1RAPID CONFIGURATION
NOTE
This chapter illustrates a Stand Alone application. For other types of
installations, such as ID-NET™, Fieldbus, Pass-Through, Multiplexer Layout,
etc., refer to chapters 4, 5 and 6. For complete scanner configuration using
the Genius™ configuration program, refer to the Context-Sensitive Help On-
Line.
STEP 1 – CONNECT THE SYSTEM
To connect the system in a Stand Alone configuration, you need the hardware indicated in
Figure 1.
In this layout the data is transmitted to the Host on the main serial interface.
In Local Echo communication mode, the RS232 auxiliary interface can be used to transmit
data 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.

STEP 2 – MOUNT AND POSITION THE SCANNER
VB24 Standard Models
1. To mount the VB24, use the mounting bracket to obtain the most suitable position for the
reader as shown in the figures below.
Figure 3 - Positioning with Mounting Bracket
2. When mounting the VB24 take into consideration these three ideal label position angles:
Skew 15° to 30°, Tilt 0° and Pitch 0°.
Assure at least 15° Minimize Minimize
Figure 4 –Skew, Tilt and Pitch Angles
3. Refer to the Reading Diagrams in par. 7.4 to decide the distance your scanner should be
positioned at.

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.
1. Power up the scanner.Wait for the power up sequence to finish. By default the scanner focus is in
the Unlocked positio
n. The alternating message on the display shows the mechanical Focus
Position.
2.
Using a screwdriver turn the focus adjustment screw in the desired direction, clockwise (focus nearer to
the scanner) or counterclockwise (focus farther from the scanner). The f
ocus position in centimeters and
inches is shown on the scanner display.
NOTE
The value of the Focus Position must be stored in memory. If the mechanical position changes by
more than the allowed tolerance of the value in memory, an alarm will be sent.
See the Focus
Lock function in step 4, Mode Configuration.
As an additional visual aid during focusing, the indicator LEDs show the relative focus position

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-
configure for
reading unknown barcodes (by type and length)
•Focus Lock to memorize the mechanical focus
position
•Test Mode with bar graph visualization to check
static reading performance
The colors and meaning of the five LEDs are illustrated in the following table:
LED
Color
Description
READY
Green
This LED indicates the device is ready to operate.
GOOD
Green
This LED confirms successful reading.
TRIGGER
Yellow
This LED indicates the status of the reading phase. *
COM
Yellow
This LED indicates active communication on main serial port. **
STATUS
Red
This LED indicates a NO READ result.
* 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.
NOTE
When entering the Mode interface on the VB24-X1XX the Oscillating Mirror
remains in the default fixed position (0°) in order to make barcode reading
easier while performing the Mode functions.

barcode).
C) 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.
3. 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.
NOTE
If the barcode cannot be read because of low contrast or excessive ambient
light, you can perform the AutoSetup function to optimize the optical
parameters. Then you can perform AutoLearn to recognize the barcode
symbology.
NOTE
On exit from Autolearn, the foll
owing parameters are forced: Code
Combination = Single Label, Reading Mode = Linear. If necessary, these
parameters can be changed through Genius™.

STEP 5 – INSTALL GENIUS™ CONFIGURATION PROGRAM
Genius™is a scanner configuration tool providing several important advantages:
•Wizard approach for new users;
•Multi-language version;
•Defined configuration directly stored in the reader;
•Communication protocol independent from the physical interface allowing to consider the
reader as a remote object to be configured and monitored.
This configuration procedure assumes scanner connection to a CBX100/500. Genius™,
running on a laptop computer, is connected to the scanner auxiliary port through the
CBX100/500 9-pin connector. To communicate with the scanner, Genius™ performs an auto
baudrate detection starting from its default parameters which are 115200, 8, N, 1. These
parameters can also be set in the Genius™ Tools>Options>Communications window.
Wizard for Quick Reader Setup
After installing the Genius™ software program the following window appears asking the user
to choose the desired configuration level.
Figure 8 - Genius™ Wizard Opening Window
The Wizard option is advised for rapid configuration or for new users, since it shows a step-by-
step scanner configuration.
