Comtrol RocketPort Universal PCI Quad DB9

The RocketPort uPCI Quad/DB9 serial port expansion card is compatible with all current 3.3 and 5.0 Volt PCI bus architectures. It provides four "native" serial ports utilizing a single 32- or 64-bit PCI card slot. The serial ports with DB9 connectors support RS-232 serial communications at speeds up to 460 Kbps. RocketPort products are designed with larger transmit-and-receive buffers than those available in a standard 16550 UART found in standard PC serial ports and low-end serial cards, enabling them to handle the transmission of large amounts of data reliably and efficiently. They also utilize an on-board 36MHz processor, minimizing host CPU utilization. RocketPort products do not require the assignment of interrupts, simplifying installation and eliminating conflicts with other server cards.
