Matchcode

Matchcode Type

Definition:

Allows the user to choose the way that master symbols will be compared 

with subsequently read symbols.

Note:

 First set 

Triggering Mode

 to 

External

 or 

Serial

.

ESP:

Serial Cmd:

<

K223,matchcode type

,sequential matching,match start position, 

match length,wild card character,sequence on No Read,sequence on 

mismatch

>

Default:

Disabled

Options:

0 = Disabled

1 = Enabled

2 = Wild Card

3 = Sequential

Disabled:

Has no effect on operations.

Enabled:

Instructs the imager to compare symbols or portions of symbols with the 

master symbol.

Wild Card:

Allows the user to enter user-defined wild card characters in the master 

symbol.

Sequential:

Instructs the imager to sequence after each match (numeric only) and 

compare symbols or portions of symbols for sequential numbers.

Note:

 If 

Matchcode Type

 is set to 

Sequential

, the imager will behave 

as if 

Number of Symbols

 were set to 

1

, regardless of the user-defined 

configuration.
