🚧RS-232/485 (WIP)

RS-232 and RS-485 are both serial communication protocols used for data transfer between devices. RS-232 is commonly employed for short-distance communication, typically under 50 feet, and supports point-to-point connections at lower speeds. Conversely, RS-485 is designed for longer distances, up to 4000 feet, and supports multi-point configurations with higher data rates. The key differences include their physical wiring setups, signal voltage levels, and maximum distance capabilities.

RS-232 is often found in older computer serial ports, connections to modems, and in certain industrial applications where simple point-to-point communication is sufficient. For example, connecting a computer to a printer or a microcontroller to a GPS module.

RS-485 is widely used in industrial automation systems, such as connecting PLCs (Programmable Logic Controllers) to various sensors and actuators. It's also common in building management systems (BMS), where multiple devices like HVAC systems, lighting controls, and other peripherals need to communicate over long distances in a multi-drop network configuration.
