RS-232 Serial Line

The RS-232 serial interface communication standard remains one of the most widely used connections for serial data transmission due to its simplicity and reliability. Despite the emergence of new, higher-speed standards, RS-232 continues to offer robust performance.

Key Points:

• Widespread use: RS-232 is still found on some computers and many interfaces.

• Applications: It serves various purposes, from data acquisition to providing a serial data communication facility in general computing environments.

• Cost-effective: Products adhering to the RS-232 standard are readily available and affordable.

• Distance limit: The interface is designed to operate over distances of up to 15 meters, following a one master/one extension rule.

Application Examples:

1. Connection to simple devices: RS-232 is commonly used to connect to straightforward devices or other bus subsystems.

2. Audio/video and IR system integration: It plays a role in integrating audio/video systems and infrared (IR) devices.
