Inateck BCST-33 - Checksum Verification

41
3.8.2. Checksum Verication
Checksum character is not enforced to be included in the MSI data. If checksum
character is included, it should be the last one or two characters of the barcode
data. As a calculate value based on all the data, Checksum character is used to check
whether the data is correct or not.
Thus, if the scanner is set to “Do Not Verify”, which is default, then the scanner will
read and output all the barcode data.
If the scanner is set to "Verify with one digit Checksum Character", and the scanner
will check the data based on the last character of the barcode data. And It will not be
able to read MSI barcode without checksum character or MSI barcode with two digits
checksum character.
If the scanner is set to "Verify with two digits Checksum Character", and the scanner
will check the data based on the last two characters of the barcode data. And it will
not be able to read MSI barcode without checksum character or MSI barcode with
one digit checksum character.
If the scanner is set to "Verify with Output Checksum Character", and the scanner will
check the data based on the last one or two characters of the barcode data. If the
check
passes, the scanner will output the checksum characters as the last one or two
characters of normal data. Inateck BCST-33 takes outputting checksum characters as
default.
If the scanner is set to "Verify without Output Checksum Character", the scanner will
not output the checksum character.
