Overview of Matchcode

Overview of Matchcode

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.
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.
