PCI-MXI-2 插接式电路板 支持 MXI 总线终端

☆型号：PCI-MXI-2      插接式电路板    支持 MXI 总线终端 

【产品详情】

NI PCI-MXI-2是National Instruments的MXI-2系列的一部分。该电路板可以插入用户基于PCI的计算机上的扩展插槽中。 PCI-MXI-2 将用户基于 PCI 的计算机直接连接到 MXIbus，反之亦然。由于 PCI-MXI-2 使用与其他基于 VXIbus 消息的仪器相同的通信寄存器，因此其他 MXIbus 仪器将 PCI-MXI-2 视为 VXIbus 仪器。该插入式电路板支持 D64、块和同步 MXI 周期，以实现高性能信息传输，支持 MXI 总线终端，并符合 PCI 规范 2.0 和 MXIbus 规范 2.0。该器件的可编程存储器空间最小为 32 kb，数据路径为 32 位。

NI PCI- MXI-2 插 接 式 电路 板 具有 一个 板 载 EEPROM， 可 保存 模型 上 电 时 加载 的 默认 寄存 器 值。EEPROM有两个部分：工厂配置部分和用户配置部分。模型的出厂配置部分保存默认用户设置的备份，而用户配置的部分可以更改。出厂配置是最低配置，即使修改了用户配置，用户仍可以启动PCI-MXI-2。更改设置时，请勿修改 U3 的开关 4 和 17 的设置。

PCI-MXI-2使用NI-VXI/NI-VISA软件运行，并与LabVIEW、LabWindows/CVI和Measurement Studio等软件包兼容。可以使用测量和自动化浏览器（MAX）工具配置该设备。

特征：

将 PCI 总线连接到 MXIbus（32 位多系统扩展接口总线）

支持 D64、块和同步 MXI 周期，实现高性能数据传输

直接控制 MXIbus 中断电平、实用信号、TTL 触发器和 CLK10

符合 PCI 规范 2.0

符合 MXIbus 规范 2.0

支持 MXI 总线终端

National Instruments PCI-MXI-2 是一款半尺寸、兼容 PCI 的插入式电路板，可通过插入其中一个扩展插槽将基于 PCI 的计算机直接连接到 MXIbus，反之亦然。该接口卡通过将 MITE 定制 ASIC 与 VXI、VME、MXI 和 PCI 的标准接口集成，实现高性能块传输速率。

PCI-MXI-2 被视为 VXIbus 设备，因为它使用与其他 VXIbus 设备相同的通信寄存器集。该卡还可以用作 MXIbus 系统控制器。

【英文介绍】

The NI PCI-MXI-2 is part of National Instruments' MXI-2 family. The board can be plugged into an expansion slot on the user's PCI-based computer. PCI-MXI-2 connects the user's PCI-based computer directly to MXIbus and vice versa. Because PCI-MXI-2 uses the same communication register as other VXIbus message-based instruments, other MXIbus instruments treat PCI-MXI-2 as a VXIbus instrument. The plug-in board supports D64, block, and synchronous MXI cycles for high-performance information transfer, supports MXIbus terminals, and complies with PCI specification 2.0 and MXIbus specification 2.0. The device has a minimum of 32 kb of programmable memory space and a 32-bit data path.

The NI PCI-MXI-2 plug-in circuit board has an onboard EEPROM that saves the default register values loaded when the model is powered on. The EEPROM has two parts: the factory configuration part and the user configuration part. The factory configuration part of the model keeps a backup of the default user Settings, while the user configuration part can be changed. The factory configuration is the minimum configuration, and the user can start PCI-MXI-2 even if the user configuration is modified. When changing the Settings, do not modify the Settings of switches 4 and 17 of U3.

PCI-MXI-2 runs with NI-VXI/NI-VISA software and is compatible with packages such as LabVIEW, LabWindows/CVI, and Measurement Studio. The device can be configured using the Measurement and Automation Browser (MAX) tool.

Features:

Connect the PCI bus to MXIbus (32-bit Multi-System Extension Interface Bus)

Supports D64, block, and synchronous MXI cycles for high-performance data transfer

Direct control of MXIbus interrupt levels, utility signals, TTL triggers and CLK10

Conforms to PCI specification 2.0

Conforms to MXIbus specification 2.0

Supports MXI bus terminals

The National Instruments PCI-MXI-2 is a half-size, PCI-compatible plug-in board that connects PCI-based computers directly to MXIbus and vice versa by plugging into one of the expansion slots. The interface card achieves high performance block transfer rate by integrating MITE custom ASics with the standard interfaces of VXI, VME, MXI and PCI.

PCI-MXI-2 is considered a VXIbus device because it uses the same communication register set as other VXIbus devices. The card can also be used as an MXIbus system controller.
