Default Rules; Adf Bar Codes - Symbol LS4208 Reference Manual

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 that using the 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 Symbol LS4208, this applies to prefix/suffix
programming in Scan Data Transmission Format on page
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 enters the default rules.
