1. Two modes of transmissionThe controller can be set to two modes of transmission (ASCII or RTU) in any one of the standard Modbus network communications. Users choose the desired mode, including serial communication parameters (baud rate, check mode, etc.), in the configuration of each controller, all devices on a Modbus network must choose the same transmission mode and serial port parameters.The selecte

-based approach non-blocking I/O uses epoll Epoll () and non-blocking IO driven by JNI. This transport supports only a variety of features available on Linux, such as So_reuseport, faster than NIO transmissions, and is completely non-blocking linux use oio using the java.net package as the basis-using the blocking stream blocking I/O using local Local transport Both the cli

How about the millet fast pass? 1, transmission speed is dozens of times times the Bluetooth can be free biography of your mobile phone files, but also do not need traffic, this and Bluetooth is just the same speed than Bluetooth dozens of times times oh; How did the Millet express disappear? The previous version of the MIUI has this function, and then disappeared after the update, you can download the Millet Fast Pass on the use of O

Transmission is the default BitTorrent client for Ubuntu, recently released the latest transmission 2.90 version, currently available via PPA for Ubuntu 15.10, Ubuntu 14.04 and Ubuntu 12 .04 for an upgrade installation. Over N long, this updated transmission 2.90 brings MINIUPNPC API V14, Cyassl/wolfssl and Polarssl back-end encryption support, as well as various

Data Guard offers two main services:1 Redo Transport service: The Primay end of the redo log transmission to one or more standby destinations.2 Redo Application Service: The redo log which is transmitted from the Primay end is applied to the standby end.This article first discusses the redo transport services. 1, the use of ARCN transmission redo logby default, the redo log is transferred using ARCN, but o

Sometimes in order to test the network situation, it takes time to return each phase, such as DNS resolution, time spent establishing a connection, the time it took to establish a connection to the preparation of a transmission, the time spent building a connection to the transmission, the duration of the process, the amount of data downloaded, the download speed, the amount of data uploaded, Upload speed a

LAN (LAN) Chinese is the abbreviation of "Local Region network", the English full name is "Regional Area Network", it mainly refers to the Working Group Internet which is composed of server and multiple computers in a small scope, and belongs to a branch of computer network application. Because the network through the server to connect each computer, so the information in the local area network transmission rate is relatively high, but also to provide

The Traceroute tool is used to track the transmission path of datagrams: When a datagram travels from one computer to another, it passes through multiple gateways, and the traceroute command can find all the routers on the datagram transmission path. The transmission path traced through the Traceroute tool is just one of the many pathways between the two computer

　　An ink-jet printer has been used normally, recently moved the ground once, after the printer post is completed, the print head can not automatically move, open the printer disk cover, found that the printer's transmission belt is very loose, how to solve? The problem should be because you move the printer, the normal shutdown printer, resulting in the print head does not normal movement to the right fixed position, moving in the vibration, resultin

Is it usb3.0 to see the speed of the gods of others? Have you complained about the speed of your USB2.0? In fact usb2.0 the theoretical speed is 60mb/s, but most cases usb2.0 the highest actual transmission speed only 30mb/s, That is because USB2.0 uses the serial transmission mode of NRZI encoding, transmission of continuous 0, 1 strings, in the transfer process

The recent FTP transfer files to the Linux server, there is garbled situation, the transmission of the file name with Chinese characters.

Many units and companies set up their own local area network, but a newly built small LAN, a server, more than 10 workstations, using a switch as an access device, connecting lines to 6 types of lines. The main fault performance for the network in the computer transmission speed is slow, any one station on the server to copy a 100MB file, it should be 30 minutes. Even the adjacent two workstations are so slow. Failure analysis is tied to the followin

Recently has been running no problem FTP download program has been a problem, the prompt can not be decompressed. After analysis, I use filezilla manual download after decompression is correct, and my program use Apache.common.FTP package download that there is a problem, cannot decompress. Comparing the two found that the latter file size is large. Find data as follows, the code will transfer mode to binary transmission download, problem solving. for

1.1 Bandwidth The unit of bandwidth is "bit/s", which is the number of bits per unit time. We often say such as 100M bandwidth, the full name should be 100mbit/s, or 100Mbps. 1.2 How data is sent The transmission of data is generally through the following links: 1 The application will first write data to the memory address space of the process. Usually in program development This only requires a general Run-time variable assignment. 2 The application

In the current era of rapid development of the network, routers have a pivotal role. Because the router acts as the relay system in the network layer, it provides a routing and forwarding function of the data between the third layer network. Therefore, the router's function, role and basic configuration are as members of IT industry we must be proficient. Below, we will make a brief analysis of the router from two aspects: that is how to build a simple network environment in the experiment, and

thinking about channel utilization from the point of view of data transmission rate @ (computer network) (2014.36) host A and Host B between the use of GBN protocol: A Send window size is 1000, the data frame length is 1000 bytes, the channel bandwidth is 100Mbps. Each time a data frame is received, a short data frame is used to confirm (transmission delay is ignored). If the one-way

Wen/Xu Jianlin In the field of real-time multimedia, real-time visual and perceptual display will have more extensive development space, while the basic core technology for real-time video transmission is the coding standard of H. In this paper, the author tries to solve the two problems of the core of the coding and decoding, one is the process of encoding and decoding, and the other is the structure of the code stream, hoping to help the people who

Source: Encrypted transmission of data--tea encryption and decryption algorithm implemented on single chip microcomputerHeroes in doing data transmission, have not considered the data encryption for transmission, if the serial or wireless data to be transmitted in the encryption, it is not to increase the security of communications. Commonly used encryption and d

From the first contact with the HTTP protocol, I do not know what is going on, forming a false view that the HTTP protocol is a pure ASCII character protocol, that is, in the HTTP stream is not see the binary stream of the 0x00 value. In fact, the answer is that the content in the HTTP protocol can be a pure binary stream. http://my.chinaunix.net/space.php?uid=22568683do=blogid=84701 The process of HTTP transmission of ASCII text content is believed
