line rate of the camera based on the Automatic Line Rate Reference Level (as set in
command AL) and the scene illumination. Please note that the aspect ratio of the scanned
object will change as the line rate is changed.

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-050CL
automatically returns to the internal trigger mode with the line rate of approx. 14.1μsec.
In this time, the camera operates by the internal trigger, and if the external 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 ARST 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 and only LVAL is output
.
