Interleaved 2 of 5
Interleaved 2 of 5 is a continuous, two width symbology capable of encoding
an even number of numerics. Odd length messages are usually padded with
a leading 0. Each pair of digits is represented by five bars and five spaces. The
bars encode the first digit: two of these five bars are wide, the other three are
narrow. Following each bar is a space; collectively, the spaces encode the
second digit of the pair. Interleaved 2 of 5 characters are spatially efficient for
the set of numerics.
Interleaved 2 of 5
The start/stop characters are short, but not secure. Their patterns can occur
erroneously in partial scans of a symbol. As a result Interleaved 2 of 5 is prone
to misreads when the scanning path does not include both quiet zones.
Default = On.

Decoding
The 3700 Wedge uses industry standard decoding algorithms to ensure data
integrity. Adaptive decoding employs a more aggressive decoding algorithm
that is more tolerant when bar code symbols do not conform to the symbology
specifications and that results in snappier" scanning. Default = Adaptive.

Adaptive
Programming Tip: If a symbology won't be used, we recommend turning it off
to minimize the chance of a misread.
