RELIANCE 45C224可編程控制器
USB連接器（J8）通用串行總線（USB）端口使用行業(yè)標(biāo)準(zhǔn)的四位屏蔽連接器。圖A-5顯示了USB連接器的引腳。鍵盤(pán)/鼠標(biāo)連接器引腳鍵盤(pán)/鼠標(biāo)接口是標(biāo)準(zhǔn)的6針迷你DIN PS/2連接器，如圖A-6所示。鍵盤(pán)/鼠標(biāo)Y形電纜連接到VMIVME-7740上的鍵盤(pán)/鼠標(biāo)連接器，并為鍵盤(pán)和鼠標(biāo)提供了一個(gè)單獨(dú)的連接器。VMIVME-7780包含一個(gè)適配器電纜，用于分離鍵盤(pán)/鼠標(biāo)接頭VMEbus連接器引腳。圖a-7顯示了VMEbus P1和P2連接器的位置及其方向。表A-2和表A-3顯示了VMEbus連接器的引腳分配。VMIVME-7740通過(guò)基于PCI的板載適配器和相關(guān)軟件驅(qū)動(dòng)程序提供高性能視頻和局域網(wǎng)（LAN）訪問(wèn)。VMIVME-7740上使用的AGP視頻控制器是Intel 69030。Intel 82559以太網(wǎng)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
