GE IC660ELB912 µGENI 网络接口板
IC660ELB912 是来自 GE Fanuc 的 µGENI 网络接口板。它被设计为用户微处理器系统中的子板。用户可以将 µGENI 和主板连接到任何能够读取和写入 µGENI 上的通用共享 RAM 的 CPU 类型设备中。该设备称为主机。
尽管 RAM 接口针对 IBM 个人计算机总线进行了优化，但它很容易适应各种其他 CPU 类型。 由于它处理主机和 Genius I/O 总线之间的所有数据传输，μGENI 有效地释放了主机。这允许主机控制远程 I/O。它通过使用 Genius I/O 的特性来实现这一点，例如高可靠性和抗噪性。此外，主机可以使用 Genius LAN 的通信功能与其他主机进行通信。
从某种意义上说，μGENI 是一个通用控制器，为 30 多个其他总线设备维护初始化任务和管理故障。每个设备控制一个I/O，μGENI保持每个设备的更新图像。它还能够通过使用全局数据、数据报和定向控制数据消息与其他控制器进行通信。所述μGENI有一系列在其单一的印刷电路板复杂的部件。
它使用 6303 串行接口微处理器将消息写入 MIT 芯片。该芯片管理与总线的硬件接口并提供支持功能。例如，它处理错误检查、LED 驱动器和定时器功能。发送/接收电路与 MIT 和总线发送和接收信号密切配合。
该μGENI采用双口RAM交换数据。这是在 6303 微处理器和管理器微处理器 - 64180 之间完成的。由于两个处理器运行两个独立的系统，双端口 RAM 确保它们都具有平等的访问权限。这由 GAL 控制，以逐字节为基础向任一处理器提供内存。64180 还有一个单独的 8Kb RAM 供其专用。
用户应使用垫片将µGENI安装到主板上。这是通过在主板的四个角孔中放置螺钉、支架或塑料 PCB 支架来完成的。请勿在板上使用任何粘合剂产品。
重要的是µGENI板的安装方式不会阻碍整个板的气流。用户应注意不要将其安装在主板上任何其他板或组件的 1/8 英范围内。
µGENI板需要一个 5V 直流电源来操作逻辑电源。
he IC660ELB912 is a µGENI Network Interface Board from GE Fanuc. It is designed to be a daughterboard in a user’s microprocessor system. Users can interface the µGENI and the motherboard in any CPU-type device capable of reading and writing to the general-purpose shared RAM on the µGENI. This device is known as the host.
Although the RAM interface is optimized for the IBM personal–computer bus, it is easy to adapt to various other CPU types. As it handles all data transfers between the host and the Genius I/O bus, the µGENI effectively frees up the host. This allows the host to control remote I/O. It does this by using the features of the Genius I/O, such as high reliability and noise immunity. Furthermore, the host can use the communication features of the Genius LAN to communicate with other hosts.
In a sense, the µGENI is a general-purpose controller, maintaining initialization tasks and managing faults for over 30 other bus devices. Each device controls an I/O and the µGENI keeps updated images of each one. It is also capable of communicating with other controllers through the use of Global Data, datagrams and Directed Control Data messages.The µGENI has a range of intricate components on its single-printed circuit board.
It uses a 6303-serial interface microprocessor to write messages to the MIT chip. This chip manages the hardware interface to the bus and provides support functions. For example, it handles error checking, LED drivers and a timer function. A transmit/receive circuit works closely with the MIT and bus transmit and receive signals.
The µGENI uses dual port RAM to exchange data. This is done between the 6303-microprocessor and a manager microprocessor - 64180. As the two processors run two separate systems, the dual port RAM ensures they both have equal access. This is controlled by a GAL, delivering memory to either processor on a byte-by-byte basis. The 64180 also has a separate 8Kb of RAM for its exclusive use.
The user should mount the µGENI to the motherboard using spacers. This is done by putting screws, standoffs or plastic PCB supports in the four corner holes of the motherboard. Do not use any adhesive product on the board.It is important that the µGENI board is not mounted in a way that obstructs airflow across the board. Users should take care not to mount it within 1/8 inch of any other board or component on the motherboard.
