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

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 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.
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 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.

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.
