Stop Recording using the Trigger
The camera also stops recording when it receives a signal through the Trigger input. Recording
stops at the frame determined by the Trigger Point setting, see Figure1-8. The trigger can be set
from 0% to 100% in 10% increments to adjust the
length of time the images show before and after the
event that caused the trigger. The percent value
represents the proportion of the sequence shown
before the event.
For example, if the trigger is set to 50% as
illustrated, the camera continues to record over the
second half of the image memory and then stops.
Half of the sequence shows frames that precede
the trigger and half shows events after the trigger.
If the Trigger Point is set to 20%, then 20% of the
images precede the trigger, and 80% follow the
trigger.
Figure 1-8 The 50% Trigger.
The active frame when the trigger is received is Frame 0
for that sequence. If the Trigger point were set to 0%, all
images in the memory would show events after the trigger
occurred. If the Trigger Point were set to 100% all images
would precede the trigger, the equivalent of using the
manual stop. A message shows on the screen between
the time of receipt of the trigger signal and the time the
camera stops recording to confirm that the trigger was
received and to prevent the operator from pressing Stop
manually.
Figure 1-9 The 0% Trigger.

Playing Images from the Image Memory
You can play back the images from memory as soon as the sequence is recorded. The camera
plays the images in Step mode, or at playback rates from 1 fps to 1000 fps. The images can be
saved in a computer file and replayed at any time.
1.6.4
Frame Numbers and Elapsed Time Display
During playback from the image memory or from a computer file, the menu shows the frame
number and time of the frame currently displayed. These numbers are referenced from the
Frame 0 assigned to that sequence. Frames following Frame 0 trigger are assigned positive
frame numbers from Frame 1 to the last frame stored. Frames preceding the trigger are given
negative frame numbers from Frame –1 to the first frame stored. The viewfinder and monitor
shows the time of each frame to 0.0001 seconds with reference to Frame 0.
1.6.5
Saving a Sequence in a Computer File.
Images recorded in the image memory will be lost if another recording is made. Therefore any
video data required later must be stored externally before making another recorded sequence.
Connect the Video Out output to a VCR or a computer with a video processor board.
