Security Level 3:
If you selected Security Level 2 and misdecodes still occur,
select this security level. Be advised, selecting this option is an extreme
measure against mis-decoding severely out of spec barcodes. Selecting this
level of security significantly impairs the decoding ability of the decoder. If you
need this level of security, try to improve the quality of the barcodes.
Intercharacter Gap Size
The Code 39 and Codabar symbologies have an intercharacter gap that is typically
quite small. Due to various barcode-printing technologies, this gap can grow larger
than the maximum size allowed, preventing the decoder from decoding the symbol.
If this problem occurs, scan the
Large Intercharacter Gaps
parameter to tolerate
these out-of-specification barcodes.
Macro PDF Features
Macro PDF is a special feature for concatenating multiple PDF symbols into one file.
The decoder can decode symbols that are encoded with this feature, and can store
more than 64 Kb of decoded data stored in up to 50 MacroPDF symbols.
CAUTION:
When printing, keep each Macro PDF sequence separate, as each sequence has unique identifiers.
Do not mix barcodes from several Macro PDF sequences, even if they encode the same data. When scanning
Macro PDF sequences, scan the entire sequence without interruption. When scanning a mixed sequence, two
long low beeps (Low/Low) indicates an inconsistent file ID or inconsistent symbology error.
