Matchcode

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 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

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.
