Heron™ HD3430
Using the Heron™ Series Readers
The Heron HD3430 Linear Imager has several new features:
• the reader's attractive illumination (top and sides) selectively
changes color to indicate its status.
• the option to use personal jingles (a short user-defined tune
uploaded via Datalogic Aladdin™ configuration software) instead
of the normal beep tone.
Heron readers automatically scan bar codes at a distance. Simply
aim and pull the trigger. Code scanning is performed along the cen-
ter of the light bar emitted from the reading window. This bar must
cover the entire code.
Effective scanning is obtained by tilting the scanner with respect to
the bar code to avoid direct reflections, which impair the reading
performance (see Figure 1A below). A successful read is signaled by
an audible tone or a jingle (previously uploaded), plus a good-read
green spot. The side and upper illuminators become green (unless
another color has been configured with Aladdin configurator).
Once the reader is correctly inserted into the stand, it is immediately
ready to automatically read any code present in its reading area
without pressing the trigger. Furthermore, a red pattern (central
cross and four spots located in corners) is continuously emitted to
facilitate the aiming of the bar code to be read (shown in Figure 1B).
To guarantee single code reading, consecutive reading of the same
code requires the code to be removed from the reading area (no
decoding) before the reader will accept the same code again.
