(2) RTS control
The camera goes into RTS (Random Trigger Shutter) mode when TRIG terminal voltage is
in LOW (Higher than 1V), and starts light-exposure at the rising edge timing.
Under the FIX mode, exposure-time is controlled with inner DIP switch setting.
Under the PULSE mode, the exposure-time is determined by pulse width. Be sure to set the
pulse width longer than 1H (= Approximately 33.2 micro s). The exposure-time control
should be done in CLK steps. After video-output, it goes back into normal operation (=
shutter OFF) if TRIG terminal voltage stays in HIGH for longer than 10V (=
Approximately 1/3s), regardless of the current RTS mode.
Be sure to set the out of use of the two systems of TRIG input to OPEN or HIGH.
If you input correct TRIG signals under GND setting of the out of use terminal,
there are some incapable cases to switch to the RTS mode.
-1 V-reset mode
Exposure starts at the timing of TRIG signal IN. After each exposure is completed, the
camera outputs video immediately by resetting VD. (HD is not reset.)

After TRIG input, BUSY goes into H level immediately
Exposure time varies depending on the mode setting condition such as Pulse mode/Fix mode.
After the exposure, VD is output in
the next HD timing.
At the same time of the end of video output, BUSY goes into L level.
