Read Cycle
Continuous Read 1 Output
Caution: In automated environments, Continuous Read 1 Output is not recommended
because there is typically no reliable way to verify that a symbol was missed.
Note: 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.
Usage:
Continuous Read 1 Output can be useful in applications where it is not
feasible to use a trigger and all succeeding symbols contain different
information. It is also effective in applications where the objects are presented
by hand.
Definition:
In Continuous Read 1 Output the imager self-triggers whenever it
decodes a new symbol or a timeout occurs.
If End of Read Cycle is set to Timeout and the symbol doesn’t change,
the output is repeated at the end of each timeout period. For example, if
Timeout is set to one second, the imager sends the symbol data immediately
and repeats the output at intervals of one second for as long as it continues
to capture the symbol.
If End of Read Cycle is set to New Trigger, the imager will send the current
symbol data immediately,
but only once
. A new symbol appearing in the
imager’s range will be read and sent immediately, provided it is not identical
to the previous symbol.
