Chapter 15 Advanced Data Formatting

Introduction

Advanced Data Formatting (ADF) is a means of customizing data before transmission to the host device. Use ADF
to edit scan data to suit particular requirements.

To implement ADF, scan a related series of bar codes, which begin on

page 15-7

, or install the 123Scan utility (see

Chapter 12, 123Scan

) which allows programming the digital scanner with 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

Prefix/Suffix Values on page 4-17

. 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

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.

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.

Scanning a Code 39 bar code of 1299X1559828 transmits the following: 00001299. If you scan a Code 39
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.
