Comtrol RocketPort Plus uPCI Quad DB9 99425-1 Fascicule

Part number 99425-1

Highlights

• 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 

• DB9 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/DB9 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 DB9
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 RoHS Directive 2002/95/EC.
