In the ever-changing world of technology, new devices become old news almost as soon as they are released because they are surpassed by upgraded versions. Remaining relevant for five years is the equivalent to a lifetime in terms of technology.
RS-232 has achieved technological immortality by remaining a viable standard for more than 50 years.
RS-232 is a telecommunications standard for serial communication transmission of data. Mainly used in computer serial ports, it connects data terminal equipment, such as a computer terminal, to data circuit-terminating equipment, such as a modem.
RS-232 was a standard feature on most personal computers to connect printers, modems, mice and other devices. Today, it is used extensively in embedded computer development systems, scientific instruments and industrial control equipment.
Everyday applications of RS-232 include gas pumps that allow you to pay at the pump with a credit card and healthcare technology such as mobile MRI units, fetal monitors and kidney dialysis machines.
RS-232 serial ports are also used to communicate to headless systems, such as servers that don't have a monitor or keyboard, and in embedded systems when no network connection is available.
RS-232 is a proven technology that is cost effective, flexible and widely available. It uses simple wiring and connectors, features easy set-up software and is built-in to most embedded processors.
Wireless RS-232 expands on the system's capabilities with extended range, portability and ease of installation. Plus, new and legacy systems can use wireless RS-232 connectivity.
RS-232 has proven itself in an industry that is in a constant state of evolution. After more than half a century, it continues to gain applications. Long live RS-232 - the immortal standard!
