Overview of Matchcode

Definition:

Matchcode allows the user to store master symbol data in the Imager'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 Imager 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

• Set Triggering Mode to External or Serial.

• Choose the method of symbol comparison that fits your application.

• Define the output you want to achieve with your matchcode setup: Symbol data output; Discrete output

• Select the number of master symbols you want to create.

• Decide which of 4 ways you want to enter your master symbol(s): Use ESP to type master symbol data directly; Send a serial command with symbol data in the form of <M231,master symbol#, data>; Send a <G> (Read Next Symbol as Master Symbol) command; Enable the New Master Pin command and activate the discrete input to store the next symbol read as the master symbol.
