Decoded (Internal) Scanners
Interleaved 2 of 5
Transmit Check Digit
If this parameter is enabled, the check digit is included with the bar code data.
Check Digit Algorithm
When the Two MSI Plessey check digits option is selected, an additional verification is re-
quired to ensure integrity. Double-tapping on this parameter displays a dialog box n which
you can choose the algorithm to be used: MOD 10/MOD 11 or MOD 10/MOD 10.
Length Restriction
Refer to “Length Restriction” on page 142 for details.
Add/Remove Data
Refer to “Add/Remove Data” on page 142 for details.
5.13.2.14 Interleaved 2 of 5
Enabled
Set this parameter to on to enable “Interleaved 2 of 5”.
Set Length L1 And Set Length L2
Lengths for “Interleaved 2 of 5” can be set for Any length, Length within a range, One dis-
crete length or Two discrete lengths. The length of a code refers to the number of characters
(i.e., human readable characters), including check digit(s).
Double-tapping on this parameter displays a dialog box labelled Set Code Lengths where
you can define the code length that will be recognized by your scanner.
Choosing One discrete length allows you to decode only those codes containing a selected
length. Choosing Two discrete lengths allows you to decode only those codes containing two
selected lengths. Length within a range allows you to decode a code type within a specified
range from 4 to 14.
Check Digit Verification
When enabled, this parameter checks the integrity of an I 2 of 5 symbol to ensure it complies
with a specified algorithm—either USS (Uniform Symbology Specification) or
OPCC (Optical Product Code Council).
Note: If Two check digits is selected, an MSI Plessey “Check Digit Algorithm: must also
be selected. See below for details.
