Parameters
5.7.6.1.3
Outputting start/stop
parameter is activated, the start and stop characters are
output along with the code content.
The characters are therefore available for evaluating the reading results.
5.7.6.1.4
Check digit test
parameter is used to define the calculation method for the plausibility
check on the code contents. A check digit is calculated from the code contents and compa-
red with the check digit in the code. The selected method must match the method used du-
ring creation of the code. If the calculated check digit matches the check digit in the code,
the reading is regarded as a G
OOD
R
EAD
).
Check digits prevent misinterpretations and increase reading reliability.
5.7.6.2
Length
Codes with a defined number of rows and columns can be excluded from the reading pro-
cess via the parameters in the
group. Limiting the number of codes to be read redu-
ces the decoding time.
5.7.6.2.1
Code length
parameter to restrict the permitted number of characters in a
code.
• F
REE
: Codes of any code length are read.
• I
NTERVAL
: The
parameter can be used to define the minimum and maximum code
length. Only codes with a code length between these two values are read.
• F
IXED
: The
parameter is used to define several fixed code lengths. Only codes
with one of these defined code lengths are read.
