Publication 2755-833
None The factory default setting for each output is None,
which means an output condition is not defined.
You can hold an output open or closed by setting the
condition to None and then changing the Output
State to normally open or normally closed.
Match-Entry Activates the specified output when bar code data
matches the string to the left of the output. Used for
verification of specific label information.
The corresponding output counter increments each
time a match entry occurs.
In the following example, Output 1 (normally open
contact) will activate (close) for 100 milliseconds if
decoded data matches 123456.
Match-Complete Activates the specified output when bar code data
from a valid package matches the number of entries
in the primary match code table as set by the Match
Complete parameter.
The match-complete condition is used to verify that
multiple symbols with different information appear
on the same package.
Read (Package) Activates the specified output when bar code data
results in a valid package.
The read (package) condition is used to verify the
presence of a good label.
The corresponding output counter increments once
for each package read.
No-Read (Package) Activates the specified output when a no-read
occurs for the last processed package.
The no-read condition is used to detect missing or
damaged labels.
A no-read occurs when end of trigger occurs without
a valid package
The corresponding output counter increments once
for each package not read.
NOTE: The no-read condition does not exist in
continuous mode.
