Message Length
You are able to set the valid reading length of some of the bar code symbologies.
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 included in the explanation of the symbology, then scan the
digit value of the message length and
Save bar codes on the Programming Chart
inside the back cover of this manual. The minimum and maximum lengths and
the defaults are included with the respective symbologies.
