Description

PMC237C-008EMI VME系统的PMC扩展卡

特性
•扩展主机处理器到各种pmc插槽
•32位PCI在主PCI总线上
•PCMCIA/CardBus选项
•选择PCMCIA卡安装在机箱外

PMC237C-008EMI是一款6U规格卡，可将vmebus处理器板上的单个PMC站点扩展为两个PMC站点和一个epcmcia /CardBus插槽或三个PMC站点。它与许多VMEbus单板计算机兼容，在VMEbus形式因素内提供PCI和pcmcia容量的扩展。PMC237C-008EMI可以选择使用18英寸电缆将PCMCIA/CardBus卡安装在机箱外。功能上，pmc237由PCI/PCI桥(确保符合PCI加载)和可选的PCI/PCMCIA主机总线适配器(参见GE发那科智能平台PCMCIA/PC卡主机总线适配器)组成。全PCI带宽可以维护到安装在PMC237上的pmc设备。

PMC237C-008EMI提供多种配置，适合板载功能和主机SBC连接。该板可以填充三个pmc模块，或两个PMC模块和一个PCMCIA/PCCardBus插座。

PMC237C-008EMI为板载设备产生+3.3 V电压。PMC237仅从VMEbus获取电源(5v)和接地。

PMC237C-008EMI VME系统的PMC扩展卡

Features
• Expands the Host Processor to a variety ofPMC slots
• 32-bit PCI on the primary PCI bus
• Option for PCMCIA/CardBus
• Option for PCMCIA cards to be mountedoutside chassis

The PMC237C-008EMI is a 6U form factor card thatexpands a single PMC site on a VMEbusprocessor board to either two PMC sites and onePCMCIA/CardBus socket or to three PMC sites. Compatible with many VMEbus single boardcomputers, it provides an extension of PCI andPCMCIA capacity within the VMEbus form factor. The PMC237C-008EMI has the option for the PCMCIA/CardBus cards to be mounted outside the chassisusing an 18 inch cable. Functionally, the PMC237consists of a PCI/PCI bridge (assuring compliancewith PCI loading) and an optional PCI/PCMCIAHost Bus Adapter (see the GE Fanuc IntelligentPlatforms PCMCIA/PC Card Host Bus Adapters). Full PCI bandwidth can be maintained to PMCdevices installed on the PMC237.

The PMC237C-008EMI offers several configurations tailoringonboard functionality and host SBC connections. The board can either be populated with three PMCmodules, or two PMC modules and a PCMCIA/PCCardBus socket.

The PMC237C-008EMI generates the +3.3 V for the onboarddevices. The PMC237 takes only Power (5 V) andGround from the VMEbus.
