Message Length
You are able to set the valid reading length of some of the barcode symbologies.
If the data length of the scanned barcode doesn’t match the valid reading length,
the image scanner will issue an error beep. You may wish to set the same value
for minimum and maximum length to force the image scanner to read fixed length
barcode data. This helps reduce the chances of a misread.
EXAMPLE: Decode only those barcodes with a count of 9-20 characters.
Min. length = 09 Max. length = 20
EXAMPLE: Decode only those barcodes 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 barcodes included in the explanation of the symbology, then scan the
digit value of the message length and Save barcodes 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.
