Advanced Data Formatting (ADF)

Alternate Rule Sets

ADF rules may be grouped into one of five alternate sets that can be turned on
and off when needed. This is useful when you want to format the same
message in different ways. For example, a Code 128 bar code contains the
following information:
Class (2 digits), Stock Number (8) digits, Price (5 digits)
This bar code might look like this:
245671243701500
where:
Class = 24
Stock Number = 56712437
Price = 01500
Ordinarily you would send this data as follows:
24 (class key)
56712437 (stock key)
01500 (enter key)
But, when there is a sale, you may want to send only the following:
24 (class key)
56712437 (stock key)
and the cashier keys the price manually.
To implement this, first enter an ADF rule that applies in the normal situation.
This rule may look like this:
When scanning a bar code of length 15, send the next 2 characters, send the
class key, send the next 8 characters, send the stock key, send the data that
remains, send the Enter key.
The "sale" rule may look like this:
When scanning a bar code of length 15, send the next 2 characters, send the
class key, send the next 8 characters, send the stock key.
