15 - 2 Symbol DS3478 Product Reference Guide

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 

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 

 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 

.

Save the Rule. Scan 

. 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

 guide through the programming steps.

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.
