Symbologies376 Gryphon™ I GD4100/GM4100Code 4 and Code 5 Common Configuration ItemsThe following options apply to both Code 4 and Code 5 symbologies.Code 4 and 5 Decoding LevelDecoding Levels are used to configure a barcode symbology decoder to be very aggressive tovery conservative depending on a particular customer’s needs.• Choosing Level 1 results in a very conservative decoder at the expense of not being able toread poorly printed or damaged labels.• Choosing Level 5 results in a very aggressive decoder. This aggressive behavior allowsdecoding of poorly printed and damaged labels at the expense of increasing the likelihoodof decoding errors.• Choosing Level 3, which is the default setting, allows the majority of product labels to bedecoded.There are many factors that determine when to change the decoding level for a particularsymbology. These factors include spots, voids, non-uniform bar/space widths, damaged labels,etc. that may be experienced in some barcode labels. If there are many hard to read or damagedlabels that cannot be decoded using a conservative setting, increase the decoding level to bemore aggressive. If the majority of labels are very good quality labels, or there is a need todecrease the possibility of a decoder error, lower the decoding level to a more conservative level.NOTEThis configuration item applies to Code 4 and Code 5.
