Set Length(s) for Code 39
L1 Default: 2
L2 Default: 55
Lengths for Code 39 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. If Code 39 Full ASCII is
enabled, Length Within a Range or Any Length are the preferred options.
See the table titled ASCII Character Equivalents (page 6-1).
One Discrete Length (Parameter L1)
This option decodes only those codes containing a selected length. For example, when you want to scan only Code 39
symbols containing 14 characters, scan the following bar code and then “1” and “4” bar codes using the Imager
Keypad Number Symbols (page 4-81). Single digits must be preceded by a zero.
To begin setting one discrete length, scan this 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
Code 39 symbols containing 2 or 14 characters, scan the following bar code and then “0”, “2”, “1” and “4” bar codes
using the Imager Keypad Number Symbols (page 4-81).
To begin setting two discrete lengths, scan this 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.
Length Within Range
This option decodes a code type within a specified minimum and maximum range. For example, when you want to
scan only Code 39 symbols containing between 4 and 12 characters, scan the “Code 39 Length Within Range” bar
code and then “0”, “4”, “1” and “2” bar codes using the Imager Keypad Number Symbols (page 4-81).
To begin setting lengths within a range, scan this Length Within Range bar code:
Next, scan 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.
