Add COM Ports to Your PC System Quickly and Easily
Works with 3.3 and 5.0 Volt PCI
RocketPort Universal PCI multi-port cards make serial device connectivity reliable, cost effective, and easy. Add up to 32 "native" COM ports to your PC per card. All Comtrol RocketPort uPCI cards support 3.3 and 5.0 Volt PCI bus architectures and are compatible with 64-bit 66MHz 3.3 Volt slots.
Unique, Powerful ASIC-Based Architecture Means Fast, Reliable, and Efficient Data Throughput
- Fast. The RocketPort Universal PCI card is powered by Comtrol's exclusive RocketPort chip, integrating a dedicated 36MHz processor that enables the card to transmit and receive data four times faster than standard UART technology—up to 460 Kbps full duplex across all ports simultaneously.
- Reliable. The RocketPort chip extremely low failure rate makes our multi-port serial card one of the most reliable on the market.
- Efficient. RocketPort uses transmit FIFOs 16 times larger, and receive FIFOs 64 times larger, than multiport cards designed with 16550 UARTs (Universal Asynchronous Receiver Transmitters). This helps eliminate bottlenecks at the serial controller level while conserving CPU resources.
