2 Safety Precautions
2.1 Laser Safety
The following information is provided to comply with the rules imposed by
international authorities and refers to the correct use of the VB14 scanner.
Standard Regulations
This scanner utilizes a low-power laser diode. Although staring directly at the laser
beam momentarily causes no known biological damage, avoid staring at the beam as
one would with any very strong light source, such as the sun. Avoid that the laser
beam hits the eye of an observer, even through reflective surfaces such as mirrors,
etc.
This product conforms to the applicable requirements of both IEC 825-1 and CDRH
21 CFR 1040 at the date of manufacture. The scanner is classified as a Class 2 laser
product according to IEC 825-1 regulations and as a Class II laser product according
to CDRH regulations.
There is a safety device which allows the laser to be switched on only if the motor is
rotating above the threshold for its correct scanning speed.
The laser beam can be switched off through a software command (see also "Beam
Shutter" in the VisoSetup Help On Line).
The laser light is visible to the human eye and is emitted from the window on the front
of the scanner (figure 1.1 (7)).
Use of controls or adjustments or performance of procedures other than
those specified herein may result in exposure to hazardous visible laser
light.

2.1.1 General notes
Warning labels indicating exposure to laser light and the device classification are
applied onto the body of the scanner (figure 1.1).
Warning and device class labels
Disconnect the power supply
when opening the device during maintenance or installation to avoid exposure to
hazardous laser light.
The laser diode used in this device is classified as a class 3B laser product according
to IEC 825-1 regulations and as a Class IIIb laser product according to CDRH
regulations. As it is not possible to apply a classification label on the laser diode used
in this device, the following label is reproduced on the right.
Any violation of the optic parts in particular can cause radiation up to the maximum
level of the laser diode (7 mW at 630 to 680 nm).

3 General Features
3.1 INTRODUCTION
The VB14 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.
Standard Application Program A standard application program is factory-
loaded onto the VB14. This program controls
barcode reading, serial port interfacing, data
formatting and many other operating and con-
trol parameters.
It is completely configurable from a host com-
puter through the VisoSetup utility program
provided on CD-ROM with the scanner, or
through ESC sequences via the serial inter-
face.
Custom Application Programs If the Standard Application Program doesn't
meet your requirements, please contact your
local P+F distributor.

3.2 Description
Some of the main features of VB14 are listed below:
• small dimensions.
• Software programmable scanning speed.
• Linear and raster versions.
• modulated light versions for immunity to ambient light.
• 2 serial communication interfaces.
• supply voltage from 10 to 30 Vdc.
• reads all popular codes (1 dimensional).
• test mode to verify the reading features and exact positioning of the scanner with-
out the 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 VB14 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.
The four LEDs on the side of the scanner indicate the following:
The screw holes on the body of the reader are for mechanical fixture
(see section 1.1 (5)).
PWR/TXD LED (red) (figure 1.1 (1)) indicates the reader is connected to
the power supply or, when blinking (green), data transmis-
sion.
GOOD READ LED (red) (figure 1.1 (3)) is used to signal the possibility of a
successful barcode reading.
EXT TRIG LED (yellow) (figure 1.1 (2)) indicates external trigger activity.
Refer to see section 9.1.

8 Main Serial Interface
The signals relative to the following serial interface types are available on the input/
output connector of VB14 depending on the VB14 model (see Section 3.3).
If the interface type is not compatible with the current communication handshaking,
then the system forces the handshake to none.
The parameters relative to the interface selected (baud rate, data bits, etc.) can be
defined using the VisoSetup utility program or "Host Mode" programming procedure
through ESC sequences installed from the CD-Rom.
Details regarding the connections and use of the interfaces are given in the next
paragraphs.
RS232 Interface
The serial interface is used in this case for point to point connections; it handles
communication with the host computer and allows both transmission of code data and
the programming of the scanner. This is the default setting.
The following pins are used for RS232 interface connection:

Figure 8.2 RS232 control signals
If the RTS/CTS handshaking protocol is enabled, the VB14 activates the RTS232
output to indicate a message is to be transmitted. The receiving unit activates the
CTS232 input to enable the transmission.
RS485 full-duplex interface
The RS485 full-duplex interface is used for non-polled communication protocols in
point to point connections over longer distances than those acceptable for RS232
communications or in electrically noisy environments.

Figure 8.3 RS485 full-duplex connections
RS485 Half-Duplex Interface
The RS485 half-duplex (3 wires + shield) interface is used for polled communication
protocols.
It can be used in a master/slave layout, (see Section 12.4) exploiting a proprietary
protocol based on polled mode called MUX32 protocol, where a master device polls
slave devices to collect data.
The connector pinout follows:
Figure 8.4 RS485 half-duplex connections
This interface is forced by software when the protocol selected is MUX32 protocol.
In a Master/Slave Layout, the Multidrop address must also be set via serial channel
by the VisoSetup utility or by ESC sequences.

9 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
VisoSetup utility program or "Host Mode Programming", installed from the CD-Rom.
The following pins of the 25-pin connector are used to connect the RS232 auxiliary
interface:
Figure 9.1 RS232 auxiliary interface connections using hardware handshaking
The RTSAUX and CTSAUX signals control data transmission and synchronize the
connected devices. If the RTS/CTS handshaking protocol is enabled, the VB14
activates the RTSAUX output to indicate a message is to be transmitted. The
receiving unit activates the CTSAUX input to enable the transmission.

9.1 Inputs
The inputs available on the connector supplied with the scanner are the pins relative
to the External Trigger, as indicated below:
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 VisoSetup Help On Line.
The yellow LED (figure 1.1 (2)) is on when the External Trigger forces a current flow
through the EXT TRIG+ and EXT TRIG- pins.
This input is optocoupled and can be driven by both an NPN or PNP type command.
The connections are indicated in the following diagrams:
Figure 9.2 Input NPN command using external power
Figure 9.3 Input NPN command using VB14 power
