Set Lengths for Discrete 2 of 5
L1 Default: 1 Discrete Length: 12
L2 Default: 12
Lengths for D 2 of 5 may be set for:
any length,
one or two discrete lengths,
or lengths within a specific range.
The length of a code refers to the number of characters, including check digits, the code contains.
See the table titled ASCII Character Equivalents (page 9-2).
Note: Due to the construction of the D2 of 5 symbology, it is possible for a scan line covering only a portion of the code to
be interpreted as a complete scan, yielding less data than is encoded in the bar code. To prevent this, select specific
lengths (using D2 of 5 – One Discrete Length and D 2 of 5 Two Discrete Lengths) for D 2 of 5 applications.
Note: One Discrete Length (Parameter L1)
This option decodes only those codes containing a selected length. For example, when you want to scan only D 2 of 5
symbols containing 14 characters, scan the “D 2 of 5 One Discrete Length” bar code and then “1” and “4” bar codes
using the Imager Keypad Number Symbols (page 5-81).
To begin setting one discrete length, scan this D 2 of 5 One Discrete Length bar code:
Next, scan two numeric bar codes that correspond to the desired value. Single digit numbers must have a leading
zero. To correct an error or to change a selection, scan Cancel on the “Imager Keypad Number Symbols” page.
Two Discrete Lengths (Parameter L2)
This option decodes only those codes containing two selected lengths. For example, when you want to scan only D 2
of 5 symbols containing 2 or 14 characters, scan the “D 2 of 5 Two Discrete Lengths” bar code and then “0”, “2”, “1” and
“4” bar codes using the Imager Keypad Number Symbols (page 5-81).
To begin setting two discrete lengths, scan this D 2 of 5 Two Discrete Lengths bar code:
Next, scan four numeric bar codes that correspond to the desired value. Single digit numbers must have a leading
zero. To correct an error or to change a selection, scan Cancel on the Imager Keypad Number Symbols page.
