Example 3. How 4 memories can store image again
(1) Apply " [Frame Start Trigger]-[Trigger Source] Trigger signal" four times.
(2) Apply "[Acqusition Transfer Start]-[Trigger Source] signal once. By doing this input, the first stored image can be readout. And the memory which stores the first image becomes
available to store a new image.
(3) Apply "[Frame Start Trigger]-[Trigger Source] Trigger signal" once (This is fifth trigger signal). Then the image can be stored in memory.
(4) Apply "[Acqusition Transfer Start]-[Trigger Source] signal" twice. Those two signals clear the next two memories.
