VMEbus装配VME-PMC-凯迪是VME64基板，最多可容纳两个单尺寸PMC模块或一个双尺寸模块。Tundra的VME-PCI bridge UNIVERSE II ca91c 142内部时钟频率为33 MHz，用于连接VMEbus。

CA91C142的设计允许电路板在VMEbus上作为从机或主机运行。作为主机，板支持4级仲裁器。VME-PMC-卡迪在VMEbus上以高达32位的数据宽度和32个地址信号运行。
VMEbus中断可以放在七条中断请求线上。根据VME64扩展，通过IEC 603-xx的两个160针VG连接器连接到VMEbus。红色LED表示有效的VMEbus中断请求，前面板上黄色LED表示VMEbus对电路板的访问。

The VMEbus assembly VME-PMC-CADDY is a VME64 base board for accommodating up to two PMC modules in single size or one module in double size. The VME-PCI bridge UNIVERSE II CA91C142 from Tundra with an internal clock rate of 33 MHz is used for connection to the VMEbus.

The design of the CA91C142 allows the board to be operated as a slave or also as a master on the VMEbus. As master the board supports a 4-level arbiter. The VME-PMC-CADDY operates with a data width of up to 32 bits and with 32 address signals on the VMEbus.
The VMEbus interrupt can be placed on any of the seven interrupt request lines. The connection to the VMEbus is made via two 160-pin VG connectors according to IEC 603-xx in accordance with the VME64 extension. An active VMEbus interrupt request is indicated by a red LED and a VMEbus access to the board by a yellow LED in the front panel.

The two PMC slots are designed according to the draft standard IEEE P1286/Draft 2.0 (except for the standard I/O pin routing). All commercially available PMC modules can be fitted. In addition to the transfer connectors for the PMC address/data and control signals, each slot of the VME-PMC-CADDY is equipped with an I/O connector that routes the I/O signals of the PMC modules 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 modules (as per PMC update of FORCETM, Table 1, Author: Wayne Fischer, Director of Strategic Programs CMC/PMC Working Groups Chair, 10/22/96).
In the option ‘-32P’ the pin assignment is carried out according to IEEE P1386/Draft 2.0, Table 6-3. This pinout allows the connection of two PMC modules via P2, since some of the PMC I/O signals are collocated on the P2.
