Introduction
Advanced Data Formatting (ADF) is a means of customizing data before transmission to the host device. Scan data can be edited to
suit particular requirements.
ADF can be implemented through scanning a related series of bar codes, which begin on page
, or by installing the 123Scan utility
(see
) which allows the digital scanner to be setup and programmed with Advanced Data Formatting (ADF) Rules.
Avoid using ADF formatting with bar codes containing more than 60 characters. To add a prefix or suffix value for such bar codes, use
Add Prefix/Suffix setting. Using ADF with longer bar codes transmits the bar code in segments of length 252 or less (depending on
the host selected), and applies the rule to each segment
If using the Wand interface with the digital scanner, in order to use ADF rules to format data, first enable
Convert All Bar Codes to Code 39 on page 10-8
.
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.
