Rules
Advanced Data Formatting
Advanced Data Formatting (ADF) is a means of customizing data before transmission to
your host device. Scan data can be edited to suit your particular requirements.
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:
If a Code 39 barcode of 1299X1559828 is scanned, the following is transmitted:
00001299<space>. If a Code 39 barcode 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 oc-
curs.
NOTE
If you are using the Wand interface with your scanner, you will not be
able to use ADF rules to format your data.
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.
