The RocketPort EXPRESS 4J serial port expansion card provides
four “native” serial ports utilizing a single PCIe card slot and is compatible
with all PCI Express bus architectures. The RJ45 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 44 MHz core that minimizes
host CPU utilization and optimizes data transmission via larger transmitand-
receive 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 4J the
perfect solution for projects requiring PC-based serial communication.
