7.General notes

– The beam hits the PCB at an angle of approx.15°

from the vertical if the scanner is installed

plane-parallel to the object surface. If the angle is less than 15°, the reflection is greater.

From around 5°, a total reflection occurs ==> And the barcode can no longer be read.

To minimize unwanted reflection

s, the barcode scanner should be fitted so that the scan-

ning beam hits at an angle of between 15° and 30°.

– The Sick programming software can be used to create an image of the barcode. This image

n be used to assess whether the set speed is correct. If the speed set in the CLV software

is too fast, then the barcode will appear stretched on the image. If the speed is too slow,

then the barcode will appear squashed.

– With the recorded image, the minimu

m/maximum code position should be set as accurately

as possible to hide any unwanted structures (e.g.PCB conveyor side wall) and thus reduce

the analysis time of the barcode scanner.

– With Data Matrix code, the continuous delimiting line determines the size and angular po-

sition of the barcode. The opposite "black-white" pattern identifies the cell size and the num-

ber of cells. This edge area must not be disturbed or damaged. There must also be a "rest

ne" one cell in size around the barcode. This zone must not contain any unwanted struc-

tures. (Otherwise the barcode position cannot be detected reliably).

There must only be one barcode in the template window (limit the template window) other-

wise you cannot be certain which barcode was found and decoded.

– Distribution board: Unwanted terminals (e.g. X2-

X4) must be bypassed by setting the

switch to ON.

2.12 Tips & tricks for the barcode scanner

2.12.1 Background

This technical information was written because there are a few changes in the CLV_Setup soft-

ware version 4.3 compared to older versions. 2

We have also integrated new knowledge and practical experience gained in using the PCB bar-

code scanner. 2

This is simply a supplement to 00193891-05 Retr

ofit in

structions for PCB barcode scanner and

will shortly be incorporated into these retrofit instructions. 2

2.12.2 Software installation

The CLV software must be installed on the default path (C:\Program Files\SICK\CLV) as it is only

this path that is enabled to run the programs in the firewall. 2

If a firewall message appears on the desktop or if no image is displayed in the ImageFTP window,

then you

should check whether the install path specified above was actually used. 2

If you still cannot establish a connection to the scanner,

then you should delete the address res-

olution protocol (ARP). 2

To do this, select "Start" and then enter the command "cmd" to swit

ch to the DOS level (see picture

below). You can then use the following commands: 2

2.12.3 ICR850 scanner

Please note that there are two different type ICR850 scanners: 2

ICR850-1920S03: Item number 00119679-01 Focus height 60 mm for SIPLACE HS / HF / X2

ICR850-1920S04: Item number 00119689-01

Focus height

85 mm for SIPLACE S / F 2

2.12.4 Network settings

The notebook (server) is assigned IP address 192.168.0.2 2

and subnet mask 255.255.255.0. 2

The scanner will have entered the IP

address

192.168.0.1 when it was supplied. 2

First the notebook is

assigned IP address

192.168.0.2.

For a detailed description, see:

00193891-05

Retrofit instructions for PCB bar-

code section 1.11.6.2

Setting the network address

Then establish the connection using a cross-over cable between the notebook and scanner 2

and start the CLV_Setup software. 2
