Imager Preferences

The parameters in this chapter control image capture characteristics. Image capture occurs in all modes of
operation, including decode, video, and snapshot.

Operational Modes

The imager has three modes of operation:
•

Decode Mode

•
Snapshot Mode
• Snapshot with Viewfinder Mode
•
Video Mode.
Decode Mode
By default, upon a trigger event, the imager attempts to locate and decode enabled bar codes within its field of
view. The imager remains in this mode as long as the trigger is active or until a bar code is decoded.
Snapshot Mode
Use Snapshot Mode to capture a high-quality image and transmit it to the host. To temporarily enter this mode
capture the Snapshot Mode bar code. While in this mode the imager blinks the green LED at 1-second intervals to
indicate it is not in standard operating (decode) mode.
In Snapshot Mode, the imager turns on the laser aiming pattern to highlight the area to be captured in the image.
The next trigger event instructs the imager to capture a high quality image and transmit it to the host. A short time
may pass (less than 2 seconds) between when the trigger is activated and the image is captured as the imager
adjusts to the lighting conditions. Hold the imager steady until the image is captured, denoted by a single beep.
If a trigger event is not activated within the Snapshot Mode Timeout period, the imager returns to Decode Mode.
