QX-830 Compact Industrial Scanner User’s Manual 5-81
Scanner Parameters
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 scanner will accept any Codabar symbol provided it doesn’t exceed
the system’s maximum capabilities.
When enabled, the scanner will reject any Codabar symbol that doesn’t match the fixed
length.
Fixed Symbol Length
This is the value against which all Codabar symbol lengths will be compared.
Check Character Type
When disabled, the scanner will not perform any character checking calculations on
decoded Codabar symbols.
When set to Mod 16, the scanner 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 scanner 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 scanner 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.
