I/O controlled sequence pointer reset

I/O controlled sequence pointer reset is always edge controlled. A rising

edge on the input pin resets the pointer to the first entry.

I/O controlled sequence pointer reset can be combined with Quick Format

Change Modes. See Chapter Standard Parameter Update Timing on page 134

and Chapter New: Quick Format Change Mode (QFCM) on page 134.

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.
