Scanning Tips
Optimal scanning distance varies with bar code density and scanner optics.
•
Hold the scanner farther away for larger symbols.
•
Move the scanner closer for symbols with bars that are close together.
Scan LED Indicator
The LED on the scanner provides a visual indication of the scan status.
Imaging
The wearable terminal with an optional RS507 imager has the following features:
•
Omnidirectional (360°) reading of a variety of bar code symbologies, including the most popular linear, postal,
PDF417, and 2D matrix code types.
•
The ability to capture and download images to a host for a variety of imaging applications.
•
Advanced intuitive laser aiming for easy point-and-shoot operation.
The imager uses digital camera technology to take a digital picture of a bar code, stores the resulting image in its
memory, and executes state-of-the-art software decoding algorithms to extract the data from the image.
Operational Modes
The wearable terminal with optional RS507 imager supports three modes of operation, listed below. Activate each
mode pressing the Scan button.
•
Decode Mode: In this mode, the RS507 attempts to locate and decode enabled bar codes within its field of
view. The imager remains in this mode as long as you hold the scan button, or until it decodes a bar code.
NOTE Scanning procedures depend on the application and wearable terminal configuration. An application may
use different scanning procedures from the one listed above.
