N-6 Output Filter Configuration
Each symbol that is decoded must match one of the filters before it can be saved to a read cycle record.
There is an exception to this rule, however, when the number of symbols required for a read cycle
exceeds the number of active filters. In such a case, unfiltered symbols can be placed into unfiltered
output positions.
For example, if the number of symbols required is 6 but there are only 4 active filters, the last 2 positions
can be filled by any (unfiltered) qualified symbol.
The same filter setup can be used multiple times.
For example, filters 1, 2, and 3 can be set up to filter Data Matrix symbols, and the output will occur in
the order the symbols are decoded.
All qualified symbols will be sorted and output in the matching filter position. If a symbol matches filter 3,
it will be output as the third symbol. If a filter does not have a matching qualified symbol, a No-Read
message will be output in place of the symbol (assuming the No-Read message is enabled).
For example, if there is not a symbol that meets filter 3’s requirements, then a No-Read message will be
output in the third output position.
Definition:
Output filtering is a method of providing a set of good read qualifiers and also providing
ordered output. There is a filter for up to the first 10 positions in a multisymbol output.
The first filter corresponds to the first symbol output at the end of the read cycle. Each
filter has settings for the following four parameters:
Symbology
,
Symbol Length
,
Data
,
and
Configuration Database Number
.
