6.6.6.
Auto Reset mode
In this mode, when the interval of the trigger pulse is more than 55ms, the CV-L108CL automatically
returns to continuous operation with the line rate of 14.10μs . At this time, DVAL and Video OUTPUT
are disabled 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 than 55ms, CV-L108CL
operates in the original trigger mode selected.
Note: CV-L108CL functions properly according the selected operation mode while the Auto
Reset 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-L108CL 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.
