When programming a rule, make sure the rule is logically correct. Plan ahead before you start scanning.

To program each data formatting rule: 

Start the Rule. Scan the 

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 

.

Actions. Scan all actions related to, or affecting, these criteria. The actions of a rule specify how to format 
the data for transmission. See 

.

Save the Rule. Scan the 

 bar code on page 14-8. This places the rule in the “top” position in the 

rule buffer.

To correct errors during this process, erase criteria, actions, and entire rules by scanning the appropriate bar 
code under 

 guide through the programming steps. For more information on scanning, see 

.

This section provides an example of how to enter ADF rules 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 must 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, use the following steps:
