Rs232 Cable

RS232 Cable 

A cable that connects to ports that are becoming legacy ports today. The RS232 cable was originally designed for teletypewriters and as this standard did not foresee what computers would become there were adapters to compensate for signal issues with newer technology. Some commands would lack otherwise as there would be missing control signals.

Uses today

Over time the USB has become the more standard cable system for connecting peripherals such as keyboards, mouses and displays to computers. This is due to them being faster and also the fact that they use lesser energy.

The RS232 cable is in use today but for more specific applications. It can be found in Programmable Logic Controllers, these systems control manufacturing processes on assembly lines. RS232 is used in laboratories for automation or surveying. Certain variable-frequency drives, servo drives and computerised numerical control equipment can be programmed using this cable. Another common use is with headless systems such as servers. Due to these more technical uses, computer manufacturers have provided the necessary porting options or adapters.

Comments

The advantage an RS232 cable does have over USB cables is that it is more immune to electromagnetic interference; an important edge in more technical environments as readings need to be more exacting.

RS232 cables are available for lower-end prices and one can also find many options for converters and converter cables so one can connect to older technology if needed.
