RS485中文资料(全)
RS-485RS485 接口RS485 采用差分信号负逻辑，＋2V～＋6V 表示“1”，- 6V～- 2V 表示 “0”。
RS485 有两线制和四线制两种接线，四线制是全双工通讯方式，两 线制是半双工通讯方式。
在 RS485 通信网络中一般采用的是主从通信方式， 即一个主机带多个从机。
很多情况下，连接 RS-485 通信链路时只是简单地 用一对双绞线将各个接口的“A”、“B”端连接起来。
而忽略了信号地的 连接，这种连接方法在许多场合是能正常工作的，但却埋下了很大的隐患， 这有二个原因：(1)共模干扰问题： RS-485 接口采用差分方式传输信号方 式，并不需要相对于某个参照点来检测信号，系统只需检测两线之间的电 位差就可以了。
但人们往往忽视了收发器有一定的共模电压范围，RS-485 收发器共模电压范围为-7～+12V，只有满足上述条件，整个网络才能正常 工作。
当网络线路中共模电压超出此范围时就会影响通信的稳定可靠，甚 至损坏接口。
(2)EMI 问题：发送驱动器输出信号中的共模部分需要一个返 回通路，如没有一个低阻的返回通道（信号地），就会以辐射的形式返回 源端，整个总线就会像一个巨大的天线向外辐射电磁波。
RS485 同 RS232 连接由于 PC 机默认的只带有 RS232 接口，有两种方法可以得到 PC 上位机 的 RS485 电路：（1）通过 RS232/RS485 转换电路将 PC 机串口 RS232 信号 转换成 RS485 信号，对于情况比较复杂的工业环境最好是选用防浪涌带隔 离珊的产品。
（2）通过 PCI 多串口卡，可以直接选用输出信号为 RS485 类 型的扩展卡。
RS485 电缆在低速、短距离、无干扰的场合可以采用普通的双绞线，反之，在高 速、长线传输时，则必须采用阻抗匹配（一般为 120Ω）的 RS485 专用电缆 （STP-120Ω（for RS485 & CAN） one pair 18 AWG），而在干扰恶劣的 环境下还应采用铠装型双绞屏蔽电缆（ASTP-120Ω（for RS485 & CAN） one pair 18 AWG）。

BiMOS II 8-BIT SERIAL-INPUT,LATCHED DRIVERSAlways order by complete part number, e.g., UCN5821A .Data Sheet 26185.12E5821 AND 5822A merged combination of bipolar and MOS technology gives these devices an interface flexibility beyond the reach of standard logic buffers and power driver arrays. The UCN5821A,UCN5821LW, UCN5822A, and UCN5822LW each have an eight-bit CMOS shift register and CMOS control circuitry, eight CMOS data latches, and eight bipolar current-sinking Darlington output drivers. The UCN5821A/LW and UCN5822A/LW are identical except for rated output voltage.BiMOS II devices have much higher data-input rates than the original BiMOS circuits. With a 5 V logic supply, they will typically operate at better than 5 MHz. With a 12 V supply,significantly higher speeds are obtained. The CMOS inputs are compatible with standard CMOS and NMOS logic levels. TTL circuits may require the use of appropriate pull-up resistors. By using the serial data output, the drivers can be cascaded for interface applications requiring additional drive lines.The UCN5821/22A are furnished in a standard 16-pin plastic DIP; the UCN5821/22LW are in a 16-lead wide-body SOIC for surface-mount applications. The UCN5821A is also available for operation from -40°C to +85°C. To order, change the prefix from ‘UCN’ to ‘UCQ’.FEATURESI To 3.3 MHz Data Input Rate I CMOS, NMOS, TTL Compatible I Internal Pull-Down ResistorsI Low-Power CMOS Logic & Latches I High-Voltage Current-Sink Outputs I Automotive Capable5821 AND 58228-BIT SERIAL-INPUT,LATCHED DRIVERS115 Northeast Cutoff, Box 15036Worcester, Massachusetts 01615-0036 (508) 853-5000Copyright © 1985, 2000, Allegro MicroSystems, Inc.5821 AND 5822 8-BIT SERIAL-INPUT, LATCHED DRIVERS LimitsCharacteristic Symbol Test Conditions Min.Max.Units Output Leakage I CEX UCN5821A/LW, V OUT = 50 V—50µACurrent UCN5822A/LW, VOUT= 80 V—50µAUCN5821A/LW, V OUT = 50 V, T A = +70°C—100µAUCN5822A/LW, V OUT = 80 V, T A = +70°C—100µA Collector-Emitter V CE(SAT)I OUT = 100 mA— 1.1VSaturation Voltage IOUT= 200 mA— 1.3VI OUT = 350 mA, V DD = 7.0 V— 1.6V Input Voltage V IN(0)—0.8VV IN(1)V DD = 12 V10.5—VV DD = 5.0 V 3.5—V Input Resistance r IN V DD = 12 V50—kΩV DD = 5.0 V50—kΩSupply Current I DD(ON)One Driver ON, V DD = 12 V— 4.5mAOne Driver ON, V DD = 10 V— 3.9mAOne Driver ON, V DD = 5.0 V— 2.4mAI DD(OFF)V DD = 5.0 V, All Drivers OFF, All Inputs = 0 V— 1.6mAV DD = 12 V, All Drivers OFF, All Inputs = 0 V— 2.9mA ELECTRICAL CHARACTERISTICS at T A = +25°C, V DD = 5 V, (unless otherwise specified).5821 AND 58228-BIT SERIAL-INPUT,LATCHED DRIVERS115 Northeast Cutoff, Box 15036Worcester, Massachusetts 01615-0036 (508) 853-5000TIMING CONDITIONS(V DD = 5.0 V, T A = +25°C, Logic Levels are V DD and Ground)A.Minimum Data Active Time Before Clock Pulse(Data Set-Up Time).......................................................................75 ns B.Minimum Data Active Time After Clock Pulse(Data Hold Time)...........................................................................75 ns C.Minimum Data Pulse Width..............................................................150 ns D.Minimum Clock Pulse Width ............................................................150 ns E.Minimum Time Between Clock Activation and Strobe.......................30 ns F.Minimum Strobe Pulse Width...........................................................100 nsG.Typical Time Between Strobe Activation andOutput Transition ..........................................................................1.0 µsL = Low Logic Level H = High Logic Level X = Irrelevant P = Present State R = Previous StateDwg.

FEATURES AND SPECIFICATIONS SPECIFICATIONS MTP* OpticalRound Ribbon Cable Assemblies 86282Molex's MTP round jacketed ribbon cable assemblies provide easier installation than traditional flat ribbon cables in optical networks. System designers and installers have found it difficult to route flat ribbon cable in complex networks. The use of round ribbon cables allows the installer greater flexibility when routing multiple jacketed cables in dense system networks.Molex developed a patent pending transition sleeve which maintains the routing features of the round cable while allowing the cable to be secured to the MTP connector. The primary benefit of the round ribbon cable is realized with the use of multiple ribbons within a single jacket. Stacked ribbons in traditional flat jacketed ribbon cables are prone to piston in relation to each other, causing attenuation in longer cable assemblies. The round ribbon cable prevents the “pistoning” effect by encasing the ribbons in a solid buffer core, preventing them from moving. Fiber counts up to 24 fibers are currently available while development continues on the 48 and 72 fiber versions.Reference Information Packaging: Custom per assembly Mates With: MPO and MTP Connectors (86081 & 86082 Series)OpticalFiber Specifications:Core: 50µm†Clad: 125µmCoating: 250µmInsertion Loss (IL):12F: 0.15 dB Typ. <0.5dB max.24F: 0.25 dB Typ. <0.75dB max.72F: 0.35 dB Typ. <1.00dB max.

RoHS Compliance Statement
None of the following materials are intentionally added in manufacturing this product: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) or polybrominated diphenyl ethers (PBDE) as outlined in the Directive 2002/95/EC Article 4.1. See Desco Industries Inc. letter on-line at .
Description:
Conductive Lightly Embossed Top Layer
.50"
Insulative foam rubber sponge base
Desco’s Statfree® AFR mat is made with a conductive nitrile rubber top black layer and an anti-fatigue foam rubber bottom layer. The product is designed to provide a flooring surface that does not generate a static charge and will act as part of the path to ground for an operator wearing ESD footwear. The resistance range (10E4 – 10E5 ohms Rtt) of the top black layer will remain low enough to act as a path to ground with normal dirt and grime build up on a floor and meet the required limit of ANSI/ESD S20.20 Method 1 (<3.5 x 10E7 ohms) for a flooring/footwear system. The bottom foam rubber layer is designed to reduce standing workers’ fatigue and improve productivity. Ultra-violet (UV) stabilizer additives are included in the Nitrile rubber compound to stabilize color retention, ensure ESD performance over time and eliminate surface layer deterioration resulting in cracking when the product is flexed. Each mat is lot coded for quality control and lifespan tracking. Note: Not intended for use with chairs, carts, or wheels.

MAX488_全球某工商版中文资料
MAX488By cl1.概述双路单刀双掷无源开关，全双工，0.25Mbps(无源只是转换，有源除了实现232和485转换外还能保证两者之间的电气隔离)VCC，大于等于4.75V，小于等于5.25V，静态电流120uA1.1.RS485RS-485以差动方式发送和接收，两线间电压差为+(2~6)V表示逻辑1，-(2~6)V表示逻辑0，差动工作是同速率条件下传输距离远的根本原因（可达几十米到上千米）；电压比RS232降低了，不易损坏接口电路的芯片，且该电平与TTL电平兼容，方便与TTL电路连接；最高速率10Mbps1.2.RS232RS232-C是EIA(美国电子工业协会Electronic Industry Association)制定的一种串行物理接口标准。
RS是英文“recommended standard(推荐标准)”的缩写，232为标识号，C表示修改次数。
设有25条信号线，包括一个主通道和一个辅助通道。
在多数情况下主要使用主通道，对于一般双工通信，仅需几条信号线就可实现，如一条发送线、一条接收线及一条地线。
RS-232-C标准规定的数据传输速率为每秒50、75、100、150、300、600、1200、2400、4800、9600、19200波特。
RS-232-C标准规定，驱动器允许有2500pF的电容负载，通信距离将受此电容限制；例如，采用150pF/m的通信电缆时，最大通信距离为15m；若每米电缆的电容量减小，通信距离可以增加。
传输距离短的另一原因是RS-232属单端信号传送，存在共地噪声和不能抑制共模干扰等问题，因此一般用于20m以内的通信。
2.封装RO：接收输出(Receiver Output)，当A端电压比B端电压高超过200mV，RO输出高当A端电压比B端电压低200mV以上，RO输出低DI：驱动输入,低电平不能低于-0.5V，高电平不能高于VCC+0.5V 输入低电平时Y输出低，Z输出高；输入高电平时Y输出高，Z输出低3.应用。

FEATURES AND SPECIFICATIONS SPECIFICATIONS MTP* Optical
Round Ribbon Cable Assemblies 86282
Molex's MTP round jacketed ribbon cable assemblies provide easier installation than traditional flat ribbon cables in optical networks. System designers and installers have found it difficult to route flat ribbon cable in complex networks. The use of round ribbon cables allows the installer greater flexibility when routing multiple jacketed cables in dense system networks.
Molex developed a patent pending transition sleeve which maintains the routing features of the round cable while allowing the cable to be secured to the MTP connector. The primary benefit of the round ribbon cable is realized with the use of multiple ribbons within a single jacket. Stacked ribbons in traditional flat jacketed ribbon cables are prone to piston in relation to each other, causing attenuation in longer cable assemblies. The round ribbon cable prevents the “pistoning” effect by encasing the ribbons in a solid buffer core, preventing them from moving. Fiber counts up to 24 fibers are currently available while development continues on the 48 and 72 fiber versions.
