One Shot CMD and actual operation timing
As shown in the following figure, it takes at least about 1 V for the actual isochronous transmission to start after the One Shot
command (CSR F0F0061Ch) has been set to the CSR of the camera.
(VDs are the reference signals inside the camera and cannot be observed from outside the camera.)
If Shutter is set to the extended exposing mode, isochronous transmission start may delay for the exposure time at maximum
in addition to the previous delay.
Do not set a new One Shot command until isochronous transmission completes after the One Shot command has been set to
the CSR.
Trigger Mode command and actual operation timing
As shown in the following figure, it takes about 430 ms (DFW-SX900), 360 ms (DFW-X700) at the least for external trigger
signals to be received (Trigger Mode) after the Trigger ON command has been set to the CSR (F0F00830h) of the camera.
