Comtrol RocketPort Plus uPCI Octa DB25 99427-5 Fascicule

Part number 99427-5

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 eight 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 Octa/DB25 serial port expansion card
provides eight “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
DB25M 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. R

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.
