PRODUCT DESCRIPTION

The new DS1500 industrial laser scanner is the combination of extremely compact
dimension and powerful high-speed reading capabilities, which makes the scanner
ideal for OEM integration projects.
DS1500 miniaturization allows an easy OEM integration in pieces of equipment and
automatic machinery. Concurrently, the high scan rate and code reconstruction
software effectively address demanding applications.
The availability of ACB™ (Advanced Code Builder) embedded reconstruction
software algorithm allows effective decoding of damaged or normally unreadable
codes due to a high tilt angle.
DS1500 installation and configuration is easy and simple thanks to the compact size
and to the new test operating mode with bar graph. Test Mode is activated by means
of a key on the scanner (no external PC is required), and the bar graph shows real
time scan rate, which is of great help for installation and reading performance
monitoring purposes.
DS1500 operates at a speed up to 1200scan/s. Furthermore, the scanner motor can
be switched ON and OFF via software command while keeping the unit powered.
This allows a prompt restore of full operation and drastically increases the product
life.
DS1500 is equipped with a software selectable serial link (RS232 or RS485) thus
minimizing the number of models needed to fit all possible applications.
The main DS1500 features are:
•

Extremely compact dimensions and light weight

•

High scan rate software programmable (up to 1200 scan/s)

•

ACB (Advanced Code Builder) code reconstruction software embedded

•

Ease of use thanks to Test Mode with reading performance bar graph

•

POSITIONING

The DS1500 scanner is able to decode moving barcode labels at a variety of angles,
however significant angular distortion may degrade reading performance.
When mounting the DS1500 take into consideration these three ideal label position
angles: Pitch 0°, Skew 15° to 30° and Tilt 0°.
Follow the suggestions for the best orientation:
The Pitch angle is represented by the value P in Figure 15. Position the reader in
order to minimize the Pitch angle.
P

Figure 15 - Pitch Angle

The Skew angle is represented by the value S in Figure 16. Position the reader to
assure at least 10° for the Skew angle. This avoids the direct reflection of the laser
light emitted by the DS1500.

Figure 16 - Skew Angle

DS1500

The Tilt angle is represented by the value T in Figure 17. Position the reader in order
to minimize the Tilt angle.
T

Figure 17 - Tilt Angle

By using the ACB (Advanced Code Builder) software parameter, the tilt angle is less
critical and can be decoded even if the scan line doesn’t cross the entire code.
See par. 3.1 or the Help On Line for details.

TYPICAL LAYOUTS

The following typical layouts refer to system hardware configurations. Dotted lines in
the figures refer to optional hardware configurations within the particular layout.
These layouts also require the correct setup of the software configuration
parameters. Complete software configuration procedures can be found in the Guide
To Rapid Configuration in the WinHost Help On Line.

2.6.1

Point-to-Point

In this layout the data is transmitted to the Host on the main serial interface. Host
Mode programming can be accomplished either through the main interface or the
Auxiliary interface.
In Local Echo communication mode, data is transmitted on the RS232 auxiliary
interface independently from the main interface selection.
When On-Line Operating mode is used, the scanner is activated by an External
Trigger (photoelectric sensor) when the object enters its reading zone.

Pass-Through

Pass-through mode allows two or more devices to be connected to a single external
serial interface.
Each DS1500 transmits the messages received by the Auxiliary interface onto the
Main interface. All messages will be passed through this chain to the host.
When On-Line Operating mode is used, the scanner is activated by an External
Trigger (photoelectric sensor) when the object enters its reading zone.
The Main and Auxiliary ports are connected as shown in the figure below:

2.6.3

RS232 Master/Slave

The RS232 master/slave connection is used to collect data from several scanners to
build either a multi-point or a multi-sided reading system; there can be one master and
up to 9 slaves connected together.
The Slave scanners use RS232 only on the main and auxiliary serial interfaces. Each
slave DS1500 transmits the messages received by the auxiliary interface onto the main
interface. All messages will be passed through this chain to the Master.
The Master scanner is connected to the Host on the main serial interface. The main
interface type for the master scanner is RS232.
There is a single reading phase and a single message from the master scanner to the
Host computer.
Either On-Line or Serial On-Line Operating modes can be used in this layout.
When On-Line Operating mode is used, the external trigger signal is unique to
the system, however it is not necessary to bring the external trigger signal to the
Slave scanners.
The main and auxiliary ports are connected as shown in the figure below.

READING FEATURES
ADVANCED CODE BUILDER (ACB)

In addition to linear reading, the Advanced Code Builder (ACB) allows code reading
by “stitching” together two partial reads of it. ACB is not as powerful as Advanced
Code Reconstruction due to limits on tilt angle, speed and Multi-label function; but it
is effective in the case of close-to-linear, small height codes, damaged codes, or poor
print quality codes.
ACB is used to read a code label when the scan line does not cross the label along
its entire length (excessive tilt angle).

Linear Reading

ACB Reading

Linear Reading

ACB Reading

ACB reads two fragments of a label containing a start or a stop character and a
number of digits, and puts them together to build the complete label.
ACB also has an intrinsic ability to increase the reading percentage of damaged
codes as in the examples below:

ACB Readable

Not ACB Readable

READING FEATURES

ACB Readable

ACB is disabled by default but can be enabled for the following code types:
•
•
•

3.1.1

Code 25 Interleaved
Code 39 Family
Codabar

•
•
•

Code 128/EAN128
EAN/UPC (without ADD-Ons)
Code 93

Important ACB Reading Conditions

•

Do not use ACB for omni-directional reading stations.

•

ACB can be activated for each symbology independently from the others.

•

ACB requires that the code be in movement with respect to the scanner.

•

ACB requires fixed length barcode reading.

•

The codes read with ACB enabled must pass in front of the scanner one at a
time.

Not valid for ACB

Valid for ACB

•

Code concatenation and ACB are not compatible and therefore cannot be
enabled simultaneously on the same code.

•

For correct operation, ACB requires at least 5 scans for each of the two
fragments

DS1500

3.1.2

Tilt Angle Improvement with ACB

ACB allows barcode reading with an increased tilt angle. The tilt angle depends upon
the code aspect ratio defined as H/L according to the table below:
L

LINEAR CODE READING

The number of scans performed on the code by the DS1500 and therefore the
decoding capability is influenced by the following parameters:
•
•
•
•

number of scans per second
code motion speed
label dimensions
scan direction with respect to code motion

At least 5 scans during the code passage should be allowed to ensure a successful
read.

READING FEATURES

3.2.1

Step-Ladder Mode

If scanning is perpendicular to the code motion direction (Figure 23), the number of
effective scans performed by the reader is given by the following formula:
SN = [(LH/LS) * SS] – 2

Where:

SN = number of effective scans
LH = label height (in mm)
LS = label movement speed
in (mm/s)
SS = number of scans per second
Direction of code
movement at LS speed

Figure 23 - "Step-Ladder" Scanning Mode

For example, the DS1500 (1200 scans/sec.) for a 20 mm high code moving at 1200
mm/s performs:
[(20/1200) * 1200] - 2 = 18 effective scans.

DS1500

3.2.2

Picket-Fence Mode

If scanning is parallel to the code motion, the number of effective scans is given by
the following formula:
SN = [((FW-LW)/LS) * SS] -2

Where: SN

GLOSSARY
ACB (Advanced Code Builder)
Advanced Code Builder (ACB) allows code reading by “stitching” together two partial
reads of it. ACB is effective in reading codes positioned close-to-linear, small height
codes, damaged codes, or poor print quality codes. See par. 3.1
Aperture
Term used on the required CDRH warning labels to describe the laser exit window.
Barcode
A pattern of variable-width bars and spaces which represents numeric or
alphanumeric data in machine-readable form. The general format of a barcode
symbol consists of a leading margin, start character, data or message character,
check character (if any), stop character, and trailing margin. Within this framework,
each recognizable symbology uses its own unique format.
Barcode Label
A label that carries a barcode and can be affixed to an article.
Baud Rate
A unit used to measure communications speed or data transfer rate.
CDRH (Center for Devices and Radiological Health)
This organization (a service of the Food and Drug Administration) is responsible for
the safety regulations governing acceptable limitations on electronic radiation from
laser devices. Datalogic devices are in compliance with the CDRH regulations.
Code Positioning
Variation in code placement that affects the ability of a scanner to read a code. The
terms Pitch, Skew, and Tilt deal with the angular variations of code positioning in the
X, Y and Z axes. See pars. 2.2.1 and 2.5. Variations in code placement affect the
pulse width and therefore the decoding of the code. Pulse width is defined as a
change from the leading edge of a bar or space to the trailing edge of a bar or space
over time. Pulse width is also referred to as a transition. Tilt, pitch, and skew impact
the pulse width of the code.
Decode
The process of translating a barcode into data characters using a specific set of rules
for each symbology.
Decoder
As part of a barcode reading system, the electronic package which receives the
signals from the scanner, performs the algorithm to interpret the signals into

meaningful data and provides the interface to other devices. The decoder is normally
integrated into the scanner.
EAN
European Article Number System. The international standard barcode for retail food
packages.
EEPROM
Electrically Erasable Programmable Read-Only Memory. An on-board non-volatile
memory chip.
Full Duplex
Simultaneous, two-way, independent transmission in both directions.
Half Duplex
Transmission in either direction, but not simultaneously.
Host
A computer that serves other terminals in a network, providing services such as
network control, database access, special programs, supervisory programs, or
programming languages.
Interface
A shared boundary defined by common physical interconnection characteristics,
signal characteristics and meanings of interchanged signals.
LED (Light Emitting Diode)
A low power electronic device that can serve as a visible or near infrared light source
when voltage is applied continuously or in pulses. It is commonly used as an
indicator light and uses less power than an incandescent light bulb but more than a
Liquid Crystal Display (LCD). LEDs have extremely long lifetimes when properly
operated.
Multidrop Line
A single communications circuit that interconnects many stations, each of which
contains terminal devices. See RS485.
Parameter
A value that you specify to a program. Typically parameters are set to configure a
device to have particular operating characteristics.
Picket-Fence Orientation
When the barcode’s bars are positioned vertically on the product, causing them to
appear as a picket fence. The first bar will enter the scan window first. See par. 3.2.2.

Pitch
Rotation of a code pattern about the X-axis. The normal distance between center line
or adjacent characters. See pars. 2.2.1 and 2.5.
Position
The position of a scanner or light source in relation to the target of a receiving
element.
Protocol
A formal set of conventions governing the formatting and relative timing of message
exchange between two communicating systems.
Raster
The process of projecting the laser beam at varied angles spaced evenly from each
other. Typically, the mirrored rotor surfaces are angled to create multiple scan lines
instead of a single beam.
Resolution
The narrowest element dimension which can be distinguished by a particular reading
device or printed with a particular device or method.
RS232
Interface between data terminal equipment and data communication equipment
employing serial binary data interchange.
RS485
Interface that specifies the electrical characteristics of generators and receivers for
use in balanced digital multipoint systems such as on a Multidrop line.
Scanner
A device that examines a printed pattern (barcode) and either passes the
uninterpreted data to a decoder or decodes the data and passes it onto the Host
system.
Serial Port
An I/O port used to connect a scanner to your computer, generally identifiable by a 9pin or 25-pin connector.
Signal
An impulse or fluctuating electrical quantity (i.e.: a voltage or current) the variations of
which represent changes in information.
Skew
Rotation about the Y-axis. Rotational deviation from correct horizontal and vertical
orientation; may apply to single character, line or entire encoded item. See pars.
2.2.1 and 2.5.

Step-Ladder orientation
When the barcode’s bars are positioned horizontally on the product, causing them to
appear as a ladder. The ends of all bars will enter the scan window first. See par.
3.2.1.
Symbol
A combination of characters including start/stop and checksum characters, as
required, that form a complete scannable barcode.
Tilt
Rotation around the Z axis. Used to describe the position of the barcode with respect
to the laser scan line. See pars. 2.5 and 3.1.
Trigger Signal
A signal, typically provided by a photoelectric sensor or proximity switch, which
informs the scanner of the presence of an object within its reading zone.
UPC
Acronym for Universal Product Code. The standard barcode type for retail food
packaging in the United States.
Visible Laser Diode
A light source used in scanners to illuminate the barcode symbol. Generates visible
red light at wavelengths between 630 and 680 nm.
