Restriction by polarity setting
7.5.6 Caution when the software trigger is used
The AD-130GE has the following restriction when using the software trigger.
1) The input port of GPIO, Camera 0 and Camera 1 have software trigger 0 to 3, respectively.
However, the output port of GPIO has only one software trigger 0 to 3.
Therefore, the function is described in the figure 21.
It is recommended to use a different software trigger for Camera 0 and Camera 1.

Example of the restriction if the frame start trigger for Camera 0 and Camera 1 is set to TTL In1
[Restriction]
In Sync Mode = Async, TTL In1 I/F is initialized using Trigger Activation of Camera 0 as the reference. If the trigger set in Trigger
Activation is applied to Camera 1 first, Camera 1 cannot recognize the trigger and misses one frame. (Case
