COMMAND SETTING AND OPERATION TIMING

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.)

Set One Shot in this period

Approx. 8.0 ms (DFW-SX900) Approx. 2.4 ms (DFW-X700)

Isochronous

ON

One Shot is executed with an interval of 1 V from V period set

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.
