UAC326AE01控制模块,ABB使用配置说明
MVME2603/2604单板计算机在符合FCC标准的底盘，满足A级设备的要求。FCC合规性是在以下条件下实现的：❏ 所有外部输入/输出端口上的屏蔽电缆。❏ 通过金属外壳连接器连接至接地的电缆屏蔽连接至导电模块前面板。❏ 导电底盘导轨连接至接地。这提供了将屏蔽层连接到接地的路径。❏ 前面板螺钉正确拧紧。
UAC326AE01控制模块对于最小射频发射，必须满足上述条件已实施。如果不这样做，可能会影响FCC的合规性包含模块的设备。介绍如本手册前几章所述，MVME2603/2604串行通信接口有四个端口。其中两个是组合的同步/异步端口；另外两个只是异步的。同步和异步端口都提供EIA-232-D通过P2和MVME712M转换模块的DCE/DTE接口。异步串行端口MVME2603/2604使用National的PC87308 ISASIO芯片半导体实现两个异步串行端口（在除了磁盘驱动器控制器、并行输入/输出和键盘/鼠标之外接口）。ISASIO设备提供的异步端口通过P2和相关的转换模块。TTL电平信号来自ISASIO芯片通过TTL驱动器和串联电阻器进行缓冲，然后通过EIA-232-D驱动器和接收器完成到MVME712M转换的异步串行接口单元MVME2603/2604硬件支持异步串行波特率110B/s至38.4KB/s。有关详细编程信息，请参阅MVME2600系列单板中PCI和ISA总线的讨论附录D中列出的《计算机程序员参考指南》，相关文档，以及ISASIO设备的供应商文档。同步串行端口MVME2603/2604使用Zilog Z85230 ESCC（增强串行通信控制器）使用10 MHz时钟来实现两个路由的同步/异步串行通信端口通过P2连接至过渡模块。Z85230可以同时处理这两个问题
FCC Compliance
The MVME2603/2604 single board computer was tested in an
FCC-compliant chassis and meets the requirements for Class A equipment.
FCC compliance was achieved under the following conditions:
❏ Shielded cables on all external I/O ports.
❏ Cable shields connected to earth ground via metal shell connectors
bonded to a conductive module front panel.
❏ Conductive chassis rails connected to earth ground. This provides
the path for connecting shields to earth ground.
❏ Front panel screws properly tightened.
For minimum RF emissions, it is essential that the conditions above be
implemented. Failure to do so could compromise the FCC compliance of
the equipment containing the module.Introduction
As described in previous chapters of this manual, the MVME2603/2604
serial communications interface has four ports. Two of them are combined
synchronous/asynchronous ports; the other two are asynchronous only.
Both synchronous and asynchronous ports supply an EIA-232-D
DCE/DTE interface via P2 and the MVME712M transition module.
Asynchronous Serial Ports
The MVME2603/2604 uses a PC87308 ISASIO chip from National
Semiconductor to implement the two asynchronous serial ports (in
addition to the disk drive controller, parallel I/O, and keyboard/mouse
interface).
The asynchronous ports provided by the ISASIO device are routed through
P2 and the associated transition module. The TTL-level signals from the
ISASIO chip are buffered through TTL drivers and series resistors, then
routed through EIA-232-D drivers and receivers to complete the
asynchronous serial interface enroute to the MVME712M transition
module.
The MVME2603/2604 hardware supports asynchronous serial baud rates
of 110B/s to 38.4KB/s. For detailed programming information, refer to the
PCI and ISA bus discussions in the MVME2600 Series Single Board
Computer Programmer’s Reference Guide, listed in Appendix D, Related
Documentation, and to the vendor documentation for the ISASIO device.
Synchronous Serial Ports
The MVME2603/2604 uses a Zilog Z85230 ESCC (Enhanced Serial
Communications Controller) with a 10 MHz clock to implement the two
synchronous/asynchronous serial communications ports, which are routed
through P2 to the transition module. The Z85230 handles both
