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

In some electrical industries, we can involve RS-232C protocols. As the network expands, all walks of life will apply it to different places. So now the RS-232C Protocol holds some network applications. RS-232-C The RS-232C protocol is the EIA-RS-232C protocol, in which

In the electrical industry, we should be familiar with RS-232C protocols. As the protocol standard for voltage signal control, it has been applied in many fields. Next, let's take a brief look at this protocol. First, let's explain the specific meaning of this Protocol. RS-232-C The RS-232C protocol is the EIA-RS-232C

In our computer, interfaces and some bus functions and functions are standardized through some specific standards and protocols. Here we mainly introduce the RS-232C protocol for you. This Protocol has been applied not only in the computer field, but also in some electrical and mechanical fields with the development of this industry. Let's take a closer look at this special protocol. RS-232-C The RS-232C pr

API oil inventories fell 1.1 million barrels a day earlier this morning, the oil price of WTI rose by $45 per barrel, but the EIA oil inventories were reversed, and the U.S. Energy Information Agency (EIA), Beijing time, Wednesday 22:30 Published as of April 22, when the weekly crude oil inventories increased by 1.999 million barrels, the expected value is increased by 2.366 million barrels, the value of th

We know that the use of RS-232C protocols is well-developed in some areas of electrical and mechanical, and the basics of this are also described in previous articles. So as a supplement, we next to the RS-232C protocol interface signal to a comprehensive summary. I hope this will help you. RS-232C protocol standard interface has 25 lines, 4 data lines, 11 contro

Why do the EIA and the big market when others make a profit and you explode a position? Investment and financial management is not the overnight of the matter, the previous loss, does not represent the late loss, the previous profit, does not represent the latter profit. Therefore, the loss of friends do not be discouraged, profit friends do not be complacent, so that their peace of mind rational investment. Choose good will give accurate analysis, r

CD (8th leg): Carrier detection (receiver line signal detector), input. Indicates that the modem is connected to the telephone line.7. If the communication line is part of the Exchange phone, then at least two signals are required:8. RI (22nd foot): ringing indication, input.

RI (22nd feet): indicates the ringing, input. If the modem receives a ringing call signal from the switch station, it sends this signal to inform the computer or terminal.9. (20th feet): The data terminal is ready for output. After receiving the RI signal, the computer sends the signal to the modem as the

The connection string is also divided into two parts: pass-through and cross. The connection is generally used to prolong the connection between the PC and the device. 2, 3, and 5 are connected to 2, 3, and 5 respectively, because the PC is generally a public head, most of the devices are headers, so they are common and can be used for extension or connection. Crossover is generally used for connection between PCs, set 2 to 3, 3 to 2, 5 to 5. Generally, both ends are mother-headed! Before the co

The serial cable can be divided into straight chain and intersection. Generally for straight line extension PC equip, will 2, 3, 5 connect 2, 3, 5, because PC universal male. But the devices are mostly female, so they are just plain, and it can also be used to extend the connection; the crossover PC is connected to the PC with 2 pairs of 3, 3 pairs of 2, 5 to 5, and the general two are female at both ends!Before the computer appeared, the EIA establis

The serial line also points through and crosses, pass-through is generally used to extend the PC and equipment, will be 2, 3, 5 respectively connected 2, 3, 5, because the PC is generally male, and the device is mostly female, so just they are universal, can be used for extension can also be used for connection; crossover is generally used for PC docking with PC, 2 to 3, 3 to 2, 5 to 5, usually both ends are female!Before the computer appeared, the EIA
