decoder
Specially developed decoder for reading bar codes with bad or soiled print images.
SOPAS-ET
PC configuration software, to run on Windows 2000

and Vista
TM
. Used for online com-
munication with the bar code scanner in the dialog (configuration, displaying reading
events, diagnosis) as well as for preparatory offline configuration of stand-alone devices or
the grouping of the same/different SOPAS-ET-compatible SICK devices in a project. The pa-
rameters are exchanged device-specific with the bar code scanner/the devices via upload
and download.
SOPAS-ET help
Online help which supports use of the SOPAS-ET configuration software. The parameter
functions of the bar code scanner are explained in the online help. Runs using an HTML
browser, such as "Internet Explorer

", and can be called up in the SOPAS-ET configuration
software.

Start/Stop operation
In this reading operation mode, only one object per reading pulse is located in the reading
area. Two external sensors or command strings control the beginning and end of the read-
ing pulse for the bar code scanner (stand-alone device). The length of the reading area is
determined in this case by the distance of both reading pulse sensors for the start (begin-
ning of the reading area) and stop (end of the reading area). The minimum reading distance
between two objects must always be greater than the length of the reading area.
In the case of combined use with other bar code scanners in a master/slave combination
(e.g. unidirectional double-side reading), the bar code scanner as a slave receives its pulse
signals from another bar code scanner (master). The bar code scanners are networked via
the CAN interface, the output of the master’s reading result via its RS- 232/RS-422/485
interface and/or the Ethernet interface.
Switching sequence
Sequence of the focus positions to be adjusted one after the other with the corresponding
depths of field. For this purpose, the numbering of the active distance configurations is en-
tered in the cross-reference list in the desired position.
