MSI Check Digits
Parameter # 50 (SSI # 32h)

is optional. If the MSI codes include two check digits, scan the Two MSI Check Digits barcode to enable
verification of the second check digit.

1 - This is for MSI barcodes with one check digit. This is the default.
2 - This is for MSI barcodes with two check digits.
