The conditions for this table are that shutter speed should be set the same for all sequences. If

the shutter speed is different, the difference of exposure time should be added.
recommended to set the exposure time in order of the shortest to the longest one.
Do not input the trigger just after the sequence is reset. It requires at least 500ms delay.

In sequential mode, the exposure should be adjusted so that the LVAL a-sync mode can always

be functioned.

8.5.5 Delayed Readout mode (Pre-Select trigger and pulse width control trigger)

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 trigger 0 and it is stored in the memory located
at Ethernet Interface. By the falling edge of the trigger 1, the image data is output.
