Set Lengths for Code 39
L1 = Parameter #18, SSI #12h
L2 = Parameter #19, SSI #13h
The length of a code refers to the number of characters (that is, human readable characters), including check digits the code contains.
The following are length options for Code 39:
- One Discrete Length—decodes only Code 39 symbols containing a selected length.Example
To decode only Code 39 symbols with 14 characters, scan Code 39 - One Discrete Length, and then scan the numeric bar codes 1 and 4 from Numeric Bar Codes.
- Two Discrete Lengths—decodes only Code 39 symbols containing either of two lengths.Example
To decode only Code 39 symbols containing either 2 or 14 characters, scan Code 39 - Two Discrete Lengths, and then scan the numeric bar codes 0, 2, 1, and 4 from Numeric Bar Codes.
- Length Within Range—decodes only Code 39 symbols with a specific length range (2 to 55).Note
To decode only Code 39 symbols containing between 4 and 12 characters, scan Code 39 - Length Within Range, and then scan the numeric bar codes 0, 4, 1, and 2 from Numeric Bar Codes.
- Any Length—decodes only Code 39 symbols containing any number of characters within the capability of the scanner.
Enter a leading zero for single‑digit numbers. To correct an error or change the selection, scan the Cancel bar code in Numeric Bar Codes.
The following are length ranges:
- L1: 0 to 80
- L2: 0 to 80
Scan one of the following bar codes to set the length for Code 39. By default, this parameter is set to Length Within Range.
