5 Introduction

5.1 Product description

The VB34 is the high-performance laser scanner in the VISOLUX family of barcode
readers for industrial applications. With its completely new hardware and software
platform, it offers innovative and modular solutions regarding performance,
communication and maintenance.

Easy installation and operation as well as high flexibility were the most important
features during the development of the VB34. Together with the Step-a-Head™
technology, for which a patent has been applied, the innovative mechanics makes it
possible to turn the read head and the decoder base assembly independently of each
other. Step-a-Head™ makes it possible to always install the VB34 in the ideal position
by changing the position of the base assembly while the read head with the laser
maintains its optimum position. This minimises the space requirements and simplifies
the installation.

Another innovation of the VB34 is the linear motor, which can be used to control the
reading position of the scanner via software. This dynamic system with the name
Flash™ is able to assume any reading position from the minimum position to the
maximum position in less than 10 ms. In typical applications with a reading distance
of less than 1 m, the reading position is reached in 4 ms.

Thanks to a new generation of decoders with StrongARM CPU and ACR technology
(ACR™ 3 reconstruction), the VB34 reads all current barcodes, even under
demanding ambient conditions.

The reader is also available in a version with an integrated, software-programmable
oscillating mirror.

Another focus in the system design was the communication capacity of the readers.
As interfaces, Lonworks, Profibus, DeviceNet and Ethernet were each integrated into
a separate version of the decoder base assembly.

Some of the significant features of the VB34 are:

Barcode reader VB34

Introduction

5.2 Available models

The VB34 scanner is available in various versions, which differ in the following
features:

• Optical system (head)

• Decoder (base assembly)
The following models are available:

VB34 - xxxx - OM - y

Max. distance Decoder model (base assembly)

__ = master/slave

Optical model (head) P = Profibus

_ = Standard B12 = Ethernet
OM = Oscillating mirror B7 = DeviceNet

5.3 Displays

The VB34 decoder base assembly has an LCD display for system messages and
menus of the configuration software. The three keys on the side of the display are
used for navigating in the menus of the configuration software (Figure 3.3).

The three status LEDs have the following functions:
Power ON (Red) indicates that the reader is switched on (Figure 3.3)
Phase ON (Yellow)indicates that the presence sensor is activated (Figure 3.3).
TX Data (Green)indicates that the primary serial interface transmits data

without errors (Figure 3.3).

5.4 Oscillating mirror models

Oscillating mirror models are used when large reading areas must be covered, mainly
in the case of horizontal barcodes (picket fence barcodes).

The VB34 contains a special optical head with an integrated oscillating mirror, which
is driven by a linear motor. Speed, precision, repeatability and reliability of this drive
technology guarantee a high performance.

The new oscillating mirror is completely software-controlled and programmable. The
configuration™ software makes it possible to adjust the speed of the linear motor (and
thus the oscillation frequency) as well as the upper and lower end position for the
oscillation process as an angle.

If the oscillating mirror is programmed to read barcodes at a very small angle, position
the reader in such a way that the visual angle is at least 10° (Chapter 6.4). This angle
mirrors the smallest deflection or the scanning line that is closest to the horizontal. All
other scanning lines have a visual angle of more than 10°. This prevents a direct
reflection of the laser beam emitted by the reader.

Introduction

Figure 5.1 Visual angle for oscillating mirror models

Otherwise, the scanner can be installed with a tilt angle of 17.5° in order to achieve a
horizontally symmetric deflection range.

Figure 5.2 Reading position of the oscillating mirror

In the above example, the zone in which the scanning lines meet the reflecting surface
vertically corresponds to a neutral area in the middle of the reading field.

The mirror can be deflected by up to 40°. In relation to the central axle of the exit
window, the deflection angle is asymmetric.

Introduction

By configuring the oscillating mirror speed to 19 Hz, a raster for recording and reading
quickly moving objects can be reproduced.

Hz Max. deflection

0 ... 5 40°

6 ... 10 30°
11 ... 15 20°
16 ... 19 10°

The number of scans on a given reading area can be increased by
limiting the raster width to the required minimum.

Note

The oscillating angles are selected in the software. The minimum and maximum
values are –2.5° and +37.5° respectively.

The scanner can be tilted so that the software setting of 17.5° lies on the horizontal
as a 0° reference.

Figure 5.4 End angle position for the oscillating mirror

These models have a higher read rate (1200 read processes/second) than the
standard models, which is not influenced by the oscillating mirror.

The following example shows a setting of +10° for the lower line and an angle of +20°
for the upper line (see figure below).

Inputs

The inputs of the reader are lead through on the 25-pin or 26-pin connector (Figure

6.11) of the VB34.
The inputs are labelled EXT_TRIG, IN2, IN3 and IN4.

Pin Description Function

14 IN3A Input signal 3 (polarity exchangeable)
15 IN4A Input signal 4 (polarity exchangeable)
24 IN_REF Common reference earth for IN3 and IN4 (polarity

exchangeable)

IN2 is normally used as encoder input. In the PackTrack™ operating mode, this input
is used to measure the speed of the band.

EXT_TRIG is the primary presence sensor. An active signal at this input informs the
reader that a code is to be read and decoded. A (yellow) LED indicates that the
EXT_TRIG signal is active.

IN3 and IN4 can be used as stop signal for the read cycle.
All inputs are galvanically isolated by means of optocouplers, independent of polarity

and are supplied via a constant current generator. The control signal is lead via a
debounce filter with a delay of 5 ms or 500 ms. EXT_TRIG, IN3 and IN4 work with the
same filter constant, which is usually set to 5 ms for photo cells, whereas IN2 is
operated with a filter constant of 500 ms if an encoder is connected.
