Savi D300 产品说明书

Savi D300 产品说明书

INTRODUCTIONThe D300 is a decoding unit that allows users to access high quality streams directly from the internet without a PC or classic computer-based connection. Users can connect HDMI and composite AV output devices to the decoder, as well as USB 2.0 transparent peripherals like keyboards and mice, then easily access streams directly from the D300 via any stream’s IP address.TECHNICAL SPECIFICIATIONSHARDWARE INSTALLATION1.Before starting, be sure to have your encoder ready and set up and note the IP address. See theSaviStreamer E300 Encoder manual for how to do this.2.Connect the RJ45 connector on the D300 Decoder to your network with a CAT 5e/6 cable orconnect via WiFi. Please be sure to have all devices within the same network.3.Connect the HDMI connector on the D300 Decoder to a display.4.Optionally, connect a USB keyboard & mouse to the D300.5.Power on the D300 decoder with the provided power adapter.6.Power on the display connected to the D300 Decoder.7.Press the power button on the front and wait a few seconds for the D300 Decoder to initialize.8.When you see the Player status screen on the On Screen Display (OSD), use the supplied IRremote control or a USB keyboard & USB mouse to select Configure in the upper right corner of the screen. (See Figure 1).9.Once Configure is selected, select Source. Enter the IP address for your streaming sourceformatted like the example shown in Figure 2. And select OK.a.Please note that the IP address format usually consists of the following:rtsp://xxx.xxx.x.xxx:8554/where x is the numerical value for the device’s IP address.10.Start the E300 encoder and the video stream. See the SaviStreamer E300 manual for how to dothis.Figure 1 and Figure 2.SaviStreamerGUISaviStreamerGUI is our free software used to connect our D300 Decoder to E300 Encoders for streaming.Getting Started:To ensure proper installation, please:•Use at least Windows XP Professional (w/ Server Pack 2-3), Windows 2003, or Vista operating systems.•Log into your system as system administrator•Turn off Windows Firewall or select SaviStreamer Manager under firewall exceptions tab in control panel.•If you do not wish to turn off firewalls or make an exception for SaviStreamer Manager, please contact SmartAVI’s technical support for alternative processes.Installation:SaviStreamerGUI requires Java version 8 to be installed onto the PC that will be used to manage the software. Once Java is installed, install our SaviStreamerGUI software. SaviStreamerGUI will be split into two different parts: Encoders will display on the left side, and Decoders will display on the right side. Simply select the appropriate Encoder’s bubble to assign the D300 Decoder (refer to Figure 3). Once assigned, double click the name of the D300 Decoder and a new menu will appear. Click on ‘Start Playing’ to begin streaming the video input of the selected E300 Encoder. Please note that once a D300 Decoder has been assigned to an E300 Encoder, further setup will not be needed if the devices are power cycled as it will be saved into memory of the D300 Decoder to automatically reconnect.Figure 3Control Via WebSaviStreamerGUI also comes in a web based version as our G300 Gateway. The G300 Gateway makes it easy to access control over the D300 Decoder over any computer without installing any additional software. Simply enter in the IP address of the G300 Gateway and it will auto detect any D300 Decoder and E300 Encoders. Once on the web click on the tab next to “Encoders/Decoders”, this is the serial number of the D300 Decoder that is detected. A new window will then pop up, select “Decoder” and input the IP address of the E300 Encoder into the source field. Click “Start Playing” and the D300 Decoder will begin streaming.Troubleshooting TipsFactory Reset:To perform a factory reset, please follow the steps below:1.On the splash screen that shows SaviStreamer D300 in the center, navigate to the top rightwhere the “Configure” button is. Select “System”2.This will bring up the Settings page, navigate to “Backup & reset”.3.Select “Factory data reset”4.Select “RESET MBX”5.Select “ERASE EVERYTHING”6.This will begin the factory reset, causing the device to reboot and display the SaviDecoder D300screen a few times. Please note: The screen will flash multiple times and may take a few minutes to complete the reboot. The LCD screen on the front will display “boot” until the processcompletes and the splash screen that shows “SaviStreamer D300” will display again.7.You will now see the Source URL field empty and can be entered again.。

尼康D3000入门贴

尼康D3000入门贴

尼康D3000入门常识贴我习惯用M档:1、根据天气和现场光线设置ISO感光度,感光数值越低越好(按住相机左侧“Fn”键后,用右手拇指拨动“指令拨盘”即可调整感光数值);2、根据现场光线和拍摄意图设定光圈值(按住相机右上方的“曝光补偿”按钮后拨动“指令拨盘”调整光圈数值);3、最后再直接拨动“指令拨盘”调整快门数值即可,快门数值设置时要查看取景器里显示的曝光补偿显示,曝光减0.3至0.7稍好。

新手必读:数码摄影入门速成30招很多时候,人们因为冲动会购买一台数码相机,也因为开始的新鲜猛拍三千张照片,之后,大部分的相机却束之高阁了。

为什么?一个重要的原因是:你没有拍出让人激动、令人欣赏的照片。

你没有好PP 上传于网上,不能让朋友分享,所以没了信心,也因此没了兴趣。

我们不能排除你试图努力过:相机附送的《操作指南》你抽空就会看,你也去多个网站收罗了一大堆专业技术或技巧……但这几乎很少帮到你。

尤其对于希望保持“对准即拍,简单快乐”的体验者而言,那些专业技术或器材要求显然离你们太远了。

永远记住摄影界里有一句格言:一流摄影靠想法,二流摄影靠技术,三流摄影靠器材。

所以千万别为自己仅有一台傻瓜级数码相机而沮丧,那并非你拍不出好PP的借口。

你现在仅仅需要做的是:心态归零。

从避免犯常识性错误开始,(纠正那些你不知道或一直不在意的错误),随即掌握一些“获取视野、对准即拍”的成功经验或经典技巧。

摄影并没有你想像的那么难。

相反,拍出生动有趣或激荡人心的照片,任何人都可以做到。

摄影经验空白不要紧,追求操作简明扼要、快捷易用也不再是奢望,以下的内容正是为你而编的。

好照片是怎么拍成的?按下快门是开始也是结束。

开始总很简单,而结局千差万别。

那些引人入胜的、经久耐看的照片是如何拍出来的?他们有什么共同的成功秘诀?《美国纽约摄影学院教材》给了我们一个答案:那些具有摄影家眼力的作品总是那么经典和引人入胜。

更具体的说,要是你拍的照片达到如下3个标准那么它不经典也算是出色的作品了。

1.面板说明:
面板上方有两个指示灯:从左至右为
1路报警指示灯、2路报警指示灯。

面板上共有四个按键,其它四键从左—右依次为:
Setup、▲、▼、Enter。

Setup键具有参数设定键和退出键两个功能。

参数的增大和减少用▲和▼调整。

Enter键为确认键。

2.D3000压力开关/变送器的设定及标定
设定时所需参数及意义如下:
H:满量程显示值;
L:零点显示值;
BF:报警方式0为不报;1为报警。

报警状态时,B1、B2为上限报警;B3、B4为下限报警。

这样两个双刀双掷继电器
可组成双上、双下、上下等不同的报警方式;
B1:上限报警值;
B2:上限报警值;
B3:下限报警值;
B4:下限报警值;
SH:电流输出的上限调整值;
SL:电流输出的下限调整值;
DF:回差值;
ED:设定值的存密码值。

注:B1、B2报警值对应同一继电器High(上限报警)。

B3、B4报警值对应同一继电器Low(下限报警)。

设定过程如下:

4.外部端子接线定义:
输入电源为85V AC~265V AC交流(24VDC直流)图标为接大地端I+、I-为4~20mA电流输出
H、L分别为微差压传感器的高、低压侧
B为继电器的常闭端、G为继电器的公共端、K为继电器的常开端其中High 是上限报警,Low为下限报警。

端子按线定义:(见图3)
