J-3-3 Match Length
Usage: Example:
If
Match Length
is set to
6
in a 10-character symbol, and
Match Start Position
is set to
2
, only the 2nd through 7th characters
(from left to right) will be compared.
Definition:
Defines the length of the character string that will be compared with that
of the master symbol when
Match Start Position
is set to
1
or greater.
When
Match Start Position
is set to
0
, no comparison will occur.

Default: 1
Options:

J-3-4 Wildcard
Usage: Example:
When the
Wildcard
character is defined as the default asterisk,
defining
CR*34
as the master symbol will result in matches for CR
1
34
and CR
2
34, but not CR2345. Entering URGENT** as your master symbol
will result in matches for URGENT, URGENT1, and URGENT12 but not
for URGENT123. This means any wildcards appended to the master
symbol data will result in matches of symbols in variable lengths up to the
master symbol lengths but not over. However, wildcards in the beginning
or center of a symbol (e.g., UR**NT) do not allow for variable symbol lengths.
Definition:
Wildcard Character allows a user to define a wildcard character as part
of the master symbol.

Default: *
(asterisk)
Options:
Any ASCII character.
J-3-5 Sequence on No Read
Usage: Sequence on No Read
is useful when the reader needs to stay in
sequence even if no decode occurs.
Definition:
When
Sequence on No Read
is
Enabled
and
Matchcode
is set to
Sequential
, the reader sequences the master symbol on every match or
No Read. When disabled, it does not sequence on a No Read.

Default: Enabled
Options:
0 = Disabled
1 = Enabled
