Check Character
No Check Character indicates that the scanner 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 will only
read Code 39 bar codes printed
with
a check character, but will not transmit the
check character with the scanned data.
When Check Character is set to Validate and Transmit, the scanner will only
read Code 39 bar codes printed with a check character, and will transmit this
character at the end of the scanned data.
Default = No Check Character.
Message Length
The message length selection is used to set the valid reading length of the bar
code. If the data length of the scanned bar code doesn’t match the valid reading
length, the scanner will issue an error beep. You may wish to set the same value
for minimum and maximum length to force the scanner to read fixed length bar
code data. This helps reduce the chances of a misread.
EXAMPLE:Decode only those bar codes with a count of 9-20 characters.
Min. length = 09 Max. length = 20
EXAMPLE:Decode only those bar codes with a count of 15 characters.
Min. length = 15 Max. length = 15
For a value other than the minimum and maximum message length defaults,
scan the bar codes below, then scan the 2-digit value and Save bar codes on the
Programming Chart inside the back cover. Minimum and Maximum
lengths = 0-48.
