3.3.6. Options for 2of5 and S-Code
Code 2of5:
Code 2of5 is a variable length symbology with
an optional check digit and non printable start
and stop characters. The following characters
are supported:
• the digits 0 upto 9
The checksum is calculated as the sum modulo
10 of the numerical values of all the data
characters.
Industrial 2of5:
This symbology encodes a single digit in each
data symbol. Information is carried in the bars
only.
Interleaved 2of5:
This symbology encodes a pair of digits in each
symbol, the number of digits are therefore
always an even number. Information is carried
in the bars and spaces. The start and stop
pattern is not unique inside the code. It is
therefore essential to use the fixed length
option to prevent partial reads.
S-Code:
This symbology encodes like Interleaved 2of5
but encodes the last data character as
Industrial 2of5. The number of data digits is
therefore always an odd number.
Information is carried in the bars and the
spaces.The start and stop pattern is not unique
inside the code. It is therefore essential to use
the fixed length option to prevent partial reads.
Matrix 2of5:
This symbology encodes 1 digit in each
character, the number of digits can therefore be
an odd or an even number. Information is
carried in the bars and spaces.
Chines Post Matrix 2of5:
This symbology is a variant of Matrix 2of5. To
assure proper reads, check the options and
setting for (Matrix) 2of5.
For string format of the supported symbologies
see figure 3.27.
Options for code 2of5:
• disable transmission of the check digit
• enable check digit check
• selection of the minimum number of data
characters
• disable space check for industrial 2of5
• transmit S-Code as Interleaved 2of5
Minimum data characters:
Code 2of5 are checked for a minimum of 1, 3 or
5 characters as set by the user. If the number of
characters in the label is less then the number
set, the label will be rejected. If the fixed length
option is used for a Code 2of5 type label, than
such label will additionally be checked for fixed
length.
Space check:
This option enables the reading of Industrial
2of5 labels with a large or irregular spacing.
Transmit S-Code as Interleaved 2of5:
This option enables to transmit S-Code as
Interleaved 2of5 by adding a leading zero.
