PSC's powerful and versatile multi-interface decoders, MASTER B+ and MASTER BB+, allow you to connect a variety of input devices to more than 2,000 different terminals and PCs. The MASTER B+ features dual input ports for connection of undecoded and RS-232 devices, including wands, CCD scanners, laser scanners, badge readers, magnetic stripe readers, POS scanners, scales, and OCR readers. The MASTER B+ also features dual communication ports, one for host connection and the other for auxiliary input. Host communication modes supported include keyboard wedge, RS-232, RS-485 multidrop, OCIA, and wand, MSR and laser emulation. In addition, adapters are available for RS-422, 20 mA current loop, and vocal frequency. More than a decoder, the MASTER B+ functions as a powerful and flexible bar code data collection system controller. The MASTER B+ can serve as a netdriver or satellite on PSC's RS-485 SMARTNET, and can control devices via relay actuation. Programming the MASTER B+ is easy, with three available methods, including bar code menus, downloading software, and cloning. The MASTER B+ auto-discriminates and decodes up to 21 different bar code symbologies.
