Barcode length
Use the L1 as minimum length option if you know the minimum length of the
codes in your application!!!
- To optimize decoding performance and increase security, select the same
length as the minimum length in your application (do not select a shorter
length!!).
= [barcode data] + [Check digit]
- Recommended minimum length = 4 characters.
- Interleaved 2 of 5 always encodes an even number of characters.
- For codes with an odd number of characters, you can add a last character
printed as 5 narrow bars (not transmitted).
- For GTIN compatibility set barcode length to one fixed length of 14 characters
- compose 1 or 2 or 3 fixed lengths provides the best performance
and security if the codes in your application have fixed lengths
- recommended minimum length = 4 characters
IMPORTANT: Do not select a fixed length of "2 characters" unless
absolutely necessary - Interleaved 2 of 5 is not a secure symbology
and your product will find "bar codes" even where they don't exist !!!
Length mode
- L1 = Codes with as many characters as specified by L1 and longer are read
(L2 and L3 are not used).
