The RocketPort uPCI Octa/DB25 serial port expansion card is compatible with all current 3.3 and 5.0 Volt PCI bus architectures. It provides eight "native" serial ports utilizing a single 32- or 64-bit PCI card slot. The serial ports with DB25 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. Drivers are available for popular operating systems. The product is fully compliant with the RoHS directive 2002/95/EC.
