VME-PCI 链接

VMEbus 组件 VME-PMC-CADDY 是一个 VME64 基板，最多可容纳两个单一尺寸的 PMC 模块或一个双尺寸的模块。来自 Tundra 的 VME-PCI 桥接器 UNIVERSE II CA91C142，内部时钟频率为 33 MHz，用于连接到 VMEbus。

VMEbus 接口

CA91C142的设计允许该板在VMEbus上作为从站或主站运行。作为主机，该板支持一个 4 级仲裁器。VME-PMC-CADDY 在 VMEbus 上以高达 32 位的数据宽度和 32 个地址信号运行。

VMEbus 中断可以放置在 7 个中断请求行中的任何一条上。通过两个符合 IEC 603-xx 和 VME64 扩展的 160 针 VG 连接器连接到 VMEbus。活动的 VMEbus 中断请求由红色 LED 指示，VMEbus 对主板的访问由前面板中的黄色 LED 指示。

PMC 插件单元

两个 PMC 插槽根据标准草案 IEEE P1286/Draft 2.0 设计（标准 I/O 引脚布线除外）。可以安装所有市售的 PMC 模块。除了用于 PMC 地址/数据和控制信号的传输连接器外，VME-PMC-CADDY 的每个插槽都配备了一个 I/O 连接器，用于将 PMC 模块的 I/O 信号路由到 VMEbus 连接器 P2。

提供两种不同的 P2 引脚分配：在默认配置中，每个 P2 引脚仅连接到 PMC 模块的一个 I/O 引脚（根据 FORCETM 的 PMC 更新，表 1，作者：Wayne Fischer，战略计划总监 CMC/PMC 工作组主席，10 年 22 月 96 日）。

在选项“-32P”中，引脚分配根据 IEEE P1386/Draft 2.0 表 6-3 执行。该引脚排列允许通过 P2 连接两个 PMC 模块，因为一些 PMC I/O 信号并置在 P2 上。

VME-PCI link

The VMEbus component VME-PMC-CADDY is a VME64 substrate that can accommodate up to two single-size PMC modules or one dual-size module. UNIVERSE II CA91C142, a VME-PCI bridge from Tundra with an internal clock frequency of 33 MHz, is used to connect to the VMEbus.

VMEbus interface

The design of CA91C142 allows the board to operate as a slave or master station on a VMEbus. As a host, the board supports a level 4 arbitrator. VME-PMC-CADDY operates on VMEbus with a data width of up to 32 bits and 32 address signals.

VMEbus interrupts can be placed on any of the seven interrupt request lines. Connect to the VMEbus via two 160-pin VG connectors that comply with IEC 603-xx and VME64 extensions. Active VMEbus interrupt requests are indicated by a red LED, and VMEbus access to the motherboard is indicated by a yellow LED in the front panel.

PMC plug-in unit

The two PMC slots are designed according to the Draft standard IEEE P1286/Draft 2.0 (except for standard I/O pin wiring). All commercially available PMC modules can be installed. In addition to the transmission connectors for the PMC address/data and control signals, each slot of the VME-PMC-CADDY is equipped with an I/O connector for routing the I/O signals of the PMC module to the VMEbus connector P2.

Two different P2 pin assignments are available: In the default configuration, each P2 pin is connected to only one I/O pin of the PMC module (according to FORCETM's PMC Update, Table 1, author: Wayne Fischer, Chairman of the CMC/PMC Working Group, Director of Strategic Planning, 22/96).

In the option "-32P", pin assignment is performed according to IEEE P1386/Draft 2.0 Table 6-3. This pin arrangement allows two PMC modules to be connected via P2 because some PMC I/O signals are juxtaposed on P2.
