The RocketPort PCI 422 series multiport serial card fits into the PCI slot of a
personal computer, and uses a 36 MHz processor that is specifically designed to
process asynchronous serial communications. The RocketPort PCI 422 supports
RS-422 exclusively, in either DTE or DCE mode.
The RocketPort PCI 422 series uses Application Specific Integrated Circuits
(ASICs) technology to replace most hardware components, including:
The processor
Serial controller
Bus interface logic and other miscellaneous logic
You can install up to four RocketPort PCI 422 cards in one PC, for a total of 32
additional serial ports, and you can install a combination of PCI-bus and ISA-bus
RocketPort cards.
