参照EOCR-3典型接线图完成接线。
根据实际情况将功能开关选择在合适的位置上（参照上述说明）。
接通工作电源，按下述方法设置参数。
□ 过电流值设置顺时针方向转动面板上的“MODE/Adjust ”钮至 位置。
这里0.5表示过电流值0.5A 。
若要改变此值，需按 “SET/store ”键，然后转动“MODE/Adjust ”钮，上述的值即可改变。
把这个值调整到电机铭牌上规定的额定值上（如无此值，推荐将此值放在电机实际运行电流的110-125%之间）。
再次按动“SET/store ”键，将该值存贮起来即可，若设置值超过10A 时，需将功能开关SW4 拨到60位置上，用前述方法调整到所需数值，如果超过60A ，则应根据需要配相应的外部互感器，并按第13条要求操作。
2.起动延时时间设置过电流值设置完成后，再将“MODE/Adjust ”钮顺时针方向转动，即可看到 显示。
dt 表示起动延时；10表示延时时间为10秒。
电机起动时其起动电流要达到电机额 定运转电流的5-7倍。
电机的起动电流在其转数没有达到额定 转数的80%之前并不减少；当达到额定转数的80%以后起动电 流急剧下降至额定电流值（过电流设定值）以下。
电流变化曲 线与过电流设定值交叉点的时间就是电机起动延时时间D-TIME （参见右图）。

The MultiModem ISI server card provides four or eight dial-up sessions using only one server slot. When demand exceeds one modem card, you can simply add up to three additional cards.V.92 Dial-out Connections. The MultiModem ISI server card supports V .92/56K dial-out and V .34/33.6K dial-inconnections. With V .92 dial-out, you can achieve an upload speed of 48K bps (30% increase over V .90 modems).Enhanced Fax Features. The MultiModem ISI server card supports V .34 fax and Error Correction Mode providingsignificant performance and reliability enhancements over previous fax standards. V .34 sends and receives faxes at speeds up to 33.6K, more than double the speed of the V .17/14.4K fax standard. Error Correction Mode adds reliablility while increasing performance of faxtransmissions. Together these enhancements increase the performance of the MultiModem ISI server card to levels previously only found in more expensive dedicated fax boards and machines.V.44 Compression. V .44 compression standard improves V .42bis data compression anywhere from 20 to 60%, up to as much as 200% for certain types of highly compressible data. This compression technique enables data throughput rates of higher than 300K bps.Simplify Remote Access. The fully-integrated MultiModem ISI server card is easy to set up and manage. You only have to connect the phone lines. There are no external modems and power cords to hassle with; plus it saves back office space since the modems are on the prehensive Service and Support. The Multi-Techcommitment to service means we provide a two-year product warranty and service that includes free telephone technical support, 24-hour web site and ftp support.Ordering InformationProductDescriptionRegion ISI5634UPCI/8 V .92, 8-Modem Card - Universal PCI Global ISI5634UPCI/4 V .92, 4-Modem Card - Universal PCI Global ISI9234PCIE/8 V .92, 8-Modem Card - PCI Express Global ISI9234PCIE/4V .92, 4-Modem Card - PCI ExpressGlobalSpecificationsModemData: V .92, V .90, enhanced V .34, V .32bis, V .22bis Error Correction: V .42, MNP Class 3 & 4Data Compression: V .44, V .42bis, MNP Class 5FaxStandards: V .34, V .17, V .29, V .27ter, V .21, T.30, T.30Annex A, T.30 Annex F , T.31, T.31 Annex B, T.32 Annex C, TR29.2 Class 2 RecommendationRates: 33.6K, 31.2K, 28.8K, 26.4K, 24K, 21.6K, 19.2K, 16.8K, 14.4K, 12K, 9600, 7200, 4800, 2400, 300 bps Error Correction: ECMCompression: MH (T.4), MR (T.4), & MMR (T.6)Conversion: Real time (on-the-fly) compression conversionCommands: Class 1, 2, 1.0, 2.0, 2.1Bus Type3.3V & 5V Universal PCI or PCI Express (x1)Operating System SupportWindows 2000/XP/2003/Vista/2008 (32-bit/64-bit) & LinuxCablingFan out cable with 1 or 2 RJ45 connectors & 4 or 8 RJ11 connectorsPhysical DescriptionUniversal PCI Models:13.87" L × 4.97" W; 8.7 oz (35.2 cm × 12.6 cm; 247 g)PCI Express Models:13.87" L × 4.97" W; 8.5 oz (35.2 cm × 12.6 cm; 241 g)Operating EnvironmentTemperature Range: +23° to +140° F (-5° to +60° C)ApprovalsCE MarkEMC: FCC Part 15 Class B, EN 55022, EN 55024Safety: UL/cUL 60950-1, EN 60950-1, AS/NZS 60950:2000, CCCTelecom: 47CFR Part 68, CS03, TBR21Other countries also includedCopyright © 2008 by Multi-Tech Systems, Inc.

小身材大内涵-Dell PowerEdge R420评测
小身材大内涵-Dell PowerEdge R420评测作者：暂无来源：《计算机世界》 2012年第32期■ 计算机世界评测实验室于泽自英特尔至强E5 系列处理器上市以来，各大厂商纷纷对各自的服务器产品线进行升级。
Dell 也不例外，相继推出了一系列新产品，也就是戴尔第十二代（12G）服务器。
相较上一代产品，12G 服务器在性能以及虚拟化的支持上有了很大的提升。
本次测试的是DellPowerEdgeR420( 以下简称R420)，它是戴尔专为满足中小型企业一般需求或大型企业高IT 密度及性能需求而推出的一款产品。
设计篇外形方面，R420 采用1U 高度设计，而且在前后面板空间利用上几乎做到极致。
前面板除了8 个2.5英寸硬盘插槽外，还配有光驱以及电源按钮、NMI 按钮，系统识别按钮，LCD 面板及VGA、USB 等多种接口。
背面板同样紧凑、合理，不仅有PCIe 扩展插槽，串行接口、VGA 接口、USB 接口、网络接口等常见的配置，还配有vFlash 卡插槽，这在以往的服务器配置中可不常见。
R420 的内部布局同样错落有致，虽然是1U 服务器，但其最多可配备两颗至强E5-2400 系列处理器，最多可拥有16 个物理核心；搭配12 个DIMM 插槽，最多可达到192GB 的内存容量，对于当下大热的虚拟化环境，可以有不错的支持；另外，R420 最多可搭载8 个2.5 英寸热插拔SAS、SATA 或SSD 驱动器或4 个3.5 英寸热插拔硬盘，最大存储容量可达到12TB。
当然，如此多的部件散热问题不容小觑，这方面R420 搭载6 个小型风扇，以保证整台机器的散热。
在实际测试中，R420 交出了满意的答卷，整个测试过程中并没有出现过热的情况。
另外值得一提的是，R420 所配备的iDRAC 7 卡，通过与服务器主板上的管理芯片BMC 进行通信，监控、管理服务器的硬件状态信息。
由于它直接嵌入主板内，所以与服务器上的OS无关，对于管理员而言是个不错的工具。

protel_dxp_2004常用元器件中英文对照及基本封装
protel dxp 2004 元件库中的常用元件初学protel DXP 碰到最多的问题就是：不知道元件放在哪个库中。
这里我收集了DXP2004常用元件库下常见的元件。
使用时，只需在libary中选择相应的元件库后，输入英文的前几个字母就可看到相应的元件了。
通过添加通配符*，可以扩大选择范围。
下面这些库元件都是DXP 2004自带的不用下载。
########### DXP2004下Miscellaneous Devices.Intlib元件库中常用元件有：电阻系列（res*）排组（res pack*）电感（inductor*）电容（cap*，capacitor*）二极管系列（diode*，d*）三极管系列（npn*，pnp*，mos*，MOSFET*，MESFET*，jfet*，IGBT*）运算放大器系列（op*）继电器（relay*）8位数码显示管（dpy*）电桥（bri*bridge）光电耦合器( opto* ，optoisolator )光电二极管、三极管（photo*）模数转换、数模转换器（adc-8，dac-8）晶振（xtal）电源（battery）喇叭（speaker）麦克风（mic*）小灯泡（lamp*）响铃（bell）天线（antenna）保险丝（fuse*）开关系列（sw*）跳线（jumper*）变压器系列（trans*）（tube*）（scr）（neon）（buzzer）（coax）晶振（crystal oscillator）的元件库名称是Miscellaneous Devices.Intlib, 在search栏中输入*soc 即可。

CD4094中文资料
*4094 与74ls164 的编程使用区别，仅仅在于多了一个1脚锁存端口。
当1脚为高电平时，其使用方法与164一模一样。
各位老师可以在以前164驱动的程序里，直接将加入将1脚置为高电平即可。
**另外，当1脚为低电平时，其输出引脚被锁定，Q引脚输出数据不会变化。
**但当锁存（1脚为低电平时），你跟4094通讯，可以使其内部数据改变，改变后，将1脚置为高电平，其Q输出引脚会被立即更新。
CD4094 位移位存储总线寄存器: CD4094是带输出锁存和三态控制的串入/并出高速转换器，具有使用简单、功耗低、驱动能力强和控制灵活等优点。
CD4094的引脚定义如图1。
其中(1)脚为锁存端，(2)脚为串行数据输入端，(3)脚为串行时钟端。
(1)脚为高电平时，8位并行输出口Q1～Q8在时钟的上升沿随串行输入而变化；(1)脚为低电平时，输出锁定。
利用锁存端可方便地进行片选和级联输出控制。
(15)脚为并行输出状态控制端，(15)脚为低电平时，并行输出端处在高阻状态，在用CD4094作显示输出时，可使显示数码闪烁。
(9)脚QS、(10)脚Q′S是串行数据输出端，用于级联。
QS端在第9个串行时钟的上升沿开始输出，Q′S端在第9个串行时钟的下降沿开始输出.当CD4094电源为5V时，输出电流大于3．2MA，灌电流为1 MA。
串行时钟频率可达2．5MHZ。

PCA9555
......................................................................................................................................................... SCPS131E – AUGUST 2005 – REVISED MAY 2008
The PCA9555 consists of two 8-bit Configuration (input or output selection), Input Port, Output Port, and Polarity Inversion (active high or active low operation) registers. At power on, the I/Os are configured as inputs. The system master can enable the I/Os as either inputs or outputs by writing to the I/O configuration bits. The data for each input or output is kept in the corresponding Input or Output register. The polarity of the Input Port register can be inverted with the Polarity Inversion register. All registers can be read by the system master.

e5ezr控制器说明书
e5ezr控制器说明书当产品在本手册描述的环境或情况下使用时，一定要遵守额定值及功能限制。
此外，为保证安全，请采用如安全安装等应对措施。
本产品应用于以下场合时须事先向弊公司洽询:使用条件及环境在本手册中未注明。
使用在核能控制、铁路、航空、车辆、焚烧装置、医疗器材、娱乐器材、安全器材等时。
使用在可能会影响人身安全或造成财产损失以及对安全性有特殊要求的场合时。
安全符号本手册使用以下符号标记E5EZ-PRR温度控制器中的安全注意事项。
这些注意事项提供了关于本产品安全应用的重要信息。
必须确保遵守所有安全注意事项中的指导。
请确保遵守以下注意事项以保证安全使用。
(1)在各型号规定的温度和温度范围内使用和储藏温控器，当二个和多个温控器水平紧靠安装或垂直紧靠安装时，由于温控器的热辐射会导致内部温度上升而降低使用寿命。
这种情况下，需要采取风扇强制冷却或其它通风措施来降低温控器的温度，但是，小心不要单冷却接线端部分以避免造成测量误差。
(2)为了不妨碍散热，温控仪周边请勿封闭。
温控仪本身的通风孔也不要堵塞。
(3)电源电压及负载，请在规格、式样范围内使用。
(4请确认端子的极性，做正确的配线。
(5)配线用压接端子请使用指定尺寸(M3.5、宽7.2mm 以下)的端子。
最大为7.5(6)配线用材料，请使用AWG24（截面积0.205mm')~AWG14(截面积2.08Imm')的电线，剥线长度:5~6mm(7)不使用的端子，请勿连接。
( 8)电源投入时,请在2秒内达到额定工作电压。
(9)可直接由前盖取出的温控仪，在取出前需先关闭电源，请绝对不要用手触摸端子或电子部品，或者给予冲击。
插回时，请不要让电子部品与外壳接触。
(10)使用自调节时，同时打开温度控制器和负载（如加热器)，或在温度控制器打开前接通负载。
如果在接通负载前打开温度控制器电源，则不能再进行正确的自调节和实现最优控制。
预热完成后开始操作，预热一完成即断开电源，然后同时打开温度控制器和负载。

Output
If the load circuit is a heating control system, be sure to connect the load to terminals 4 and 5. If the load circuit is a cooling control sys-tem, be sure to connect the load to terminals 4 and 6. If the heating control system is connected to terminals 4 and 6 or the cooling con-trol system is connected to terminals 4 and 5, the temperature of the heating control system or cooling control system will be abnormal and a serious accident may result.
If the E5C4 is in frequent operation, such as proportional operation,add an appropriate external relay to the E5C4 by considering the ca-pacity of the load and the life of the relay.
Do not ground the output of any E5C4 that has voltage output, other-wise the process temperature may not be accurate.
Power Supply
If a single power supply is used for the E5C4 and the load, the supply voltage of the power supply may vary greatly when the load is open or closed if the capacity of the power supply is not large enough.Make sure that the capacity of the power supply is large enough so that the supply voltage range will be always from 90% to 110% of the rated supply voltage.
The E5C4 operates at either 50 or 60 Hz.
