J-3 Matchcode
Note: Match Start Position
must be set to
1
or greater to enable this feature.
0
disables this feature.
Definition:
Allows you to choose the way that master symbols will be compared with
subsequently read symbols.
Note:
First set
Triggering Mode
to
External
or
Serial
.
Serial Cmd:

>
Default: Disabled
Options: 0 = Disabled
1 = Enabled
2 = Wildcard
3 = Sequential
Disabled:
Has no effect on operations.
Enabled:
Instructs the reader to compare symbols or portions of symbols with the
master symbol.
Wildcard:
Allows the user to enter user-defined wildcard characters in the master
symbol.
Sequential:
Instructs the reader 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 reader will behave
as if
Number of Symbols
were set to
1
, regardless of the user-defined
configuration.
J-3-1 Sequential Matching
Usage:
Useful in tracking product serial numbers that increment or decrement
sequentially.
Definition:
With Sequential enabled,
Sequential Matching
determines if a count is
in ascending (incremental) or descending (decremental) order.
Serial Cmd:
<
K223, matchcode, sequential matching ,match start position,match
length,wildcard,sequence on No Read,sequence on mismatch,placeholder
character
>
Default: Increment
Options: 0 = Increment
1 = Decrement
J-3-2 Match Start Position
Usage: Match Start Position
is useful in defining specific portions of a symbol
for comparison. For example, if a symbol contains a part number, manufacturing
date, and lot code info, but you are only interested in the part number
information, you can set the reader to sort only the part number and
ignore the other characters.
Definition: Match Start Position
determines the portions of symbols that will be
matched by defining the first character in the symbol (from left to right)
that will be compared with those of the master symbol, when
Matchcode
Type
is set to
Enabled
or
Sequential
.
Function:
For example, if
Match Start Position
is set to
3
, the first 2 characters
read in the symbol will be ignored and only the 3rd and subsequent
characters to the right will be compared, up to the number of characters
specified by
Match Length
.
