RELIANCE 45C224可编程控制器
USB连接器（J8）通用串行总线（USB）端口使用行业标准的四位屏蔽连接器。图A-5显示了USB连接器的引脚。键盘/鼠标连接器引脚键盘/鼠标接口是标准的6针迷你DIN PS/2连接器，如图A-6所示。键盘/鼠标Y形电缆连接到VMIVME-7740上的键盘/鼠标连接器，并为键盘和鼠标提供了一个单独的连接器。VMIVME-7780包含一个适配器电缆，用于分离键盘/鼠标接头VMEbus连接器引脚。图a-7显示了VMEbus P1和P2连接器的位置及其方向。表A-2和表A-3显示了VMEbus连接器的引脚分配。VMIVME-7740通过基于PCI的板载适配器和相关软件驱动程序提供高性能视频和局域网（LAN）访问。VMIVME-7740上使用的AGP视频控制器是Intel 69030。Intel 82559以太网控制器芯片提供高性能LAN操作，包括10BaseT和100BaseTx
USB Connector (J8) The Universal Serial Bus (USB) port uses an industry standard, four position shielded connector. Figure A-5 shows the pinout of the USB connector.Keyboard/Mouse Connector Pinout The keyboard/Mouse connector is a standard 6-pin female mini-DIN PS/2 connector as shown in Figure A-6. The Keyboard/Mouse Y-cable connects to the Keyboard/Mouse connector on the VMIVME-7740 and provides a separate connector for both Keyboard and Mouse.An adapter cable is included with the VMIVME-7740 to separate the Keyboard/Mouse Connector VMEbus Connector Pinout Figure A-7 shows the location of the VMEbus P1 and P2 connectors and their orientation. Table A-2 and Table A-3 show the pin assignments for the VMEbus connectors.The VMIVME-7740 provides high-performance video and Local Area Network (LAN) access by means of on-board PCI-based adapters and associated software drivers. The AGP video controller used on the VMIVME-7740 is the Intel 69030. High-performance LAN operation, including 10BaseT and 100BaseTx, is provided by the Intel 82559 Ethernet controller chip
