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.
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 the standard data editing functions are used. Scan options are
entered as ADF rules, and the hierarchy mentioned previously also applies to them. For the scanner, 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 never goes into the default rules.
Special Considerations for Multipoint Networks
ADF rules scanned by an individual scanner are NOT broadcast to other scanners in the piconet, as are other
parameters; however, ADF rules that 123Scan generates ARE broadcast to all scanners in the piconet. 123Scan
rules transmitted from the base are stored at the BEGINNING of the ADF rule buffer, regardless of the presence of
existing rules, while rules scanned by the scanner are appended to the existing buffer. For this reason, transmit
rules to be shared by all scanners from 123Scan FIRST. Then, scan rules to customize an individual scanner after
123Scan rules are transferred.
