I/O controlled sequence stepping mode and I/O controlled
sequence pointer reset via software command

Both sequence modes can be controlled via software command.

Points to pay attention to when working with a
sequence

The following screenshot shows an example of a sequence for eight different
image settings. It uses the AVT Firetool program as graphical representa-
tion. Please note the changes in the shutter time; that creates descending
image brightness, and the change in the image position; which creates a
panning effect.

Note

If more images are recorded than defined in
SeqLength, the settings for the last image remain in
effect.

If sequence mode is cancelled, the camera can use the
FIFO for other tasks. For this reason, a sequence must
be loaded back into the camera after sequence mode
has been cancelled.

To repeat the sequence, stop the camera and send the
multi-shot or IsoEnable command again. Each of these
two commands resets the sequence.

Using single-shot mode in combination with a
sequence does not make sense, because single-shot
mode restarts the sequence every time.

The sequence may not be active when setting the
AutoRewind flag. For this reason it is important to set
the flag before the multi-shot or IsoEnable commands.

If the sequence is used with the deferred transport
feature, the number of images entered in Seq_Length
may not be exceeded.
