Space insertion:
This option inserts spaces in position 2, 7, 13,
of the data string for use in library systems.
ST/SP translation:
This option enables the translation and
transmission of the start and stop characters.
Thus if the option ST/SP: abcd/tn*e is chosen,
the start character is converted to lower case,
e.g. from A, B, C or D to a, b, c, or d
respectively and the stop character is
converted from A, B, C or D to t, n, *, or e
respectively. The next figure shows the
resulting format for these options with a
Codabar label using A and B as start and stop
characters and 1 2 3 4 5 6 as data characters.
For string format see figure 3.26.
Minimum data characters:
Codabar labels are checked for a minimum of
1, 3 or 5 characters are set by the user. If the
number of characters in the label is shorter
than the number set, the label will be rejected.
If the fixed length option is used for Codabar
type labels then such labels will additionally be
checked for fixed length.
Inter character gap check:
This option enables the reading of Codabar
labels with a large or irregular gap between
characters. Checking the gap means that it is
not allowed to have a gap. Disable the gap
check allows gaps in the bar code.
