Discrete 2 of 5
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 6 to 55.
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.
Note: If
Two check digits is selected, an MSI Plessey “Check Digit Algorithm”
must also be selected. See page 9-88.
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 required 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.

5.10.3.14 Discrete 2 of 5
Enabled
Set this parameter to on to enable “Discrete 2 of 5”.
Set Length L1 And Set Length L2
Lengths for “Discrete 2 of 5” can be set for Any length, Length within a range, One
discrete 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.
