IntroductionUART/RS232/RS485 are widely used in industrial control and instrument fields. PLC-UART, PLC-RS232/RS485 transceiver modules from LinkSprite (LinkSprite modules) are transceiver modules designed to send/receiver UART/RS232/RS485 data over the powerline network.PLC-RS232/RS485 is designed to transparently move serial data over the powerline network, and achieves the target of replacing RS232/RS485 cables by the ubiquitous powerline network.LinkSprite modules have the built-in packet-level repeater function.This feature can greatly extend the coverage of the powerline communication.LinkSprite modules has both physical and logic addresses. In a network, both physical and logic addresses can be used to address different nodes in the network.2 Features●Fully transparent mode, plug and play coming out of the box withoutthe need to do any programming.● Built-in error correction codes.● Built-in repeater function to extend the coverage.●Physical and logic address●AT commands used for advanced configuration.● UART, RS232 interface and RS485 bus●FSK（Frequency Shift Keying）modulation used in physical layer● Low power● RoHS● Small module size, and easy to be implemented into existingproducts.3 SpecificationsProduct name PLC-UART/RS232/RS485Transceiver ModuleInterface UART, RS232 or RS485Operating Voltage 230VAC/50Hz，110VAC/60HzModulation FSK（Frequency Shift Keying）Carrier frequency 262K/144KHzError Correction FEC（Forward Error Correction）Data rate on Powerline 30KbpsMaximum packet data length 320bytesRepeater Hops 3 HopsTransmission distance 300 feets（no repeater）Support nodes number 65535LED Power Line Activity LEDsystem LEDserial port LED4 Applications●AMR●Industry manufacture and control●Safeguard, fire alarm, smoke alarm●Collect and transmit instrument data●Safeguard and monitor●Home automationⅡDiagram 1 Functional Diagram2 Board Layout3 LEDL1PLC LED: green mans module is sending data to PLC; red means module is receiving data from PLCL2 System LED ，green means system is in normalL3Serial port LED ，green means module is receiving data from aerial port; red means module is sending data to serial port4 Definition of Pin1 VAC 220VAC/50Hz or 110VAC/60Hz Power lines2 VAC 220VAC/50Hz or 110VAC/60Hz3 18V+ +18VDC Module power4 18V- -18VDC5 RS485 B RS485busB RS485 bus6 RS485 A RS485 bus A GND7 GNDGND8RS232TXD RS232 data transmission should link to PC’sRXDRS232 interface9RS232 RXD RS232 data receiving should link to PC’s RXDⅢCommand Interface1 Command Mode1.1 Enter command modeThe module can be put into command mode by sending “+++” through serial port. The module will respond with an “ok”. In order to prevent the situation where the user data” +++”mistakenly triggers the command mode, there must be no serial port data input one second before and after the receiving of "+++". At the same time, the gap between the three”+” should not be more than one second, otherwise, it will be considered as a data rather than a command.1.2 Exit command modeThere are two approaches to exit command mode. One way is to input command “ATEX”. The other is to timeout and automatically exit. In either case, the modules will response "exited". The timeout value can be set by command "ATTO"2 Arguments and Responses2.1 Arguments and ResponsesFor all the commands with arguments: if the parameters are correct, the module will respond with an “ok”. Otherwise, the modules will response with an “invalid para”. If there are no arguments associated with the commands, it will be treated as polling modem and the module will respond with the existing arguments residing in the module.2.2 Commands without ArgumentsThere are four commands without arguments.● + + +: enter command mode; will directly return “ok”.● ATEX: exit the command mode, return “exited”.● ATRS: software reset, will reset the module immediately, no return.● ATSR: in search for other modules on the power lines, this will return thename of the found module. Please wait for two seconds after sending a command. The name of module received in two seconds will be shown in the serial port, otherwise, the name received after two seconds will be ignored. Note: In the course of searching, all bytes input from serial port also will also be ignored.2.3 Modified argumentsExcept for serial arguments, the modified arguments will be immediately saved into eeprom and take effect. The serial arguments won’t take effect immediately after being modified to avoid user from modifying PC serial arguments before inputting command. Serial arguments will take effect through automatically resetting module when exiting the command mode.3 Command ListCommand Description Arguments Description DefaultControl Class+++ none Enter commandmodeATEX Exit none Exit command modeATTO Time out 1-30Timeout value,unit: second5 ATRS Reset none Software resetNetwork classATDA DomainAddress1-32767Domain Address ofLogic Address1ATNANodeAddress1-65535Node Address oflogical address1Function classATRP Repeater Y,N Relay function, Y ison, N for offYATNM NameA stringwith lengthless than 15Set the name of themodulePU-R485A Communication classATBD Baud Rate 1200, 2400,4800, 9600,19200Baud Rate 9600ATDB Data Bit 5,6,7,8 Data bit 8ATPA Parity N, O, E Parity bit，N = no, O= odd, E = evenNATST Stop Bit 1,2 Stop bit 1Debug classATRW Raw Y,NThe raw data for debugging.

It can not only send and receive data from the power line, but also repeat other data packets.In order to prevent network congestion, the module is smart enough to know the data were sent or repeated by itself and will discard the datapackets when receiving the duplicated ones.Note: Due to the fact that repeaters will resent the received data packets, if the number of repeater is too large, a number of repeaters will seize the channel, and lead to increased communication time. When deploying the repeater, one should take full account of the balance of reliability and real-time.2 Function SettingAT command ‘ATRP’ is designed to set up the repeater function.2.1Turn on repeater functionSteps input response description1 +++ ok Enter command mode2 ATRP Y or N Poll current repeater status, Y is on,N for off3 ATRP Y ok Turn on repeater function4 ATRP Y Check present repeat status, ON5 ATEX exit Exit command mode2.2Turn off repeater functionsteps input response description1 +++ ok Enter command mode2ATRPY or NCheck current repeater status, Y is on, N for off3 ATRP N okTurn off repeater function4 ATRP N Check current repeater status, OFF 5ATEXexitExit command mode2.3 Setting Illustration●Repeater function is available in the factory.●Once repeater function is modified; it will immediately take effect and be preserved permanently, even if the module is restarted.3 Repeater HopsA data packet could at most pass through third repeater three times. It is shown as follows ：Data packet is sent from module A to module B. From module B to module C is the first time, to module D is the second time, and to module E is the third time. Module F is the termination. Therefore, data packet won’t be sent to module F.ⅤLogic Address1 Logic AddressModule data packets are transmitted in the way of broadcasting in power lines. All modules will receive the data packets issued by the module and sent them, through the serial port under carrier signals area.When multiple modules are installed on the same power line network, however, one does not want them to communicate directly; thus, the networks can be addressed by the logic address.Logic address is composed of two parts: domain and nodes. For example, the logic address (10:200) means that the domain value is 10, node value is 200. Logic address is the default setting (1:1).Module data packets can only be received and processed by the module at the same domain. Other modules, even detecting the carrier signal will not receive, nor to transmit to the serial port or repeater.On the above figure, A, E are at the same network, their domain values are 1; B, D, F, H are at the same network, its domain values are10;C, G are at the same network, their domain values are 2002. Although in the physically speaking, all the modules are in a power line network, the packet issued by A, will only be received and processed by E, other modules will not respond. Similarly, packet issued by F, only B, D, H will receive and process packet issued by F, other modules will not work.2 Address Settingstep input response description1 +++ ok Enter command mode2 ATDA 1-32767 Check domain values of presentlogic address.

For example, the power meter automatic meter reading systems, data concentrator through the RS485 bus read the message from power meter.In order to automatically meter reading, RS485 bus needs to be deployed. Here, using PU-R485A module, one can use the existed power lines to directly complete data transmission.LinkSprite Technolgies, Inc. 1410 Cannon Mountain Dr. Longmont, CO 80503 (Voice) 720-949-4-932 (Email)******************** 。

TCP Client device will connect to server to realize data transmission between the serial port and server. According to the TCP protocol, TCP Client has connection/disconnection status differences to ensure reliable data transmission. TCP Client mode support Keep-Alive function: After connection is established, module will send Keep-Alive packets about every 15 seconds to check the connection and will disconnect then reconnect to TCP server if abnormal connection is been checked by Keep-Alive packets. TCP Client mode also support non-persistent function.RS485 TO ETH work in TCP Client mode need connect to TCP Server and need set the parameters: Remote Server Addr and Remote Port Number. RS485 TO ETH work in TCP Client won’t accept other connection request except target server and will access server with random local port if user set local port to zero.User can set RS485 TO ETH in TCP Client mode and related parameters by setup software or web server as follows:Figure 6 TCP Client2.2.2.TCP SERVERTCP Server will listen network connections and build network connections, commonly used for communication with TCP clients on a LAN. According to the TCP protocol, TCP Server has connection/disconnection status differences to ensure reliable data transmission.TCP Server mode also support Keep-Alive function.RS485 TO ETH work in TCP Server mode will listen local port which user set and build connection after receiving connection request. Serial data will be sent to all TCP Client devices connected to RS485 TO ETH in TCP Server mode simultaneously.RS485 TO ETH work in TCP Server support 16 client connections at most and will kick off oldest connection beyond maximum connections(User can enable/disable this function by web server). User can set RS485 TO ETH in TCP Server mode and related parameters by setup software or webserver as follows:Figure 7 TCP Server2.2.3. UDP CLIENTUDP transport protocol provides simple and unreliable communication services. No connection connected/disconnected.In UDP Client mode, RS485 TO ETH will only communicate with target IP/Port. If data not from target IP/Port, it won’t be received by RS485 TO ETH.In UDP Client mode, if user set remote IP as 255.255.255.255, RS485 TO ETH can broadcast to entire network segment and receive broadcast data. After firmware version 4015, 304 support broadcasting in same network segment.(Such like xxx.xxx.xxx.255 broadcasting way).User can set RS485 TO ETH in UDP Client mode and related parameters by setup software or web server as follows:2.2.4. UDP SERVERIn UDP Server mode, RS485 TO ETH will change target IP every time after receiving UDP data from a new IP/Port and will send data to latest communication IP/Port.Figure 8 UDP ClientUser can set RS485 TO ETH in UDP Server mode and related parameters by setup software or web server as follows:2.2.5. HTTPD CLIENTIn HTTPD Client mode, RS485 TO ETH can achieve data transmission between serial port device and HTTP server. User just need set RS485 TO ETH in HTTPD Client and set the HTTPD header, URL and some other related parameters, then can achieve data transmission between serial port device and HTTP server and don’t need care about the HTTP format of data.Figure 9 UDP ServerUser can set RS485 TO ETH in HTTPD Client mode and related parameters by web server as follow:Figure 10 HTTPD Client2.3.S ERIAL PORT2.3.1.

红外测温仪RS485串口翻译
6数字通信6.1 RS-485数字通信6.1.1 介绍Modline 5传感器允许RS-485的数字信号与主机中的ASCII编码信息、可编程序逻辑控制器或者其它的RS-485设备实现信息互换。
外部设备可以从传感器和修改传感器的设置从而获取信息。
第五章，90页里有详细的操作规范。
6.1.2基本操作RS- 485数字通信接口可与一个外部设备通过发送消息的形式与传感器实现通信交换，任何传感器消息的发回都有其特定的语言，消息是根据命令列表发送的（具体命令形式下文有说明），包含在消息中的任何数值内容都是十进制和映射值。
每当需要改变传感器的参数或者需要从传感器中获取信息，外部设备必须发送正确的编码和格式化消息。
如果有任何一点错误,传感器都会忽略该消息。
依次，当传感器传送信息回到外部设备时，响应消息将形成相同的标准消息格式。
外部设备必须能够解释响应消息。
命令代码是要求传感器完成所需工作的一部分(如改变数值等)。
要求工作是“写”的命令，使用于“读”命令的相同的代码要求传感器报告其工作状态。
命令代码在这一节中列出。
只有一个命令代码可以用作“读”命令来获得当前状态下的功能和数据。
许多都是用于编写兼容和用于改变设置的命令。
从外部的 RS-485 设备发送而来的读取请求命令消息将导致传感器自动返回状态信息。
例如，如果外部设备发送了一个读的命令让传感器报告发射率的值，传感器会对包含当前辐射率的设置发送一个响应消息。
写命令是由包数值和其他信息的外部设备发送的，这些消息将导致传感器参数的变化。
传感器会回复状态信息。
6.2 RS-485通信传感器后面板设置6.2.1 CLCK-设备锁通信可以配置为允许选择和调整读写功能(R/W)操作或只读(R/O)操作。
只读操作就是让发送到传感器的写命令变成读命令。
6.2.2 ADDR-设置传感器地址单位地址的代码是一位数字或字母。
它从一个数字0到9和大写字母A到Z。
地址出厂默认值设置为0(零)。

The Model 2085 may be configured for high or low impedance operation, carrier may be set to “constantly on” or “controlled by RTS”, and the unit can operate with or without “echo”. RTS/CTS delay may be set for “no delay” or 8 mS.The Model 2085 is equipped with either male or female DB-25 for RS-232 connection. Options for twisted pair connection include terminal blocks with strain relief, RJ-11, RJ-45 and DB-25 male or female. Silicon Avalanche Diodes provide 600 watts per wire of protection against harmful data line transient surges.33.4 CONFIGURATION SWITCH APPLICATIONSThe switch settings generally needed to configure the Model 2085 for various applications are shown in the table below. Note:Do not change switch settings until you have carefully read Section 3.3.84.0 INSTALLATIONOnce you have properly set the configuration switches, you are ready to connect the Model 2085 to your system. This section tells you how to properly connect the Model 2085 to the RS-485 and RS-232 interfaces, and how to operate the Model 2085.4.1 CONNECTION TO THE RS-485 INTERFACETo function properly, the Model 2085 must have one or two twisted pairs of metallic wire. These pairs must be "dry" (unconditioned) metallic wire, between 19 and 26 AWG (the higher number gauges may limit distance somewhat).For your convenience, the Model 2085 is available with several different physical interfaces on the RS-485 side: DB-25 (following the RS-520 standard), RJ-11 jack, RJ-45 jack, and terminal blocks with strain relief.4.1.1 4-WIRE CONNECTION USING THE DB-25The DB-25 connector on the Model 2085's RS-485 side conforms to the RS-530 interface standard. When connecting to an RS-485 device that also conforms to the RS-530 standard, your cable should be "crossed over" in the manner shown below:MODEL 2085RS-485 (530) DEVICESIGNAL DB-25PIN DB-25PIN SIGNALXMT+ 2...........................3RCV+XMT-14...........................16RCV-RCV+ 3...........................2XMT+RCV-16...........................14XMT-NOTE: It is not necessary that the RS-485 device adhere to the RS-530standard. However, you must make sure that the signals, polarities, and pairingof your connection conform to the above diagram.94.1.2 4-WIRE CONNECTION USING RJ-11 OR RJ-45The RJ-11 and RJ-45 connectors on the Model 2085's RS-485 side are pre-wired for a standard TELCO wiring environment. The signal/pin relationships are shown below:RJ-11SIGNAL RJ-45SIGNAL1...................GND*1.................N/C2...................RCV-2.................GND*3...................XMT+3.................RCV-4...................XMT-4.................XMT+5...................RCV+5.................XMT-6...................GND 6.................RCV+7.................GND8.................N/C*Connection to ground is optionalIn most modular RS-485 applications it is necessary to use a "cross over" cable. The diagram below shows how a cross over cable should be constructed for an environment where both the Model 2085 and the RS-485 device use a 6-wire RJ-11 connector. Similar logic should be followed when using RJ-45 connectors or a combination of the two.MODEL 2085RS-485 DEVICE SIGNAL PIN#PIN#RS-422SIGNAL GND †1-------------------N/C RCV-2-------------------4XMT-XMT+3-------------------5RCV+XMT-4-------------------2RCV-RCV+5-------------------3XMT+GND †6-------------------N/C106. If there is a shield around the telephone cable, it may beconnected to "G" on the terminal block. We recommend connecting the shield at the computer end only to avoid ground loops. A ground wire is not necessary for proper operation of the Model 2085.7. When you finish connecting the wires to the terminal block, the assembly should resemble the diagram below:8. Place the 2 halves of the strain relief assembly on either side of the telephone wire and press together very lightly. Slide the assembly so that it is about 2 inches from the terminal posts and press together firmly. If your cable diameter is too small or too large for our strain relief, please contact our technical support. We have strain relief assemblies to accommodate most cable diameters.(continued)122085SIGNAL RS-485SIGNALXMT+....................................+XMT-.....................................-The above wiring pattern applies regardless of whether you are making the RS-485 connection via DB-25, RJ-11, RJ-45 or terminal blocks. For specific wiring instructions, please refer to the previous pages of Section 4.4.2 WIRING FOR MULTIPOINT CIRCUITSThe Model 2085 supports multi-point applications using either a star or daisy chain topology. Both topologies require special wiring, as well as specific DIP switch settings for master and slave units. Note: Refer to Section 3.2.2 for multipoint DIP switch settings.4.2.1 STAR TOPOLOGYUsing a star topology, you may connect several Model 2085s together in a master/slave arrangement. Maximum distance between the units will vary based upon the number of drops, data rate, wire gauge, etc. Call Technical Support for specific distance estimates.Figure 7 (below) shows how to wire the two-pair cables properly for a Model 2085 star topology. Note that the ground connection is not needed.14APPENDIX APATTON MODEL 2085 SPECIFICATIONS TransmissionFormat:AsynchronousData Rate:Up to 115,200 bpsRange:Up to 9 milesRS-232 Interface:DB-25, male or female (DCE/DTEswitchable)RS-485 InterfaceOptions:DB-25, male or female; RJ-11 or RJ-45 jack;terminal block with strain reliefTransmit Line:2, 4 wire unconditioned twisted pair Transmit Mode: 4-wire, full or half duplex; 2-wire half duplex Control Signals:DSR turns “ON” immediately after theterminal raises DTR; DCD turns “ON” afterrecognizing the receive signal from the line;CTS turns “ON” after the terminal raisesRTS.RTS/CTS Delay:8 mSec or “no delay”Carrier:The carrier is switch selected eithercontinuous operation or switched operation,controlled by RTSSurge Protection: 600W power dissipation at 1 mSPower:Draws operating power from RS-232 dataand control signals; no AC power orbatteries required.Temperature: 0 to 50°CHumidity: 5 to 95%, non-condensingSize: 2.66” x 2.10” x 0.73”16APPENDIX BPATTON MODEL 2085 RS-232 PIN CONFIGURATIONSCopyright ©Patton Electronics Company17Dear Valued Customer,Thank you for purchasing Patton Electronics products!

Unfortunately, the bipolar devices draw a large amount of supply current, which is unacceptable for the numerous applications that require low power consumption. The LTC485 is the first CMOS RS485/RS422 transceiver which features ultralow power consumption without sacrificing ESD and latchup immunity.The LTC485 uses a proprietary driver output stage, which allows a common-mode range that extends beyond the power supplies while virtually eliminating latchup and providing excellent ESD protection. Figure 9 shows the LTC485 output stage while Figure 10 shows a conventional CMOS output stage.When the conventional CMOS output stage of Figure 10 enters a high impedance state, both the P-channel (P1) and the N-channel (N1) are turned off. If the output is then driven above V CC or below ground, the P + /N-wellFigure 9. LTC485 Output Stage diode (D1) or the N + /P-substrate diode (D2) respectively will turn on and clamp the output to the supply. Thus, the output stage is no longer in a high impedance state and is not able to meet the RS485 common mode range requirement. In addition, the large amount of current flowing through either diode will induce the well known CMOS latchup condition, which could destroy the device.The LTC485 output stage of Figure 9 eliminates these problems by adding two Schottky diodes, SD3 and SD4. The Schottky diodes are fabricated by a proprietary modi-fication to the standard N-well CMOS process. When the output stage is operating normally, the Schottky diodes are forward biased and have a small voltage drop across them. When the output is in the high impedance state and is driven above V CC or below ground, the parasitic diodes D1 or D2 still turn on, but SD3 or SD4 will reverse bias and prevent current from flowing into the N-well or the substrate. Thus, the high impedance state is maintained even with the output voltage beyond the supplies. With no minority carrier current flowing into the N-well or substrate, latchup is virtually eliminated under power-up or power-down conditions.APPLICATIONS INFORMATIONFigure 10. Conventional CMOS Output StageV D1D2V D1D2485 F10APPLICATIONS INFORMATIONThe LTC485 output stage will maintain a high impedance state until the breakdown of the N-channel or P-channel is reached when going positive or negative respectively. The output will be clamped to either V CC or ground by a Zener voltage plus a Schottky diode drop, but this voltage is way beyond the RS485 operating range. This clamp protects the MOS gates from E SD voltages well over 2000V. Because the ESD injected current in the N-well or substrate consists of majority carriers, latchup is prevented by careful layout techniques.Propagation DelayMany digital encoding schemes are dependent upon the difference in the propagation delay times of the driver and the receiver. Using the test circuit of Figure 13, Figures 11 and 12 show the typical LTC485 receiver propagation delay. The receiver delay times are:|t PLH – t PHL| = 9ns Typ, V CC = 5VThe driver skew times are:Skew= 5ns Typ, V CC = 5V10ns Max, V CC = 5V, T A= –40°C to 85°C Figure 11.
