Comtrol RocketPort Plus uPCI Quad DB25 99428-2 Leaflet

Part number 99428-2

• RoHS Directive 2002/95/EC compliant

• Universal PCI design supporting 3.3 and

5.0 Volt PCI bus architectures— ensures
compatibility with all current PCI bus
architectures 

• I/O mapping capabilities—simplifies

installation, eliminates memory conflicts,
and enables plug-and-play compatibility 

• Multiport serial expansion using a single

slot—maximizes host expansion
capabilities; adds four COM ports using
only one slot 

• On-board dedicated 44MHz RISC

processor—minimizes "host" CPU
utilization 

• RS-232 communications support—enables

transmit-and-receive speeds up to 921
Kbps 

• DB25 fan-out cable—provides cost-

effective, compact, and flexible serial
connections

• Transmit buffers 16 times larger, and

receive buffers 64 times larger, than a
16550 UART—helps ensure smooth,
efficient data transfer

• Robust driver support—enables card to

work seamlessly with popular operating
systems

The Comtrol RocketPort Plus uPCI Quad/DB25 serial port expansion card
provides four “native” serial ports utilizing a single PCI card slot and is
compatible with all current 3.3 and 5.0 Volt PCI bus architectures. The
DB25 serial ports support RS-232 serial communications at speeds up to
921 Kbps. Every RocketPort serial card features the high-performance
RocketPort ASIC chip, consisting of a dedicated 44MHz processor that
minimizes host CPU utilization and larger transmit-and-receive buffers than
those of 16550 UART chips used in standard PC serial ports and low-end
serial cards. RocketPort ASIC technology enables these cards to
outperform other serial expansion cards by handling the transmission of
large amounts of data more reliably and efficiently. Additionally, RocketPort
products do not require the assignment of interrupts, simplifying installation
and eliminating conflicts with other server cards. The product is fully
compliant with the European Directive RoHS 2002/95/EC.
