Advanced Data Formatting 14-3
Introduction
Advanced Data Formatting (ADF) is a means of customizing data before transmission to the host
device. Scan data can be edited to suit the particular requirements.
ADF can be implemented through scanning a related series of bar codes, which begin on page 14-9 ,
or by installing the 123Scan utility (see Chapter 11, 123 Scan ) which allows the scanner to be setup
and programmed with Advanced Data Formatting (ADF) Rules.
If the Wand Emulation interface is being used with the scanner, it is not
possible to use ADF rules to format the data unless convert all Bar Codes to
Code 39 is enabled on page 9-10.
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.
Using ADF Bar Codes
When a rule is programed, make sure the rule is logically correct. Plan ahead before starting to scan.
To program each data formatting rule:
• Start the Rule . Scan the Begin New Rule bar code on page 14-9.
