ADAM-4520快速入门手册
• ADAM-4520/4522快速入门手册一、ADAM-4520/4522概述ADAM-4520/4522是有源的RS-232到RS-422/485的转换器，无须任何软件驱动，硬件配置正确即可实现转换功能。
RS-485端带有硬件自动数据流控制（自动流控，Automatic data flow），使用时无须额外进行软件自动流控；信号端具有3000V隔离保护，这样就有效的防止模块在收到高压冲击时而损坏。
DCADAM-4520/4522外观与ADAM-4000系列数据采集模块完全相同，安装方式有导轨安装、壁挂安装等，也可以与ADAM-4000数据采集模块叠加在一起。
波特率最高可以达到115.2kbps，使用10V-30V直流电源供电。
出厂默认设置：参数 设置波特率（Baud Rate） 9600bps数据格式（Data format）10bits二、常规使用方法图1 ADAM-45204522连接示意图通过使用ADAM-4520，可以将主机（或PLC）上的RS-232串口转换为RS-422/485串口，从而实现连接更多设备、延长通讯距离等功能。
注意：当一对一通讯的时候，也可以反向使用，即将RS-485串口转换为RS-232串口，但是需要注意的是，ADAM-4520/4522无法设置RS-485设备的地址，因此反向使用时仅能用于一对一通讯！三、ADAM-4520/4522使用前必读1. ADAM-4520/4522连接一般PC机时，RS-232端应该使用串口直连线。
由图1可知，一般PC机的DB-9针串口，管脚2为Rx，管脚3为Tx；而4520的管脚2为Tx，管脚3为Rx；根据RS-232需要交叉Rx与Tx的要求，一般PC机与4520连接时使用串口直连线即可。
2. 使用RS-485/422通讯时，需要设置数据格式。
SW1用来设置数据格式，可以是9、10、11、12位（bits）。
默认的数据格式是10bits：1起始位，8数据位，0校验位，1停止位。

supply decoupling capacitors are not shown in these diagrams.For more detail on the use and operation of fully differential op amps see application report Fully-Differential Amplifiers (SLOA054).The THS4520is a fully differential op amp,and can be used to amplify differential input signals to differential output signals.A basic block diagram of Figure 34.Single-Ended Input to Differentialthe circuit is shown in Figure 33(CM input not Output Amplifier shown).The gain of the circuit is set by R F divided by R G .The input common-model voltage of a fully differential op amp is the voltage at the '+'and '–'input pins of the op amp.It is important to not violate the input common-mode voltage range (V ICR )of the op amp.Assuming the op amp is in linear operation,the differential voltage across the input pins is only a few millivolts at most.So finding the voltage at one input pin determines the input common-mode voltage of the op amp.Treating the negative input as a summing node,the voltage is given by Equation 1:Figure 33.Differential Input to Differential OutputAmplifier To determine the V ICR of the op amp,the voltage atthe negative input is evaluated at the extremes of

CommScope FA4520x-03 EDFA高输出、平锐化单槽光传输器说明书
DATA SHEET Optical Node Series (NC)FA4520x-03 EDFA High Output, Gain Flattened, Single Slot Optical AmplifiersThe CommScope FA4520E ‐03, FA4520F ‐03, and FA4520H ‐03 modules are high ‐output, gain ‐flattened, extremely compact optical amplifiers with an output power limiting function that limits the optical output power to ensure compliance with Class 1M laser products. These high ‐performance amplifiers allow operators to use 1550 nm DWDM transmitters over the extended optical range between ITU channels 14 to 62 to deliver high ‐quality, full spectrum broadcast and digital narrowcast content over significant transmission distances in applications where a flat amplifier gain spectrum is required.These third ‐generation optical amplifiers introduce a microprocessor to offer significant enhancements in the deployment of traditional HFC, Fiber Deep, and fiber to the home (FTTH) networks. The modules can be user selectable to operate in two modes, either constant current which delivers a fixed optical output power, typically used for single wavelength deployments; or constant gain, which is intended for multiwavelength applications where the optical level per wavelength remains constant as the number of wavelengths is increased, within the constraints of the total operating power.•Gain Flattened for C ‐Band•20 dBm output power•Extended op cal range ITU Channels 62−14,1527.9−1566.3 nm•User ‐selectable Constant Current or ConstantGain mode•User settable output level•Extended optical input sensor range ‐30 to +10dBm•Low noise figure•Optical path isolation (input and output)•Remote status monitoring and control•Full auto ‐recovery•ASE muting with variable threshold•Auto ‐limiting optical output for eye safety•Hot plug ‐in/out FEATURESThis latest model offers extended amplification of optical input range down to ‐26 dBm per wavelength* to better support low level data signals. Input sensor range is extended down to ‐30 dBm. The automatic ASE muting has user settable thresholds where the EDFA output is muted when the incoming optical signal is below the threshold value with optical power automatically restored when the signal returns.*See detailed specifications regarding minimum input power and OSNR.Operational monitoring has been increased. This includes remote monitoring of optical levels, laser operating conditions, and alarm status with the option to set alarm parameters to suit local operating conditions.The units are designed as plug‐in modules for CommScope’s NC4000™series Fiber Node Platforms, including the NH4000 “Virtual Hub” and Universal Virtual Hub (UVHub), and, when used in the latter, provides a practical alternative to OTN‐style cabinets.SPECIFICATIONSPhysicalDimensions 4.0” L x 2.2” H x 2.3” W (10.2 cm x 5.6 cm x 5.8 cm)Weight0.6 lbs(0.3 kg)EnvironmentalOperating Temperature Range‐40°to +85°C (‐40°to 185°F)Storage Temperature Range‐40°to +85°C (‐40°to 185°F)Humidity5% to 95% non‐condensingGeneralHot plug‐in/outModes of Operation Constant Current or Constant GainASE Muting User enable/disable.

无线吸顶式 AP
第2章 工作模式
AP支持两种工作模式：FAT AP模式和FIT AP模式。 当用户需要组建的无线网络规模较小时，可以使用FAT AP模式。此模式下，AP支持Web界面 管理，用户可以登录AP的Web管理界面进行无线功能设置，管理网络中的无线客户端，设置 AP的网络参数等。 当用户需要组建的无线网络规模较大时，若单独管理网络中的每一个AP，将使得网络管理工 作繁琐且复杂。此时，推荐用户在网络中搭建一台TP-LINK无线控制器产品，由无线控制器 统一管理网络中的所有AP。此情况下，AP只需工作在FIT AP模式即可。
此开关用于切换AP工作模式。切换模式后，AP将自动重启。 当开关拨到FAT时，表示AP工作在FAT AP模式。此模式适用于AP数量较少的网络环境，此模 式下，AP支持Web界面管理，可以登录Web界面对AP进行单独管理。FAT AP模式Web界面 管理方法，请参考2.1 FAT AP模式。 当开关拨到FIT时，表示AP工作在FIT AP模式。此模式适用于AP数量较多的网络环境，由AP 组建的局域网中需要接入TP-LINK无线控制器，可以登录无线控制器管理界面对本产品进行 功能配置。无线控制器的使用方法，请参考对应机型的说明书。 RJ45 接口

How does Braun ThermoScan work?
Braun ThermoScan measures the infrared heat generated by the eardrum and surrounding tissues. To help to avoid inaccurate temperature measurements, the probe tip is warmed to a temperature close to that of the human body. When the Braun ThermoScan is placed in the ear, it continuously monitors the infrared energy. The measurement is finished and the result displayed when the thermometer detects that an accurate temperature measurement has been taken.
there is a risk of cross-contamination.

注意：当一对一通讯的时候，也可以反向使用，即将RS-485串口转换为RS-232串口，但是需要注意的是，ADAM-4520/4522无法设置RS-485设备的地址，因此反向使用时仅能用于一对一通讯！三、ADAM-4520/4522使用前必读1. ADAM-4520/4522连接一般PC机时，RS-232端应该使用串口直连线。
由图1可知，一般PC机的DB-9针串口，管脚2为Rx，管脚3为Tx；而4520的管脚2为Tx，管脚3为Rx；根据RS-232需要交叉Rx与Tx的要求，一般PC机与4520连接时使用串口直连线即可。
2. 使用RS-485/422通讯时，需要设置数据格式。
SW1用来设置数据格式，可以是9、10、11、12位（bits）。
默认的数据格式是10bits：1起始位，8数据位，0校验位，1停止位。
当使用ADAM-4000模块时，默认设置即可通讯。
当使用其它厂家产品时，如果通讯参数不是“N,8,1”，则需要根据通讯参数来设置SW1。

These speeds shouldbe avoided during operation. For a safe operation of theunit we recommend to remain approx. 30 % below orabove the critical speeds.▪After installation depending on speed the unit should bebalanced according to DIN 2060.▪The machine vibrations should be checked according toVDI 2056.LiteratureDubbel pocket book for machine engineering, published bySpringer.F.

Radial and torsional vibrations may have a very bad impact on the performance of the torque shaft and the measuring signal.For that reason the operating speed must not be near the critical speed, either it has to be far underneath or above it.BrakeHalf couplings Type 2302A...

No.: 18008943) with low capacity.As supply and evaluation unit we suggest the Control Monitor CoMo Torque Type 4700B... .The matching connection cable is Type KSM018538-2,5 (Mat. No.: 18008963).As an alternative solution the units Type 4704A…, model VA3600 without display can be used.Assembly set Type KSM035681 (Mat. No.: 18024830) as accessories for VA3600 for the connection of the torque measuring shaft Type 4520A… .The signal lead should not exceed a length of 30 meters. Do not run the lead parallel to power cables or control cir-cuits.The pin connection is explained in chapter "Plug Connec-tion" of this manual.On each side of the torque measuring shaft there is a high quality bearing installed. The installation can have any po-sition, however offset couplings must always be applied to balance geometrical errors and keep false loads away from the torque measuring shaft.Radial, axial, diagonal and angular errors are compensa-ted by:▪ Multi-disk couplings, e.g. Type 2303A... ▪ Membran ▪ Claw couplingsType 4500B…Type 4704A…Basic Line Torque Sensor Type 4520A...6.3 Supply and EvaluationThe sensor may only be operated using filtered 24 VDC voltage.Recommended supply voltage:Fig. 12: Supply circuit and evaluationType 4704A...
