Presentation Mode Procedure
The system is initialized as follows:
•
The host sends the Aim Off command.
•
The host sends the Illumination On command.
•
The host sends the Illumination Power Off command (Off is the default, but power can be set low to allow
motion detection in darkness).
•
The host sends the Acquisition Start command (and never sends the Stop command).
•
The host sends the Motion Detect mode command.
•
The SE3300 optimizes the image output for motion detection.
•
The SE3300 continuously outputs images.
•
In this mode, the SE3300 does not enter standby or low power mode.
Upon the host detecting motion:
•
The host sends the Aim On command.
•
The host sends the Illumination Power Full command.
•
The host sends the Barcode Decode mode command.

The SE3300 optimizes the image output for bar code decoding.
•
The host attempts to decode the images.
Upon a good decode:

•
The host sends the Illumination Power Off command (Off is the default, but power can be set low to allow
motion detection in darkness).
