AccelePort® Xr 920
Multiport Serial Cards
Serial card designed for a wide range of applications allows
a variety of parameter settings, superior CPU utilization,
fast data throughput, and extra surge protection on every pin.
Overview
The AccelePort Xr 920 family is one of the industry’s best
known multiport serial I/O cards. Designed for multi-user and
Remote Access Service (RAS) applications, these serial cards
deliver reliable, cost-effective serial port expansion. They are
ideal for use in Point-of-Sale (POS), industrial control
processing, data collection and office automation applications.
An on-board 32-bit IDT RISC processor delivers up to 921.6
Kbps of data throughput. CPU utilization is optimized by the
efficient handling of serial I/O communication interrupts,
character processing and data transfers. Hardware and
software flow control ensures absolute data integrity. The
AccelePort Xr 920 features multi-strike surge protection on
every pin.
The AccelePort Xr 920 family offers wide application flexibility
and scalability. It includes two-, four- and eight-port models
and is available in RS-232 and RS-422 versions. It supports a
