Decoding

The Dolphin terminal supports two types of image decoding: full-area imaging and Advanced Linear Decoding (ALD).

Full-area Imaging

Full-area imaging means that the Dolphin terminal support omni-directional aiming, which means that a positive read can be obtained from many positions. For details, see OmniDirectional Scanning Positions on page 5-4.

ALD

ALD provides fast reading of linear (1D) and stacked linear bar codes (e.g., PDF417). For the best read, the aiming pattern 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 Code1.Tap Start > Demos > Scan Demo.

2.Position the Dolphin terminal over one of the sample bar codes on page 5-5. A range of 4–10 inches (10–25 cm) from the bar code is recommended.

3.Project the aiming pattern by pressing and holding the Scan trigger. The Scan LED lights red.

4.Center the aiming beam over the bar code. The aiming beam should be oriented in line with the bar code to achieve optimal decoding; see Omni-Directional Scanning on page 5-6.

5.Release the Scan trigger.

6.When the bar code is successfully decoded, the decode LED lights green and the terminal beeps.
