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 12-5

.

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 12-8

.

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 12-2

.

Save the Rule. Scan the

Save Rule

bar code on

page 12-5

. 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 12-6

).

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 , part number
, and destination code . 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 M>, send the next 5 characters, send the part number key , send the next 2 characters, send the
destination code key .

When scanning data of code type UPC/EAN, send all data, send the manufacturer ID key .

To enter these rules, follow the steps below:
