Using ADF Bar Codes

When programming a rule, make sure the rule is logically corre ct. Plan ahead before you start scanning.
To program each data formatting rule:
•
Start the Rule . Scan the Begin New Rule bar code on page 14-8.
•
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”). See Criteria on p age 14-11.
•
Actions. Scan all actions related to, or affecting, these criteria. The actions of a rule specify how to format
the data for transmission. See Actions on page 14-23.
•
Save the Rule. Scan the Save Rule bar code on page 14-8 . This places the rule in the “top” position in the
rule buffer.
•
To correct errors dur ing th is proce ss, erase criteria , actions, a nd entire ru les by scanning the appr opriate bar
code under Erase on page 14-9.
Beeper Definitions on page 2-2 guide through the programming steps. For more information on scanning, see
Chapter 2, Scannin g.

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 distributio n 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 character s 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 dat a of code type Code 128, send the next 5 characters, send the manufactur er 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:
