Values of n: 1, 2, 4, 5, 6
Values of i: 1 . . . 32
Values of j: 1 . . . 32
n – Code type to be length checked
i – The new minimum length for the code type (i must be less than or equal to
j). For I 2 of 5, this must be an even number betwen 4 and 32.
j – The new maximum length for the code type. For 1 2 of 5, this must be an
even number between 4 and 32.
Note: The commas must be included as shown above.
Minimum and Maximum Length Example
To configure your decoder to check for a minimum of 6 and maximum of 10
characters in a Code 39 symbol, enter:
Esc – y 1, 6, 10 U
The length checking for Interleaved 2 of 5 is different from the length
checking for the other codes. Since the I 2 of 5
symbology decodes in pairs, even lengths should be specified.
Note: Select the minimum and maximum length with the Esc –y <n>,
<i>, <j> U escape sequence.
