To synchronize the flash with the input of an external trigger, use the [REMOTE] connector on
the rear.
Pin configurations of connectors (page E12).
When the shutter mode is other than
RANDOM EEI (
page E34, SHUTTER item)
In response to the trigger input, the KY-F1030 outputs a flash signal for the CCD accumulation
period of the next frame.
The image shot at the moment that the FLASH signal is outputted is output as the next frame.
In the case of digital output, output stops with shooting of this frame and the image on the
PCs monitor will be in the FREEZE condition.
How to cancel the FREEZE condition can be selected. ( page E40, [FRZ CANCEL] item)
The trigger interval must be minimum 3 frames (405 msec) at a shutter speed of 1/7.5 s or
faster.
When the FREEZE cancel mode is set to
MANUAL, FLASH will not be output in response to
the trigger input for FREEZE cancellation.

MEMO
During output of the FLASH signal, the [FREEZE] indication will appear momentarily on the com-
puter monitor. If it is preferred that the indication is not shown, set the [FRZ DISPLAY] item to OFF.

When the shutter mode is RANDOM
CCD accumulation is performed in sync with the trigger input, and this period is output as the
FLASH signal.
At the same shutter speeds the delay from the trigger input to the FLASH output is almost
uniform as shown in Table A below. Also, the pulse width of the FLASH output differs with the
shutter speed.
The trigger input interval is restricted as shown in Table B. Do not input at a shorter
interval than the minimum interval shown in the table.
MEMO
In the condition where the shutter mode is RANDOM, the image quality may deteriorate at the time of
FREEZE as noise may be applied or white spots may appear.
