But, when there is a sale, 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. 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, program a “switching rule” to specify the type of bar code to scan 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, enter the following rule:
When scanning a bar code of length 1 that begins with “M”, select rule set number 1.
Program another rule to switch back:
When scanning a bar code of length 1 that begins with “N”, turn off rule set number 1.
Or include the switching back rules in the “sale” rule:
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.
Motorola recommends scanning the Disable All Rule Sets bar code on page 14-8 after programming a rule
belonging to an alternate rule set.
In addition to enabling and disabling rule sets within the rules, also enable or disable them by scanning the
appropriate bar codes on page 14-8.
