 Xr 920
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 
wide range of operating systems and accessories including 
fan-out cables and external I/O connector boxes.
