Product Reference Guide 1Chapter 1IntroductionAbout the ScannerBridging the gap between man and machine, the Heron™ HD3130 linear imagerbrings high style along with technology to the modern point of sale. Distinctivefeatures such as side and top lights, polyphonic speaker and stylish top covers,as well as Green Spot technology, characterize this innovative reader.Perfect for use as both a handheld and a presentation style reader, the Heronimager is lightweight and ergonomically shaped for handheld use and includesan auto-sensing stand in the package.Developed to satisfy the most demanding reading requirements for linear read-ing at POS checkout, the Heron linear imager is available as an all-in-onemulti-interface solution (RS-232, USB and Wedge).The Heron™ HD3130 Linear Imager has several new features. See "ReadingParameters" on page 61 for information on setting these features:• The reader's attractive illumination (top and sides) selectively changescolor to indicate its status.• The user has the option to use personal jingles (a short user-defined tuneuploaded via Datalogic Aladdin™ configuration software) instead of thenormal beep tone.Using the Heron ReaderHeron readers automatically scan barcodes at a distance. Simply aim and pullthe trigger. Code scanning is performed along the center of the light bar emit-ted from the reading window. This bar must cover the entire code.Effective scanning is obtained by tilting the scanner with respect to the barcodeto avoid direct reflections, which impair the reading performance (see Figure 1Abelow). A successful read is signaled by an audible tone or a jingle (previouslyuploaded), plus a good-read green spot. The side and upper illuminatorsbecome green (unless another color has been configured with Datalogic Alad-din™ configurator).Once the reader is correctly inserted into the stand, it is immediately ready toautomatically read any code present in its reading area without pressing thetrigger. Furthermore, a green aiming light (Datalogic’s patented ‘Green Spot’) iscontinuously emitted to facilitate the positioning of the bar code to be read(shown in Figure 1B).To guarantee single code reading, consecutive reading of the same coderequires the code to be removed from the reading area (no decoding) beforethe reader will accept the same code again.
