In the modern era electronics, RS 232 is still a major thing. Nonetheless, the knowledge of what they are all about and the role they play is still not clear to many people. A lot of electronics now have ports for HDMI, THUNDERBOLT, and USB. With this new technology, many have assumed that the legacy interfaces are no longer useful. However, they are still very much useful. The RS 232 serial data interface is not just the oldest but also the most popular. In 1960, the Electronic Industries Alliance made a recommendation for the standards to be used for industries. The company went down in 2011. it is RS they chose though. The suggestions were quite many and RS 232 was in there too. Every PC you see on the market today has RS 232. Even so, it is not something out in the open. With the ports you see on the PCs, RS 232 does the packaging of the data and receives it. From there, the data is transferrable to a computing system or even a printer. For comparison purposes, the RS 232 can be said to be the post office in the computer world. If you have a USB port you would like to convert to RS 232 for a moment, you can find an adaptor for that.

If you come across a port using RS 232 data transmissions, it is what is referred to as the serial port. Besides the serial ports, you will also find parallel ports. For serial ports, the data transmission is one piece after another. However, data in parallel ports is transmitted in 8-bit bytes. If you want the RS 232 cable, you should go for the standard serial cable. You can easily identify it by the little screws at the sides and also the fact that it extends from the tower the monitor. You can see these on strain tension gauges, spectrometers, barcode scanners, computer terminals and also printers. Additionally, there are the same cables in GPS receivers, stenotype, stenograph, industrial, fieldbuses and even flat screen monitors. The data will come through the computer tower, and the RS 232 will transfer it to the monitor through the serial port where it is projected as an image. With all it can do, the RS 232 also comes with its limitations. When it comes to RS 232 cables, they do not go beyond three feet and if you want to transfer data in a distance longer than that you will have to find another option. However, even the cables available for this kind of work are not very effective. The longer cables are associated with higher risks and functional slowly. In addition, the RS 232 cable only in a series.
