1 RAPID 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, 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.

STEP 3 – MODE BUTTON CONFIGURATION
The Mode Button 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)
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:
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.
* 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.

VB14N

Auto Learn
If you are configuring your scanner using the Mode Button, you must start with the Auto Learn
procedure.
1. Enter the Auto Learn function by holding the Mode push button pressed until the LEARN LED is
on.
2. Release the button to enter the Auto Learn function.
Once entered, the reader starts a procedure to automatically detect and recognize barcodes (by
type and length), which are presented to it (*). The laser turns on and the LEARN LED blinks to
indicate the ongoing process.
Figure 6 – Auto Learn Function
The procedure is as follows:
A) place the desired barcode on the
scanline.
B) wait until the LEARN LED stays
steady on (indicating the reader
has detected the 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 (refer to the
“Software Configuration Parameter
Guide” Help file).
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 following parameters are forced: Code Combination =
Single Label, Reading Mode = Linear. If necessary, these parameters can be
changed through Genius™.
* In case of Programming Barcodes (refer to the “ID-NET™: Programming Barcodes And Setup Procedure”
document).

VB14N
7
Auto Setup (Optional)
At the end of the Auto Learn procedure, you have the possibility to follow the Auto Setup procedure to
set up the reading parameters.
1. Enter the Auto Setup function by holding the Mode push button pressed until the SETUP LED is
on.
2. Release the button to enter the Auto Setup function.
3. 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.
Figure 7 – Auto Setup Function
The procedure is as follows:
A) place the desired barcode on the
scanline.
B) enter the AutoSetup function (the
laser turns on and the SETUP LED
blinks to indicate the ongoing
process)
C) 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.
NOTE
If your application has been configured using Mode Button, go to STEP 5.
Reset Scanner to Factory Default (Optional)
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, and all
LEDs blink simultaneously 3 times.

STEP 4 – INSTALLING GENIUS™ CONFIGURATION PROGRAM
Genius™is a Barcode 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.
Install the Genius™Software! (Download from www.pepperl-fuchs.com)
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.
