．
In the Sequential EPS Trigger, LVAL sync operation is not available as the different
exposure time and gain in each sequence table can be set. The trigger should be applied in
LVAL Async timing.

In order to change values in the Sequence Table, image capture must be stopped.
10.6.9 Delayed Readout EPS and PWC Modes
This mode can be used to delay the transmission of a captured image. When several cameras
are triggered simultaneously and connected to the same GigE interface, it allows the cameras
to be read out in sequence, preventing congestion.
The image data is not transmitted directly by the Frame Start Trigger and is stored in the
memory located at the Ethernet Interface. By the leading edge of the Transfer Start Trigger,
the image data is output.
AD-131GE has up to 6 memories to store, and the stored image data can be output at the
consecutive timing of Transfer Start Trigger.
After the stored image is transmitted by Transfer Start Trigger,
as the memory has the space,
it is possible to store new images by Frame Start Trigger.
This mode can work in EPS mode and PWC mode. This is not available for Sequence Trigger.

10.6.10 Multi ROI mode (Multi Region of Interest)
In this trigger mode, up to 5 ROIs located on one image can
be output by one trigger input. By using this mode, the
data stream can be smaller.
Each ROI can be overlapped.
Please note that if the accumulated data size is bigger than
the data size of 1 frame, the frame rate will be reduced.
Also accumulated heights for each ROI should be within 966
lines.
