Rules Hierarchy (In Bar Codes); Default Rules - Motorola LS3408-FZ20005 Product Reference Manual

Rules Hierarchy (in Bar Codes)

The order of programming individual rules is important. Program the most general rule first.
All programmed rules are stored in a buffer. As they are programmed, they are stored at the "top" of a rules list. If
you created three rules, the list is configured as follows:
Third Rule
Second Rule
First Rule
When data is scanned, the rules list is checked from top to bottom to determine if the criteria matches (and
therefore, if the actions occur). Input is modified into the data format specified by the first matching set of criteria it
finds. Be sure that the most general rule is the first one programmed.
For example, if the THIRD rule states:
When scanning a bar code of any length, send all data, then send the ENTER key.
and the SECOND rule states:
When scanning a Code 128 bar code of length 12, send the first four characters, then send the ENTER key,
then send all remaining data.
and you scan a Code 128 bar code of length 12, the THIRD rule applies, and the SECOND rule does not function.
Note also that using standard data editing functions also creates ADF rules. Scan options are entered as ADF
rules, and the hierarchy mentioned above also applies to them. For the scanner, this applies to prefix/suffix
programming in the parameter
These rules reside in the same "rule list" as ADF rules, so the order of their creation is also important.

Default Rules

Every unit has a default rule to send all scan data. Units with custom software may have one or more default rules
burned in. The rules hierarchy checks user programmable rules first, then the default rules. Disable default rules by
entering the following general rule in the user programmable buffer:
When receiving scan data, send all data.
Since this rule always applies, ADF never goes into the default rules.
