Appendix
Reading gate, reading interval
Time window in which the ICR890 System switches on the illumination and attempts to
recognize valid codes from the read information. The reading gate can be shorter than the
external reading pulse, depending on the output mode of the selected reading result.
Reading pulse
Triggering of the internal
Ö
reading gate via an ICR890 System external pulse is carried out
by means of a photoelectric reflex switch or a command from the host via the serial
interface.
Reading result
Electronic representation of the data contents of the code which has been read together
with
Ö
reading diagnosis data in a
Ö
data output string after completion of the reading
pulse.
Result status output
Functions of both switching outputs “OUT 1“ and “OUT 2“ during reading operation.
Indicates each status of the reading result without displaying its contents (e.g. “good read“).
One status per output can be provided with the SOPAS-ET Configuration Software. The
“result“ LED is coupled with the “Result 2“ output.
Saving to the ICR890 System
The application-specific
Ö
parameter set can be stored on the ICR890 System either
temporarily of permanently. In the case of temporary storage, the parameter set is only
contained in the working memory (RAM) and is lost as soon as the power supply is switched
off. In the case of permanent storage, the parameter set is also transferred to the EEPROM
of the ICR890 System and saved as a current data set after switching off. The default
setting is deposited in a Read Only Memory (ROM) irrespective of this.
Sending point
Output time of the reading result in relation to the start of the
Ö
reading pulse and the
internal
Ö
reading gate.
SMART decoder
Specially developed
Ö
decoder for reading bar codes with extremely small code heights and
or bad or soiled print images.
SOPAS-ET
PC configuration software, to run on Windows 98
TM
, ME
TM
, NT 4.0
TM
, 2000
TM
and Windows
XP
TM
. Allows offline configuration (adaptation to local reading conditions) and online
operation of the ICR890 System in dialogue. The
Ö
parameter set to be processed using
the ICR890 System can be exchanged by means of
Ö
upload and
Ö
download.
SOPAS-ET Help
Online help which supports use of the SOPAS-ET Configuration Software. The parameter
functions of the ICR890 System and the respective value range are explained in the online
help. Runs using an HTML browser, such as “Internet Explorer
TM
“, and can be called up in
the SOPAS-ET Configuration Software.
