MXI-Express Gen 2 x8 extends PCI Express communication over a cable of up to 5 m. With MXI-Express Gen 2 x8, you can do the following: Control a PXI Express or CompactPCI Express backplane with a PCI Express- ■...
  • Page 5 PCIe-8383 Manual Basic MXI-Express Gen 2 x8 Systems The simplest MXI-Express Gen 2 x8 system consists of a PCIe-8383 in a PC connected to a PXIe-8381 in the controller slot of a PXI Express chassis, as shown in the following figure.
  • Page 6 PCIe-8383 Manual The PCI specification allows up to 256 bus segments. MXI-Express Gen 2 x8 does not limit this number, but the maximum number of bus segments allowed can be BIOS or operating system dependent. Also, a computer may already have several PCI bus segments internally, and the MXI-Express Gen 2 x8 link also has multiple PCI buses internally.

    The following list defines the minimum required hardware and software for a system that includes a PCIe-8383. Note Refer to the NI Hardware and Software Operating System Compatibility page linked below for driver, desktop operating system, and real-time operating system support for individual hardware devices.
  • Page 9 Since this is the primary function of MXI-Express Gen 2 x8 products, those systems may not boot or function correctly. To help address this issue, NI offers MXI-Express BIOS Compatibility software. If you need to use this software, you must toggle the BIOS DIP switch on the board to enable BIOS compatibility.
  • Page 10 Cables Refer to the following table for the various MXI-Express x8 copper cables available from NI. The NI MXI-Express x8 copper cables use Molex x8 PCIe connectors. For more information about these connectors visit Molex at www.molex.com and search for x8 PCIe iPass.

  • Page 14: Dip Switch

    PCIe-8383 Manual DIP Switch The PCIe-8383 has a DIP switch with four switches, which can be found on the top- left corner of the board as shown in the PCIe-8383 block diagram. Refer to the PCIe-8383 Theory of Operation page linked below to view the block diagram.
  • Page 15 (left). CLK Switch The CLK sets the clocking mode. The PCIe-8383 supports two clocking modes: spread spectrum clocking (SSC) and constant frequency clocking (CFC). SSC can reduce radiated emissions and some types of electrical noise in the system. The CLK switch is set to SSC mode by default.
