1 - 2 SE3300 Integration Guide
SE3300
The SE3300 contains:
•
a monochrome CMOS image sensor
•
an LED based aiming system
•
an illumination system
•
a standardized camera interface port and bi-directional control interface (I

SE3300 Block Diagram
A 21-pin ZIF connector on the SE3300 connects the engine and the host device via a 55 mm flex (available
from Motorola). For information about this connector, see
Figure 4-3 on page 4-4 and Figure 4-5 on page 4-6 .
An amber LED and associated optics generate an aiming pattern, and dual, high output LEDs provide
illumination for the imager under virtually any lighting condition. The aiming subsystem, illumination system,
and frame rate are under dynamic software control.
The primary component of the SE3300 imager is a 1/3" format CMOS wide VGA (752 H x 480 V) monochrome
digital image sensor. The CMOS sensor converts photons to a digital representation (8 bits per pixel) of the
image present on the sensor.
