Product Overview
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
• A serial controller
• Bus interface logic and other miscellaneous logic
You can install up to four RocketPort PCI 422 cards in one PC, with up to 32
additional serial ports, and you can install any combination of PCI-bus and ISA-
bus RocketPort cards.
