Trigger Types
A DataMan 750 reader supports two trigger types:
• Presentation: Repeatedly scans for a symbol and decodes it
whenever one is detected. The reader relies on an internal timing
mechanism to acquire images.
• Manual (default): Begins acquiring images when you press the
trigger button on the reader, and continues acquiring images until a
symbol is found and decoded or you release the button.
