Last Frame and New Trigger

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 External Edge, Serial Data, or Serial Data and 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 and 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

labelled object could appear before the last frame in a Rapid Capture

sequence.

Definition: Last Frame and New Trigger 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.

Serial Cmd: <K220,end of read cycle,read cycle timeout>

Default: 250 (x10 ms or 2.5 seconds)

Options: 1 to 65535
