aui to rj45

Routers have a pivotal position in computer network, and are the bridge of computer network. It can not only connect different networks, but also choose the path of data transmission, and can block illegal access. The configuration of routers is not very easy for beginners. Now the general configuration of the router and simple debugging introduced to everyone, for friends in the configuration router reference, this article take Cisco2501 as an example. The Cisco2501 has an Ethernet port (

to DDN, frame relay, X.25, and PSTN (analog telephone line ).· Synchronous/asynchronous serial port, which can be set as synchronous working mode by software.· AuI port, that is, the crude cable port. Generally, an external converter (AUI-RJ45) is required to connect to the 10base-t Ethernet network.· The ISDN port can be connected to the ISDN network (2B + d) a

Ethernet is up, and line protocol is down.The host 10 m Nic is connected to the M Ethernet port of the router. It is not adaptive (current version). Otherwise, no problem occurs.If the coaxial cable is used, check whether the cable, T-header, and terminator are correctly connected.If it is a twisted pair, check whether the cable is correct and whether it is connected through the HUB in the middle. If it is a direct connection host, use a crossover line.If the 100BaseTX interface is used, five c

required for data transmission and receiving, and provides standard interfaces to the data link layer equipment.The data link layer provides addressing mechanisms, data frame construction, data error check, transfer control, and standard data interfaces to the network layer. 2There is also a Network Transformer between PHY and RJ45, also known as the data pump, which is a device on the consumption-level PCI Nic. The data pump is also called a Network

From http://bbs.pcsoft.com.cn/thread-138952-1-4.html The network location of a vro is complex. It can be an internal subnet edge or an internal or external network edge. At the same time, to achieve strong applicability, it needs to connect to a variety of networks, so that its interfaces must be diverse. Not to mention network enthusiasts, but many network administrators cannot make it clear. To this end, I would like to introduce all kinds of interfaces and Connection Methods of routers. I. ro

used normally, the general router has a control port "console ", it is used to connect to a computer or terminal device and configure a router through specific software. Next, let's take a look at the router's LAN and WAN connection ports. 1. LAN interface According to the interface name, we can see that these interfaces are mainly used to connect routers and LAN, because the LAN type is also diverse, therefore, the LAN interface type of the router may be diverse. Different networks have di

interface Common Ethernet interfaces include AuI, BNC and RJ-45 interfaces, as well as FDDI, ATM, Gigabit Ethernet and so on all have corresponding network interfaces, the following describes the main LAN interfaces. (1). AuI PortThe AuI port is the interface used to connect to the coarse coaxial cable. It is a "d" Type 15-pin interface, this is one of the most

inserted.Step four: Then on the network card on the top of the screw hole with the main box docking, screw the screw to make its network card become more stable.Step Five: Finally, we will test whether the NIC is connected to the motherboard. We use an Internet cable to plug in the network card RJ45 interface, the normal network card indicator lights up.Note: After installing the network card is not necessarily able to connect the Internet, because s

inseparable, we can adopt blocking measures. Table 1 Distance between Integrated Wiring and electromagnetic interference sources 8. How do I connect to a 10 m network with a long distance? When connecting a 10 m network that exceeds m to M, there are usually three methods in the project: 1) Use a repeater. Use a thin cable, plus 3 ~ Up to 500 m for the four reconnections. If it is a twisted pair, you can use the HUB) to extend the transmission distance, but up to 180 m.

The local area network is the individual computer or the terminal, uses the communication line to connect each other, follows certain agreement, carries on the information exchange, realizes the resource sharing. Among them, communication lines, that is, transmission medium commonly used: twisted-pair, coaxial cable, optical fiber and so on. From the cost-performance and maintainability, most LANs use unshielded twisted pair (utp-unshielded Twisted Pair) as the transmission medium to network. T

Through the previous few posts. We analyzed the AUI cache, the tool class, the display and loading of the code. Today, we continue to study the source code of AUI, the core Auxiliary tool class in learning.I hope you can learn something in it, ha.DownloadTo download a picture, we imagine what we need: first we have to set up a supported protocol.
