4. Reset control (External trigger operating mode: Mode 14)
When the external trigger signal is HIGH ACTIVE, exposure begins at the rising edge of the trigger signal and ends at the
falling edge. At the Readout pulse falling edge, the internal VD signal is reset and the video data are transmitted.
Note: Special function of rest control trigger
The camera shifts to the output of a normal mode (continuous output) when Trigger B signal passes about 1/3
seconds in the state of High. (The image is output by inputting the Trigger at the VD cycle for this period.)
It returns to the Reset control mode if Trigger B signal becomes Low. However, after becoming Low Trigger B, the
period of 50 ms becomes a Trigger A signal input prohibition period.
