Creating ADF Rules
When programming a rule, make sure the rule is logically correct. Plan ahead before scanning.
To program each data formatting rule:
• Start the Rule. Scan Begin New Rule on page 15-8 .
• Specify Criteria. Scan the bar codes for all pertinent criteria. Criteria can include code type (e.g., Code 128),
code length, or data that contains a specific character string (e.g., the digits “129”). See
Criteria on page
15-11 for options.
• Select Actions. Scan all actions related to, or affecting, these criteria. The actions of a rule specify how to
format the data for transmission. See
Actions on page 15-27 .
• Save the Rule. Scan Save Rule on page 15-8 . This places the rule in the “top” position in the rule buffer.
To erase criteria, actions, and entire rules, scan the appropriate bar code on page 15-9 .
Beeper Definitions on page 2-2 guide through the programming steps.
ADF Programming Example
This section provides an example of how to enter ADF rules to use for scan data.
An auto parts distribution center wants to encode manufacturer ID, part number, and destination code into their
own Code 128 bar codes. The distribution center also has products that carry UPC bar codes, placed there by the
manufacturer. The Code 128 bar codes have the following format:
MMMMMPPPPPDD
Where: M = Manufacturer ID
P = Part Number
D = Destination Code
The distribution center uses a host computer with dedicated control characters for manufacturer ID <CTRL M>,
part number <CTRL P>, and destination code <CTRL D>. At this center the UPC data is treated as a manufacturer
ID code.
The center programs the following rules:
• When scanning data of code type Code 128, send the next 5 characters, send the manufacturer ID key
<CTRL M>, send the next 5 characters, send the part number key <CTRL P>, send the next 2 characters,
send the destination code key <CTRL D>.
• When scanning data of code type UPC/EAN, send all data, send the manufacturer ID key <CTRL M>.
To enter these rules, see the following section.
