Overview of Matchcode
Steps for Entering and Using Master Symbols
1. Set Triggering Mode to External or Serial .
2. Choose the method of symbol comparison that fits your application.
3. Define the output you want to achieve with your matchcode setup:
a. Symbol data output
b. Discrete output
4. Select the number of master symbols you want to create.
5. Decide which of 4 ways you want to enter your master symbol(s):
a. Use ESP to type master symbol data directly.
b. Send a serial command with symbol data in the form of <M231, master symbol#,
data > .
c. Send a <G> ( Read Next Symbol as Master Symbol ) command.
d. 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 Number of Symbols 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.
