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.
