General features -

2.1

1 GENERAL FEATURES

1.1 INTRODUCTION

The DS8100 scanner is a barcode reader complete with decoder des igned to
provide an innovative and high performance solution in omnidirectional
reading applications by combining the following advanc ed technologies with
Datalogic’s solid experience in the material handling sector.

ACR™

Advanced Code Reconstruction technology allows the reading of low aspect
ratio labels placed anywhere on a parcel and enhances the readability of
poorly printed or damaged codes.

CD SQUARE™

CD SQUARE™ provides useful information on label position and object
shape elaborated during the barcode reading phase. This innovative
technology identifies the area in which the code is located and measures the
code distance from the scanner.

PACKTRACK™

PackTrack ™ is a Datalogic patented parcel trac king system which im proves
the reading features in omnidirectional stations. In particular, PackTrack™
manages 6-sided reading systems when it is im possible to detect the real
position of the code on the parcel, thus overcoming the need for external
accessories essential in traditional tracking systems.

ASTRA™

Automatically SwiTched Reading Area™ is the new Datalogic technology
based on a multi-laser architec ture and a fixed mounted optic system which
concentrates the multiple laser emissions in a single laser beam. As each
laser emitter is focused on a specific range of the reading area, a
sophisticated electronic controller select s the best focused laser emitter with

DS8100 DATALOGIC

2.2

- General features

respect to the code to read. This allows the reading of medium- high density
codes in a large reading area on very fast conveyors.

TBS™

Twin Beam System™ improves the reading of c odes covered by plastic film
or wrapping material. The optic architec ture is able to c hange the laser diode
path and to adapt the beam’s skew angle on the code to read. This makes
the scanner insensitive to direct reflections and to the bars’ distortion caused
by the plastic film.

Single-scanner and Multi-scanner Applications

DS8100 Serial Interface version is provided with two standard interfaces
allowing easy use and connection and is therefore suitable f or single-reader
applications.

DS8100 Bus Interface version is particularly suited for multi-scanner
applications. It is provided with a Lonworks network for connections with
other DS8100s and with an SC8000 unit which performs real time data
collection and control of the reading station.

Flexibility

The high frequency laser diode modulation system guarantees complete
immunity to ambient light and allows installation of the DS8100 in any
working area.

The DS8100 Serial Interface is easy configurable by means of the W indows­based user-friendly Winhost utility program provided on diskette.
It can also be configured from a Host PC through the Hos t Mode procedure
or using the built-in keypad through the Keyboard Mode procedure.

2.5.2 Power Supply

The supply voltage for correct operation of the scanner must be between 20
and 30 VDC.

The max. power consumption is 30 W.
The power supply unit (optional) supplies the power necessary for the

DS8100 and allows mains power to be used.
A security system allows the laser to activate only once the motor has

reached the correct rotational speed; consequently, the laser beam is
generated after a slight delay from the power on of the scanner.

The switch (Figure A,

17

) on the connector panel turns off power to both the

motor and the laser beams.
During power up of the scanner there is a cur rent peak of about 3A caused

by the motor startup.

2.5.3 Main Serial Interface

The main serial interface of the DS8100 Serial Interface version is
compatible with the following electrical standards:

RS232
RS485 full-duplex
RS485 half-duplex
20 mA current loop

The configuration param eters of the selected inter face can be defined using
one of the programming methods available. For this procedure refer to the
WINHOST Help On Line shipped on the diskette.

The connections regarding the interface selected are described in the
following sections.

NOTE

The signals relative to the selected interface are only available
on the Main Interface connector if the jumper ins ide the sc anner
is correctly positioned. Refer to par. 2.3.1 for further details.

RS485 Half-Duplex Interface

The RS485 half-duplex (3 wires + shield) interface is used for polled
communication protocols. It can be used for Multidrop connections in a
master/slave layout or with a Datalogic Multiplexer, (see par. 2.7.3, 2.7.4 and

2.7.5).
Device connection to the Multidrop line can be controlled externally through

the RS485CNTR line. For example, it may be necessary to disconnect a
scanner from the line if the device is dam aged or the line is overloaded. To
do this, apply a voltage from 20 to 30 Vdc to the RS485CNTR signal using
the same GND of the power supply as a reference.

2.5.5 Inputs

The inputs of the scanner are on the

Input Signal A and B connectors

on

the body of the DS8100 (Figure A,

13

These inputs are called ENC, PS1 and PS2.
ENC is the Encoder input. In PackTrack™ operating mode, it detects the

conveyor speed.

DS8100 DATALOGIC

2.18

- Installation — DS8100 Serial I nterface

PS1 is the main presence sensor (external trigger). When ac tive, this input
tells the scanner to scan for a c ode and that decoding can take plac e. The
yellow LED (Figure A,

4

) indicates that PS1 is active.

PS2 can be used as the stop signal for the reading phase.
All inputs are optocoupled and driven by a constant current generator; the

command signal is filtered through an anti-disturbance circuit which
generates a delay of about 5 ms for PS1 and PS2 and 500 µs for ENC.

A D.C. output voltage, the same as that powering the DS8100, is present
between pins 1 and 2. This may be used to power external devices: electrical
isolation between the scanner and external devices is lost in this case.

The

No Read

output activates when a code signalled by the presence sensor

is not decoded.
The

Right

output is used to signal the presence of a right code, thus a good

decode condition.
All outputs are level or pulse program mable: a 50 ms pulse is generated in

the second case. Further programming information is supplied in the
WINHOST Help File.

These outputs are created using optoisolated Dar lington drivers and supply
both the collector and emitter in output, allowing both loads referenced to
ground and to the power supply to be driven.

The electrical features are given below:
Collector-emitter voltage 30 V Max.

Collector current 130 mA Max (pulsed).

however significant angular distortion may degrade reading performance.

When mounting the DS8100 take into consideration these three ideal label
position angles:

Pitch 0°, Skew 0° to 45° and Tilt 0°

.

Follow the suggestions for the best orientation:

The data is also transmitted on the Auxiliary interface (if configured for
Standard communication mode), as well as on the Main interface.

The

auxiliary interface uses RS232 for this layout.
Host Mode programming can be accomplished either thr ough the Main or the

Auxiliary interface.

2.7.2 Pass Through

Pass Through Mode allows two or more devic es to be connected to a single
external serial interface. The DS8100 tr ans mits the messages rec eived by its
auxiliary interface (RS232 only) onto its main interface.

In this configuration a series of s canners can be connected together using
RS232 on the main interface and all messages will be passed through this
chain to the host.

The reading phase of each scanner is independent from the others in a Pas s
Through chain.

When On-Line Operating mode is used, the scanner is
activated by an External Trigger (presence sensor) when the object enter s its
reading zone.

Applications can be implem ented to connect a device such as a hand-held
reader to the Auxiliary port for manual code reading capability.

2.7.3 RS485 Master/Slave

The RS485 Master/Slave connection is used to collect data from several
scanners to build either an omni-directional or multi-sided reading system;
there can be one Master and up to 8 Slaves connected together.

The Master and Slave scanners are connected together using RS485 half­duplex on the auxiliary serial interface.

The Master scanner is also connected to either a Host or a Multiplexer on the
main serial interface. T he possible main inter face type selections are RS232
or RS485 full-duplex for Host connections or RS485 half-duplex for
Multiplexer connections (see “Main Interface Selection” in par. 2.3.1).

For the Slave scanners the Multidrop Address Selection can be m ade using
the DIP switch. The addresses m ust be consec utive and not inc lude zero for
hardware configuration, or be selected in software (in this case the DIP
switch address must be zero for each Slave). See par. 2.3.2.

NOTE

The main serial port of the Slave scanners can be used
for configuration. The termination r esistors of the RS485
bus must not be installed.

Single P.S.

The P.S. signal is unique to the system; there is a single reading phase and
a single message from the master scanner to the Host.

3.4.1 Power Supply

The supply voltage for correct operation of the scanner must be between 20
and 30 VDC.

The max. power consumption is 30 W.
The power block (optional), supplies the power necessary for the DS8100

and allows mains power to be used.
A security system allows the laser to activate only once the motor has

reached the correct rotational speed; consequently, the laser beam is
generated after a slight delay from the power on of the scanner.

The switch (Figure B,

) on the connector panel turns off power to both the

motor and the laser beams.
During power up of the scanner there is a cur rent peak of about 3A caused

by the motor startup.

PSAux can be used in special applications.
All inputs are optocoupled and driven by a constant current generator; the

command signal is filtered through an anti-disturbance circuit which
generates a delay of about 5 ms for PS and PSAux and 500 µs for ENC.

3.6 Typical Layout

The scanner is generally activated by a photoelectric sensor used as a code
presence sensor when the object enters its reading zone.

The following figures show a typical layout for DS8100 Bus Interface.
A Lonworks cable provides a communic ation line (branch) between up to 4

scanners and an SC8000 unit. The last scanner on the line requires a
Termination connector. Up to 4 br anches of this type can be connected to a
single SC8000. The allowed maximum length of the cable is 65 m.

External devices such as a presence sensor , an encoder and the supply unit
are all connected to the SC8000, which collects all signals driving them to all
scanners.

The SC8000 is also connected to a Host.

4 READING FEATURES

4.1 ADVANCED CODE RECONSTRUCTION

The traditional way of barcode reading could be called "Linear Reading". In
this case, the laser beam cros ses the barcode symbol from its beginning to
its end as shown in Figure 4.1.

Laser Beam

Figure 4.1 - Linear reading

In "Advanced Code Reconstruction" mode, it is no longer necessary for the
laser beam to cross the label from the start to the end. W ith just a set of
partial scans on the label (obtained using the motion of the label itself), the
DS8100 is able to "reconstruct" the barcode. A typical set of partial scans is
shown in Figure 4.2.

Code Direction

Figure 4.2 - Partial scans

None of the partial scans contains the whole label. The decoder aligns each
partial scan correctly and combines them in order to obtain the entire code.

The alignment is performed by calculating the time difference from one
partial scan to another using a reference code element.

4.1.1 Tilt Angle For Advanced Code Reconstruction

The most important parameter in Advanced Code Reconstruction is the
value of the maximum tilt angle (α maximum) under which the code
reconstruction process is still possible.

- Reading features

We define the T ilt angle as the angle (α) between the laser beam and a line
parallel to the barcode label, as shown in Figure 4.3.

Figure 4.3 - Tilt angle

The formulas to calculate α maximum depend on various parameters such
as: label height, number of scans per second, code motion speed, etc. To
obtain α maximum for your application, please contact your Datalogic
representative.

You must remember that the decoder will be able to read the label with a tilt
angle between + α max and - α max as shown in Figure 4.4 (the shaded
zones are the NO READ zones).

4.2 PERFORMANCE

The scan rate is 1000 scans/sec.
Refer to the diagrams in par. 4.3 for further details on the reading features.

These diagrams are taken on various resolution sam ple codes at a 25 °C
ambient temperature depending on the conditions listed under each diagram.

If standard models do not satis fy specific requirem ents, contac t your nearest
Datalogic distributor, supplying code samples, to obtain complete inf orm ation
on the reading possibilities.

5 MAINTENANCE

5.1 CLEANING

Clean the laser beam output window (Figure A and Figure B, 1) periodically
for correct operation of the reader.

Dust, dirt, etc. on the window may alter the reading performance.
Repeat the operation frequently in particularly dirty environments.
Use soft material and alcohol to c lean the window and avoid any abrasive

substances.

WARNING

Clean the window of the DS8100
when the scanner is turned off or at
least when the laser beam is not
active.
