Minumum Duration
(in μs)
CORACQ_PRM_EXT_TRIGGER_DURATION
Minimum external trigger pulse duration (in µs), needed
for the pulse to be acknowledged by the acquisition
device. If the duration of the pulse is shorter, the pulse is
ignored.
This feature is useful for trigger pulse debouncing. If the
value is ‘0’, no validation is performed
Frame Count per
External Trigger
CORACQ_PRM_EXT_TRIGGER_FRAME_COUNT
Number of images to acquire upon receiving an external
trigger. Valid range is 1-262142.
Note, infinite frame count (-1) is not supported.
External Trigger
Delay
Sets the delay between the reception of the trigger signal
and the start of the image acquisition. Units are specified
by the External Trigger Delay Time Base parameter.

Delay Time Base
CORACQ_PRM_EXT_TRIGGER_DELAY_TIME_BASE
Sets the external trigger delay time base.
Possible values:
•
Line Counts
•
Nanoseconds
•
External Line Trigger or Shaft Encoder

Ignore Delay
CORACQ_PRM_EXT_TRIGGER_IGNORE_DELAY
Sets the time delay, in µsec, where if another external
trigger occurs, it is ignored. Valid range is 0-42949672.
The start of the delay (time '0') is the end of the next
vertical sync for analog cameras, or the beginning of the
next frame valid for digital cameras, following a valid
external trigger.
