  • Page 2: What Is Pxi

    The SMD components used on Schroff PXI backplanes lead to a much lower failure rate than conventional components. Schroff uses ceramic capacitors on the PXI backplanes to gain a better noise reduction at frequencies above 10MHz.

  • Page 3: Schroff Pxi Backplane Features

    ChassisGND conductive spring washers are recommended instead of isolating ones. VI/O Schroff PXI backplanes have a complete power plane for the VI/O voltage. The VI/O plane can be connected using a bridge on the power bugs to +3.3V or +5V.

  • Page 4: Pxi Bridge

    PXI Manual Bridge Applications PXI Bridge CPCI and PXI has been designed to accommodate up to 8 modules on a bus segment. Installing a bridge module on a bus segment consumes one of the loads on the segment but creates a new bus segment with up to 7 additional modules. The bridge module handles all communication between the bus segments.

  • Page 5: Overview Pxi Architecture And Implementation

    PXI Manual PXI Implementation Overview PXI Architecture and Implementation Details of the PXI Architecture can be found in the PXI Specification, downloadable at www.pxisa.org. Bus Interface PXI uses the CompactPCI/PCI Bus to transfer data between CPU and peripheral cards. The maximum throughput for a 32 Bit / 33 MHz system is 132 MB/s, the maximum throughput for a 64 Bit / 66 MHz system is 528 MB/s.

    Local Bus. Schroff PXI Backplanes are designed for a current carrying capacity of 400 mA. The PXI specification only demands 200 mA. If you want to make use of the higher capacity, make sure it is supported by the used peripheral boards.

Confirm by clicking “OK”. The following window looks like this: Page 14 of 25...
  • Page 16 PXI Manual Software Installation, PXI Bridge Click the large button (the computer symbol) to continue installation. By clicking “Verzeichnis wechseln” you can change the installation folder. Setup creates a new program group called “MarekMicro GmbH” and inserts the element “PXI Bridge Configuration”.
  • Page 17 PXI Manual Software Installation, PXI Bridge Double click „System“. Choose the register “Hardware” and click “Device Manager”. Now check the tree named “System Devices” for entries “PCI Standard-PCI-to-PCI-Bridge” and remove these entries by hitting the delete key on your keyboard. Usually it is OK to only remove the uppermost entry as the following entries will then also be removed.
  • Page 18 PXI Manual Software Installation, PXI Bridge In the next window confirm by clicking the “OK” button and restart your system when asked, so Windows can load the driver for the PXI bridge. After rebooting the plug and play manager finds the “new” hardware. Now the correct driver will be installed.

  • Page 19: Pxi Bus Configuration Tool

    PXI Bus Configuration Tool Introduction Schroff PXI Bridges allow cascading of several backplane segments. The first backplane segment, the primary backplane, contains a system slot for the CPU and six peripheral slots. All other backplane segments only contain up to seven peripheral slots for use with PXI modules. The maximal usage with 21 slots looks like this: Use the PXI Bus Configuration Tool to configure the PXI bridges.
  • Page 20 PXI Manual Configuration, PXI Bus In the right column there are the bi-directional and buffered PXI trigger bus signals. Connections in both directions can be used. By clicking any of the signals, an arrow pointing to the secondary side occurs. If a trigger signal to the opposite direction is needed, the signal has to be clicked another time.
