Comtrol RocketPort Plus uPCI Quad/Octa 422 99400-8 Fascicule

Part number 99400-8

• 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 

• Multi-port serial expansion using a single

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

• On-board dedicated 44MHz RISC

processor—minimizes "host" CPU utilization 

• RS-422 communications support—enables

transmit-and-receive speeds up to 921 Kbps 

• 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 422 Quad/Octa Bulk package contains
fifty (50) serial port expansion cards that are compatible with all current
3.3 and 5.0 Volt PCI bus architectures. Depending on the serial cables,
purchased separately, each card provides four or eight “native” serial
ports utilizing a single PCI card slot. The serial ports support RS-422
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 complies with the European RoHS
Directive 2002/95/EC.
