Using ADF Bar Codes
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 the Begin New Rule bar code on page 15-8.
• 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”). These options are described in Criteria on page 15-11.
• Actions. Scan all actions related to, or affecting, these criteria. The actions of a rule specify how to format the data for
transmission. These options are described in ADF Bar Code Menu Example on page 15-4.
• Save the Rule. Scan the Save Rule bar code on page 15-8. This places the rule in the “top” position in the rule buffer.
• Some special-purpose bar codes can be useful to correct errors during this process:
Erase Criteria and Start Again, Erase Actions and Start Again, Erase Previously Saved Rule, etc.
Criteria, actions, and entire rules may be erased by scanning the appropriate bar code (see page 15-9).

ADF Bar Code Menu Example
This section provides an example of how ADF rules are entered and used 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 PC 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 manufacturer ID code.
The following rules need to be entered:
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, follow the steps below:
