Decoding
The terminal supports two types of image decoding for use in various bar code reading and imaging
applications: full-area imaging and Advanced Linear Decoding (ALD).
Full-Area Imaging
Full-area imaging provides omni-directional reading of linear and non-linear 1D and 2D bar codes, OCR,
signature capture, and picture taking. When reading all bar code types using full-area imaging, a positive
read can be obtained from many positions; see
Aiming Options on page 4-4. To achieve the best read,
the aiming beam should be centered horizontally across the bar code.
ALD
ALD provides fast reading of linear and stacked linear bar codes. To achieve a positive read when read-
ing linear 1D and PDF417 bar codes, the green aiming beam should be centered horizontally across the
bar code. When ALD is enabled, the reader does not read matrix or postal codes.
To Decode a Bar Code
The aiming beam should be oriented in line with the bar code to achieve optimal decoding. A range
of 4-10 inches (10-25 cm) from the bar code is recommended.
1. Tap > Demos > Scan Demo .
2. Point the Dolphin terminal at the bar code.
3. Project the aiming beam or pattern by pressing and holding the SCAN key .
4. The scan LED lights red.
5. Center the aiming beam over the bar code; see Aiming Options on page 4-4.
6. When the bar code is successfully decoded, the decode LED lights green and the terminal beeps.
7. The bar code information is entered into the application in use.
Aiming Options
The aiming beams are smaller when the terminal is held closer to the code and larger when it is farther
from the code. Symbologies with smaller bars or elements (mil size) should be read closer to the unit
whereas symbologies with larger bars or elements (mil size) should be read farther from the unit.
