rj45 to db25

Application of RJ45 short circuit ring on gigabit Nic1. Topic OriginFor those who often work on multiple operating systems, using Windows as the host system with Vmware Workstation is already a standard Workstation. I personally traveled back and forth between Windows and Linux and used the notebook configuration as Windows 7 as the host, VMWare Workstation 9 to install the Virtual Machine CentOS and OpenBSD. Virtual Machine network connection is set

The RJ45 interface is typically used for data transmission, and the most common application is the NIC interface. RJ45 is a type of different joints; RJ45 head According to the order of the line there are two different ways, one is orange white, orange, green, blue, blue, white, green, brown, Brown, the other is green, white, green, orange, blue, blue, white, or

Let's talk about the playing style and Tactics of RJ45 line sequence. The wiring standards of EIA/TIA define the line sequence 568a and 568b of the two twisted pair wires.568a standard:Green white -- 1, green -- 2, orange white -- 3, blue -- 4, blue white -- 5, orange -- 6, brown white -- 7, brown -- 8568b standard:Orange white -- 1, orange -- 2, green white -- 3, blue -- 4, blue white -- 5, green -- 6, brown white -- 7, brown -- 8 Note:568a:Green

We know that the cable is the basis of the network, if you do not well identify the use of the cable, you will not become a qualified engineer.The BNC cable is the copper shaft cable that we use for CCTV, which is used today as a signal input/output probe in an oscilloscope, although the appearance and the traditional cable are somewhat different, but the function is similar. It is mainly used in the network between the operator optical end machine to the router this link, is commonly known as t

RJ-45 is also used for other interfaces such as ISDN, pins are defined differently. Listen 48 connector: Used to connect T1, E1 serial lines, usually using shielded twisted pair wire; RJ-48 can also support pin3, pin6 Grounding Conn

RJ45 the definition and standards of the relevant provisions. 　　 RJ45 is a commonly used name, referring to the standardization of IEC (60) 603-7, using a modular jack or plug of 8 locations (8 pins) defined by the International connectors Standard. IEC (60) 603-7 is also the ISO/IEC 11801 International General cabling Standard Connection hardware reference standard. 　　 ISO/IEC 11801 standards regarding t

Author: it.com. cnhttp: // www.ccw.com.cn 19:26:19 I want to comment (0) Many people (including the author) think that 10 Base-T 10 m networks use four of the eight signal lines in the network cable, the 100 Base-t m uses all eight signal lines (or how fast ?). However, when the author recently used a 10 m direct connection method (switching between 1 and 3, 2 and 6, and shielding the other four lines) to connect the network cable, unexpectedly, it was found that the Network was being transmitte

When dealing with computer networks, it is inevitable that network cables should be used frequently. In fact, the production of Network cables is very simple, that is, to insert the 4-to-8-Core Cable of twisted pair wires into the crystal head

The market demand for Cisco routers has been very high. Here we mainly analyze the detailed knowledge of Cisco router configuration and RJ45 console connection, for accessing and configuring I0S on a new router, we must communicate with the Console port. After connecting a console terminal with the Console port configured by the Cisco router, you can start to communicate with the router. This type of terminal can be a non-intelligent ASCII terminal, s

During the experiment, we usually use the serial port to connect two routers. But what should I do if my serial port is used up? You can also use the aux port to connect two vrouters using PPP. We know that a router generally has an aux port. There are two interface types: RJ45 (for example, 25 series and 26 series ), another type is DB25 (for example, 45 Series and 7000 Series). aux is a DTE device, so two

interface plug-in cable we use complies with the serial port standards, it can be used flexibly in practice, various protocols are used in serial port interface standards for communication and Device Control.We have learned about the serial port protocol. In our daily work, we are most exposed to the external interfaces of some actual devices. How can we know from the shape that this interface is? How to define each pin of cables? Above we know the serial RS-232, RS-422 and RS-485 standards onl

Protocol, so long as we use the interface plug-in cable to meet the standard of the actual use of flexible, in the serial port Interface standards using a variety of protocols for communication and equipment control. The above we understand the serial port protocol, and our daily work in contact with the most is the actual equipment of the external interface, how we know from the shape that it is that kind of interface. Make a definition of how the cables are each stitch. We know that. Serial

Currently, the commonly used serial ports include 9-pin serial ports (DB9) and 25-pin serial ports (db25). When the communication distance is close ( The connector can be divided into the public header and the mother header: The public header generic pointer connector; the mother header generic finger socket connector. There are unified rules on the pins of all connectors, and the serial numbers are printed on the connectors. Check the serial numbers
