Description
Polarity
Saved: If dark code is saved on light back-
•
ground, the reader can read dark code on light
background faster. The same is true for in-
verse polarity, that is, light codes on dark
background.
Dynamic: Any code polarity is read, regardless
•
of whether the saved code was dark on light
background or light on dark background.
Number of rows and columns:
Saved: The reader decodes the data matrix
•
faster only if a data matrix has the same num-
ber of rows and columns as the saved code.
Dynamic: The reader can decode a data ma-
•
trix if the number of rows and columns differs
from the saved code.
Height and width of the code in the image:
Saved: The reader decodes the data matrix
•
faster if a data matrix has a size similar to that
of the saved code.
Dynamic: The reader can decode the data
•
matrix if a data matrix is considerably larger or
smaller than the saved code.
Ratio of width to height of the code in the image.
This is used only if "Dynamic" is set for the size.
Saved: The reader decodes faster a data
•
matrix with the same "aspect ratio" as the
saved code.
Dynamic: The reader can decode a data ma-
•
trix with a different "aspect ratio" from the
saved code.
Turning the code in the image:
Saved: The reader decodes a data matrix with
•
a roll angle similar to the saved code faster.
Dynamic: The roll angle is not limited. The
•
reader can decode a data matrix regardless of
the turning.
