Set Lengths for MSI
L1 = Parameter #30, SSI #1Eh
L2 = Parameter #31, SSI #1Fh
The length of a code refers to the number of characters (that is, human readable characters), including check digits the code contains.
Due to the construction of the MSI symbology, it is possible for a scan line covering only a portion of the code to transmit as a complete scan, yielding less data than is encoded in the bar code. To prevent this, select specific lengths (Discrete 2 of 5 - One Discrete Length, Two Discrete Lengths) for MSI applications.
The following are length options for MSI:
- One Discrete Length—decodes only MSI symbols containing a selected length.Example
To decode only MSI symbols with 14 characters, scan MSI - One Discrete Length, and then scan the numeric bar codes 1 and 4 from Numeric Bar Codes.
- Two Discrete Lengths—decodes only MSI symbols containing either of two lengths.Example
To decode only MSI symbols containing either 2 or 14 characters, scan MSI - Two Discrete Lengths, and then scan the numeric bar codes 0, 2, 1, and 4 from Numeric Bar Codes.
- Length Within Range—decodes only MSI symbols with a specific length range (4 to 55).Example
To decode only MSI symbols containing between 4 and 12 characters, scan MSI - Length Within Range, and then scan the numeric bar codes 0, 4, 1, and 2 from Numeric Bar Codes.
- Any Length—decodes only MSI 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 MSI. By default, this parameter is set to Length Within Range.
