6.6.6.
Auto Reset mode
In this mode, when the interval of the trigger pulse is more than 55ms, the CV-L107CL automatically
returns to continuous operation with the line rate of 52.5μs . At this time, DVAL,EEN and Video
OUTPUT are disable in order to prohibit charge due to dark current to add up in the sensor in
standby periods.
While the Auto Reset mode is “ON”, if the trigger interval becomes less 55ms, CV-L107CL operates
in the ordinal trigger mode selected.
In the Shutter-select mode, the exposure restarts at the first trigger pulse and, after exposure, the
video signal is output.
In the No-shutter mode, the exposure restarts at the first trigger pulse but the video signal is output
after the second trigger pulse is input.
Note: CV-L107CL functions properly according the selected operation mode while the Auto Rest
mode is “ON”. However, if the system uses LVAL, it is recommended to set the Auto Reset at
“OFF” as LVAL is always output.
For this mode, CV-L107CL provides Auto Reset mode command “ARST”.
In the default setting, “ARST” is set at “ 0 “ (OFF). In order to activate this mode, “ARST” should
be set at “1”.
The following is the concept of the Auto Reset Mode.
