9.2.5 Resolution of Inconsistencies

Three types of inconsistencies could arise in the assignment of symbology options. The

decoder has pre-defined strategies to resolve these inconsistencies: If UPCE_as_EAN13

is true, then UPCE_as_UPCA is ignored.

If symbology conversion is selected but the target symbology is not enabled, then the

decoder still outputs the symbol in the target symbology. For example, suppose UPC-E

is enabled and UPCE_as_EAN13 is true but EAN-13 is disabled. All UPC-E symbols will

be shown as EAN-13 and EAN-13 options (if specified) will be applied. For the two

symbologies that have optional check digits, Code39 and Interleave 2 of 5, the decoder

will always transmit the check digit if the verification is disabled.
