RocketPort ® Universal PCI 16-Port

This RocketPort universal PCI 16-Port serial card is compatible with all current 3.3 and 5.0 Volt PCI bus architectures

Part Number: 99355-1

  • Universal PCI design supporting 3.3 and 5.0 Volt PCI bus architectures
  • I/O mapping capabilities
  • Multiport serial expansion utilizing a single PCI slot
  • Standard IT rackmount RJ45 and surge protected DB25 interfaces available
  • On-board dedicated 36MHz RISC processor
  • RS-232/422 interfaces on each port
  • Transmit buffers 16 times larger, and receive buffers 64 times larger than a 16550 UART
  • Robust driver support

The RocketPort uPCI 16-Port serial expansion card is compatible with all current 3.3 and 5.0 Volt PCI bus architectures. It provides 16 "native" serial ports utilizing a single PCI card slot and an external serial interface module available sold separately that supports RS-232 or RS-422 serial communications at speeds up to 230 Kbps. Individual serial ports on the same interface module can be configured for either RS-232 or RS-422 communication. External interface modules with additional surge protection are also available.

RocketPort products are designed with larger transmit-and-receive buffers than those of a 16550 UART found in typical 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 2 directive under CE.
