卫星接收器调试说明卫星电视接收器知识(1)(2008-12-06 22:26:42)转载分类：卫星电视知识标签：杂谈卫星电视接收器知识2008-02-12 21:49【第一章：学习基础知识】一、您可能刚刚接触卫星电视这个东西，魔大的诱惑力吸引着您，是不是苦于自己知识有限，该买什么机器呢？怎么安装呢？身边又没有懂的朋友，找谁去问呢？况且具体问题一句话、两句话也说不清楚。
自己上网去查吧，茫茫网络，我到哪里去寻找，知识太多了，从什么地方开始学起，遇到难题，网上又没有网友给你解答时，自己苦苦寻觅，一熬就是半夜。
这种经历，我想网友们都经历过。
虽然我自己懂的东西也不多，还有很多东西没有研究过，比如自己写卡，模块机使用，以及更新机器系统等，今后会认真学习补充自己。
但是我还是抽出了一段时间写了这篇文章，为没有接触过卫星的朋友简单介绍下，让您早日拥有自己的器材，早日看到精彩的节目。
文章介绍本人在卫星电视接收过程中的经验教训，并普及一些卫星电视接收的知识。
此外，转载和介绍一些实用的文摘、器材制作，为广大卫视爱好者服务。
二、要想看卫星电视，应该具备这些硬件：（1）接收机现在基本上都是数字的了。
种类很多，牌子也不少，但分类我想也就4种A、免费机器（只能收免费节目，锁码频道收不到）B、插卡数字机（配合卡，可以收看锁码频道）C、接收卡（需要电脑支持，用软件解部分锁码频道）D、模块机（价格稍贵，需要模块和卡）（2）天线天线尺寸大小不等，又有正馈、偏馈之分。
不同星上的节目由于卫星位置和功率选用不同的天线尺寸和种类。
（3）高频头牌子也很多，有配合正馈使用的C头，和偏馈使用的KU头。
（4）馈线就是咱们无论看有线电视或者收无线电视信号用的75-5同轴电缆，当地都可以买到，这个东西质量可很重要，一般天线和接收机的距离不要超过50米，否则信号就会衰减拉，如果馈线太差的话，我想30米就不成了。
所以一定要选择质量好的。
（5）F头馈线与高频头、馈线与接收机连接部分所用，一般你买机器经销商都免费提供的。

卫星电视接收调试方法及接收参数将天线同轴电缆室内一端英制连接头连接到卫星接收机“天线输入” 连接口上，用随机携带的音／视频线将接收机的“视频”和“左／右音 频”输出端分别与电视机的“视频”和“左／右音频”输入端相连，将电源 线与 220 V／50 Hz 交流电相连后打开接收机电源开关。
带网络接口的卫星电视／数据接收机(RJ-45 接口)，还要将网线接 到计算机网卡接口上或交换机上(注：将卫星接收机的配置程序安装 在计算机上，由计算机完成参数配置)。
卫星电视接收机按功能分为两类：一是普通电视接收机；二是电视 ／数据接收一体机。
它们的安装与调试方法分别如下：1．普通电视接收机的安装与调试 (1)连接信号线。
第一，连接卫星信号输入：首先检查“射频输入” 连接头是否完好，将同轴电缆线接头接到机器“射频输入”端。
第二， 连接 s 视频端子：用 s 视频线将本机的 s 视频输出端与电视机的 s 视 频输入端相连。
第三，连接音、视频信号：用音、视频线将本机的“L ／R”和"VIDEO"分别与电视机的“左／右音频”和“视频”输入端相连。
(2)调试内容和方法。
卫星接收机的调试主要是用遥控器调出配置 “菜单”(MENU)，根据菜单的提示，按卫星传输平台提供的卫星参数 将卫星接收机参数配置好，主要参数包括：①根据所要接收的卫星， 设置好卫星接收机所要接收的卫星信号下行频率(中央平台下行频率 为 12 620 MHz，山东平台下行频率为 12 655MHz)；②设置好本振 频率(具体情况要看高频头标定的本振频率数值，一般为 11 250 MHz或 11 300 MHz)；③设置好下行极化方式(中央平台下行极化方式为 垂直，山东平台下行极化方式为水平)；④设置好符号率(中央平台符 号率为 32 553 Ksps，山东平台符号率为 4 340 Ksps)；⑤设置好纠 错方式(FEC：3／4 或 AUTO)。
各种卫星电视接收机的操作指南1.通过自动搜索功能自动搜索节目以航天珠江WTD-198型卫星接收机为例，其具体操作步骤如下：（1）按遥控器“菜单”键进入“菜单”目录。
（2）在“菜单”目录中选择“系统设置”，按“确认”键。

(1810)Contact details ......................................................18(1) GeneralThe AR8200 is designed to be connected to a computer using the optional CC8200 lead with built-in level shift conversion, this will enable computer control via the RS232 serial port of a computer. An additional piece of software will usually be required in order to address the computer’s serial port with the correct set of parameters. If using an IBM-PC or clone (with 80386 processor or higher)Microsoft Hyper Terminal (or WINDOWS TERMINAL on Windows 3.1x) may be used to address the computer’s serial port.In order to gain the greatest flexibility, a specialist software package is desirable. For this reason a Windows based PC package is supplied FREE on the CD-ROM accompanying the CC8200 (this may also be made available from the AOR web site ).For those wishing to compile their own software (for computers other than the PC etc) or for basic terminal control, please refer to the following command protocol.(2) Supplied AccessoriesPlease check that the following items are included in the package:CC8200 lead with built-in level shift (9-pin D type connector)One CD-ROM containing protocol listing and PC software One(3) Connection for RS232 operationThe option socket is mounted on the right hand side of the cabinet underneath the 12V d.c. input socket. The socket is protected from dust by a grey rubberised case stopper which is hinged toward the front of the cabinet. Gently lift the stopper from the rear edge to reveal the D-shaped metallic socket. Be careful to keep dust and dirt from this socket and to prevent liquid entering the AR8200 via this socket. Ensure that no conductive material is allowed to short circuit the socket which may damage the receiver.&Notes: Switching the receiver On, setting of volume and adjustment of squelch cannot be achieved via the RS232 port.Computers “always” generate RF noise which may interfere with the AR8200 reception if the standard helical rubber aerial is used.To reduce the effects of noise, use of a remote aerial is highly recommended with good quality 50 OHM coaxial cable employed.The following signals are available via the option socket including detector output, mute and AGC. This pin-out assumes connection using the AOR optional OS8200 or CC8200 leads (refer to page 117 of the English language operating manual):-®&Note:TXD + RXD (levels to drive a level shift converter)The voltage output level to drive external RS232 is deliberately below ‘H’ level. If connecting to an external I.C., you must be aware of latch status.Downloaded byAmateur Radio Directory Connect the optional CC8200 computer control lead to the option socket and connect to a computer.The RS232 parameters may be defined using the CONFIG menu. Baud rates (transfer speed) maybe set to 4800, 9600 or 19200bps. It is also possible to set an ‘address’ to facilitate connection of upto 99 AR8200 to a single port for custom operation, the addresses may be set between the limits of01 to 99 with 00 representing single radio operation.When operating from external RS232, the legend ¤ will be displayed on the LCD. Please refer to page109 section 14-6 of the English language operating manual for information on the CONFIG menu settings.If your computer has a 9-pin ‘D’ type connector then simply connect to the computer’s serial port, if however the computer input is 25 way, either a 9-pin male - 25-way female adaptor (ensure all pins are connected through) or patch lead will be required. If a lead is used, the following connections are suggested:-CC8200 9-pin male PC 25 way female233257 GND7485The following RS232 parameters are employed:-Interface Built in level shift within the CC8200 leadConnections used TXD, RXD, GNDFlow control Software X flowBaud rate19200, 9600, 4800 (selectable)Data8 bit, 2 stop bitsParity NoneRS232 command set ASCII text, <CR> or <CR><LF> delimeter&Note: The ñòïðarrow keys and remote IDcommand (^A) are non-printableBoth the computer and AR8200 must use the same parameters for correct operation. If data is regularly lost or corrupted, try using a slower speed such as 4800 baud. Use of a slower baud rate should not greatly reduce overall communications transfer rate since the processing time within the receiver as PLL lock-time ultimately restricts the whole process.&Note: When changing BAUD rate, switch the AR8200 Off/On to ensure the new speed is selected.(4) Use of Microsoft WINDOWS ‘Terminal’ and ‘HyperTerminal’Windows 3.1x uses TERMINAL in a similar way using TERMINAL in the program Manager group. If the terminal program has not been configured an error message will appear (depending upon the serial port / mouse configuration). Click on [OK] to continue. TERMINAL will open and appear on the screen. You may re-size or maximise the screen at this point. Click on the S ettings heading toward the top of the screen so that the communications and terminal parameters may be configured. Click on “TERMINAL EMULATION” then select “ANSI” then click on [OK]. Click on the S ettings heading toward the top of the screen so that the communications and terminal parameters may be re-configured. Click on “TERMINAL PREFERENCES” then select the required options. Finally click on [OK]. Click on the S ettings heading toward the top of the screen so that the communications and terminal parameters may be re-configured. Click on “COMMUNICATIONS” then select the options as required. The choice of COM port (COM1, COM2 etc) will depend upon your computer serial port and mouse configuration. Finally click on [OK]. Click on theF ile heading toward the top of the screen and select SAVE_AS. This will enable the chosen parameters to be saved in a file which may be OPENED next time TERMINAL is selected so that the parameters will not require future re-configuration (.TRM being the default extension). The file is saved in the main WINDOWS sub directory. For further information regarding WINDOWS TERMINAL and configuration, please refer to the operating manual supplied with Microsoft software and the computer. Click on “COMMUNICATIONS” then select the required options. The choice of COM port (COM1, COM2 etc) will depend upon your computer serial port and mouse configuration. Finally click on [OK].Assuming you have Windows98 loaded on an IBM-PC compatible computer (Windows95 setup is virtually identical) click on the START button:Next scroll up through PROGRAMS, ACCESSORIES, COMMUNICATIONS and onto HYPER TERMINAL (click):The following screen will be displayed:Double click the HYPERTRM.EXE icon, the following screen will be displayed (this may take quite a few seconds as Windows checks your hardware:Enter an identifying name, such as AR8200 then click on OK. The CONNECT TO screen will be displayed:Select the required communications port (serial port). By default, Com1 is selected, this is correct for most lap-top computers but Com2 is more usual for a desktop computer (especially when a serial mouse is used on Com1). Click on OK.Input the required communication parameters as shown above (this example shown 9600 baud but you can select 4800 or 19200), whichever has been configured on in the AR8200 receiver... they MUST be the same. Click on OK .Select the ‘PROPERTIES’ icon (finger pointing at a written page), select ‘SETTINGS’ then click on ‘ACSII Setup ’.Click on the fields indicated to add carriage returns to outgoing and incoming text. Echo displays your keyboard strokes input on to the computer screen. If incoming text is double-spaced, remove the tick box for ‘ASCII Receiving’. Click OK .Refer to the command listings later in this section... to try out the link, ensure that the AR8200 is in 2VFO mode (if not type VA [ENTER] ) then type the command RX [ENTER] via the computer keyboard. The AR8200 should respond with the currentfrequency displayed on the AR8200. To change frequency type RF123 [ENTER], the AR8200 should change to 123.000 MHz.Downloaded byAmateur Radio Directory (5) How to send a commandEach command comprises of two upper case letters (header) along with options as required. All commands use ASCII code which MUST BE IN UPPER CASE (except for the ñòïð arrow keys and remote ID command (^A) which are non-printable and use the control codes of ASCII).A multiple command entry is only valid where specified. Where a multiple command entry is allowed, each command MUST be separated with a space “h20” (HEX DECIMAL). Each command is completed with a [CR] or [CR] [LF]. Although there is no local echo, either [CR] or specified response should come back from the receiver after confirming the correct command.If no response has been gained after a short while, the receiver has failed to receive the command properly. Send a [CR] thenre-send the command. Should problems persist, check your connections and try reducing the RS232 baud rate.AR8200 remote indicationWhen the AR8200 has received a command via the RS232C port the receiver’s LCD will display the symbol.
