MSI Plessey Check Digits
Check digits placed at the end of the MSI Plessey bar code verify the integrity of the data. At least one check digit is
always required. Check digits are not automatically transmitted with the data.
Note: When Two Check Digits is selected, an “MSI Plessey Check Digit Algorithm” must also be selected.
Set the number of check digits to be included with the bar code by scanning either of the bar codes shown below.
Set Lengths for MSI Plessey
L1 Default: 06
L2 Default: 55
Lengths for MSI Plessey may be set for:
• any length,
• one or two discrete lengths,
• or lengths within a specific range.
The length of a code refers to the number of characters, including check digits, the code contains.
See the table titled ASCII Character Equivalents (page 9-2).
One Discrete Length (Parameter L1)
This option decodes only those codes containing a selected length. For example, when you want to scan only
MSI Plessey symbols containing 14 characters, scan the “MSI Plessey One Discrete Length” bar code and then
“1” and “4” bar codes using the
Keypad Number Symbols (page 4-72).
To begin setting one discrete length, scan this bar code:
Next, scan two numeric bar codes that correspond to the desired value. Single digit numbers must have a leading
zero. If you wish to change your number selection, scan Cancel on the Keypad Number Symbols page.
