descripción

The Digi AccelePort Xr 920, one of the industry’s best known multiport serial I/O cards, was designed for use in multi-user (retail point-of-sale, industrial control processing, data collection and office automation) and Remote Access Service (RAS) applications.

The AccelePort Xr 920 Family includes two-, four- and eight-port models, all with wide application flexibility and scalability. Available in PCI Universal Card (3.3V/5V), EIA-232 and EIA-422 versions, these serial cards provide an extremely wide variety of operating system support and accessories (fan-out cables and external I/O connector boxes), and an extra dose of multi-strike surge protection on each and every pin. All these elements contribute to the reasons why leading resellers and systems integrators have specified the Digi AccelePort Xr 920 Family in their designs.

An on-board 32-bit IDT RISC processor delivers high performance with speeds up to 921.6 Kbps. CPU utilization is optimized by efficiently handling serial I/O communication interrupts, character processing and data transfers. Hardware/software flow control ensures the absolute data integrity required for your most active remote access applications and “mission-critical” multi-user environments.
