MSI/Plessey Check Character Calculation
Enables/disables calculation and verification of optional MSI/Plessey
check characters.
To set this feature:
1. Scan the SWITCH bar code.
2. Scan either the enable or disable bar code below. You’ll need to cover
any unused bar codes on this and the facing page to ensure that the
scanner reads only the bar code you intend to scan.
3. Complete the programming sequence by scanning the SWITCH
bar code.
MSI/PLESSEY CHECK CHARACTER CALCULATION = DISABLE
MSI/PLESSEY CHECK CHARACTER CALCULATION = ENABLE
NOTE
If check character calculation is disabled, the risk is increased that a
misread can occur. When disabled, any check characters in a bar
code are treated as data characters.
