Parameters

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 Decoding 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 Increasing robustness 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 Errors in

L-pattern 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 GS1 format 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 Replacing the FNC1 character 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.
