Specify Decoding Area
If
Specific Area Decoding
is enabled, the engine only reads barcodes that intersect the predefined
decoding area.
The default decoding area is an area of 40% top, 60% bottom, 40% left and 60% right of the engine
’
s field
of view, as shown in the figure below. In the following example, the white box is the decoding area. Since
Barcode 1 passes through the decoding area, it will be read. Barcode 2 does not pass through the
decoding area, so it will not be read.
You can define the decoding area using the
Top of Decoding Area
,
Bottom of Decoding Area
,
Left of
Decoding Area
and
Right of Decoding Area
barcodes as well as numeric barcode(s) that represent(s)
a desired percentage (0-100). To learn how to program decoding area, see
Appendix 5
