Aimer Modes
Interlaced In interlaced mode, the illumination and aiming timing is
automatically synchronized to the imager exposure period by the
Image Engine. The engine turns illumination on while the image is
being exposed, and it turns the aiming off at all other times. The
interlaced mode provides the lowest overall current draw and is
recommended for most applications. It also provides the brightest
aimer in most applications. The Image Engine software
automatically maintains an approximate 25% aimer duty cycle,
even when the imager exposure time is at its maximum in dark
operating environments.
Concurrent Concurrent mode is provided for backwards compatibility with the
4X00 Image Engine series, and is not recommended for most
applications. In concurrent mode, the illumination LEDs are on
continuously, while the aimer LEDs turn off during the imager
exposure period, and on while the imager is not exposing.
Concurrent mode is used to eliminate any flicker of the illumination
LEDs that may be objectionable to the user, especially when
running the engine at 12 MHz. The illumination LED current is
reduced compared to interlaced mode to limit engine peak current.
The image engine software automatically maintains an
approximate 25% aimer duty cycle, even when the imager
exposure time is at its maximum in dark operating environments.
Concurrent mode provides the brightest appearance of the
illumination LEDs of any of the imager operating modes. This
mode may be useful for applications when an operator is using the
illumination LEDs for aiming, such as in fixed mount, kiosk, or auto-
trigger applications.
Select Off if you don’t want to use either aimer mode.
