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

the near-point detection, which may not work far away, the final check shows that the electrical characteristics of the network cable do not meet the requirements. 6. RJ45 crystal leaders are not close Inferior RJ45 crystal head is mainly spring piece is not close, often happen not compacted, at that time is through, after a period of time again when the phenomenon of breaking.

, but in some of the network card location is more jincu, with this protective sleeve will not be plugged in the end, and some of the protective sleeve is more hard, but make the crystal head of the card buckle not to the end, so that contact is 5, cable quality does not pass At ordinary times we may not care about the quality of the network cable, generally we commonly used in the network cable is less than 10, so the impact of poor quality network cable is not obvious, but in the LAN cabling i

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

believes that the advantages of special jumpers mainly have the following advantages: First of all, the special jumper once the electrical performance is higher than the manual on-site production products. The same super five wiring link uses the special jumper and the self-made jumper test respectively, usually its channel performance difference is about 30%. Secondly, the special jumper adopts multi-core core (usually 8 cores) and proprietary core fixing process, the physical characteristics,

In the early SAN storage system, the data transfer between the server and the switch was done through optical fiber, because the server was transferring the SCSI instruction to the storage device, could not take the IP protocol of the ordinary LAN network, so it needed to use FC transport, so this SAN is called Fc-san, And later appeared with the IP protocol encapsulated SAN, can completely walk the ordinary LAN network, so called Ip-san, which is the most typical of the now popular iSCSI. Both

I believe that many vro users still have a better understanding of vro configurations. Here we will mainly introduce the specific steps of vro configuration and debugging. vro plays an important role in the computer network, it is a bridge of computer networks. It not only connects to different networks, but also selects data transmission paths and blocks illegal access. Router configuration is not very easy for beginners. Now we will introduce the vro configuration and simple debugging for your

There are still many things worth learning about configuring routers. Here we mainly introduce Ethernet port configuration, X.25 configuration, and so on. Routers play an important role in computer networks and serve as a bridge between computer networks. It not only connects to different networks, but also selects data transmission paths and blocks illegal access. Configuring a router is not very easy for beginners. We will introduce general router configuration and simple debugging for your re

of the three cables for convenient use. The network cable is eight cores. Currently, four trees in the family have no practical use. You can use two cables as telephone lines, but the effect is not as good as that of a single cable. The telephone line also has 2-core, 4-core, and 6-core lines. It is also useful for two lines at home. The quality of cables is very important, especially coaxial cables). In my experience, if signal interference or attenuation is found, the problem may be caused by

. The 6e Cable supports 10 Gb network in the range of 100 meters. Compared with Category 5 and category 5e cables, Category 6 cables are not susceptible to crosstalk and external EMI noise. Industrial Ethernet cables are designed to withstand physical erosion of cables in more harsh industrial environments. Make sure that the RJ45 interface and socket can also be of Class 6 levels when installing 6 types of cables. It is best to use a pre-prepared plu

In 3-5 minutes, the wireless network connection experiences a signal decline. The signal drops to 11 Mbps, and the connection is exited and fixed. The fault is solved. In the overall debugging process, xiaobian also took a lot of steps, mainly due to lack of awareness of the WAN port. First, follow the previous steps to connect to the hardware conf

Nowadays, optical transceiver network devices are increasingly used in our network engineering. They are used in small-scale optical fiber trunk connection solutions, so it is better to use optical fiber interfaces for switches in large-scale optical fiber trunk. Because of the various types of optical fiber, wavelength, interface type, rate, and other technical indicators, a wide range of Optical Fiber transceiver products are available. How do we know which optical transceiver to choose? This
