局域网故障 - 红色X. [英] LAN Trouble -- Red X
问题描述
我正在尝试在朋友的XP上安装相机软件。实际上，相机在房子外面，并且有一个 中间盒通过以太网电缆（交叉）连接到PC。相机插在盒子里。我非常有信心我们
拥有合适的TCP / IP地址。
如果我进入控制面板，我会看到 两个网络图标：LAN和RealTek8139。他真的没有局域网。我猜测realtek端口是PC上的以太网端口。
以下是 关于连接的用户手册中的评论：
===========
将Video Sentinel框连接到PC网络接口卡（NIC）。
如果您通过一个
集线器将Video Sentinel盒连接到计算机，则标准以太网电缆应该足够（10 / 100Base-T）。 但是，如果您希望直接从中
PC连接到Video Sentinel盒，则应使用交叉以太网电缆。
两种电缆类型都可以在办公用品商店找到。
Video Sentinel包含一个微控制器（来自Rabbit的RCM3200），其中一个以太网端口配置了
固定的IP地址。默认情况下，Video Sentinel框的IP地址为
为10.0.0.50。 此地址在zh-b $ b微控制器的固件中设置，并允许在本地网络中使用Video Sentinel框。
。 但是，如果需要不同的IP地址，可以在Sandia更改
固件。
用于与视频通信的网络接口卡
Sentinel盒应设置兼容的IP地址。 例如，I $
通常将NIC的IP地址设置为10.0.0.2，并将子网
Mask设置为255.0.0.0。将来自视频
摄像头的传入视频电缆连接到Video Sentinel上的BNC连接器。
插入电源交流电源线，并将电源DC连接到Video Sentinel电源输入端。
打开电脑。
===============
随着一切就绪，一个人启动相机软件，然后按下连接按钮。它应该变绿，但什么都不做。软件的显示窗口中没有绿色按钮且没有图片。注释？
使用网络监视器，您可以开始捕获，按下连接按钮，然后查看正在传递的流量类型。  你应该离开你的盒子并前往10.0.0.50地址。 您可以在ipv4.address == 10.0.0.50，
上应用显示过滤器，这会将流量范围缩小到此设备。 如果您看到流量，请复制并粘贴摘要中的所有行并粘贴到回复中，以便我们查看。
如果没有发生这种情况，那么其他问题就出错了 在这种情况下，我会从命令提示符下键入ipconfig / all并将其粘贴到回复中。
谢谢，
Paul
I'm trying to install camera software on a friend's XP. Actually, the camera is outside the house, and there's an intermediate box connected to the PC by an ethernet cable (crossover). The camera is plugged into the box. I'm pretty confident that we
have the right TCP/IP addresses.
If I get to Control Panel, I see two network icons: LAN and RealTek8139. He doesn't really have a LAN. I'm guessing the realtek port is the the ethernet port on the PC.
Here are comments from the users manual on the hookup:
===========
Connect the Video Sentinel box to your PCs Network Interface Card (NIC).
If you are connecting the Video Sentinel box to the computer through a
hub, then standard Ethernet cables should suffice (10/100Base-T). If,
however, you want to connect directly from the
PC to the Video Sentinel box, you should use a crossover Ethernet cable.
Either cable type can be found at office supply stores.
The Video Sentinel box contains a micro-controller (RCM3200 from Rabbit
Semiconductor) with an Ethernet port that has been configured with a
fixed IP address. By default, the IP address of the Video Sentinel box
is 10.0.0.50. This address is set in the firmware of the
micro-controller and should allow the Video Sentinel box to be used
in a local network. If a different IP address is required, however, the
firmware can be changed at Sandia.
The Network Interface Card that you use to communicate with Video
Sentinel box should be set with a compatible IP address. For example, I
typically set the IP address of the NIC to 10.0.0.2 and set the Subnet
Mask to 255.0.0.0. Connect the incoming video cable from the video
camera to the BNC connector on the Video Sentinel.
Plug in the power supply AC power cord and connect the power supply DC
cable to the Video Sentinel box power supply input.
Turn on the PC.
===============
With everything in place, one fires up the camera software, and presses the Connect button. It should turn green, but does nothing. No green button and no picture in the software's display window. Comments?
Using Network Monitor you could start a capture, press teh connect button, and see what kind of traffic is being passed. You should something leave your box and head for the 10.0.0.50 address. You could apply a display filter on ipv4.address==10.0.0.50, which will narrow down the traffic to just this device. If you see traffic, copy and paste all the lines in the summary and paste in to a reply so we can take a look.
If this doesn't happen, then something else is wrong. In that case I would type ipconfig /all from a command prompt and paste this into a reply.
Thanks,
Paul
