Appendix C: Bar Code Settings

Decoded (Internal) Scanners

Interleaved 2 of 5

Check Digits

Double-tapping on this parameter displays a dialog box in which you can choose One or

Two check digit(s).

If this parameter is set to One, it is assumed that the last digit is a check digit. If “Check

Digits” is set to Two, it is assumed that the last two digits are check digits.

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 in 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 C-14 for details.

Add/Remove Data

Refer to “Add/Remove Data” on page C-14 for details.

C.2.15 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 bar codes of a specified

length. Choosing Two discrete lengths allows you to specify two lengths of bar codes that

may be decoded. Length within a range allows you to decode any bar code with a length

Note: If Two check digits is selected, an MSI Plessey “Check Digit Algorithm” must also

be selected. See below for details.
