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 Mode command with Motion Detect.
•
The SE4710 optimizes the image output for motion detection.
•
The host sends the Acquisition Start command (and never sends the Stop command).
•
The SE4710 continuously outputs images.
•
In this mode, the SE4710 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 Acquisition Mode command with Barcode Decode.
•
The SE4710 optimizes the image output for bar code decoding.
•
The host attempts to decode the images.
Upon a good decode:
•
The host sends the Aim Off 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 Mode command with Motion Detect.
•
The SE4710 optimizes the image output for motion detection.
During this mode:
•
The SE4710 does not automatically enter standby or low power mode.
•
The host uses the Power Mode command to put the SE4710 into a low power mode (for support of Bus
Powered USB).
