发帖数: 3319 | 3 I called a technician to wire the ethernet line cat6a for me. He said he
only does cat6e or cat6. May I ask which is better, cat6, cat6a or cat6e?
Thank you very much. |

发帖数: 3319 | 4 哇，你这么一说，我得考虑cancel appointment了。这人以前是at&t technician, 后
来自己出来干了。angies list和yelp上review 都很好。
请问你觉得连那种ethernet cable好呢？我找找做home theatre的人问问。
多谢。 |

发帖数: 6474 | 5 这个patch panel是干什么用的？我是直接把ethernet cable接上插头插到switch上，
switch接router，router连DSL modem，这样千兆网走switch，无线网走wireless
router。我觉得高点无所谓，基本上是一次性设置，不会整天搞来稿去的。
ooma最好不要跟上述设备放一起，有时会有干扰。我把它放到远处的另一个etehrnet接
口上，无绳电话也不跟ooma放到一起（通过墙内的电话线放到另外一个房间），这样
ooma通话的效果最好。 |

现本子还对得起这价格。就是设计太nc了，i7的本子连gigabit ethernet都不给，还是
10/100的。wifi也不支持5Ghz。搞得备份到NAS超级慢...也不能用无线网看NAS上的
1080p... 大家说是不是得换个dual band的wifi card啊? |

发帖数: 2517 | 13 谢谢你的回帖。ONT 在哪里看？我家前面的人用的Fios，我准备这两天也开通Fios.
任何无限路由器都可以吗？我是不是应该先开通Fios，然后打电话给客服打开Ethernet
，然后再用网线接上路由器就可以有WIFI了？ |

发帖数: 1985 | 15 一个N-port的Ethernet Switch，请问它自己倒底有几个MAC地址？至少需要一个，再分配
一个IP，才具有可管理性。但如果要支持Spanning Tree的话，好几个port都往外发BPDU
，如果不是每个port有一个unique的MAC地址的话，其它Switch怎么能分辨呢？地址学习
好象也有问题。所以我的理解是只要是支持STP的Switch，每个port都需要unique的MAC地
址。Is that correct? Thanks for any comments. |

发帖数: 27 | 19 I assume you need to communicate with PLC remotely from GUI? In that case,
you need network programming,i.e., using Winsock2 which can send data (
binary or text) to PLC over ethernet.
You call call Winsock2 functions directly from GUI.
But I am not sure if this is what you are asking. I only know a little bit
about the hardware. |

我在自己的办公室上网,是WIN2000用的ETHERNET,
经常会莫名其妙的断掉网.查看LAN CONNECTION,
还是显示正常,我不得不手工的DIABLE,ENABLE 它.
才能重新连上.
以前我可以很容易的连上NEWS.SINA.COM.CN,
后来经常是一连这个网址,就掉网.
现在是彻底不行了.
还有其他几个也是这样的问题(正经网站)
我相信不是网管做的手脚.
大侠们遇到这种情况吗?
多谢了. |

发帖数: 1035 | 23 add CAN in ur list.
spi and i2c are more for the inter-chip comm like adc, mem, etc. i
personally don't like i2c, driver is always a problem. spi read and write is
still complex. these two are bit based so you need to understand each clock
.
uart is byte based so it's much easier, variaties of rs232 485 can do long
distance. but no frame so comm protocol has to implement crc header etc on
the application level.
ethernet and can are frame based. much easier to implement. but can is
expensive on t |
