Data in a Code 11 barcode may not include the checksum code. If there is, the checksum
code is the last one or two digit(s) of the data output. The checksum code is the value added
from all data collected, to check if the data is correct.
After you set the "Code 11 without Checksum" function, the scanner can recognize all Code

After you set the "Code 11 with 1-digit Checksum" function, the scanner will take the last one
digit of the data as checksum and won't be able to read Code 11 without checksum or Code
11 with 2-digit checksum.

digits of the data as checksum and won't be able to read Code 11 without checksum or Code
