Trigger Modes

END

The Processor treats memory as a circular buffer when using the END mode.
Pictures are stored in sequence with the current picture replacing the oldest
picture in memory until you press the TRIGGER button again or a trigger signal
is received through TRIGGER IN or TRIGGER SW IN on the rear panel of the
Processor. This approach to recording gives you an infinite amount of record
time while you wait for something to happen. After the recording is stopped you
will have the last 546 frames of action stored in memory.
The END mode is used when the experiment has an observable end and you are
interested in the action immediately before the recording was stopped.
