RocketPort ISA

High Performance Serial Connectivity

The Easiest Way to Add COM Ports to Your PC System

When you find that you have more serial devices than ports, RocketPort® offers a quick, cost-effective solution. Each RocketPort adds 4 to 32 “native” COM ports to your PC server or PC client using only a single  PC slot—and no IRQs. The Comtrol RocketPort family of multiport cards makes serial connectivity more powerful, reliable, easier to use, and more cost effective than any other controller available today.

Features/Benefits

• Leading price/performance for any multiport card
• Up to 32 COM ports can be added in a single slot without using any IRQs
• Dedicated 36 MHz Application Specific Integrated Circuits (ASIC) processors, one per every eight ports, for optimum performance
• ASIC integration reduces the number of components by 80%, yielding unmatched reliability and the industry’s highest Mean Time Between Failure (MTBF)
• Superior performance—up to 460 Kbps* transmit-and-receive across all ports simultaneously—sustains fully compressed ISDN throughput
• Both ISDN terminal adapters and modems can be connected to the same card
• I/O mapping eliminates memory conflicts and allows plug-and-play compatibility
• Supports ISA bus architectures, ensuring compatibility regardless of the host environment
• Supports serial interfaces, including RS-232 and RS-422
• Easy installation—no shared memory to configure (and no IRQs required)
• Minimal "host" CPU utilization
• Large FIFOs, 64 times larger than a 16550 UART, maximize speed and minimize data loss while optimizing host efficiency and data integrity
• Comtrol’s superior technical support is readily available to ensure smooth, hassle-free operation

* Non-standard baud rates are dependent on the operating system. Maximum port speed of 460 Kbps is available on models without interfaces. The RocketPort Plus uPCI product family delivers up to 921 Kbps transmit-and-receive across all ports simultaneously.
