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:

• Read rate of up to 1200 read processes/second

• 2 serial interfaces

• Reading all current codes

• Operating voltage of 15 to 30 V DC

• All electrical connections pluggable

• Fast Lonworks interface for master/slave configurations

• Supports Profibus, DeviceNet and Ethernet

• 5 operating modes for an optimum adjustment to different application requirements

• Light source: laser diode with a wave length of 630 to 680 nm

• IP64-protected housing (for Ethernet models not yet available)

Auto-ID applications are traditionally used in the area of production. With increasing

marketability, standard solutions and a dynamic competition develop. The VB3x

family with the model VB33 also has its roots in production applications. The VB34

opens up new areas of application such as, for example, transport and logistics

applications, in which the practical advantages of the new technologies come to the

fore.

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:

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.

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.

By configuring the oscillating mirror speed to 19 Hz, a raster for recording and reading

quickly moving objects can be reproduced.

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).

6.2 Mechanical installation

6.2.1 Installation of the reader

Thanks to Step-a-Head™, the VB34 reader can be adjusted and installed in the ideal

reading position. By separating the head and the base assembly, you can change the

adjustment of the decoder base assembly and thus of the display, key pad and

connectors, while the head with the optical reading system maintains its optimum

position. The head and the base assembly can be turned independently of each other,

thus making a successful installation possible even in critical environments .

Figure 6.2 Step-a-Head™ function

To turn the head of the reader, perform the following steps:

1. Remove the head from the base by the unscrewing the four fixing screws.

2. Turn the head into the desired position.

3. Unscrew the two screws on the head.

4. Fix the head on the base assembly by tightening the four fixing screws again.

5. Tighten the two screws on the head.

The following figures show the total dimensions of the standard model, the oscillating
