Aimer Modes
This feature allows you to select from the three options listed below:

Aimer Mode Off

Aimer Mode is disabled.

Interlaced Mode

In Interlaced Mode, the illumination and aiming timing is automatically
synchronized to the imager exposure period by the Optics Module. The
module turns illumination on while the image is being exposed, and it
turns the aiming off at all other times. Interlaced Mode provides the low-
est overall current draw and is recommended for most applications. It
also provides the brightest aimer in most applications. Imager 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

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. This Mode is used to eliminate any
flicker of the illumination LEDs that may be objectionable to the user.
In Concurrent Mode, the illumination LED current is reduced in com-
parison to Interlaced Mode with regard to limiting engine peak current.
Imager software automatically maintains an approximate 25% aimer
NOTE
When in Interlaced Mode, the illumination level
will dynamically change with the degree of
ambient light and reflection from the bar code
being scanned.
NOTE
Concurrent Mode is provided for backwards
compatibility with previous models, and is not
recommended for most applications.
