3.4.3. Checksum Verication
Checksum character is not enforced to be included in the data of Code 39. If
checksum character is included, it should be the last character of the barcode data.
As a calculate value based on all of the data, Checksum character is used to check
whether the data is correct or not.
If the scanner is set to "Do Not Verify”, which is the default, then the scanner will read
all the barcode data.
If the scanner is set to "Verify with Output Checksum Character", and the scanner will
check the data based on the last character of the barcode data. If the check passes,
It will read and output the Checksum Character as the last character of normal data;
However it will not be able to read Code 39 without checksum character.
If the scanner is set to "Verify without Output Checksum Character", and the scanner
will check the data based on the last character of the barcode data. If the check
passes, It will read but will NOT output the Checksum Character as the last character
of normal data; However it will not be able to read Code 39 without checksum
character.
For example, Operations are as below if you want to set Verify with Output Checksum
Character:
1. Read the "Enter Setup" barcode;
2. Read the "Verify with Output Checksum Character" barcode;
3. Read the "Exit with Save" barcode.
