艾维通 BB-USOPTL4-2P 4P 4 通道 RS-232 转以太网转换器 使用手册说明书
IntroductionIndustrial and commercial measurement and control systems often have stand-alone devices with unused serial ports. Advantech BB-ESRx Serial Servers allow you to connect those ports to your existing LAN or WAN, giving you access to more information and the ability to configure, manage and troubleshoot those devices from a control room, office or distant location via a WAN. Save the cost, time and trouble of carrying a laptop out to devices located in distant, dirty or uncomfortable environments.BB-ESRx Serial Servers are built for industrial environments, featuring an IP30, slim line, DIN rail mountable case. They operate from a range of voltages using AC or DC power, feature terminal block power connectors and even support redundant DC power. An external power source is required (not included, sold separately).Connect a serial device to the BB-ESRx serial port and connect the BB-ESRx to your LAN. Your networked computer ‘sees’ the device over the network as a virtual serial connection. BB-ESRx serial servers support TCP or UDP protocols and allow Transmit-to and Receive-from multiple IP addresses. There are four methods of configuration: Vlinx Management Software, Web Server, Telnet, or a direct RS-232 console connection using a terminal program.Operation(For more information, see user manual on CD.)Vlinx™ Manager software allows easy access to the serial server to configure the server and its ports, upgrade firmware and monitor port status and activity. When the Vlinx Manager opens, it searches for and displays all serial servers on the network. The Monitor Port feature allows you to use any PC on the LAN/WAN to actively view and troubleshoot communications status. It shows when there is a client connectionto the server and the client IP address. It displays the number of bytes transmitted and received, as well as the status of the hardware handshaking lines.BB-ESRx serial servers can be accessed and configured from any web browser (ie, Internet Explorer) on the LAN/WAN allowing you to remotely manage the software and your serial device and do off-site troubleshooting.Vlinx Serial Servers provide automatic resumption of the TCP data connection in caseof a power failure or loss of an Ethernet connection on either the client or server. Once the Heartbeat connection is established, the server sends a signal to the client every five seconds until communication is re-established. Without this feature, a device that loses a connection and stops communicating would not be able to reconnect without a person physically attending to the problem. The Heartbeat feature works with virtual COM and TCP direct IP connections.• Ethernet enable 1, 2 or 4 serial ports• Data rate: 110 to 230.4 kbps• Wide operating temperature range: -10 to +80 °C• IP30 DIN rail mount case• RS-232/422/485 full-duplex and half-duplex• Auto detects 10/100 Mbps Ethernet• External power source required (not included, sold separately)FeaturesAccessories – Sold SeparatelyBB-MDR-40-12 – Power Supply, 12 Vdc, 40 W, 3.33 A, DIN rail mount, plastic BB-ESR904BB-ESR901 BB-ESR902 BB-ESR904。

Click the button “Read” to read out the configuration data on the computer.6 Configuring with the programming assistant6 Configuring with the programming assistant 6.2 Configuring via USB stickThe USB stick can contain one global file or any number of individual configu-ration files. Any counter can be programmed with a global configuration file, whereas single files can only be used for the counter with the matching serial number. The files must be stored in the “VersaCount XP” folder on the stick.If the USB stick is inserted or if the voltage is turned on when the USB stick is inserted, the counter automatically starts configuring and looks for configura-tion files. The display first shows: USB search, followed by USB Single or USB Global. Single or Global are displayed for about 10s. If E is pressed on the key-board during this period, the new configuration file is read and saved. The dis-play then shows USB Config followed by USB done.If E is not pressed within 10s, the configuration is aborted, the previous config-uration remains active and the display shows USB abort.6.3 Text messagesDescription of the text messages generated by the USB interface on the counter.USB SEArCH Searching driveOnce a USB drive is inserted, it is checked for the existence of the “VersaCount XP“ directory and the configuration file(s) in the directory.• Global file: T_000000.CFG (irrespective of serial number)• Single file: T_003231.CFG (only for use with the counter bearing serial number 3231)USB no dir No directory foundThe interface has not found a directory called …VersaCount XP“.

The process is aborted and a restart prevented since no configuration has taken place. The display returns to stan-dard view after a couple of seconds.176 Configuring with the programming assistantrESEt E2Error 2: Drive was removed during the configuration pro-cessThe USB drive was removed during configuration. The process is aborted. The counter must be restarted to reset any possible errors in the configuration. This is shown by the message “rE-SEt” on the display. Press any key on the counter to restart it. In order to reconfigure the counter, remove the USB drive and insert again.rESEt E3 XXX Error 3: A configuration command has produced an error messageA command error has occurred during configuration of the counter, i.e., one of the commands in the configuration file re-ported an error. The digits shown here as XXX (e.g., 014) refer to the command error in the configuration file. It represents the sequential number of the executed commands, not the row number. Example: If error “14” is displayed, the error is con-tained in the 14th command in the configuration file, irrespec-tive of how many comments are noted.USB Abort Configuration has been abortedThis message appears in the display if the configuration pro-cess is not started within the specified time after finding the configuration file, or if the process is manually aborted. The display returns to standard view after a couple of seconds.187 Communication interface 7 Communication interface7.1 Definition of the communication interfaceGeneric Interface for VersaCount 77xGeneral:Explanation of the term “Generic Interface”The generic interface provides basic functions for reading/writing counter values and function settings to/from the counter. An ASCII protocol is used for communication, but other, higher protocols can be set. This documentation describes the functionality of the generic interface between the counter and the interface PCB.Following is only an overview of the generic interface. For detailed view, please visit our webpage .Hardware protocol:The generic interface is based on RS232.Baud rate: 38.4 kBdBits: 8Parity: evenStop bits: 1Software protocol:The generic interface between VersaCount 77x and the interface PCB is based on ASCII commands and data values in ASCII format.The internal counter structure of the values is binary and optimized for high counting speeds. The values exchanged via the generic interface are ASCII values. The counter converts the values into its internal format.197 Communication interface7.2 Overview of generic interface functions:Basic functions:1. Read / write the basic counter functions2.

The command ends with CR (0Dh). (0Dh)C MD R CRThe counter responds by repeating the command name and indicates the return value, separated by a space. The response ends with CRC M D-123456CR Unknown (incorrect) commands generate the following response:E R R CRSyntax for write commands:The commands are comprised of the command name (3 characters) followed by a space and the code for write (“W”) and the value to be written, which con-sists of up to 6 digits and the algebraic sign. The command ends with CR (0Dh).C MD W-123456CRThe counter responds by repeating the name of the command, followed by “OK” if the command has been executed or “ER” if the command could not be executed, e.g., because of an invalid value. The response ends with CR. Command has been executed:C MD O K CR237 Communication interfaceCommand error:C MDE R CRSyntax for function commands:Function commands are commands for calling up functions within the counter, without reading or writing values.C MD CRResponse:Command has been executed:C MD O K CRCommand error:C MDE R CR7.5 Sequence for setting and alteringSequence for setting valuesSome values / settings can be transferred whenever you like, others require adherence to a specific sequence.1. If the basic function of the counter is altered, the default values assignedto the basic function are automatically loaded. As such, function codes must always be changed after altering the basic function. Otherwise the counter will overwrite the changes made to the function codes.2. All counting values are automatically deleted if the prescaler is altered. So changes to the prescaler must always be made before altering the counting values.247 Communication interface 3. Initially, all values are altered only in the working memory. Once the values have been transferred, they must be saved to the EEPROM using the STV com-mand. Changes to function codes do not become effective until the counter has been restarted/reset (“RST”).The following sequence should be adhered to when changing values:- Set basic function (BFN)- Set default values (F00)- Set function codes (F01 (35)- Save values to EEPROM (STV)- Reset/restart counter to activate the changes (RST)- Set the prescaler (PSC)- Set the preselect values (PR0 .. PR2)- Set the counting values (CNT, TOT, SU1, SU2)- Save all values to EEPROM (STV)Any function not mentioned here does not have to adhere to a specific sequence. All read functions can be used at any time.258 Technical data8 Technical dataThese operating instructions only contain the supplementary technical data for the interfaces.

电脑USB转TTL串口RS232串口模块
电脑USB转TTL串口/RS232串口模块对于一些学校、工业、科研客户来说，电脑的串口非常重要，很多设备都必须采用串口和电脑端软件连接，很多电路模块可以非常直观方便地利用串口调试软件进行调试，很多仪器必须通过串口进行通讯和数据交换。
但是目前笔记本电脑因为空间的限制和其他方面考虑的原因都没有串口，甚至一些台式电脑也取消了串口配置，这让我们迫切需要串口的客户非常苦恼。
USB转串口模块全称为USB to Serial port Module，它可以将USB接口虚拟成一个串口，解决客户无串口的苦恼。
现在市面上的USB转串品的设备可谓是琳琅满目，质量也是参差不齐。
造成这种现象的根本原因就在于控制芯片的不同。
现在USB转串口桥接芯片有很多，比如CP2102、FT232、PL2303等等。
但并非每一种芯片都可以用作ISP下载。
经过测试CP2102是不能下载的，而FT232可以下载，但其价格实在不菲。
最为适中的就是台湾生产的PL2303，可以稳定下载，并可以支持多种操作系统。
PL2303HX采用28脚贴片SOIC封装，工作频率为12MHZ，符合USB 1.1通信协议，可以直接将USB信号转换成串口信号，波特率从75～1228800，有22种波特率可以选择，并支持5、6、7、8、16共5种数据比特位，是一款相当不错的USB转串口芯片。
产品1：采用PL2303芯片的USB转TTL串口模块每个12元含一根4芯杜邦连接线这是我们用PL2303芯片开发的USB转串口模块，采用机器自动焊接都经人工检测，电路板只有30*16*7毫米，模块一共引出5根脚，引脚电平为TTL，引脚定义如下：+5V、P3.0 TXD 、P3.1 RXD 、GND 地线、＋3.3V 。
其中＋5V和＋3.3V电源输出线一般情况下都不用的，不需要连接。
现在购买PL2303模块我们还赠送一根30厘米长的杜邦连接线，它一头是四位一体的插座可以直接插到我们的2303模块上，另一头是四个独立的杜邦头，可以灵活插到设备上，非常方便。

设备内部采用9v的电池供电，也可采用外部直流9v电源。
采用db9孔通用串行接口。
二、指示灯含义前面板如图所示：测试仪分LED灯指示、4位数码管显示及四个操作键三个部分。
其中各灯的使用含义如下：RUN 灯：绿色，长亮表示设备系统运行中。
RXD灯：黄色，闪烁表明有数据接收。
TXD灯：黄色，闪烁表明有数据发送。
DTR 灯：黄色，亮时表示数据终端准备好。
DSR 灯：黄色，亮时表示数据装置就绪。
OK灯：绿色，模式1长亮表明接收数据正确，如果发生闪烁则表明数据接收中有错误发生。
如果不亮，表明线路发生断路或者对端设备未将数据环回；模式2时有数据接收并且此灯亮，表明已成功将收到的数据发送出去，没有数据接收时此灯为暗；模式3~11时长亮表明在此速率下与对端设备通信正常，此时右侧数码管显示数值为被测设备工作速率。
四个数码管显示分如下两种：（1）模式1~11（b）时只显示三个数码管，最左侧数码管显示为模式值，表示端口测试仪的当前工作模式，显示值用16进制表示，范围从1到b（”1~9”表示模式1至9，字母”A”表明模式10，字母“b”表示模式11）；右侧两个数码管显示串口工作速率信息，模式一和二波特率固定值为9.6，即工作速率为9600bps。
3~11模式下默认值为9.6，此时，让本测试仪自动循环或按+1或-1键都可以改变其波特率值，如果未与对端设备建立有效通讯，则OK灯不亮，同时一定时间间隔后速率将变为19200（显示19），如果仍未建立有效通讯则间隔一定时间后再变为1200（显示1.2），如此自动循环，右边数码管显示值依次为…9.6—19—1.2—2.4—4.8—9.6…；自动变化的同时可以按+1键对其进行操作，如显示9.6时按+1键则显示变为19，即速率从9600变为了19200bps，再按一次为1.2，如此下去依次显示9.6—19—1.2—2.4—4.8—9.6…；同理按-1键则可依次显示9.6—4.8—2.4—1.2—19—9.6…，其中1.2代表1200bps，2.4代表2400bps，4.8代表4800bps，9.6代表9600bps，19代表19200 bps。

• 允许发送（Clear to send-CTS）——用来表示DCE准备 好接收DTE发来的数据，是对请求发送信号RTS的响应 信号。当MODEM已准备好接收终端传来的数据，并向 前发送时，使该信号有效，通知终端开始沿发送数据 线TxD发送数据。
并行接口
• 目前，计算机中的并行接口主要作为打印机端口，接口使用的不再是36 针接头而是25针D形接头。所谓“并行”，是指8位数据同时通过并行线 进行传送，这样数据传送速度大大提高，但并行传送的线路长度受到限 制，因为长度增加，干扰就会增加，容易出错。 • 现在有五种常见的并口：4位、8位、半8位、EPP和ECP，大多数PC机配 有4位或8位的并口，许多利用Intel386芯片组的便携机配有EPP口，支持 全部IEEE1284并口规格的计算机配有ECP并口。
