DESCRIPTION: The BD
Series of fixed beam barcode scanning products feature
integral decoding circuitry and ASCII format output data. The
units are available with either visible red and infrared light
sources. The viewing area is elliptical rather than circular,
with the long axis of the ellipse parallel to the bars,
resulting in higher read rates than units with circular
viewing areas. All major functions are user configurable
using a serial data terminal, enabling the
unit to be customized to a particular application.
Configuration information is held in nonvolatile EEPROM, so
configuration data is not lost when power is removed. The
unit reads and decodes seven standard industrial barcode
symbologies and automatically recognizes the type of code
being scanned when more than one type is configured. Barcode
data is output in serial ASCII format at RS-232 or
RS-422 levels. All communications parameters are user
configurable. The unit operates from a single five volt power
supply and is contained in an anodized aluminum housing.
TYPICAL APPLICATIONS:
These units are designed to read and decode barcode symbols
passing the scanner in a known orientation and at a specific
distance range. The model with a visible red light source is
used in most scanning applications. It can read codes where
the bars are printed in black or other colors, except red.
Infrared units are used in high visible ambient light
conditions, in photographic applications where film may be
fogged by visible light or in situations where infrared
transparent films are placed over the barcode for security.
The output can be connected directly to a host computer
serial port without external circuitry. SPECIFICATIONS:
