Read Cycle Timeout
Usage: New Trigger is an effective way to end a read cycle when objects move
past the reader at irregular intervals (not timing dependent).
Definition: New Trigger ends the current read cycle and initiates a new one when a
new trigger occurs. New Trigger refers only to a “rising edge” trigger.
With either External Edge , Serial, or Serial or Edge enabled, an edge or
serial trigger ends a read cycle and initiates the next read cycle.
In the case of External Level , a falling edge trigger ends the read cycle but
the next read cycle does not begin until the occurrence of the next rising
edge trigger.
Usage: Useful in applications that require an alternative way to end the read cycle.
For example, if an assembly line should stop completely or the intervals
between objects are highly irregular.
Definition: Timeout or New Trigger is identical to Timeout except that a timeout or a
new trigger (whichever occurs first) ends the read cycle.
Usage: Useful in applications in which the number of captures needed can be
defined but the timeout duration varies.
Definition: Last Frame only applies to Rapid Capture mode.
Usage: Useful in applications in which line speeds are irregular and a new labeled
object could appear before the last frame in a
Rapid Capture sequence.
Definition: New Trigger or Last Frame is identical to New Trigger except that a new
trigger or last frame (whichever occurs first) ends the read cycle.
Definition: Read Cycle Timeout is the duration of the read cycle.
