Product Description
Comtrol’s RocketPort EXPRESS 8J serial port expansion card provides
eight “native” serial ports utilizing a single PCIe card slot and is compatible
with all PCI Express bus architectures. The RJ11 serial ports, mounted on
the edge of the card, support software configurable RS-232/422/485 serial
communications at speeds up to 921.6 Kbps.
Every RocketPort serial card features the high-performance RocketPort
processor chip, consisting of a dedicated 44MHz core that minimizes host
CPU utilization and optimizes data transmission via larger transmit-andreceive buffers than those of 16550 UART chips commonly, used in standard
PC serial ports and low-end serial cards.

RocketPort technology enables these cards to outperform other serial
expansion cards by handling the transmission of large amounts of data more
reliably and efficiently.
Certified Windows drivers, support for the most popular operating systems,
and readily available U.S.-based support makes the RocketPort 8J the
perfect solution for projects requiring PC-based serial communication.
