5.4 Trigger and Strobe
5.4.1 Trigger Source
The trigger signal can be configured to be active high or active low by the
TriggerActivation
(category
AcquisitionControl
) property. One of the following trigger sources can be used:
Free running The trigger is generated internally by the camera. Exposure starts immediately
after the camera is ready and the maximal possible frame rate is attained, if
AcquisitionFrameRateEnable is disabled. Settings for free running trigger mode:
TriggerMode = Off. In Constant Frame Rate mode ( AcquisitionFrameRateEnable = True),
exposure starts after a user-specified time has elapsed from the previous exposure start so
that the resulting frame rate is equal to the value of
AcquisitionFrameRate .
Software Trigger The trigger signal is applied through a software command ( TriggerSoftware
in category AcquisitionControl ). Settings for Software Trigger mode: TriggerMode = On
and
TriggerSource
= Software.
Line1 Trigger
The trigger signal is applied directly to the camera by the power supply
connector through pin ISO_IN1 (see also Section A.1). A setup of this mode is shown in
Fig. 5.19 and Fig. 5.20. The electrical interface of the trigger input and the strobe output
is described in Section 7.6. Settings for Line1 Trigger mode:
TriggerMode = On and
TriggerSource = Line1.
PLC_Q4 Trigger The trigger signal is applied by the Q4 output of the PLC (see also Section 7.7).
Settings for PLC_Q4 Trigger mode: TriggerMode = On and TriggerSource = PLC_Q4.
ABTrigger Trigger from incremental encoder (see Section 5.4.9).
Some trigger signals are inverted. A schematic drawing is shown in Fig. 8.4.
