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
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
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
To correct any errors, see
ADF Bar Code Menu Example
This section provides an example of how to enter and use 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:
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
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
<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 steps.
Begin New Rule on page
