SE3300 Integration Guide
Recommended Procedures
The following trigger mode procedures describe the recommended transaction sequence between a host and
the SE3300. These transaction sequences use discrete commands for clarity. Replace any set of discrete
commands with a multi-command EXECUTE_SCRIPT to improve throughput.
Normal Decode Mode
Level Trigger Mode Procedure
The system is initialized as follows:
•
The host sends the Aim Off command.
•
The host sends the Illumination Off command.
•
The host sends the Acquisition Stop command.
•
The host sends the Barcode Decode mode command.
•
The SE3300 optimizes the image output for bar code decoding.
•
The SE3300 enters standby mode (or low power mode if enabled).
Upon a trigger pull:
•
The host sends the Illumination On command.
•
The SE3300 exits standby mode (or low power mode if enabled).
•
The host sends the Aim On command.
•
The host sends the Acquisition Start command.
•
The SE3300 begins outputting images.
•
The host attempts to decode the images.
Upon a good decode or trigger release:
•
The host sends the Acquisition Stop command.
•
The SE3300 stops outputting images.
•
The host sends the Aim Off command.
•
The host sends the Illumination Off command.
•
The SE3300 enters standby mode (or low power mode if enabled).
