Symbologies
Large Intercharacter Gap
When disabled, the spaces between characters, or the "intercharacter gap", are ignored
during the decode process.
Note: If the intercharacter space is large enough to be considered a margin, the symbol
will not decode, regardless of this parameter's setting.
Fixed Symbol Length Status
When disabled, the imager will accept any Codabar symbol provided it doesn't exceed the
system's maximum capabilities.
When enabled, the imager will reject any Codabar symbol that doesn't match the fixed
length.
Symbol Length
This is the value against which all Codabar symbol lengths will be compared.
Check Character Type
When disabled, the imager will not perform any character checking calculations on
decoded Codabar symbols.
When set to Mod 16, the imager will perform a modulus 16 check character calculation on
the symbol. If the symbol does not pass this calculation, it will not be decoded.
When set to NW 7, the imager will perform an NW7 modulus 11 check character calculation
on the symbol. If the symbol does not pass this calculation, it will not be decoded.
When set to Both, the imager will perform both the Mod 16 and NW7 modulus 11 check
character calculations on the symbol. If the symbol does not pass either calculation, it will
not be decoded.
