Large Intercharacter Gap (Code 39)
Usage: Large Intercharacter Gap is helpful for reading symbols that are
printed out of specification.
Caution: Do not use Large Intercharacter Gap with Narrow Margins
enabled since a large intercharacter gap (over 3x) could cause a narrow
margins (5x) to be interpreted as an intercharacter gap.
Definition: When enabled, the scanner can read symbols with gaps between symbol
characters that exceed three times (3x) the narrow element width.

Fixed Symbol Length Status (Code 39)
Definition: When enabled, the scanner will check the symbol length against the sym-
bol length field. If disabled, any length would be considered a valid sym-
bol.

Symbol Length (Code 39)
Usage: Fixed Symbol Length helps prevent truncations and increases data

Definition: Specifies the exact number of characters that the scanner will recognize
(this does not include start and stop and check digit characters). The
scanner ignores any symbol not having the specified length.
