1 INTRODUCTION

1.1 PRODUCT DESCRIPTION

The DS6400 is a high performance laser scanner in a complete range of industrial bar code
readers offering an innovative and modular solution in terms of reading performance,
connectivity and maintenance, in addition to a completely new hardware and software
platform.

The DS6400 has been specifically designed for simple installation, easy use and flexibility.
An innovative mechanical design together with the Datalogic patent pending Step-a-Head
feature make it possible to rotate the reader head and the decoder base independently from
each other. Step-a-Head

TM

enables the DS6400 to always be installed in the ideal position,
by modifying the orientation of the connector panel while leaving the laser window in the
desired position. The need for space is minimized and installation is easier.

The DS6400 has an innovative linear motor designed to control the focus position of the
scanner via software. This dynamic system, called FLASH

TM,

is able to move the focus
position rail to rail, from the minimum position to the maximum position, in less than 10 msec.
In typical applications, where a DOF <1 meter is required, the focus position is adjusted in 4
msec.

The DS6400 can read all most popular bar codes even in the most difficult conditions, thanks
to a new generation decoder with Intel Xscale CPU and code reconstruction technology
(ACR™ 4).

This reader is also offered in a model with an integrated SW programmable oscillating mirror.

Great attention has been given to built-in connectivity for all market standards. Lonworks,
Profibus, DeviceNet and Ethernet bus have been integrated in dedicated versions of the
decoder base.

Some of the main features of DS6400 are listed below:

• scanning speed up to 1200 scans/sec;

• 2 serial communication interfaces

• reading all popular codes;

• supply voltage from 15 to 30 Vdc;

• electrical connection through connectors;

• high speed Lonworks connectivity for Master/Slave layout;

• built-in connectivity for Profibus, DeviceNet and Ethernet;

• programmable in 5 different operating modes to suit the most various barcode reading

system requirements;

• light source: solid state laser diode; the light emitted has a wavelength between

630~680nm.

• IP64 protection class of the enclosure (not yet available for Ethernet models).

Manufacturing is the traditional industry for Auto-ID applications, with a market becoming
mature, standardized reading solutions and a tough competition. Manufacturing has been the
target industry since the very beginning of the new 6000 family with the DS6300. The
DS6400 makes possible to enlarge the market applications including Transportation &
Logistics industry, making wider the Business Opportunities scenario.

1.3 OSCILLATING MIRROR MODELS

Oscillating mirror models are used when coverage of a large reading area is required, mainly
in picket fence applications.
The DS6400 scanner mounts a dedicated optic head with integrated oscillating mirror driven
by a linear motor. The speed, the precision, the repeatability, and the reliability of this driving
technology assure high level performance.

The new oscillating mirror is completely software controlled and software programmable. The
Genius™ software tool allows adjusting the linear motor speed (oscillating frequency) and
the upper and lower limits of the oscillation by defining the top and bottom line limit angles.

When the oscillating mirror is programmed to read barcode labels at very small angles,
position the reader to assure at least 10° for the Skew angle (see par. 2.4). This angle refers
to the most inclined or external laser line, so that all other laser lines assure more than 10°
Skew. This avoids the direct reflection of the laser light emitted by the reader.

INSTALLATION

2 INSTALLATION

To install the system follow the given procedure:

• Select the mounting location for DS6400;

• Mount the DS6400 scanner;

• Position the scanner with respect of the barcode;

• Proceed with system electrical connection;

• Install the Genius™ program on the PC and configure the scanner;

• Set the Flash™ dynamic focus by means of the Genius™ software tool.

When installing several scanners, take care to position them correctly so

that no laser beam enters the reading window perpendicularly and at the

same level of the output beam of the other scanners. This condition could

occur more frequently for side mounted applications. If these precautions

are not followed, it may occur that the laser of the blinded scanner starts

WARNING

blinking due to an internal circuit which temporarily turns the laser off

when detecting a power anomaly. To resolve this problem, it is sufficient

to slightly change the inclination and position of one of the two scanners

involved.

2.2 MECHANICAL MOUNTING

2.2.1 Mounting the Scanner

The DS6400 reader can be positioned and installed in the best way possible as a result of
the Step-a-Head™ feature. Thanks to the separation between Head and Base, you can
modify the orientation of the decoder base, and therefore display-keypad and connector
panels, while keeping the optic head in the correct reading position. The reading head and
the decoder base can be rotated independently from each other allowing the installation even
in the most critical locations.

Head Screws

Fixing Screw (4)

Figure 7 - Step-A-Head™ Feature

To rotate the head follow the given procedure:

. detach the head from the base by unscrewing the four fixing screws;

1

. rotate the head in the desired position;

2

loosen but don't remove the two screws on top of the head;

3.

4. affix the head onto the base carefully aligning the four fixing screws and progressively
tightening them about half-way;

5. completely tighten the two screws on top of the head;

6. completely tighten the four fixing screws.

Main Interface

The main serial interface is compatible with the following electrical standards:

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

The 20 mA Current Loop interface is available by using the C-BOX 100 with the optional
INT-30 accessory installed in it. The scanner communicates to the C-BOX 100 through the
RS232 interface and the INT-30 converts the signals.

The main serial interface type and its relative parameters (baud rate, data bits, etc.) are
selected via software using the Genius™ utility program. For more details refer to the
section "Main Serial Port" in the Genius™ Help On Line.

Details regarding the connections and use of the main interface selection are given in the
next paragraphs.

RS232 Interface

The main serial interface is used for communication with the Host computer and allows both
transmission of code data and configuring the reader. The overall maximum cable length
should not exceed 15 m (50 ft).

The following pins of the 25-pin and 26-pin connector are used for RS232 interface
connection depending on the reader model:

Pin Name Function

2 TX Transmit

3 RX Receive
4 RTS Request to send
5 CTS Clear to send
7 GND_ISO Main signal ground

The RTS and CTS signals control data transmission and synchronize the connected devices.

If the RTS/CTS hardware protocol is enabled, the DS6400 activates the RTS output to
indicate a message can be transmitted. The receiving unit must activate the CTS input to
enable the transmission.

DS6400

Inputs

The inputs of the reader are on the 25-pin and 26-pin connector (Figure D, 1 and Figure E, 1)
of the DS6400.

These inputs are called EXT_TRIG/PS, IN2/ENC, IN3 and IN4.

Pin Name Function

18 EXT_TRIG/PS A External trigger (polarity insensitive) for PS
19 EXT_TRIG/PS B External trigger (polarity insensitive) for PS

6 IN2/ENC A Input signal 2 (polarity insensitive) for Encoder
10 IN2/ENC B Input signal 2 (polarity insensitive) for Encoder
14 IN3A Input signal 3 (polarity insensitive)
15 IN4A Input signal 4 (polarity insensitive)
24 IN_REF Common reference of IN3 and IN4 (polarity insensitive)

IN2/ENC is normally used for the Encoder input. In PackTrack™ mode, it detects the
conveyor speed. The maximum Encoder frequency is 2 KHz.

EXT_TRIG/PS is the main presence sensor. When active, this input tells the scanner to scan
for a code and that decoding can take place. The yellow LED (Figure C,3) indicates the
EXT_TRIG/PS is active.

IN3 and IN4 can be used as the stop signal for the reading phase.

All inputs are optocoupled, polarity insensitive, and driven by a constant current generator;
the command signal is filtered through an anti-disturbance circuit which generates a delay
which can be set to 5 ms or 500 µs. In particular, EXT_TRIG/PS, IN3 and IN4 share the
same value which usually corresponds to 5 ms when using a photoelectric sensor, while
IN2/ENC has a different value which is set to 500 µs when this input is used for the Encoder.

Figure 28 - IN3/IN4 NPN Input Command using Scanner Power

Input devices can be supplied by either scanner power (VS and GND) or external power
supplies (Vext).

Electrical isolation between the input command logic and the scanner is maintained when
powering the input devices from an external supply voltage (Vext).

The driving logic of the input signals may be powered, for convenience, with the voltage
supply between pins 9 (VS) and 23 (GND) of the 26-pin I/O connector. In this case, however,
the device is no longer electrically isolated.

The voltage available on the 26-pin I/O connector, is physically the same as used to power
the scanner.

The electrical features of these inputs are:

Maximum voltage 30 V
Maximum current 10 mA

Outputs

Three general purpose outputs are available.

Pin Name Function

8 OUT 1+ Configurable digital output 1 – positive pin
22 OUT 1- Configurable digital output 1 – negative pin
11 OUT 2+ Configurable digital output 2 – positive pin
12 OUT 2- Configurable digital output 2 – negative pin
16 OUT 3A Configurable digital output 3 – polarity insensitive
17 OUT 3B Configurable digital output 3 – polarity insensitive

The function of the three outputs OUT1, OUT2 and OUT3 can be defined by the user.
Refer to Genius™ Help On-Line for further details.

INSTALLATION

By default, OUT1 is associated with COMPLETE READ event, which activates when the code
has been read correctly. In case the reader has been programmed to read several codes
within the same reading phase, the event activates when all codes have been read.

OUT2 is associated with NO READ event, which activates when no code has been read.

OUT3 is associated with NONE, which means that the output is always in Line State.

The OUT1 and OUT2 electrical features are given below:

Collector-emitter voltage 30 V Max.
Collector current (pulse) 130 mA Max.
Collector current (continuous) 40 mA Max.
Saturation voltage (VCE) 1 V at 10 mA Max.
Maximum power dissipation 90 mW at 50°C (Ambient temperature).

The limit requested by the maximum power dissipation is more important than that of the
maximum collector current: if one of these outputs is continuously driven, the maximum
current must not be more than 40 mA although 130 mA may be reached in pulse conditions.

When the load is powered by an external power supply, the voltage must be less than 30 V.

OUT3 has different electrical features, since it is a bi-directional solid state relay with built-in
current limit protection. If this output is continuously driven, the maximum current must be not
more than 200 mA although more than 300 mA may be reached in pulse conditions for an
ambient temperature of 25°C. At the maximum ambient temperature of 50°C the maximum
respective current is 150 mA continuous and 240 mA pulse.

The OUT3 electrical features are given below:

Maximum voltage ± 100 V
Collector current (pulse) 240 mA Max.
Collector current (continuous) 150 mA Max.

2.3.2 Lonworks Connectors

Do not connect an RS23
damage your Laptop PC.

CAUTION

The local network used by DS6400 exploits a Lonworks standard communication system
requiring only two wires (polarity insensitive) to enable a connection. The connector also

rovides a positive and a negative supplying wire. In this way, all the slave readers can be

p
powered by the master through the Datalogic standard cables.

When working in applications requiring enhanced synchronization capabilities, the DS6400
master reader (output) transmits two system signals named Sys_I/O and Sys_Enc_I/O to
slave readers (input). For example, when working with applications requiring an encoder the
signal is received by the master and directly transmitted to the slaves throug

he internal circuits generating the system signals are externally supplied by means of the

T
VS_I/O and REF_I/O pins and are isolated from the reader supply voltage.

The use of these system circuits is not required in all the operating modes (see pa

Network Termination

When building a Lonworks system the network must be properly terminated by positioning
BTK-6000 terminator in the DS6400 master reader and in the last DS6400 slave reader.

Each side of the terminator provides a different connector; thus, it can be inserted either into
the Lonworks 9-pin male connector of the master reader or in the Lonworks 9-pin female
connector of the last slave reader:

Lonworks Interface

The Lonworks network is used for both input and output connection to build a multi-sided or
omni-station system connecting several readers.

The DS6400 master usually employs the 9-pin female connector for output connection to the
first slave, while the 9-pin male one is terminated by inserting the BTK6000 terminator (see
par. 2.7.2 for details). If creating a T network configuration, it is necessary to use both
connectors to create the double branch line of slave readers.

Both connectors are always employed when connecting together the slave readers. In
particular, the 9-pin female connector is used for output connection and the male one for
input connection. The female connector is always terminated in the last slave reader to close
the system network.

The following diagram represents the connection between a DS6400-XXX-010 working as
master and a DS6400-XXX-010 working as a slave reader.

2.3.6 Power Supply

The supply voltage of a single scanner must be between 15 and 30 VDC.

Datalogic strongly recommends a minimum 24 VDC supply voltage when using a
master/slave configuration.

The power consumption of the different DS6400 models is slightly different.
In particular, when connecting several DS6400 readers in a master/slave connection, the
typical power consumption for each scanner is 15 W. There is a power peak of about
20 W lasting 5..10 seconds caused by the motor starting.

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.

Note that GND is internally connected to chassis. The cable shield is also connected to
pin 1 - CHASSIS.

2.5 POSITIONING THE SCANNER

The DS6400 reader is able to decode moving barcode labels at a variety of angles, however
significant angular distortion may degrade reading performance.

When mounting DS6400 take into consideration these three ideal label position angles:
Pitch 0°, Skew 10° to 30° and Tilt 0°.

Follow the suggestions for the best orientation:

The Pitch angle is represented by the value P in Figure 45. Position the reader in order to
minimize the Pitch angle.

P

Figure 45 - "Pitch" Angle

33

2

DS6400

The Skew angle is represented by the value S in Figure 46. Position the reader to assure at
least 10° for the Skew angle. This avoids the direct reflection of the laser light emitted by the
scanner.
For oscillating mirror models, this angle refers to the most inclined or external laser line, so that
all other laser lines assure more than 10° Skew.

2.6 TYPICAL INSTALLATIONS

2.6.1 Standard Installation

The DS6400 scanner is mounted on the ST-237 106° mounting bracket (see Figure 9) which
guarantees a built-in Skew angle (S in the figure below) of 16° with respect to the frame
plane (typically the Skew angle should be between 10° - 20°). This avoids the direct
reflection of the laser light emitted by the scanner. Furthermore, the bracket guides allow
adjusting the Tilt angle (T in the figure below, which is typically 0°) for the best scanner
orientation:

2.6.2 “45° Skew” Installation

The DS6400 scanner is mounted on the ST-210 90° mounting bracket (see Figure 11). By
adjusting the mounting bracket guides, reach 45° for the Skew angle (S in the figure below)
to avoid the direct reflection of the laser light emitted by the scanner:

2.7.2 Pass Through

When Pass Through is activated on the Auxiliary interface, the DS6400 reader (all models)
can be integrated in a network consisting of different scanners not provided with a Lonworks
interface.

This connection mode allows two or more devices to be connected to a single external serial
interface. The DS6400 transmits the messages received by its auxiliary interface (RS232
only) onto its main interface.

In this configuration a series of scanners 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 Pass Through connections each
scanner is provided with its relative External Trigger (multi P.S.).

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

For the RS232 connections the maximum cable length is 15 m (50 ft).

The DS4600A scanners represented in the following figures are configured in Pass Through
mode.

2.7.5 Local Lonworks Network

A local Lonworks network allows logically connecting a DS6400 master reader with up to 31
DS6400 slaves. Actually, the maximum number of readers to be employed in the network
depends on the system operating conditions; that is adopted operating mode and amount of
data stream.

When creating your network, always keep in mind the following guidelines:

• the Lonworks network logically supports a maximum number of 32 devices
(master + slaves);

• it is recommended to adhere to the 8-in-16 rule (not more than 8 devices in any 16 meter
bus segment;

• for DS6400 scanners the total bus length may extend up to 130 m (426 ft);

• the maximum number of DS6400 readers supported also depends on the type of power

propagation adopted by the system (see the specific power supply installation manual for
details).

Typically the layouts can be divided into Synchronized (single P.S.) or Multidata (multi P.S.)
networks. They can be small (up to 10 scanners) or large (more than 10 scanners).

Contact Datalogic Automation S.r.l. if your network requires a higher number of readers or in
case the application throughput is very high.

For further information on Lonworks network cabling and connections see the “LonWorks®
TPT Twisted Pair Transceiver Module User’s Guide”, available from the website:
www.echelon.com.

NOTE

For some DS6400 Lonworks Network layouts power is propagated through
the scanners. For these layouts a special setting is required
C-BOX 100 to pass scanner power to the presence sensor, encoder, etc.

Small Synchronized Network

When building a small local Lonworks network (less than 10 scanners), the DS6400 master
reader must be connected to a local host computer or a C-BOX 100 by means of a
CAB-60XX cable connected to the 25-pin or 26-pin D-sub male connector.

The master reader connects to the first slave reader of the system through the local
Lonworks 9-pin female connector. For Master/Slave models, the local Lonworks 9-pin male
connector must be properly terminated by inserting the BTK-6000 Lonworks terminator.
Fieldbus models are provided with an internal Lonworks terminator.

The slave readers are connected together through the local Lonworks connectors. Only the
9-pin female connector of the last slave reader must be terminated by the BTK-6000
terminator.

The presence sensor is connected and powered through the C-BOX 100 by the scanner and
is unique to the system. There is only a single reading phase and a single message from the
master reader to the Local Host. The On-Line operating mode is used for this layout.

Large Synchronized Network

When building a large local Lonworks network (more than 10 scanners), an SC6000
Controller must be used together with a PWO power supply/junction box unit. In this case the
SC6000 unit acts as the system master and is connected to the host through one of its
interfaces.

All scanners act as slaves and are connected to the SC6000 through the PWO power
supply/junction box. For DS6400 scanners, a single branch connector provides Lonworks
communications between the scanners and the SC6000 unit. Power is distributed evenly by
connecting groups of up to 4 Slave scanners through CAB-63XX cables. The last scanner on
the line requires a Termination connector.

Multidata Network

In this layout, one master and up to 7 DS6400 slave readers have their own P.S. and
therefore multiple reading phases. Each P.S. is connected through a C-BOX 100, which in
turn is connected to its relative scanner through a CAB-60XX cable.

The master sends all the individual messages collected from the Lonworks interface as well
as its own to the Local Host through its C-BOX 100.

The following image shows a system consisting of five readers, which are all connected
together using CAB-611X cables and each scanner is individually powered by PG6000
through C-BOX 100.

2.7.6 Fieldbus Network

The Fieldbus Ethernet model offers connectivity without any converter or adapter needed.

The DS6400 master Fieldbus communicates with a remote host (for ex. remote PC
connected via Internet) by means of a cable connected to the Fieldbus connector provided. It
can be activated by a signal generated by the remote Host or by a physical presence sensor.

The external signals (trigger, encoder) are connected to the master through the C-BOX 100.

The master reader connects to the first slave reader of the system through the local
Lonworks 9-pin female connector. Fieldbus models are provided with an internal Lonworks
terminator.

The slave readers are connected together through the local Lonworks connectors. Only the
9-pin female connector of the last slave reader must be terminated by the BTK-6000
terminator.

The example below shows a system powered by the PWR-240 where multiple slaves are
connected through CAB-63XX power cable. The master and all slaves are connected
together through the CAB-610X cables.

The same network layouts are available as for the DS6400 standard model.

2.8 FLASH™ DYNAMIC FOCUS

The DS6400 has an innovative linear motor designed to control the focus position of the
scanner via software. This dynamic system, called FLASH

TM,

is able to move the focus

position rail to rail, from the minimum position to the maximum position.

The FLASHTM functionalities are programmed via the GENIUS™ tool (refer to the GENIUS™
Help On-Line for details) and can operate in the following modes:

• Fixed Mode

• Continuous Mode

• Triggered Mode

• D-Flash™ Mode

2.8.1 Fixed Mode

In Fixed mode, the focus is set in the wished position via software (expressed in cm). This
mode represents the basic Flash™ function, in which the focus position is adjusted in
software and is stored in the scanner decoder. This function is similar to the focus
adjustment available for the DS6300 scanner with the great difference that the adjustment is
performed via software through the GENIUS™ tool and not through a manual adjustment of
an external screw.

Figure 62 – Flash™ Fixed Mode

2.8.2 Continuous Mode

In Continuous mode, the focus position is continuously moving from a minimum position to a
maximum position with a defined frequency (f1 in the figure below). This Flash™ function
allows exploiting the whole reading range of the current DS6400 when the object to be
detected is large and slow moving. Typical examples of applications for the Continuous
mode are front side reading of big pallets, or reading on a fork lift truck.

Figure 63 – Flash™ Continuous Mode

2.8.3 Triggered Mode

In Triggered mode, the focus position can be set depending on the received external input
(photocell, barrier, serial message…). This mode represents the most traditional Flash™
function, since it requires photocells, barriers or a dedicated interface to the Host (PC or
PLC). The excellent performance of the DS6400 optic platform allows covering an area of
80 x 80 cm containing a 38 mm/15 mils resolution code by using one photocell only.

Figure 64 – Flash™ Triggered Mode

2.8.4 D-FLASH™ Mode

In D-Flash™ mode, the focus position can be set depending on the measured distance (Dn
in the figure below) between the scanner and the scanned object. This is the most innovative
and flexible function, that makes different software implementations possible. The

On Line Operating Mode

Figure 69 - On Line Mode Selection

This operating mode requires the reader to be connected to an external Presence Sensor
using EXT TRIG/PS A and EXT TRIG/PS B inputs.

During the active phase of the presence sensor, the DS6400 reader tries to acquire and
correctly decode the code. In case the decoding phase is successful, the barcode characters
are transmitted on the serial interface. Otherwise, a no read message is sent.

Automatic Operating Mode

Figure 70 - Automatic Mode Selection

This operating mode does not require the connection to an external Presence Sensor.

When working in this mode the reader is continuously scanning, while the reading phase is
activated each time a barcode enters the reader reading zone. The reader stops reading
after an N number of scans without a code. Barcode characters are transmitted on the serial
interface. In case of a failed reading phase no message is sent to the host computer.

4 READING FEATURES

4.1 ADVANCED CODE RECONSTRUCTION (ACR™ 4)

The traditional way of barcode reading could be called “Linear Reading”. In this case, the
laser beam crosses the barcode symbol from its beginning to its end as shown in the
following figure:

Laser Beam

Figure 74 – 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. With just a set of partial scans on the label (obtained using
the motion of the label itself), the DS6400 is able to “reconstruct” the barcode. A typical set of
partial scans is shown in the figure below:

Code Direction

Figure 75 – 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.

4.2 PACKTRACK™

PackTrack™ is a patented operating mode for Datalogic Omni-Directional Reading Stations
used to read and correctly assign codes read on different packs when placed in the scanner
Reading Area at the same time.

In fact, in the following example, the codes of two or more consecutive packs are found at
the same time in the scanner reading area. Therefore, the condition occurs where, in the
sequence of the two packs, the code of the second pack is read first, just before the code of
the previous pack. A system without PackTrack™ would assign the code of the second pack
to first pack and vice versa, thus causing a gross error in sortation.

Figure 78 – PackTrack™ System Layout

Working in PackTrack™ mode requires the presence of an encoder and a presence sensor
to track the moving packs.

All PackTrack™ functionalities are programmed via the Genius™ tool (refer to the Genius™
Help On-Line for details).

66

READING FEATURES

4

For correct functioning, the PackTrack™ operating mode requires a calibration just after the
installation of the scanners. This operation is absolutely necessary to make the scanner
recognize its position in space. Thus, a fixed reference system is required.

PackTrack™ uses a right-handed reference system (right hand with thumb = X axis;
forefinger = Y axis; middle finger = Z axis) where the axis X coincides with the PS line, the Y
axis coincides with the conveyor direction and the Z axis is oriented upwards from the
conveyor (see figure below).

This coordinate system is absolute for the reading station, i.e. is valid for all the scanners
independently from their position or orientation with respect to the conveyor.

Three barcodes are placed along the scanline. For each of them, three coordinates are
shown.

4.4 READING DIAGRAMS

The reading diagram given below illustrates the convention used to calculate the minimum
and maximum reading distance for barcodes. This procedure allows calculating the reading
distance of your scanner when working with a focus different from the one displayed in the
reading diagrams given in par. 4.4.1 and par. 4.4.2.

Draw a straight vertical line at the minimum focus distance value; the points of intersection
between this line and the global reading area give the minimum reading distance.

Draw a circumference from the origin (0,0) with a radial distance equal to the maximum
scanner focus distance. The points of intersection between this circumference and the global
reading area give the maximum reading distance.
