To implement this, first enter an ADF rule that applies to the normal situation, 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, send the data that remains, send the Enter key.
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:
Scan Rule Belongs to Set 2. 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.
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 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, a rule can be entered as follows:
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.
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.
characters, send the stock key, turn off rule set 1.
For optimal results, scan
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 on

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:
If you create three rules, the list is configured as follows:
Third Rule
Second Rule
First Rule
When you scan 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.
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.
And the SECOND rule states:
When scanning a Code 128 bar code of length 12, send the first four characters, then send the ENTER key,
then send all remaining data.
then send all remaining data.
and you scan a Code 128 bar code of length 12, the THIRD rule applies, and the SECOND rule appears to not

Note that using the standard data editing functions also creates ADF rules. Scan options are entered as ADF
rules, and the hierarchy mentioned above also applies to them. For the linear imager scanner, this applies to
prefix/suffix programming in the parameter
rules, and the hierarchy mentioned above also applies to them. For the linear imager scanner, this applies to

These rules reside in the same “rule list” as ADF Rules, so the order you create them is also important.
