Set Length: This option allows you to specify the
length of the barcodes you want to read. This
could be useful if you know that all valid
barcodes will be a specific length or a range of
lengths.
There are four ways to specify the allowed
barcode lengths. Let A refer to the first length
field and B refer to the second length field.
1) One Discrete Length – Set A to the discrete
length and B to 0. Only barcodes with an exact
length of A are decoded.
2) Two Discrete Lengths – Set A greater than B
(both non-zero). Only barcodes with lengths A
or B are decoded.
3) Length Within Range – Set A less than B (both
non-zero). Barcodes between and including A
and B are decoded.
4) Any length – Set A to 0. Any barcode length
is decoded.
