(4) RTS (Random Trigger Shutter) Pulse Control
The camera goes into RTS (Random Trigger Shutter) mode when TRIG terminal voltage is in
HIGH (More than 1V), and starts light-exposure at the falling edge timing. Under FIX mode, the
exposure-time is controlled with inner DIP switch settings. Under PULSE mode, the exposure-time
is determined by pulse length. The exposure-time control is done in 1H steps. Be sure to set the
pulse length longer than 1H (=Approximately 62.5 micro s). After video-output, it goes back into
normal operation (= inner DIP switches) if the TRIG terminal voltage stays in LOW.
The exposure starts at the next HD timing immediately after TRIG IN.
