KMSmicro 4.0版使用说明下载地址：http://download.hdd.tomsk.ru/download/fpnlsjub?792d7d294b1f44ae44dc82212632e89b版本更新太快了，TMD比3.11版没有什么大的改进：1、启动本地服务器时自动检测并自动充电，已达到所需要的最低激活次数（貌似3.11版就有了，这个版本修复了一些Bugs？）；2、俄文和英文服务器都有，可以根据自己爱好选择（谁没事选俄文干什么，英文还没学好呢）；3、服务器启动时自动同步网络时间（不知道还设置“T”命令干什么？搞不懂这些俄国人）；4、第一步启动服务器建议系统安装完毕后，将系统置于“管理员模式”下进行，办法网上一大堆。

在KMSmicro 4.0文件夹中，双击上述图中程序以启动服务器，不要动其它三个了，没大用。

等待。

貌似有假死的现象，不要管，死等。

可能出现防火墙警告，选择允许通过。

服务器正在启动，并进行自动检测和充电，已达到激活Windows所需要的24次，激活Office 2010和2013所需要的4次的要求。

为保险起见，还是在“Select Option:”处键入“T”以同步网络时间。

直到窗口最下方出现“Press any key to continue”时，表明第一步（启动服务器），也是最重要的一步大功告成。

注意：1、不要关闭此窗口，因为它是激活平台！！！2、鼠标进入窗口，只需在窗口内任意位置双击即可，而要鼠标从窗口释放，则需要同时按下键盘上的CTRL和Alt键。

第二部激活操作系统和3.12版一样，没有任何改变。

在KMSmicro 4.0的文件夹中，选择不同版本的激活器，并以管理员方式运行。

即会出现下属窗口。

点击所需要激活的系统按钮，窗口左上角即会出现红色“processing”（正在处理）字样，稍等片刻，窗口下部即会出现“Activation successful”（激活成功）字样，表明系统已经成功激活180天（够用了吧？以后肯定有永久激活器出现）这时如果需要激活Office的话，上述两个程序都不要关闭，即刻安装Office，再在激活程序中选择所需要激活的Office版本，同样的一会即会显示激活成功的字样。

IRC 聊天工具（xchat,chatzilla,pidgin）入门教程IRC，是常用于linux系统下，使用非常广泛的，古董级别的一种聊天工具，它支持普通的文本聊天，还有文件传输功能。

既然是聊天用的，自然要有客户端软件了。

这次的教程，分别讲述了3种客户端软件的使用，包括：xchat（主要介绍和推荐），Pidgin和Firefox浏览器的一个IRC插件”chatzilla“。

一. xchat客户端软件的安装：安装方法非常简单了，在终端里面输入：sudo apt-get install xchat回车就行了。

安装后，我们退出终端，从“应用程序”—“Internet”，里面可以找到xchat，点击运行吧二. 配置xchat第一次使用xchat，我们需要简单的配置一下，让它更加好用。

看图吧，我挨个解释。

1. 用户信息。

昵称，就是你在IRC聊天里面，用到的名字（不能是中文！！）。

这个名字不是固定的，（这个和QQ一样），你随时可以更改，在这里，你可以先取一个名字。

注意：在IRC世界里，昵称是不能重复的，因此，如果你现在取的名字，已经有人取了，IRC软件，就会自动使用“第二选择”，如果第二个还有人用，就继续往后。

用户名和真实姓名，自己看着办了，写不写都行2. 网络在全世界，有很多“IRC服务器”，就是专门用来提供IRC聊天功能的地方。

目前比较不错的服务器，是叫：Freenode，一会儿我们就先选择这个。

因为，IRC服务器都是“通用”的，只要选择一个就可以。

所以，我建议大家选择了一个服务器后，勾选：启动时不打开网络列表。

因为它已经没用了。

3. 进一步的设置。

我们选择好自己的服务器，比如Freenode，我们点击：编辑。

进入下面的设置这里，我们需要做的是：让IRC软件启动的时候，自动进入“channels”。

我来解释下channel，英文意思是：频道，大家可以理解成是房间的意思。

IRC其实就是提供“聊天室”。

我们在图里面的“favorite channels”后面，可以填写具体的“频道地址”，这个地址，是别人提供给你的。

M7 MIMIC Mode By John Sonnenberg Raveon Technologies Corporation OverviewA MIMIC mode allows two or more M7s to mimic each other ’s digital I/O. The M7 radio must have software version C13 or higher to work in the MIMIC mode. When in the MIMIC mode, the M7 will periodically transmit its digital status. The M7 will also continue to operate as a radio modem, sending/receiving data using pins 2&3 of the DB9, but the other I/O pins of the DB9 will be used for digital input/output.Normally, the Serial I/O connector operates like an RS232 serial interface. If the MIMIC mode is enabled, the operation of the radio is modified to transmit the digital status of the INPUT0 and INPUT1 pins across the radio link, and output their status on the OUT0 and OUT1 pins. There are two aspects to the MIMIC mode:1. The transmitter that sends the status of its digital inputs. This is enabled with the MIMIC X Ycommand. 2. The unit that receives the over-the-air MIMIC message, and sets its digital outputs to match the inputs of the sending station. This function is enabled with the ATIO 1command. ATIO 1 configures the DB9 serial port to operate with RS232 signal levels, and use the digital control lines for digital I/O instead of RS232 flow control. ATIO 0 turns off MIMIC reception ability, and the digital I/O pins will operate as flow control signals.The goal of the MIMIC mode is quite simple: Flip a switch at one location, and have something at another location turn on or off.Technical BriefAN161 Rev A2DB9 Connector Pin-OutThe RS232 9-pin serial I/O connector on the M7 radio is a female 9-pin D-subminiature connector having the following pins configuration. It is pinned out so that it may be plugged-pin COM port.directly into a computer or a PC’s 9Note: RS-232 signals use positive and negative voltages to represent digital 1s and 0s. A positive voltage is a 0, and a negative voltage is a digital 1.The Raveon M7 data radio modem uses a special RS232 driver/receiver IC chip to condition and protect all of the data pins on the DB9 RS232 port. The chip used is an ICL3238. Refer to the datasheet on this chip for information about its capabilities, voltages, and thresholds. Its data sheet is available here: /products/deviceinfo.asp?pn=ICL3238. Configuring an M7 for MIMIC modeMIMIC transmissions are enabled with the MIMIC X Y command. MIMIC 0 disables MIMIC mode and puts the unit in standard radio modem operation mode. MIMIC X Y with X and Y being any positive number will enable the MIMIC feature. The MIMIC X Y command sets the unit to transmit a MIMIC over-the-air message every X seconds when INPUT0 is low, and to every Y seconds when INPUT0 is high.MIMIC Command settingsIf digital input INPUT0 is low, every X seconds, the M7 will automatically transmit the digital status of both the the INPUT0 and INPUT1 pins. If INPUT0 is high, every Y seconds, the M7 will automatically transmit the digital status of the INPUT0 and INPUT1 pins. For example, MIMIC 2 60 configures the radio to send the state of INPUT0 and INPUT1 pins every 2 seconds if INPUT0 is low, and every minute if INPUT0 is high.Radio addressing operates as it does in the standard mode. When a unit receives a MIMIC transmission intended for its ID, it will set its OUT0 and OUT1 pins as determined by the sending stations INPUT 0 and INPUT1.When the unit is in the Command mode, MIIC transmissions will not take place. The command mode is entered by sending +++ into the serial port. See the M7 Technical Manual for information on how to configure the M7 using the built-in commands.The MIMIC transmissions are the same over-the-air format as a standard data transmission from an M7 radio modem, except they contain no user-data, only digital I/O information. AnM7 radio modem configured as a repeater will repeat the MIMIC messages.Failsafe SettingsTo ensure failsafe operation, a FAILSAFE A B command sets the minimum message interval, and the default digital output state if an over-the-air MIMIC message is not received within the failsafe period. A is the minimum period, and B is the ASCII hex value of the digital outputs if the failsafe interval passes and no MIMIC messages are receive. B is also the power-on default value of the digital outputs.For example, FAILSAFE 60 1 configures the unit to require a MIMIC message at least every minute. If one is not received within 60 seconds, OUT0 will go high (open drain), and OUT1 will go low (below ground).It is recommended that the A value for the FAILSAFE command be about 2.5 times longer than the largest of the X and Y values of the MIMIC command. This allows for one MIMIC message to be missed. For example if MIMIC transmissions are set to MIMIC 2 60, a reasonable FAILSAFE A B setting would be a value of 150 for A. This will allow one MIMIC message to be missed and the FAILSAFE value not kick in. If more than two MIMIC messages did not get received, after 150 seconds, the M7 would revert to the failsafe values.To disable failsafe operation, issue the FAILSAFE 0 command. This disables failsafe operation. In this case, the outputs will stay latched at the last condition that was received over the air. The power-on condition of the OUT0 and OUT1 are indeterminate.You will need to set the MIMIC and FAILSAFE values to match the needs of your system. Configuring A One-Way MIMIC LinkTo setup a MIMIC radio link from one point to another, follow these steps:On the transmitting M71. Connect a terminal to the M7, and put it into the command mode (+++).2. Enter the command MIMIC X Y where X is the transmission rate when INPUT0 is low,and Y is the transmission rate when INPUT0 is high.3. Exit the command mode. The M7 will begin automatically transmitting every X/Yseconds.On the Receiving M71. Connect a terminal to the M7, and put it into the command mode (+++).2. Enter the ATIO 1 command. This tells the M7 to reconfigure its serial IO port to allowthe digital outputs to be controlled via over-the-air messages.3. Enter the FAILSAFE A B command. The A parameter will be the maximum amount oftime that should ever pass without receiving a MIMIC message. The B parameter is the digital output state if the time set by A passes and no MIMIC messages are received.4. Exit the command mode. The unit is ready to receive MIMIC messages from thetransmitting station.Wiring a MIMIC LinkTo wire an M7 with a switch that will be “MIMICed”, follow the diagram below:When switch S1 is closed, the M7 will transmit at the X rate, and when it is open, it will transmit at the Y rate. INPUT0 uses RS232 level, and a connection to ground is considered a “low”. Anopen circuit or any voltage above about 1V is considered a high. R1 is shown to ensure that the input goes high when S1 opens. A DPDT switch could be used instead.To wire an M7 to receive MIMIC digital signals, follow the diagram below:When a MIMIC signal is received over the air, OUT0 will follow INPUT0 on the sending station. OUT1 will follow INPUT1. This will cause the 12V lamp to light, or the relay to close if a relay is used. Do not load the OUT0 with a device that will draw more than 100mA. NEVER connect OUT0 to a power source.Optional MOSFET DriverThe M7 radio modem has an optional MOSFET output driver on the OUT0 output. (Only the OUT0,, not the OUT1 output). If this option is installed, OUT0 will be pulled to ground to energize an external relay or lamp whenever OUT0 was supposed to go low. So closing S1 on the sending station will cause OUT0 to go low, energizing the relay/lamp/led…The MOSFET that drives OUT0 is a 2N7002 type device. Do not connect a lamp/relay that draws more than 100mA to OUT0. Also, if OUT0 is driving an inductive load, use a surge-protection diode such as a 1N4001 across the load to prevent high-voltage transients.If the optional MOSFET driver is not installed, OUT0 will simply follow INPUT0 with RS232 signal levels.Two-Way MIMIC using Master-SlaveIn the Master-Slave configuration, one “Master” unit transmits is MIMIC digital data to a Slave unit. This configuration is ideal for point-to-point two-way MIMIC ing.Remember to configure the addressing (ATDT, ATMY, and ATMK parameters), so that the M7 radio modems communicate to the units with the correct IDs. See the M7 Technical Manual for information about addressing and IDs.The Slave is configured to respond with an ACK packet each time it receives an over-the-air message from the Master, and embedded in the ACK packet is the digital status of the Slave. The ATRB command configures the ability to send ACK packets. When the Master receives the ACK packet back from the Slave, it updates its output pins OUT0 and OUT1 to match the values of the Slave INPUT0 and INPUT1.Configure the ”Master” as follows1. Set ATRB 1 to configure the M7 to send messages that will require an ACK back fromthe Slave. By default ATRB is 0 (no ACK transmissions).2. Configure the MIMIC X Y command where X is the transmission rate when INPUT0 islow, and Y is the transmission rate when INPUT0 is high. These are the rates at which the master will transmit.3. Set the FAILSAFE A B parameter. The A parameter will be the maximum amount oftime that should ever pass without the Master receiving a MIMIC message from theSlave. The B parameter is the digital output state if the time set by A passes and noMIMIC messages are received.4. Execute the ATIO 1 command. This tells the Master M7 to reconfigure its serial IO portto allow the digital outputs to be controlled via over-the-air messages.On the “Slave” M7, as follows:1. Set ATAK 1 to enable the Slave unit to send ACK packets back to the Master wheneverit receives a message from the Master. Embedded in these ACK packets are theSlave’s digital I/O status bits.2. Execute the ATIO 1 command. This tells the Slave M7 to reconfigure its serial IO portto allow the digital outputs to be controlled via over-the-air messages from the Master.3. Set the MIMIC X Y parameters to something very long. The Slave will respond totransmissions from the Master, so the X Y settings should not be set too short.MIMIC 120 120 will tell the Slave to send its input status every 2 minutes. But it will only send its I/O status automatically if the Master has not sent MIMIC data to it, causing the Slave to send and ACK and the I/O status. If the Master fails to send, then this X Ysetting will determine how often the Slave transmits.4. Set the FAILSAFE A B parameter. The A parameter will be the maximum amount oftime that should ever pass without the Master receiving a MIMIC message from theSlave. The B parameter is the digital output state if the time set by A passes and noMIMIC messages are received.Autonomous Two-Way MIMICWhen configured for autonomous MIMIC transmissions, all M7 radios will transmit the digitalI/O status at the preset intervals as configured with the MIMIC X Y command. When operating in a multi-point configuration, this type of setup is probably preferable to the Master-Slave configuration described above.Remember to configure the addressing (ATDT, ATMY, and ATMK parameters) of all M7 radios, so that the M7 radio modems communicates to the units with the correct IDs. See the M7 Technical Manual for information about addressing and IDs.Configure the M7 radio mode as follows1. Configure the MIMIC X Y command where X is the transmission rate when INPUT0is low, and Y is the transmission rate when INPUT0 is high. These are the rates atwhich the master will transmit at. In systems with many radios, you should consider setting X and Y to different values for each radio.2. Set the FAILSAFE A B parameter. The A parameter will be the maximum amountof time that should ever pass without the Master receiving a MIMIC message from the Slave. The B parameter is the digital output state if the time set by A passes and no MIMIC messages are received.3. Execute the ATIO 1 command. This tells the Master M7 to reconfigure its serial IOport to allow the digital outputs to be controlled via over-the-air messages.4. You may want to enable “Busy Channel Defer”. Set ATBC 1 to enable Busy ChannelDefer. When ATBC is set to 1, the M7 radio will check to make sure the radiochannel is not busy before it transmits, and if it is, it will defer until the channel is clear. If ATBC is set to 0, then this feature is off, and the M7 will transmit when it needs to transmit, regardless of the channel status. By default, ATBC is 0 (unit does not defer to other radios on the channel).Raveon Technologies Corporation2320 Cousteau CourtVista, CA 92081********************760-444-5995。
