V440-F C-Mount Code Reader User Manual
This feature allows you to set the timing of external illumination hardware
to coordinate it with the V440-F image sensor.

Fixed Light On Time is the amount of delay after the external lighting is
turned on before the reader captures an image. This allows the external
lighting time to reach full power.

Fixed Light On Delay Time is the amount of time the external light should
be on after the sensor starts an image capture. If set to a value other than
0, this time interval should be shorter than the sensor's exposure/integration
period. The light is always forced off after the sensor's exposure/integration
time is up. Fixed Light On Delay Time allows you to configure a light pulse
that is shorter than the sensor's integration time.
The V440-F's image sensor is very fast (the V440-F sensor supports 16 μs
shutter exposure times), and this delay accounts for any potential lag time
in external lighting hardware. It allows slower lights to reach full illumination
in a shorter time than the sensor's exposure/integration period.
