SE4400 Imager Barcodes 215
E-SW-BLUESCANPG-A Bluetooth Ring Scanner Guide
Set Length(s) for Code 39
L1 Parameter Default Value: 2
L2 Parameter Default Value: 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” at the end of the “Appendix”.
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 barcode and then “1” and
“4” barcodes using the “Imager Keypad Number Symbols” at the end of this chapter. Single digits
must be preceded by a zero.
To begin setting one discrete length, scan this One Discrete Length barcode:
Next, scan two numeric barcodes 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 barcode and
then “0”, “2”, “1” and “4” barcodes using the “Imager Keypad Number Symbols” at the end of
this chapter.
To begin setting two discrete lengths, scan this Two Discrete Lengths barcode:
Next, scan four numeric barcodes 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.
