Operation
Trigger modes
Under the Trigger modes menu item, you can select whether to process one or
several triggers and specify how these triggers should be processed.
Trigger modes: Single trigger
In Single trigger mode, one image is captured and decoded for each external
trigger. Any other triggers that arise during the decoding process are ignored.
Activating the function
Permit asynchronous triggers
permits triggers during
decoding.
■
Suppress unsuccessful read (RS232 & TCP/IP):
Specifies whether the
output of the signal or output string from an unsuccessful read should be
suppressed (activated) or not suppressed (deactivated).
■
Machine cycle:
Machine cycle setting. The value must be greater than
20 ms. The value specifies the time gap between each incoming external
trigger (minimum time). The setting has an effect on the timeout.
■
Permit asynchronous triggers:
Specifies whether or not asynchronous
triggers are permitted. If the field is activated, another trigger can be
processed while a captured image is being processed.
