The MSI barcode contains 1-digit compulsory checksum code. If there is a checksum code, it
will be the last 1 or 2 digit(s). The checksum is the value added from all data collected to check
if the data input is correct.
After you set the "MSI without Checksum" function, the scanner can recognize all regular MSI
barcodes. The default setting is "MSI without checksum".
After you set the "MSI with One-digit Checksum" function, the scanner will take the last digit
of the data as the checksum and won't be able to recognize MSI without checksum or with
2-digit checksum. The default setting is "MSI with One-digit Checksum".
