Alternate Rule Sets — cont.
But, when there is a sale, you may want to send only the following:
24 (class key)
56712437 (stock key)
and the cashier will key the price manually.
To implement this, you would first enter an ADF rule that applies to the normal situa-
tion. This rule may look like this:
When scanning a barcode 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 barcode 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 barcode 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 barcode “M” before a sale. To do this, a rule can be entered as follows:
When scanning a barcode of length 1 that begins with “M”, select rule set number
1.
Another rule could be programmed to switch back.
When scanning a barcode of length 1 that begins with “N”, turn off rule set num-
ber 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 barcode 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 barcode:
Disable All Rule Sets on page 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 barcodes beginning on
page 11
