Operation: IDS NXT
In this trigger mode, the live image only shows an image if a trigger has been activated. In the live image, you
can see the capture date of the last image in the lower right corner.

With the
button, you can activate a software trigger manually in IDS NXT Cockpit.
6.1.3.3 Trigger type "Hardware"
In the "Hardware" mode, image acquisition is activated via an external trigger signal.
Exam ple: Trigger type "Hardw are" w ith rising edge
In this mode, you have the following additional settings:
·
Edge
Falling: image acquisition starts when the trigger input signal has a falling edge.
Rising: image acquisition starts when the trigger input signal has a rising edge.
Both: both rising and falling edges trigger image acquisition.
·
Delay: With this option you can set the delay between the input of a trigger signal and the start of image
acquisition.
·
Debounce: This function can be used to suppress interference at the trigger input. A signal at the trigger
input is only recognized as a trigger if the signal level remains constant during the set time.
·
Timeout: set inactive time (pause) after the last trigger detection before the trigger detection starts again.
·
Prescaler: Via the trigger prescaler (frequency divider) you can set that the incoming trigger signals are pre-
divided by the set value. This is the case if the external trigger source provides more trigger pulses than
needed for capturing. The set value, e. g. 4, defines that only every 4th trigger signal is used to start image
acquisition.
