Advanced Data Formatting (ADF)
If a Code 128 bar code of length 12 were scanned, the THIRD rule would be in effect. The
SECOND rule would appear to not function.
Note also that ADF rules are actually created when you use the standard data editing
functions. Scan options are entered as ADF rules, and the hierarchy mentioned above also
applies to them. For the P 300, this applies to prefix/suffix programming in the parameter
Scan Data Transmission Format.
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. Default rules can be disabled by entering the following general rule in
the user programmable buffer:
When receiving scan data, send all data.
Since this rule always applies, ADF will never go into the default rules.
