    The PCIe-AC51 is compatible with computers using the PCI Express bus. These cards are an ideal choice when replacing an older PC with an ISA bus connected to an Opto 22 AC28 or PCI-AC28 adapter card. (The AC28 and PCI-AC28 adapter cards are not recommended for new designs.

  • Page 6: What's In This Guide

    Each PCI-AC51 and PCIe-AC51 connects to one Pamux bus, and each Pamux bus consists of up to 512 I/O points. To easily address and reference so many points, Opto 22 brains and software logically group the I/O into banks, which are sets of eight consecutive points.

  • Page 24: Understanding The Pamux Bus Reset Line

    Understanding the Pamux Bus Reset Line This section explains the terminology and functioning of the Pamux bus reset line and its interaction between the PCI-AC51 or PCIe-AC51 card and the Pamux brains. The Reset Line The purpose of the reset line on the Pamux bus is to provide a way to reset all the brains in the system to their default powerup state.

  • Page 25: Brain Reset Configuration: "Active High" And "Active Low

    One consideration is how you want your system to function if the computer loses power. Without power to the computer, the PCI-AC51 or PCIe-AC51 cannot drive the reset line high, so by default it will be low. You would want to analyze your system needs to determine what is necessary for your system to automatically go into failsafe mode.

    Inp() and Outp() function calls at the user level are unsupported because of the Windows hardware abstraction layer.

    ARCHITECTURE Architecture The PCI-AC51 and PCIe-AC51 cards contain an Altera FPGA (U8 on the PCI-AC51 and U1 on the PCIe-AC51). The Altera FPGA implements the PCI or PCI Express interface to the host computer, regulating data transactions between the host computer and the adapter card while also providing adapter card configuration information to the host computer's BIOS.
