4 Advance Data Formatting Advanced Data Formatting (ADF) is a means of customizing data before transmission to your USB host device. Scan data can be edited to suit your particular requirements. ADF can be implemented through scanning a related series of bar codes, which allows the scanner to be setup and programmed with Advanced Data Formatting (ADF) Rules. Rules: Criteria Linked to Actions In ADF, data is customized through rules. These rules perform detailed actions when the data meets certain criteria. One rule may consist of single or multiple criteria applied to single or multiple actions. For instance, a data formatting rule could be the following: Criteria: When scan data is Code 39, length 12, and data at the start position is the string "129", Actions: pad all sends with zeros to length 8, send all data up to X, send a space. If a Code 39 bar code of 1299X1559828 is scanned, the following is transmitted: 00001299. If a Code 39 bar code of 1299X15598 is scanned, this rule is ignored because the length criteria has not been met. The rule specifies the editing conditions and requirements before data transmission occurs. Programming Reference Guide 4-1

Advance Data Formatting
Advanced Data Formatting (ADF) is a means of customizing data
before transmission to your USB host device. Scan data can be
edited to suit your particular requirements.
ADF can be implemented through scanning a related series of bar
codes, which allows the scanner to be setup and programmed
with Advanced Data Formatting (ADF) Rules.
Rules: Criteria Linked to Actions
In ADF, data is customized through rules. These rules perform
detailed actions when the data meets certain criteria. One rule
may consist of single or multiple criteria applied to single or
multiple actions.
For instance, a data formatting rule could be the following:
Criteria:
When scan data is Code 39, length 12, and data at
the start position is the string “129”,
Actions:
pad all sends with zeros to length 8, send all data up
to X, send a space.
If a Code 39 bar code of 1299X1559828 is scanned, the following
is transmitted: 00001299<space>. If a Code 39 bar code of
1299X15598 is scanned, this rule is ignored because the length
criteria has not been met.
The rule specifies the editing conditions and requirements before
data transmission occurs.
