Large Intercharacter Gap (Code 39)
Fixed Symbol Length Status (Code 39)
Symbol Length (Code 39)
Important: When setting Symbol Length to any number other than 0, add 1 to
account for a check digit. For example, if your symbol has 3 characters, set Symbol
Length to 4.
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.
