Symbologies
Symbol Length #1 (Interleaved 2 of 5)
Symbol Length #2 (Interleaved 2 of 5)
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.
Definition:
Allows user to define the symbol length. Because I 2/5 is a continuous
symbology, it is prone to substitution errors. Hence, a symbol length must be
defined and a bar code symbol must contain an even number of digits.
Note: If a start, stop or check digits are used, they are not included in the
symbol length count.
Serial Cmd:
< K472, status,check digit status,check digit output, symbol length
#1 ,symbol length #2>
Default: 10
Options:
2 to 128, even.
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#1 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.
Note: If both Symbol Length # 1 and Symbol Length # 2 are set to 0, then
I–2/5 will be variable.
Usage:
If using a second symbol, a zero or any even symbol length from 2 to 64
may be specified. If not using a second symbol, set Symbol Length #2 to 0
to ensure data integrity.
Definition: Allows user to define a second symbol length for Interleaved 2 of 5.

Default: 6
Options:
2 to 128, even.
Since Interleaved 2 of 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.
Note: If both Symbol Length #1 and Symbol Length #2 are set to 0, then
I–2/5 will be variable.
