“
Ignore
” – the next rigger will be ignored, and the camera will continue its
present operation.
-
“
Accept
” – the next trigger will be used. The camera will stop the present
operation, will reset and the new trigger cycle will start.
-
“
Accept after Exposure
” – the next rigger will be ignored while the camera
is exposing the image. The next trigger will be used only after the image
exposure based on the previous trigger has been completed. The camera will
stop the present operation, will reset and the new trigger cycle will start.
4.
“
Exposure Time
” – the exposure for all frames can be set in two ways:
-
“
Pulse Width
” – the trigger pulse width (duration) determines the exposure.
-
“
Internal
” – the camera internal exposure register determines the exposure.
A mid exposure pulse is generated in this mode.
5.
“Frames captured
” – the number of frames captured after the trigger pulse can
be programmed from 1 to 65530 frames, or to be free-running.
6.
“Exposure Delay”
– delays the beginning of the exposure with respect to the
trigger pulse. The delay can be programmed from 0 to ~16,777 seconds.
CAUTION NOTE
1.
The de-bounce interval MUST be smaller than the trigger pulse duration. Adjust
the interval accordingly.
2.
When Triggering is enabled “Programmable Integration” is not active
2.6.3 Trigger Strobe Control
Along with the shutter pulse, the camera can send one strobe pulse for
synchronization with an external light source. The user can set the strobe pulse
duration and the delay with respect to the trigger pulse active edge. The maximum
pulse duration and the maximum delay can be set up to 16777215 us with 1.0us
precision. The strobe pulse can be assigned to “Strobe 1” or “Strobe 2. If the number
of frames captured is more than 1, and the user wants to enable the strobe for the
next frames, he/she has to using the camera strobe – please refer to “Strobe” section
for more information.
2.6.4 Triggering modes
A.
Standard Mode
When the standard triggering mode is enabled, the camera idles and waits for a
trigger signal. Upon receiving the external trigger signal, the camera clears the
horizontal and vertical registers, sends a shutter pulse to clear the pixels and starts
