Step 3 – Focus the Scanner

The reading distance depends on the focus distance of the scanner and should be set
according to the application requirements. The Focus Position is set directly through the focus
adjustment screw on the front panel of the scanner. This screw moves the internal lens of the
scanner to change the focal length of the scanner. The setting is continuous but should not be
set beyond the limits "Too Far" or "Too Near" which appear on the display at the extremes of
the focus range. Although the scanner reads across the entire focus range, there are three
guaranteed positions which correspond to the reading diagrams in par. 7.4.

STEP 4 – MODE CONFIGURATION

Mode is the intuitive Human Machine Interface designed to improve ease of installation and
maintenance.

Status and diagnostic information are clearly presented by means of the five colored LEDs,
whereas the single push button gives immediate access to the following relevant functions:

• AutoSetup to self-optimize and auto-configure

reading performance in demanding applications

• AutoLearn to self-detect and auto-

reading unknown barcodes (by type and length)

• Focus Lock to memorize the mechanical focus

position

• Test Mode with bar graph visualization to check

The colors and meaning of the five LEDs are illustrated in the following table:

* In On-Line mode the TRIGGER LED corresponds to the active reading phase signaled by the Presence Sensor.
In Automatic and Continuous modes the TRIGGER LED is always on indicating that the reader is ready to read a
code.

** When connected to a Fieldbus network through the CBX500, the COM LED is always active, even in the
absence of data transmission, because of polling activity on the Fieldbus network.

During the reader startup (reset or restart phase), all the LEDs blink for one second.

On the back of the reader near the cable, the “POWER ON” LED indicates the laser scanner is
correctly powered.

When entering the Mode interface on the VB24-X1XX the Oscillating Mirror

2.1 PRODUCT DESCRIPTION

The VB24 laser scanner satisfies the most advanced needs of a wide range of users. It has
been developed focusing on the realistic requirements of its target market. The outstanding
result is an extremely compact, cost-effective and easy to use industrial scanner.

Program

This program controls barcode reading, serial port interfacing, data
formatting and many other operating and control parameters.

It is completely configurable from a host computer thr
Genius™ utility program

Some of the main features of VB24 are listed below:

• ACR4™ (Advanced Code Reconstruction – 4

• small dimensions and light weight

• software programmable scanning speed

• completely configurable via serial interface (Genius™)

• 3 serial communication interfaces (Main, Auxiliary, ID-NET™)

• supply voltage from 10 to 30 Vdc

• reads all popular codes

• test mode to verify the reading features and exact positioning of the scanner without the

th

need for external tools

• programmable in 4 different operating modes to suit the most various barcode reading

system requirements

• code verifier

• low power consumption

The VB24 uses a solid-state laser diode as a light source; the light emitted has a wavelength
between 630 and 680 nm. Refer to the section “Safety Precautions” at the beginning of this
manual for information on laser safety.

The protection class of the enclosure is IP65, the reader is therefore suitable for industrial
environments where high protection against harsh external conditions is required.

In Automatic and Continuous modes the TRIGGER LED is always on indicating that the reader is ready to read a
code.

** When connected to a Fieldbus network through the CBX500, the COM LED is always active, even in the
absence of data transmission, because of polling activity on the Fieldbus network.

During the reader startup (reset or restart phase), all the LEDs blink for one second.

On the back of the reader near the cable, the “POWER ON” LED indicates the laser scanner is
correctly powered.

2.2 ID-NET™

The ID-NET™ network is a built-in high-speed interface dedicated
for high-speed scanner interconnection. ID-NET™ is in addition to
the Main and Auxiliary serial interfaces.

The following network configurations are available:

 ID-NET™ M/S Synchronized: Single station – multiple scanners

 ID-NET™ M/S Multidata: Multiple stations – single scanner

ID-NET™ interface allows connection of scanners reading objects placed on independent
conveyors. All scanners are typically located far away from each other and they use a
dedicated presence sensor.

At the end of each reading phase, each scanner transmits its own data message to the host.

Thanks to ID-NET™, data collection among readers is accomplished at a high speed without
the need of an external multiplexing device. This leads to an overall cost reduction and to a
simple system wiring.

If necessary, the ID-NET™ baudrate can be set individually on each Slave

Baudrate parameter. Then follow the

2.2.1 How To Setup/Configure the Scanner Network

A complete ID-NET™ scanner network can be rapidly setup, as follows:

Mounting & Connection

1. Mechanically mount/install all the readers (refer to par. 3.2 and 3.3).

2. Wire ID-NET™ (refer to par. 4.3 or 5.3).

3. Connect a PC equipped with Genius™ to the planned Master scanner.

4. Power up the entire system.

Configuration

1. Launch Genius™.

2. From the Genius™ Device Menu select “Local Device Network Settings” and program the

Role of the Master scanner (Synchronized or Multidata).

This procedure requires the Network Baud Rate be the same for all Slaves and Master,
(500 kbs is the default value). It can be changed after network setup using Genius™
through the Master scanner. See also the alternative procedure in the note below.

3. At the prompt to "Send updated Network configuration to the Local Device" (Master)

choose "Yes".

4. Then run the NET-AUTOSET procedure from the Icon in the Devices Area. Genius™ sets

all slave scanners according to the Master Role (Synchronized or Multidata), and assigns
each a random address. If necessary, this address can be changed through the Network
Wizard.

5. Configure the System parameters via Genius™.

6. If using the CBX connection box equipped with a BM100 Backup module, perform System

Backup at the Master.

AutoLearn Function

Once entered, the reader starts a procedure to automatically detect and recognize barcodes
(by type and length), which are presented to it
to indicate the ongoing process.

The procedure is as follows:

- place the desired barcode on the scanline.

- wait until the LEARN LED stays steady on (indicating the reader has detected the
barcode).

- repeat, if needed, the above two steps to program up to 10 different barcodes (the LEARN
LED returns to the blinking state for the next code). If more than one barcode is detected in
the scan line, the Multi Label mode is enabled.

- exit the process by pressing the Mode push button once.

The scanner will restart at the end of the process, and then the detected barcodes are
automatically configured in scanner memory.

AutoSetup Function

Once entered, if a barcode label is positioned in front of the scanline, the scanner
automatically performs the optimal setup of the reading parameters for that specific barcode.

The procedure is as follows:

1

. The laser turns on and the LEARN LED blinks

- place the desired barcode on the scanline.

- enter the AutoSetup function (the laser turns on and the SETUP LED blinks to indicate the

ongoing process).

- wait until the SETUP LED stays steady on (indicating the reader has detected the

barcode).

This procedure ends either when the barcode is successfully decoded or after a timeout of
about 7 (seven) seconds.

The scanner will restart at the end of the process, and then the optimized reading parameters
for that barcode are automatically configured in scanner memory.

Focus Lock/Unlock

Once entered, the scanner automatically performs the Focus Lock procedure to save the
mechanical focus position to memory. If the mechanical focus position is changed by more
than the allowed tolerance of the value in memory, a diagnostic alarm will be sent to the
display.

The procedure is as follows:

- enter the Focus Lock function.

- wait until the "Focus locked at..." message appears on the display (indicating the focus

position has been saved to memory). The following parameters are set:

• Locked Position = your mechanical setting

• Focus Displacement (Alarm) = set (default to display only)

If the Focus lock has already been set, this procedure can be used to Unlock the focus value.
In this case control of the focus position is disabled.

The scanner will restart at the end of the process.

Reset Scanner to Factory Default

If it ever becomes necessary to reset the scanner to the factory default values, you can
perform this procedure by holding the Mode push button pressed while powering up the
scanner. At the end of the procedure (about 5-6 seconds), the Configuration and
Environmental parameters are reset, all LEDs blink simultaneously 3 times and the message
"Default Set" is shown on the display.

2.4 DISPLAY

The VB24 is equipped with a 2 line by 16 character LCD display which shows various
diagnostic, menu and operating mode messages according to a defined priority (0 = top
priority):

* Diagnostic Alarm Messages can be enabled/disabled in Genius™.

3.3 POSITIONING

The VB24 scanner is able to decode moving barcode labels at a variety of angles, however
significant angular distortion may degrade reading performance.

When mounting the VB24 take into consideration these three ideal label position angles: Skew
15° to 30°, Tilt 0° and Pitch 0°.

Follow the suggestions for the best orientation:

The Skew angle is represented by the value S in Figure 17. Position the reader to assure at
least 15° for the Skew angle. This avoids the direct reflection of the laser light emitted by the
VB24.

Figure 17 – VB24 Skew Angle

The Tilt angle is represented by the value T in Figure 18. Position the reader in order to
minimize the Tilt angle.

Figure 18 – VB24 Tilt Angle

By using the ACR4™ (Advanced Code Reconstruction) 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. 7.1 or the Help On Line for details.

4.3.1 ID-NET™ Cables

The following instructions are referred to Figure 28, Figure 29 and Figure 30.

• The general cable type specifications are: CAT5 twisted pair + additional CAT5 twisted

pair, shielded cable AWG 24 (or AWG 22) stranded flexible.

We recommend using DeviceNet cables (drop or trunk type) to the following reference
standards:

AN50325 – IEC 62026

UL STYLE 2502 80°C 30V

• Cable Shield MUST be connected to earth ground ONLY at the Master.

• NEVER use ID-NET™ cable shield as common reference.

• The ID-NET™ max cable length depends on the baudrate used, (see the Baudrate Table

below).

• For Common Power Connections use only 2 wires (ID+ and ID-).

- DC Voltage Power cable (Vdc – GND) should be handled as a signal cable (i.e. do not

put it together with AC cable):

- Wire dimensioning must be checked in order to avoid voltage drops greater than 0.8

Volts.

- Cable should lie down as near as possible to the ID-NET™ cable (avoiding wide loops

between them).

• Scanner's chassis may be connected to earth.

• Network inside the same building.

* Application dependent, contact your Pepperl+Fuchs GmbH representative for details.

NOTE

The default ID-NET™ baudrate is 500 kbps. Lower ID­allow longer cable length
authorized Pepperl+Fuchs GmbH personnel only.

4.3.3 ID-NET™ Network Termination

The network must be properly terminated in the first and last scanner of the network. This is
done by setting the ID-NET™ Termination Resistance Switch in the CBX100/500 to ON.

4.4 AUXILIARY RS232 INTERFACE

The auxiliary serial interface is used exclusively for RS232 point-to-point connections.

The parameters relative to the aux interface (baud rate, data bits, etc.) as well as particular
communication modes such as LOCAL ECHO can be defined using the Genius™ utility
program or Genius™ based Host Mode Programming.

The 9-pin female Auxiliary Interface connector inside the CBX is the preferred connector for
device configuration or communication monitoring.

Figure 31 - 9-pin female connector

If permanent system wiring is required, the following pins are used to connect the RS232
auxiliary interface:

Do not connect the Aux Interface to the CBX spring clamp connectors and

NOTE

4.5 INPUTS

There are two optocoupled polarity insensitive inputs available on the scanner: Input 1
(External Trigger) and Input 2, a generic input:

The electrical features of both inputs are:

Maximum voltage: 30 Vdc

Maximum current: 12 mA (scanner) + 12 mA (CBX)

An anti-disturbance filter is implemented in software on both inputs so that the minimum pulse
duration is ≅ 5 milliseconds. This value can be increased through the software parameter
Debounce Filter.

The External Trigger input is used in the On-Line operating Mode and tells the scanner to scan
for a code. The active state of this input is selected in software. Refer to the Genius™ Help On
Line.

The yellow Trigger LED (Figure A

, 3) is on when the active state of the External Trigger

corresponds to ON.

This input is optocoupled and can be driven by both an NPN and PNP type command. The
connections are indicated in the following diagrams:

4.5.1 Code Verifier

If the VB24 is used as a Code Verifier, the verifier code can be configured in software through
the Genius™ configuration program. However it is also possible to use one of the inputs to
trigger when the scanner should store a code read as the verifier code.

The Code Verifier parameter must be enabled, and the configuration parameters to allow
correct Code Type reading must be saved to the scanner in order to read the verifier code.

When the selected input is activated, the next read code will be stored as the verifier code in
the scanner's non-volatile (Flash) memory.

4.6 OUTPUTS

Two general purpose outputs are available.

The meaning of the two outputs Output 1 and Output 2 can be defined by the user (No Read,
Right, Wrong, etc.). Refer to the Genius™ Help On Line.

By default, Output 1 is associated with the No Read event, which activates when the code
signaled by the external trigger is not decoded, and Output 2 is associated with the Complete
Read event, which activates when all the selected codes are correctly decoded.

The output signals are fully programmable being determined by the configured
Activation/Deactivation events, Deactivation Timeout or a combination of the two.

There are two optocoupled polarity insensitive inputs available on the scanner: Input 1
(External Trigger) and Input 2, a generic input:

The electrical features of both inputs are:

Maximum voltage: 30 Vdc

Maximum current: 12 mA

An anti-disturbance filter is implemented in software on both inputs so that the minimum pulse
duration is ≅ 5 milliseconds. This value can be increased through the software parameter
Debounce Filter.

The External Trigger input is used in the On-Line operating Mode and tells the scanner to scan
for a code. The active state of this input is selected in software. Refer to the Genius™ Help On
Line.

The yellow Trigger LED (Figure A

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 Genius™ Help On Line.

6.1 POINT-TO-POINT

In this layout the data is transmitted to the Host on the main serial interface. A Genius™ based
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.

CBX500

In this layout a single scanner functions as a Slave node on a Fieldbus network. The data is
transmitted to the Host through an accessory Fieldbus interface board installed inside the
CBX500 connection box.

Scanner configuration can be accomplished through the Auxiliary interface using the Genius™
configuration program or Genius™ based Host Mode programming.

In Local Echo communication mode, data is transmitted on the RS232 auxiliary interface
independently from the Fieldbus 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.

6.2 PASS-THROUGH

Pass-through mode allows two or more devices to be connected to a single external serial
interface.

Each VB24 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.

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

The Main and Auxiliary ports are connected as shown in the figure below:

An alternative Pass-Through layout allows the more efficient ID-NET™ network to be used.
This layout is really an ID-NET Master/Slave Multidata layout which also allows each scanner
(Master and Slaves) to accept input on the Auxiliary interface, for example to connect a device
such as a hand-held reader for manual code reading capability.

Each VB24 transmits its own messages plus any messages received by its Auxiliary interface
onto the ID-NET™ interface. The Master passes all messages 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.

6.3 ID-NET™

The ID-NET™ connection is used to collect data from several scanners to build a multi-point
or a multi-sided reading system; there can be one master and up to 31 slaves connected
together.

The slave scanners are connected together using the ID-NET™ interface. Every slave
scanner must have an ID-NET™ address in the range 1-31.

The master scanner is also connected to the Host on the RS232/RS485 main serial interface.

For a Master/Slave Synchronized layout the External Trigger signal is unique to the system;
there is a single reading phase and a single message from the master scanner to the Host
computer. It is not necessary to bring the External Trigger signal to all the scanners.

The main, auxiliary, and ID-NET™ interfaces are connected as shown in the figure below.

NOTE

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
VB24 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 RS232/RS485 main serial interface.

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.

7 READING FEATURES

7.1 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:

Figure 77 – 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 scanner is able to “reconstruct” the barcode. A typical set of
partial scans is shown in the figure below:

Figure 78 – 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.

ACR4 therefore has an intrinsic ability to increase the reading percentage of damaged codes
as in the examples below:

7.2 LINEAR CODE READING

The number of scans performed on the code by the VB24 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.

7.2.1 Step-Ladder Mode

If scanning is perpendicular to the code motion direction (Figure 82), 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

For example, the VB24 (800 scans/sec.) for a 25 mm high code moving at 1250 mm/s
performs:

Figure 82 - "Step-Ladder" Scanning Mode

[(25/1250) * 800] - 2 = 14 effective scans.

7.2.2 Picket-Fence Mode

If scanning is parallel to the code motion, (Figure 83), 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

Figure 83 - "Picket-Fence" Scanning Mode

For example, for a 60 mm wide code moving in a point where the reading field is 160 mm wide
at a 2000 mm/s speed, the VB24 (800 scans per sec.), performs:

[((160-60)/2000) * 800] - 2 = 38 effective scans
