Rules for Output Filter Configuration
Output Filter Configuration Rule # 1
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.
Output Filter Configuration Rule # 2
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.
Output Filter Configuration Rule # 3
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 has settings for the following four
parameters:
Symbology
,
Symbol Length
,
Data
, and
Configuration Database
Number.
