The NI PCI-MXI-2 is a half-size, PCI-compatible plug-in circuit board that links your PCI-based computer directly to the MXIbus and vice versa by plugging into one of the expansion slots. This interface card achieves high performance block transfer rates by integrating the MITE custom ASIC with standard interfaces for VXI, VME, MXI, and PCI.

The PCI-MXI-2 is viewed as a VXIbus device since it uses the same communication register set as as other VXIbus devices use. This card can also function as the MXIbus System Controller.

The NI PCI-MXI-2 (Part Number: 777185-01, 182685K-01) is part of the MXI-2 Series by National Instruments. This Circuit Board can be inserted into an expansion slot on the user’s PCI-based computer. The PCI-MXI-2 connects the user’s PCI-based computer straight to the MXIbus and the other way around. Since the PCI-MXI-2 utilizes an identical communication register set to other VXIbus message-based instruments, other MXIbus instruments see the PCI-MXI-2 as a VXIbus instrument. This Plug-in Circuit Board supports D64, block, and synchronous MXI cycles for high-performance information transfer, supports MXI bus termination, and conforms to both PCI specification 2.0 and MXIbus specification 2.0. The device has a programmable memory space of 32 kb minimum, with a data path of 32 bits.

The NI PCI-MXI-2 Plug-In Circuit Board has an onboard EEPROM, which saves default register values that load when the model powers on. The EEPROM has two sections: a factory-configuration section and a user-configuration section. The factory-configured part of the model saves a back-up of the default user settings, while the user-configured part can be altered. The factory configuration is a minimal configuration, which enables the user to boot the PCI-MXI-2 despite modifications to the user configuration. When changing settings, do not modify the settings of switches 3 and 4 of U17.
