Rockwell Automation 2755 Enhanced Decoder Series B - Manual (Page 144)

10–9 Configuration: Host Message Replacement Rules
Publication 2755-833
Note: If any rule is enabled for a given source, then all data from
that source will pass through the rules. For example, if any rule is
enabled for AUX data, then all AUX data will pass through the rules.
Therefore, if you construct a rule with Scanner A as the source, and
establish no rule for Scanner B, then all data from Scanner A will
pass through the rules, while the data from Scanner B will not. In
that case, a no-read from Scanner A would be represented by the
appropriate no-read replacement string. A no-read from Scanner B
(in Independent Mode) would be represented by the default no-read
string. Use “A|B” as the source if you want the rule to apply to both
scanners, or whenever Scanner B is set to coordinated mode.
When AUX is selected as the source, the rule processor ignores that
rule’s Host Field Number, Symbol Number, and Symbology
parameters.

Selects the symbology to which the host message replacement rule
should be applied. The default value is Any. Pharma–Code is
available only on decoders equipped with the Pharma–Code option.

All
Determines the bar code symbol to which the displayed rule should
be applied. 1 would apply the rule only to the first symbol read, 2 to
the second symbol, and so on up through 16. The default value of All
applies the rule to all symbols read.
Use All in raster scanner applications, or whenever you are uncertain
of the order in which the symbols will be read.
