D.5.20 Posi Code (Reduced Space Symbology)
Enable
Setting this parameter to on enables "Posi Code" scanning capability.
Enable Limited A and Enable Limited B
"Posi Code" is a "position" based symbology. A position based symbology de-couples the
widths of the bars from their positions. The centers of the bars are specified to be laid out on
a grid of equally spaced parallel lines. The distance between these grid lines is called the G-
dimension and is analogous to the X-dimension of conventional bar codes.
There are two variations of this code: Posi Code A, and Posi Code B.
Minimum and Maximum Length
The length of a code refers to the number of characters (i.e., human readable characters), in-
cluding check digit(s). Double-tapping on these parameters displays a screen in which you
can set the minimum and maximum allowable code lengths – 2 to 80.
D.5.21 Composite
