Baroce Scanner

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.
