Configuring the Trigger
To configure the camera to work in
trigger mode
, follow the steps below:
1.
Turn off the camera image acquisition.
2.
In the Acquisition Control menu, set
TriggerMode
to
On
.
3.
Set
TriggerOverlap
to either
Readout
for the camera to work in Fast Trigger mode or to
Off
for the camera to work in Standard Trigger mode.
4.
Select
TriggerSource:
•
If
TriggerSource
is either Line1 (Input1) or Line2 (Input2), configure the external trigger
signal source using
LineInverter
feature.
•
If
TriggerSource
is PulseGenerator, configure the camera’s internal pulse generator (see
section Pulse Generator) and make sure that the
PulseGenEnable
setting is checked.
•
If
TriggerSource
is Software, you do not need to configure a signal source.
The camera generates one short trigger pulse when you click the GUI Software Trigger button or
send the GenICam™ Trigger Software command.
5.
For
TriggerActivation
setting,
select what edge (
Rising
or
Falling
) will be used for triggering.
If the
TriggerActivation
is RisingEdge and
ExposureMode
is set to
TriggerWidth, the exposure duration will be the time the trigger
stays high.
If
TriggerActivation
is FallingEdge and the
ExposureMode
is set to
TriggerWidth, the exposure time will last as long as the trigger
stays low.
Set
TriggerActivation
to FallingEdge if the camera works in Fast
trigger mode (
TriggerOverlap
is set to readout) with a trigger
pulse width changing over time (
ExposureMode
is set to
TriggerWidth).
6.
If applicable, set
TriggerFilterTime
,
TriggerDebounceTime
,
TriggerDelay
to desired values.
The
TriggerFilterTime
and
TriggerDebounce
features are used to prevent false triggering
when a trigger signal is being generated by an external source mapped to the camera’s Input
1 or Input 2.
TriggerFilterTime
Defines the input trigger signals minimum pulse width. By setting the
TriggerFilterTime
to a value slightly less than the input signal’s pulse
width, the camera will reject any noise with pulse widths less than the
TriggerFilterTime
setting.
