of cables, we generally use software flow control instead of hardware flow control in general control communication. Generally, Xon/xoff is used to implement software flow control. The common method is: when the data volume in the input buffer of the receiving end exceeds the set high, xoff (19 in decimal or control-s in decimal format) is sent to the data sending end, the device programming specification should be described in detail). After receiving the xoff character, the sender immediately

different electronic wiring rack ports, Through the smart jumper according to the requirements of the map of the information point port and switch/voice distribution rack port of the wiring rack port for proper connection, and finally through intelligent management software to the integrated cabling system intelligent management. 2.3.5 Tobacco Enterprise Information Point Planning scheme The production automation degree of the new tobacco enterprise is very high, whether it is sil

Supplement: The wiring standards of EIA/TIA define the line sequence 568a and 568b of the two twisted pair wires.(1) 568a standard:Green white -- 1, green -- 2, orange white -- 3, blue -- 4, blue white -- 5, orange -- 6, brown white -- 7, brown -- 8(2) 568b standard:Orange white -- 1, orange -- 2, green white -- 3, blue -- 4, blue white -- 5, green -- 6, brown white -- 7, brown -- 8("Orange White" refers to light orange, or cables with orange dots or bars on the white line. The same applies to

through NAT technology, but its control functions need to be improved a lot. These software is very professional and generally not free, so large enterprises use more. 5. ADSL or residential broadband Internet access solutionBy using broadband cats and using dial-up software in the OS, you can use the pppoe protocol to dial up the Internet. To enable multiple machines to access the Internet, you can build a gateway through a router with the pppoe dialing function to guide other machines to acce

Whether it is a LAN, a metropolitan area network or a WAN, it is generally composed of network connection devices and transmission media such as NIC, hub, switch, router, cable, RJ45 connector, etc. Following the growing scale of the network, the number of devices that constitute the network in a rapid expansion of equipment, the variety is also constantly refurbished, may be the day-to-day maintenance of this series of equipment, without regular main

In this article, I will introduce intelligent physical layer management as a whole, and clarify related issues that are relevant to this emerging technology and have not yet been fully elaborated. What is intelligent cabling system Intelligent wiring System is the latest development of structured cabling document and management system. Although network administrators are accustomed to paper-based wiring records and subsequent simple spreadsheets, these methods do not real-time view network con

This is a series of two international standard lines developed by Super Five twisted pair to achieve performance index and unified wiring specification. (Can imagine: in the production of RJ45 Crystal Head, i

via the RJ45 cable to access the network, and the computer is set to "Automatically obtain IP address" and "Automatically obtain DNS address", which can be used as "broadband router" when "switch" use, Connect the network cable from the original computer to the LAN port on the router, and then make a network cable to connect the computer to the LAN port of the router (typically, the home broadband router has 4 LAN ports, 1 WAN ports), and the connect

USB PLUS This is because the E-sata interface itself does not power, so there is the above figure of the USB plus interface, is the E-sata and USB2.0 combination, to solve the e-sata does not provide power supply defects, this excuse is common on the high-end motherboard. IEEE 1394 Interface IEEE 1394 Interface IEEE 1394, referred to as 1394. Originally developed by Apple, known as FireWi

Ethernet Mac (link layer) +phy (physical layer/rtl8201f,88e1111), integrated DM9000,RTL8139CP because of the large amount of network data transmission, whether it is a separate type or integrated, it usually introduces DMA between MAC and PHY. Mac and PHY are separated because the Mac is part of the digital circuit, and the PHY is part of the simulation, responsible for the data received to the MAC layer, the MAC layer will receive the data transferred to the upper layer protocol, such as the IP
