14 - 4 Symbol LS2208 Product Reference Guide
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.
The “sale” rule may look like:
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 to normal 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.
It is recommended that you scan
Disable All Rule Sets 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, enable or disable them by scanning the appropriate
bar codes
.
Rules Hierarchy (in Bar Codes)
The order of programming individual rules is important. Program the most general rule first.
All programmed rules are stored in a buffer. As they are programmed, they are stored at the top of a rules list. If you
create three rules, the list is configured as follows:
Third Rule
Second Rule
First Rule
When scanning data, the rules list is checked from top to bottom to determine if the criteria matches (and therefore,
if the actions occur). Input is modified into the data format specified by the first matching set of criteria it finds. Be
sure to program the most general rule first.
For example, if the THIRD rule states:
When scanning a bar code of any length, send all data, then send the ENTER key.
