SE4400 Integration Guide
Aiming Control
The aiming subsystem is under dynamic software control and is independent of the
illumination subsystem.
The SE4400 can capture images with both the aiming subsystem turned on (the image of
the aiming pattern is captured in the digital image) and the aiming subsystem turned off.
Illumination System
An illumination subsystem, consisting of one red 635 nm LED, is provided to meet the
image capture and decoding requirements throughout the full range of ambient lighting
(total darkness to full sunlight).
Illumination Control
The SE4400 can capture images with the illumination subsystem turned on or off,
accommodating images that are close to the wavelength of the illumination. For example,
since red LED illumination is used, it may be desirable to shut off the illumination when
capturing a printed image in red ink.
Focus Control
The SE4400 has two focus positions controlled by an electromagnetic motor, which is
under dynamic software control and is independent of the illumination and aiming systems.
The operating modes of the motor are:
•
Disabled (off)
•
Near Focus
•
Far Focus
•
Toggle (automatic switching between near and far focus positions).
