rs232 crossover

We may be unfamiliar with the practices and usage of twisted pair wires. For example, it is hard to remember how the standard wire head is implemented. It is also vague to know the cross Line (or direct line) used. Let's talk about some notes. Prerequisites 1. Twisted Pair pin position definition (the crystal head has no clip side, from left to right), as shown in table 1. For Table 1, we only need to remember two points: one is that only one, two, three, and six eight lines are used, and the o

called winex. When wine is still the MIT software, rather than the current GPL, winex is separated from a branch of wine, because cedega does not belong to GPL, cedega no longer contributes to the development of wine code. With the lack of support for cedega, many people no longer use cedega to play games in Linux.5.4. Crossover Technically, crossover is not a third-party product of wine, but a major fina

Cedega includes a graphical interface for installing and running games, and added protection against copy protection software.Supported (no need to use cracking to avoid CD) (TRANSLATOR: Wine's support for anti-copy is not very good ). Cedega is not free of charge. The minimum purchase price is 3 months and 3 USD per month. If one year is prepaidYou can enjoy a d

available when creating an RJ45 crystal head, when a problem occurs at one end of a cable made by others, you have to look at the line sequence at the other end and try again to make the RJ45 crystal head at this end. How troublesome this is. In addition, it is very likely that crosstalk is caused by incorrect bypass .) 123 45678 The line sequence of t568a is: white green, green, white orange, blue, white blue, orange, white brown, brown The line sequence of t568b is: White orange, orange

The Chinese name of the KDJ indicator is a random index, originated from the futures market. The application rules of KDJ indicators are three curves. The application mainly involves five aspects: the absolute number of KD values, the form of KD curves, and the crossover of KD indicators; the deviation of the KD indicator; the value of the J indicator. First, consider the KD value. The KD value ranges from 0 ~ 100, divided into several areas: 80 or a

We know that on Linux, Deepin do a lot of wine applications, but there is no such treatment on other Linux distributions, let me show you how to run Deepin's wine application on the Linux distribution of Debian.The Linux distribution I use is Linux mint17.3, other Linux distributions please self-testNote: The contents mentioned in this article shall not be used in illegal ways, and the problems arising in the course of use are irrelevant to me.We know that Deepin's wine application is based on

Basic Concepts Genetic Algorithm (GA) is a smart search algorithm first proposed by Professor Holland of the United States based on the Basic Law of Nature "survival of the fittest, survival of the fittest. This rule is a good interpretation of the natural selection process of biological evolution. Genetic algor

The audio codecs adopt the CVSD encoding method. CVSD (Continuous Variable Slope Delta Modulation) is a continuous variable slope incremental modulation. It is an adaptive incremental modulation technology that can obtain high-quality audio encoding without resending voice packets. CVSD encoding is good at processin

How to configure a network device for connecting a notebook to the Console PortIf you use the Console port to manage CISCO devices, connect one end of the Console line to the Console port of the device, and the other end to the DB9 or DB25 interface of the computer.DB9 and DB25 interfaces are generally only available on the desktop. We cannot debug devices around the desktop every day. Instead, we often use laptops to debug devices, many laptops do not have the DB9 and DB25 interfaces, while USB

　The principle of fault detection in firewall systemAs most computers use Windows systems, firewalls also have their own systems, usually Linux, and computers, firewalls, if there is a failure, can be divided into software failures and hardware failures, hardware failures are more obvious, easy to judge, and software failure because the firewall is usually no information display or display of the small amount, it is not easy to judge, this need through the terminal software, the use of dedicated

The RS232 standard was born before RS485, but there are several deficiencies in RS232: The signal level of the interface is higher, to more than 10 V, the use of improper easy to damage the interface chip, level standard is also incompatible with the TTL level. Transmission rate is limited, can not be too high, generally to zero or zero bits per second (kb/s) to the limit. The interface uses signal lines an

Note the relationship between the source memory address and the target address when copying the address, that is, whether the source memory address and the target address are crossed. 1. If there is no crossover, you can directly copy the data in a loop. 2. If there is crossover, there are also two types of crossover. First: In this case, Src> = DST S
