The Model 20II's state-of-the-art scanning optics are designed to take the guesswork out of fixed position scanning applications. The unit's flexibility and performance allow it to read the most commonly used bar code densities at predefined mounting distances. Using surface mount technology, a solidstate laser, and a brushless DC motor, we have designed a scanning system into one of the smallest packages available. The NEMA 12 extruded aluminum enclosure measures just 2.6 x 2.3 x 1.6 inches (6.6 x 5.8 x 4.1 cm) and provides protection for internal components in almost any harsh industrial environment.
The Model 20II uses an advanced RISC microprocessor to decode scanned data at very high rates and perform various application functions. The standard configuration provides 13 code types with autodiscrimination of eight bar code symbologies at once. Two parallel outputs selectable for valid and non-valid codes provide external signals to operate small relays. Our Accu-Setup Suite program provides easy-to-use Windows�-based scanner setup (terminal or host on-line commands are also available). The Model 20 communicates to the host via RS-232-C, RS-422, RS-485 mulitdrop, or optional 20mA current loop (active or passive). The compact Model 20 optical decoding and I/O features can accommodate a wide variety of scanning applications. Its small size and single power source enable easy integration into automatic test equipment, blood and chemical analyzers, document scanning systems, print verification, or any fixed position bar code scanning application requiring low-cost non-contact bar code scanners. |
