Chapter 14 Advanced Data Formatting
Introduction
Advanced Data Formatting (ADF) is a means of customizing data before transmission to the host device. Edit scan
data to suit particular requirements.
data to suit particular requirements.
To implement ADF, scan a related series of bar codes, which begin on
, or install the 123Scan utility (see
) which programs the scanner with ADF rules.
Rules: Criteria Linked to Actions
ADF uses rules to customize data. 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.
rule may consist of single or multiple criteria applied to single or multiple actions.
For instance, a data formatting rule could be:
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.
send all data up to X,
send a space.
Scanning a Code 39 bar code of 1299X1559828 transmits the following: 00001299<space>. If you scan a Code 39
bar code of 1299X15598, this rule is ignored because the bar code did not meet the length criteria.
bar code of 1299X15598, this rule is ignored because the bar code did not meet the length criteria.
The rule specifies the editing conditions and requirements before data transmission occurs.
NOTE
If using the wand interface with the scanner, you cannot use ADF rules to format data.
