Ethernet is by far the most popular LAN protocol used today. It is so popular that if you buy a network card to install on your machine, you will get an Ethernet card, unless you ask for something different, if of course that different protocol is available. Ethernet has evolved over the years. Serial means one event at a time.
It is usually contrasted with parallel , meaning more than one event happening at a time. In data transmission, the techniques of time division and space division are used, where time separates the transmission of individual bits of information sent serially and space on multiple lines or paths can be used to have multiple bits sent in parallel.
In the context of computer hardware and data transmission: serial connection, operation, and media usually indicate a simpler, slower operation and parallel indicates a faster operation. On your PC, the printer is usually attached through a parallel interface and cable so that it will print faster.
Your keyboard and mouse are one-way devices that only require a serial interface and line. Inside your computer, much of its circuitry supports bits being moved around in parallel.
Serial communication between your PC and the modem and other serial devices adheres to the RSC standard. Conventional computers and their programs operate in a serial manner, with the computer reading a program and performing its instructions one after the other. Considered to be one of the most basic external connections to a computer, the serial port has been an integral part of most computers for more than 20 years.
Although many of the newer systems have done away with the serial port complvcely in favor of USB connections, most modems still use the serial port, as do some printers, PDAs and digital cameras. When converting one end to Ethernet, the signal is able to travel farther. When devices are spread out over a large area or placed inconveniently, such as ceiling-mounted projectors, being able to control multiple devices from one spot saves time and money.
Only patience is required to make these cables; no prior knowledge necessary. It will take around an hour to complete a cable. After a few practice cables, they can be made in 10 to 15 minutes. With the ability to control devices from a stationary spot, you don't have to worry about searching for a remote or physically pushing buttons on the device. Caution: Make sure to push wires as far back as they will go into the 4-pin wire splicers to ensure a proper signal flow and avoid malfunctioning cables.
Usually you should try to match the color of the cables for best appearance. I only had red tape! You now have a hopefully working 9-pin serial to Ethernet cable. If there is a problem, it usually has something to do with mapping designated pins with correct inner cables. First, try to re-crimp the 4-wire splice connectors to ensure a solid connection.
Then go back and check your cable mappings. Think of all the other cables you can cross with an Ethernet cable!
