The ‚Trigger‘ profile menu
This menu is used for setting the trigger source and framegrabbing mode.
Either an external signal applied to the trigger input of the camera (level step 0V
⇒
24V, see chapter
'Technical specifications') or a trigger mechanism built into the camera can be selected as trigger
source for framegrabbing. In the latter case, a free running or register-controlled trigger mechanism
can be chosen from.
Furthermore, the user can select the desired frame rate and the number of images to be captured
(single snapshot, snapshot sequence, continuous "snapshot").
Under 'Trigger Source' the user can choose
one of the following trigger sources:
•
Off
→
Trigger is inactive (live image is
'frozen').
•
External (falling edge)
→
The camera is
triggered by an external signal applied to the
trigger input of the camera. Triggering is
effected by the falling edge of the signal.
•
External (rising edge)
→
The camera is
triggered by an external signal applied to the
trigger input of the camera. Triggering is
effected by the rising edge of the signal.
•
CameraLink CC1
→
The camera is
triggered by an external signal sent from the
CameraLink™ port (CC1, camera control 1).
•
Register
→
The camera is triggered upon
entering the value 1 into the camera register
PARAM_TRIGGER. Alternatively, the 'Trigger
now' button can be used.
•
Auto
→
The camera is continuously
triggered by an internal clock generator.
The 'Trigger Delay' box allows the user to enter
a delay time for the trigger signal.
Under 'Trigger Mode', the user can choose the
framegrabbing
mode
(single
snapshot,
snapshot sequence or continuous mode).
If the sequence mode is selected, the number
of images to be captured can be entered in the
'Trigger sequence count' box.
Under 'Trigger Frequency' the user can specify
a desired trigger frequency in Hz. The
maximum frame rate (in Hz) that can be
reached in dependence of all relevant
parameters is displayed below the box .
It should be noted that the trigger port of the
camera is electrically isolated (see chapter
'Technical
specifications').
The
maximum
trigger frequency is largely dependent on the integration time of the individual image.
