Exposure time delay under RTS

When the RTS is active, both in FIX mode and PULSE W mode, there is a time delay of
approximately 1.4 micro s until the start of exposure after the rising edge of TRIG signal
(positive).

Exposure time under pulse width mode

Under RTS pulse mode, the exposure time is determined by the pulse width. More exactly,
the actual time is the pulse width plus approximately 8.0 micro s.



(4-3) Restart / Reset

The restart / reset function is available with the ext.VD signal. You can get an arbitrary
slower shutter speed than normal shutter and random trigger shutter.

Here are some notes;
*

The shutter speed (exposure time) is determined by ext. VD signal interval.

**

This function is enabled when the rear-panel shutter speed DIP SW is OFF.

*** Supply consecutive HD.
