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 VB14A scanner.
2.2 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 EN 60825-1 and CDRH
21 CFR 1040 at the date of manufacture. The scanner is classified as a Class 2 laser
product according to EN 60825-1 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 motor and laser beam can be switched off through a software command (see also
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 3.1 (7)).
General notes
Warning labels indicating exposure to laser light and the device classification are
applied onto the body of the scanner (figure 3.1).

6.2 Electrical Connections
The VB14A models are equipped with a cable terminated by a 25-pin male D-sub
connector for connection to the power supply and input/output signals.
The details of the connector pins are indicated in the following table:
Figure 6.6 25-pin male D-sub connector
Do not connect GND and SGND to different (external) ground
references. GND and SGND are internally connected through filtering
circuitry which can be permanently damaged if subjected to voltage
drops over 0.8 V DC.

6.2.1 Power supply
Power is supplied to the scanner through the pins provided on the 25- pin connector
used for communication with the host:
Figure 6.7 Power supply connections
The power must be between 10 and 30 V DC only.
It is recommended to connect pin 1 (CHASSIS) to a common earth ground.
6.2.2 Main Serial Interface
The signals relative to the following serial interface types are available on the input/
output connector of VB14A.
If the interface type is not compatible with the current communication handshaking,
then the system forces the handshake to none.
The main interface type and relative parameters (baud rate, data bits, etc.) can be set
using the VisoSetup utility program or "Host Mode Programming" procedure through
ESC sequences.
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:

If the RTS/CTS handshaking protocol is enabled, the VB14A 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 (5 wires + shield) 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.
The connector pinout follows:
Figure 6.10 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 6.24) 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:
