network cables for network cabling. They are divided into two types: shielded and unshielded. If it is used outdoors, The Screen Shield is better. Generally, it is enough to use non-shielded five-category cables in the room. Because no Screen Shield is provided, the cables are relatively soft, but their connection methods are the same. In general, there are four pairs of lines twisted together in the cat5e category and marked with different colors. Twisted Pair wires have two Conn

1 cabling standard for copper-cable twisted pair Line 6 Integrated wiring copper twisted pair Line 6 line standard has been formally introduced. With the rapid development of computer technology, people's demand for fast communication has increased the requirement of high transmission rate of broadband belt, and the bandwidth of the integrated cabling system is increasing continuously as the communication platform of the network. Integrated wiring system copper twisted-pair line from 5 types of

Many members of the Subcommittee are concerned about how to name such a new system. supporters and opponents of this new system both stick to their positions and hold a heated debate. However, the real question is how much confusion the name of Category 8 will bring to the industry. Generally, the high level of a cabling system is a low level superset-meaning that the High Level cabling system meets and surpasses all electrical and mechanical requirements of the Low Level cabling system and is b

Introduction to serial port standard for RS-232, RS-422 and RS-485 1. The origin of RS-232C, RS-422 and RS-485RS-232, RS-422 and RS-485 are serial data interface standards, initially by the Electronic Industry Association (EIA) developed and released, RS-232 released in 1962, named as EIA-232-E, as industrial standard

specification, named as TIA/EIA-422-A standard. In order to expand the scope of application, EIA also established RS-422 standards on the basis of RS-485 in 1983, added multi-point, two-way communication capability, that is, allow multiple transmitters to connect to the same bus, at the same time, the driving capability and conflict protection characteristics of the transmitter are added, and the common mode range of the bus is extended, which is nam

RealCom name. Users who use the 232-to-net port for the first time are unfamiliar with this Protocol, here is an introduction. 232 is the abbreviation of RS232, which is a type of serial port. Here, the COM of realcom also refers to the serial port. We can see on the computer that COM1 and COM2 correspond to this 9-pin serial port, because the communication between early computers was dominated by serial p

RS-232, RS-485, RS-422 in the field debugging often encounter a variety of serial communication problems, such as RS-232, RS-485, RS-422, different ports of communication connection problem, usually between RS-485 and RS-422 conversion is very convenient. But when the RS-232 port and the RS-422 port communication, the site no other conversion mode, if the mail ma

Point:1. Serial Port and comport are physical interfaces (hardware ). While TTL, RS-232, RS-485 refers to the level standard (electrical signal ). 2. Generally, only Gnd RX Tx is connected to the device. Do not connect to the VCC or + 3.3v power cord to avoid power supply conflicts with the target device. 3. The pl2303 and cp2102 chips are USB-to-TTL serial ports. They use USB to expand the serial ports (TTL level ). 4, maxcompute chip is TTL level an

232. Implement Queue using StacksImplement the following operations of a queue using stacks. Push (x)--push element x to the back of the queue. Pop ()--Removes the element from in front of the queue. Peek ()--Get the front element. Empty ()--Return whether the queue is empty. Notes: You must use only standard operations of a stack--which means only push to top , peek/pop from top , size , and is empty operations AR
