Check Digit Output (Interleaved 2 of 5)
Definition: When enabled, a check digit character is sent along with the bar symbol
data for added data security.
Serial Cmd: <K472,status,check digit
#1,symbol length #2>
Default: Disabled
Options: 0 = Disabled
Symbol Length #1 (Interleaved 2 of 5)
Definition: Allows user to define the symbol length. Because I 2/5 is a continuous
symbol, it is prone to substitution errors. Hence, a symbol length must be
defined and a bar symbol must contain an even number of digits.
Note: If start, stop or check digits are used, they are not included in
the symbol length count.
Usage: With I 2/5, two symbol lengths can be defined. When using only one
symbol length in an application, setting Symbol Length #2 to 0 (zero)
to ensure data integrity is recommended.
Serial Cmd: <K472, status,check digit status,check digit
#1,symbol length #2>
Default: 10
Options: 2 to 64
Since I 2/5 characters are paired, symbol length must be set to an even
number. If Check Digit is enabled, add 2 to your symbol length. For
example, if your symbol is 10 characters plus a check digit, then enable
Symbol Length for 12.
Note: Typically, when printing an I 2/5 symbol with an odd number of
digits, a 0 will be added as the first character.
