Data decoding security parameters
Description
Data decoding security parameters allow you to ensure that the
ScanPlus transmits the correct data after decoding, whatever the
reading conditions or quality of the bar codes read.
Predefined security levels
The Normal Security Level optimizes the reading speed for most
situations.
Only select Medium and High Security Levels when using poor-
quality bar codes or for critical applications.
The predefined security level parameters can be modified
individually.
Increasing the level of security reduces the reading speed.
Data security and barcode length
The reliability of the barcode data transmitted can depend on the
symbologies used—some symbologies are more "fragile" than others
and errors may occur due to incorrect interpretation of code lengths.
You can configure the ScanPlus to transmit data for codes of 1 or 2
fixed lengths only or codes with a known minimum length
(
If you use the Compose Minimum Length option, we recommend that you use a check digit
and the Consecutive same read data validation feature provided below to ensure that the
same read result is obtained on 2 or more successive reads before the read is validated.
