Select the number of master symbols you want to create.

Decide which way you want to enter your master symbol(s):

data >.
(b) Send a <G> (Read Next Symbol as Master Symbol) command.
(c) Enable the New Master Pin command and activate the discrete input to store the
next symbol read as the master symbol.
Definition: Matchcode
allows the user to store master symbol data in the reader’s
memory, compare that data against other symbol data, and define how
symbol data and/or discrete signal output will be directed.
A master symbol database can be set up for up to 10 master symbols.
Note: Matchcode
will function with multiple symbols; however, if
Matchcode
Type
is set to
Sequential
or if
Triggering Mode
is set to
Continuous Read 1
Output
, the reader will behave as if

were set to
1
,
regardless of the user-defined configuration.
Usage:
Matchcode is used in applications to sort, route, or verify data based on
matching the specific symbol in a variety of ways as defined in this section.
For example, a manufacturer might sort a product based on dates that
are embedded in the symbol.
