Advanced Data Formatting 14 - 5
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 do es not func tio n.
Note that using th e standard data editing functions also creates ADF rules. Scan o ptions are entered as ADF rules,
and the hierarchy mentioned above also applies to them. For the Symb ol LS4208, this applies to prefix/suffix
programming in Scan Data Transmission Format on page 13-4.
These rules reside in the same “rule list” as ADF rules, so the order of their creation is also importan t.
Default Rules
Every unit has a default rule to send all scan data. Unit s with custom software may have one or more default rule s
burned in. The rules hi erarchy checks user programma ble rules first, then the default rules. Disable default rules by
entering the following gener al rule in the user programmable buffer:
When receiving scan data, send all data.
Since this rule always applies, ADF never enters the default rules.
