MINNEAPOLIS,Minnesota — June 1, 2011—Comtrol Corporation, a leading manufacturer of industrial device connectivity products, today introduced the RocketPort EXPRESS 4J and 8J PCIe serial port expansion cards. The introduction of these cards complements Comtrol’s RocketPort EXPRESS line of in-server serial cards, the industry’s most complete PCIe product line. These cards provide PCs with four or eight “native” serial ports utilizing a single PCIe card slot, are compatible with all PCI Express bus architectures, and feature standard RJ45 and RJ11 serial connectors for simplified cabling.

Both serial cards feature the high-performance RocketPort processor technology. The RocketPort chip includes a dedicated 44MHz core, which minimizes host CPU utilization and optimizes data transmission via larger transmit and receive buffers than those of 16550 UART chips, which are commonly used in standard PC serial ports and low-end serial cards.

“Comtrol’s RocketPort EXPRESS 4J and 8J cards with integrated serial connectors offer easy installation and clean system integration by eliminating the complexity and cable clutter associated with breakout boxes and fan-out cables, ” said David Boldt, Director of Product Management at Comtrol, “The addition of these PCIe cards creates a simple path for customers transitioning applications from older PCI systems while offering superior solutions for new projects requiring serial expansion on low-power and small form factor PCs.”

Comtrol’s RocketPort technology enables these cards to outperform other serial expansion cards by handling the transmission of large amounts of data more reliably and efficiently. This makes them perfect solutions for projects requiring PC-based serial communication. All RocketPort serial expansion cards support the latest Windows and Linux operating systems, and include free U.S. – based technical support.
