该接口通过在单条通信线路或一对线路（用于RS-485等差分信号）上顺序传输数据位来运行。它管理时序（波特率）、数据帧（起始/停止位、奇偶校验）和电气信号电平，以确保物联网网关与连接的串行设备之间可靠的点对点或多点通信。

RS-232 is designed for point-to-point communication over shorter distances (typically up to 15 meters) with single-ended signaling. RS-485 supports multi-point communication over longer distances (up to 1200 meters) with differential signaling, making it more suitable for industrial environments with electrical noise.
DB9 connectors are standard for RS-232 interfaces and are ideal for computer peripherals and test equipment. Terminal block connectors are better for industrial applications where secure, screw-down connections are needed for RS-485 networks, especially in environments with vibration or frequent cable changes.
Maximum data rate depends on the protocol (RS-232 typically up to 115.2 kbps, RS-485 up to 10 Mbps), cable length (longer cables reduce maximum speed), line driver/receiver IC quality, and environmental noise. Proper termination and impedance matching are also critical for maintaining signal integrity at higher speeds.
