As a result, the reading concentrates on the code elements and the decoding time is redu-
ced.
Codes with poor quality are generally ignored if the function is activated.
5.7.14.3.3
Decoding
The parameter
defines if the reading is optimized on time or on aggressive deco-
ding.
•
FAST
: Fast decoding is recommanded when the code quality is good and the decoding time
must be very short.
•
AGGRESSIVE
: Aggressive is usefull when decoding time is not that relevant, e.g. stationary
applications, but the code is of poor quality, e.g. low contrast, errors in the codes.
•
BALANCED
: Balanced meets the needs of applications in between.
5.7.14.4
Increasing robustness
The settings in the
group are used to increase the readability of co-
des with poor printing quality. However, these settings reduce the reading reliability.
5.7.14.4.1
Errors in L-pattern
According to the ISO/IEC 16022 standard, the code structure (L-pattern) must be marked
without gaps and must extend across the complete code height and width. If the
parameter is active, however, codes with an incorrect code structure are also
read.
During decoding, any gaps in the code structure are ignored. For the code to still be read,
there must be a quiet zone of at least 5 times the cell size around the code. This may increa-
se the decoding time.
5.7.14.5
GS1 format
The control characters in the GS1 data matrix code format can be replaced with alternative,
user-specific characters under the
group. Control characters in the GS1 data
matrix are used at the start of the code to identify the code format and within the code to
classify the data groups. The user-specific characters are entered as hexadecimal values
via the keyboard, clipboard, or the A
DD
VARIABLE
OR
CONSTANT
button.
5.7.14.5.1
Replacing the FNC1 character
In the GS1 code format, the
parameter can be used to define
user-specific characters for the FNC1 character (control character at the start of the code).
The characters are entered via the keyboard or clipboard.
