashes of the reader, the aiming system keeps on showing the field of view on the
target (see Figure 2
As you are reading code symbols, adjust the distance at which you are holding the
reader.
NOTE
).
The Lynx™ D hand-held reader aiming system is designed for
general reading and decoding of 1D and 2D symbols. Some variation
in reading distance will occur due to narrow bar width and other
factors.
If reading codes positioned on reflective surfaces, it may be

a
In order to capture an image, the user should read a Capture Image code (see
page 72), then point at the image subject and pull the trigger. This way, the image
will be captured and sent to the host PC. Lynx™ D then returns to normal operation.

You can use the aiming system to position the reader from the object (ensure the
reader is about centered over the target). Adjust the distance at which you are
holding the reader (see Figure 2).

2.3.2 Advanced Configuration Parameters
An image portion (Window), instead of an entire image, can be captured. This
parameter is generally used for particular fixed reading position applications.

480
Y
An Image Window may either be as large as the image itself or smaller (10 x 10
pixels minimum), and is defined by its origin (the coordinate X
), its width (number
0, Y0
of pixels along the X Axis) and its height (number of pixels along the Y Axis).
By default, for all Image Presets, the window has its origin coordinates equal to zero,
its width equal to 640 pixels and its height to 480 pixels.
It is possible to perform Zooming of the image. The zoom range varies from 20% up
to 200% in steps of 20%, so ten different settings are available. Default is 100% (no
zoom).
In addition to Windowing and Zoom you can adjust Brightness and Contrast levels.
Brightness Adjustment is available in the range from –100% up to 100%, in steps of
1%. Positive values shift the luminance up so that the image will result brighter.
Default value is 0%, meaning that no brightness adjustment is performed.

The same range of values (–100% up to 100%, in steps of 1%) is available for
Contrast Adjustment. Positive values will increase the contrast, so that dark and
bright objects inside the image will be better distinguishable. Default value is 0%,
which means that no contrast adjustment is performed.
You can set the Image Color Depth by selecting 256 gray levels (default), 16 gray
levels, or 2 gray levels. Higher color depths yield larger image files. This option is
ignored if the JPEG format is selected,(256 gray levels only).

2.4 AUTOSCANNING
2.4.1 Normal Mode
Lynx™ D provides an autoscan command (see page 70), which when enabled,
causes the reader to scan continuously and to monitor the central zone of its reading
area. In this way, Lynx™ D is ready to capture any image (containing a potential
code) positioned on a
The aiming system can be enabled to indicate the reading area of the potential code
to be captured. The illumination system can also be enabled when the ambient light
conditions are not sufficient to autodetect the potential code to be captured;
furthermore, the illumination system increases in intensity for an instant when
capturing and decoding an image. A safety time may be defined to prevent Lynx™ D
from reading the same code repeatedly.
If the decoding is completed successfully, the reader starts monitoring the reading
area again. In case of decoding failure, Lynx™ D keeps on decoding until a potential
code is present in the central zone of the reading area.
uniform background.
2.4.2 Pattern Mode
The Autoscan pattern mode is particularly advised when reading barcodes positioned
non-uniform background. In these cases Lynx™ D may perceive some elements
on a
of the background as barcodes and start the decoding. To avoid this undesired
effect, the Autoscan Pattern Code is placed in the Lynx™ D reading area which
prevents decoding. Using this code as the background, code reading takes place
normally by presenting desired codes to be read over the Pattern Code. Between
each code read, the Pattern Code must be represented to Lynx™ D.
The Pattern Code can be printed from the file of the manual (Appendix D) available
on the CD-ROM.
In case of low ambient light conditions, Lynx™ D automatically activates the
illumination system. If desired, the illumination system can be enabled so that it is
always active.

2.5 CAMERA CONTROL
Exposure and Calibration
Two different control modes are available for managing the camera: automatic mode
and fixed mode.
The automatic mode provides three different options to get the best tuning of the
image to be captured:
Automatic based on entire image: camera control mode based on the analysis of
the whole image. This mode works well in most standard applications. It is the
default setting.
-
Automatic based on central image: camera control mode based on the analysis
of a restricted area positioned in the central zone of the image. This mode is
suggested when reading small codes positioned in a dark and extensive
background.
-
Automatic for highly reflective surfaces: camera control mode allowing to read
codes on highly reflective surfaces. This mode is suggested, for example, when
reading codes positioned on plastic or metal surfaces.
The fixed mode is particularly suggested for expert users. It requires a camera
calibration to adjust the acquisition parameters to the ambient light conditions. The
defined values will always be used when working with a fixed exposure.
These values are permanently saved in the reader memory.
Refer to page 50 for configuration codes.
Aiming System Calibration
The factory-defined Lynx™ D aiming system is already correctly and precisely
calibrated to the Lynx™ D focus distance and therefore works for the most typical
applications. However, it is possible to modify the aiming system precision for the
following condition:
when a

Lynx™ D432E.

calibration.

2.6 DEFINING DATA FORMATTING
The string of a decoded code to be sent to the host may be formatted as follows:
• defining simple data formatting (see page 40);
• defining advanced data formatting giving complete flexibility in changing the
format of data (see par. 4.3).
When both simple and advanced data formatting are selected the info is processed in
the following order:
1. the string of the decoded code is processed according to the advanced
formatting rules;
2. the resulting string is processed according to the selection type rules of the
simple data formatting;
3. character substitution is performed on the resulting string;
4. character deletion is performed on the resulting string;
5. code concatenation is performed;
6. code ID is attached to the resulting string;
7. global headers and terminators are attached to the resulting string;
The codes to be sent to the host may also be selected or ordered depending on the
following two conditions:
• one code per scan: Lynx™ D sends the code being closest to the image center.
If the "Central Code Transmission" command is enabled, only the code
containing the image center will be transmitted (see page 69);
• all codes per scan: the codes to be sent to the host may be ordered either by
length or by symbology starting from the code being closest to the image center
(see page 69). When enabling both these criteria, codes belonging to the same
symbology are sent to the host depending on their length.

LYNX™ D
2.6.1 Concatenation
It is possible to concatenate up to 4 different codes, set their length and enable the
intercode delay between them (the intercode delay is set in the specific interface
parameters, see page 25, 27 and 32). When enabling the delay one or more global
headers and terminators are added to the decoded data. The concatenation
procedure may occur in different ways depending on the number of codes to be
decoded per image:
One Code Per Scan
• If the code resulting from the single decoding of an image belongs to one of the
code families to be concatenated, it is saved to the Lynx™ D memory waiting for
other codes to complete the concatenation.
• If the code belongs to the same family of a code previously saved, it overwrites
the old one.
• If the code resulting from the decoding does not belong to one of the code
families to be concatenated, it causes the concatenation failure and clears the
temporary memory. If the "Concatenation Failure Transmission" command is set
to "Tx codes causing failure" (see page 48), this code will be sent in the output
message.
All Codes Per Scan
• All codes resulting from the decoding of an image and belonging to one of the
families to be concatenated are saved to the Lynx™ D memory waiting for other
codes to complete the concatenation.
• If one or more codes resulting from the decoding belong to the same family of
codes previously saved, they overwrite the old ones.
• When the image contains no code to be concatenated, the concatenation fails
and the reader temporary memory is cleared. If the "Concatenation Failure
Transmission" command is set to "Tx codes causing failure" (see page 48), the
codes causing the concatenation failure will be sent in the output message.
