Start the Rule. Scan the
•
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
11-11.
•
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

ADF Bar Code Menu Example
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>. The center treats the UPC data as a 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:
