The data can be stored in the camera memory for next start up.
7.4 Command ARST – Auto Reset Mode
This function enables/disables the Auto Reset mode, which prevents offset rising in special
case where line triggers are not received for long periods of time.
Settings 0 (off) and 1 (on). Factory default is 0 (off).
In this mode, when a trigger pulse does not occur after more than 53ms, the LQ-200CL
automatically returns to continuous operation with the line rate of 52.5μs. In this time,
the camera operates by the internal trigger, and if the trigger is input, the video is
immediately output. In the Shutter-Select mode, the exposure starts immediately after
the trigger is input and the camera outputs the video. In the No-Shutter mode, the exposure
will start immediately after the trigger is input, but the video output is available after the
second trigger pulse is input. In this mode, DVAL, EEN and Video OUTPUT are disabled in
order to prevent charges due to dark current from building up in the sensor during standby
periods.
Note: LQ-200CL 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 to “OFF” as LVAL is always output.
