MSI/Plessey Options
The MSI/Plessey symbology has the following programmable
features:
•
Check Digit
• Label Length Format
• Read Verification
Check Digit Check Digit calculates the Check Digit(s) to verify the labels contents

minimum label length to 16. Set Minimum Length as high as your
application allows.

that the scanner will recognize. The minimum label length for
this symbology must be between 04 and 16.

lengths.
If you select fixed length format, there are three bar code labels for pro-
gramming your scanner to read either one or two fixed lengths. The
labels are:
MSI/Plessey options are all applicable only to the scanner, with
the exception of Check Digit Transmission, which applies only
to the Base Station.
