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 to the normal situation, such as:
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.
Then enter the "sale" rule, such as:
Scan Rule Belongs to Set 1. 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.
To switch between the two sets of rules, program a "switching" rule that specifies what type
of bar code must be scanned to switch between the rule sets. For example, in the case of
the "sale" rule, the rule programmer wants the cashier to scan the bar code "M" before a
sale. To do this, a rule can be entered as follows:
When scanning a bar code of length 1 that begins with "M", select rule set
number 1.
Another rule could be programmed to switch back:
When scanning a bar code of length 1 that begins with "N", turn off rule set
number 1.
