and the cashier will key the price manually.
To implement this, you would first enter an ADF rule that applies to 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.
To switch between the two sets of rules, a “switching rule” must be programmed. This rule
specifies what type of bar code must be scanned to switch between the rule sets. For
example, in the case of the “sale” rule above, 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.
The switching back to normal rules can also be done in the “sale” rule. For example, the
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, turn off rule set 1.
It is recommended that you scan the Disable All Rule Sets bar code on page 13-11 after
programming a rule belonging to an alternate rule set.
In addition to enabling and disabling rule sets within the rules, you can enable or disable
them by scanning the appropriate bar codes on
13-11 .
