Code 39 Check Character
No Check Character indicates that the 8680i reads and transmits bar code data
with or without a check character.
When Check Character is set to Validate, but Don't Transmit, the unit only reads
Code 39 bar codes printed with a check character, but does not transmit the check
character with the scanned data.
When Check Character is set to Validate and Transmit, the 8680i only reads Code
39 bar codes printed with a check character, and transmits this character at the
end of the scanned data. Default = No Check Character.
Code 39 Redundancy
If you are encountering errors when reading Code 39 bar codes, you may want to
adjust the redundancy count. Redundancy adjusts the number of times a bar code
is decoded before transmission, which may reduce the number of errors. Note that
the higher the redundancy count, the longer it will take to decode the bar code. To
adjust the redundancy, scan the Code 39 Redundancy bar code below, then scan a
redundancy count between 0 and 10 on the
page 235. Then scan the Save bar code. Default = 0.
