1 INTRODUCTION
1.1 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
Reads all popular barcode symbologies
5 operating modes available to suit most common application requirements
Code verifier option embedded
Completely configurable via serial interface (WinHost™ configuration SW)
Serial communication interfaces software selectable (RS232, RS485)
Low power consumption

An additional 15 ms (typical) delay can be implemented through a dedicated software parameter (refer to WinHost Help On Line).
2.3.5 Outputs
Two general purpose outputs are available. open collector configurations. The following pins are present on the 15-pin connector of the scanner:
Pin Name Function
7 OUT1+ output 1 +
14 OUT2+ output 2 +
5 GND output reference
The meaning of the two outputs OUT1 and OUT2 can be defined by the user (No Read, Right, Wrong, or a combination). Refer to the WinHost Help On Line.
By default, OUT1 is associated with the No Read event, which activates when the code signaled by the external trigger is not decoded, and OUT2 is associated with the Right event, which activates when the code is correctly decoded.
These outputs are both level and pulse configurable.

2.5 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.
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.

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.

2.6 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.

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.
On-Line or Serial On-Line Operating modes can be used in this layout.
Either
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.

3 READING FEATURES

3.1 ADVANCED CODE BUILDER (ACB)

In addition to linear reading, the 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).
Advanced Code Builder (ACB) allows code reading
Linear 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
28
READING FEATURES

ACB Readable
ACB is disabled by default but can be enabled for the following code types:
Code 25 Interleaved Code 128/EAN128
Code 39 Family EAN/UPC (without ADD-Ons)
Codabar Code 93

3.1.1 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
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
Valid for ACB

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:

0.25 14° 23°
0.125 7° 11°

3.2 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.
30
READING FEATURES
3
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
LH
DS1500
Laser beam
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.
31
3
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 = number of effective scans FW = reading field width (in mm)
LW = label width (in mm)
LS = label movement speed
(in mm/s)
SS = scans per second
Direction of code movement at LS speed

For example, for a 60 mm wide code moving in a point where the reading field is 100 mm wide at a 1500 mm/s speed, the DS1500 (1200 scans per sec.), performs:
[((100-60)/1500) * 1200] - 2 = 30 effective scans

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
47
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.
48
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.
49
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.
