RocketPort® Plus uPCI 422 Octa DB9

Product Discontinued

The RocketPort® Plus uPCI 422 Octa DB9 is discontinued and has been replaced with the RocketPort ® INFINITY Octa DB9M (3000-7). This product page is being maintained for product and support information.

Universal PCI 8-Port serial card with DB9M fanout cable, supports RS-422 communications, at speeds up to 921Kbps

Part Number: 99402-2

  • RoHS 2 compliant under CE
  • Universal PCI design supporting 3.3 and 5.0 Volt PCI bus architectures – ensures compatibility with all current PCI bus architectures
  • I/O mapping capabilities – simplifies installation, eliminates memory conflicts, and enables plub-and-play compatibility
  • Multiport serial expansion using a single slot – maximizes host expansion capabilities; adds additional COM ports using only one slot
  • On-board dedicated 44MHz RISC processor – minimizes "host" CPU utilization
  • RS-422 communications support – enables transmit-and-receive speeds up to 921 Kbps
  • Fan-out cable – provides cost-effective, compact, and flexible serial connections
  • Transmit buffer 16 times larger, and receive buffers 64 times larger than a 16550 UART – helps ensure smooth, efficient data transfer
  • Robust driver support – enables card to work seamlessly with popular operating systems

The Comtrol RocketPort Plus uPCI 422 Octa/DB9 serial port expansion card provides eight "native" serial ports utilizing a single PCI card slot and is compatible with all current 3.3 and 5.0 Volt PCI bus architectures. The DB9 serial ports support RS-422 serial communications at speeds up to 921 Kbps.

Every RocketPort serial card features the high-performance RocketPort ASIC chip, consisting of a dedicated 44MHz processor that minimizes host CPU utilization and larger transmit-and-receive buffers than those of 16550 UART chips used in standard PC serial ports and low-end serial cards. RocketPort ASIC technology enables these cards to outperform other serial expansion cards by handling the transmission of large amounts of data more reliably and efficiently.

Additionally, RocketPort products do not require the assignment of interrupts, simplifying installation and eliminating conflicts with other server cards. The product is fully compliant with the RoHS 2 directive under CE.
