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 protocol, in which EIA (Electronic Industry Association) represents the American Association of electronics Industry, RS (recommeded standard) represents the Recommendation standar

the analog signal received by the modem to a digital signal, which is the modulation and demodulation of the signal.The device that implements the modulation and reconciliation task is called a modem ). When band transmission is adopted, both parties connect to a modem to transmit digital signals on analog signals (carriers. Therefore, this transmission method is also called the carrier transmission method. At this time, the communication line can be a telephone exchange network or a dedicated

At commandAt refers to attention. The AT Instruction Set is from the terminal device (terminal equipment, Te) or data terminal device (data terminal equipment, DTE) to the terminal adapter (terminal adapter, Ta) or sent by data circuit terminal equipment (DCE. Send AT commands via TA and te to control the functions of Mobile Station (MS) and interact with GSM network services. You can use AT commands to control calls, text messages, phone books, data

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 protocol is the EIA-RS-232C protocol, in which EIA (Electronic Industry Association) represe

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 EIA (Electronic Industry Association) represents the American Association of electronics Industry, RS (recommeded standard) represents the Recommendation standard, 232 is the identification number, C Represents the latest version

one of the most widely used serial interfaces in PC and communication industry. A RS-232 is defined as a single-ended standard that increases communication distances in low-rate serial communication. The RS-232 adopts the unbalanced transmission mode, that is, the so-called single-ended communication. Figure 1 (see the figure below) The data signal sent and received is relative to the signal location. For example, the data sent from the DTE de

digital signal into an analog signal, and the receiver uses the demodulator to convert the received analog signal into a digital signal, which is the modulation and demodulation of the signal.The device that implements the modulation and demodulation tasks is called a modem. When using the frequency band transmission, each side of the communication is connected to a modem, and the digital signal is sent to the analog signal (carrier) for transmission. Therefore, this transmission is also known

It grants different types of files) and different domain names to processes for access control, access to other domains from one domain and access to different types from one domain must be controlled by the DTE p

Understanding Serial Communications There are many kinds of serial communication protocols, such as rs232,rs485,rs422, even the popular USB is serial communication protocol. And the application of serial communication technology is everywhere. Perhaps everybody sees most is the computer serial port and the modem communication. Remember when the PC was first popular in China (about five years before the 90 's), when someone even used a serial line to

Before talking about this, we will first introduce another concept, DCE (Data Communication Equipment) speed. It refers to the transmission speed between two modem devices, that is, between telephone lines. We call 56k the speed. DTE (data terminal equipment) refers to the transmission speed from the local computer to the modem. If the telephone line transmission rate (DCE speed) is 56000bps, after receiving the data, the modem decompress 56000 × 4 =

From https://www.ibm.com/developerworks/cn/linux/l-serials/ Introduction to serial ports The serial port is a common interface for computers. It has a wide range of applications, such as a few connection lines and simple communication. Commonly used serial port is RS-232-C interface (also known as EIA RS-232-C) it was in 1970 by the American Association of Electronic Industry (EIA) the serial communication standard jointly developed by Bell systems, modem manufacturers, and computer terminal ma

Line Protection basically requires that the devices connected to the internet have a ground line, including hosts, workstations, hubs, switches, routers, and MODEM connected To routers. A terminal or PC configured with a Cisco router must also use a valid power supply. Cisco synchronous serial interfaces are commonly used. Different interfaces can be obtained through different cables. Such as RS232 and V.35. In addition, the cables of Cisco synchrono

Serial Port is also called "Serial Port". It is mainly used for serial data transmission. Common RS-232 with general computer applications (using 25-pin or 9-pin connectors) and half duplex RS-485 for industrial computer applications with full duplex RS-422. Serial interface according to electrical standards and protocols, including RS-232-C, RS-422, RS485, USB and so on. RS-232-C, RS-422 and RS-485 standards only regulate the electrical characteristics of the interface, does not involve connec
