QX Hawk Industrial Imager User Manual 5-167
Parameters
Overview of Matchcode
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 Trigger 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.
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 Trigger Mode to External Level, External Edge, or Serial Data.
2. Choose the method of symbol comparison that fits the application.
3. Define the type of output required with Matchcode setup:
a. Symbol data output
b. Discrete output
4. Select the number of master symbols required.
5. Decide how the master symbol(s) will be entered:
a. Use ESP to type master symbol data directly.
b. Send a serial command with symbol data in the form of
<K231,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.
