Male pinout of a 25-pin serial port (D-subminiature, DB-25) commonly found on 1980s computers. The following table lists commonly used RS-232 signals (called "circuits" in the specifications) and their pin assignments on the recommended DB-25 connectors [14] (see Serial port pinouts for other commonly used connectors not defined by the standard).

Ultimate RS232 Pinout Guide | Detailed 9-Pin Diagram and Explanation. The RS232 pinout defines the purpose of each pin in the 9-pin RS232 connector, crucial for serial communication between devices like computers and modems. This guide will help you understand each pin's role and how to use them efficiently. Key Takeaways

2022年6月6日 · RS-232 is the standard serial communications interface found on many types of equipment such as computers, modems, printers, Microcontrollers, eprom programmers, and a host of other devices. RS232 pinout may be varied.

2022年6月6日 · PC serial port is based on RS-232 standard, you may find signals details in the RS-232 interface pinout. RS-232, when compared to later interfaces such as RS-422, RS-485 and Ethernet, has lower transmission speed, short maximum cable length, large voltage swing, large standard connectors, no multipoint capability and limited multidrop capability.

2018年4月8日 · RS232 connector is a port used for data exchange between equipments. It was designed for data exchange between DTE (Data Terminal Equipment) or PC and DCE (Data Communication Equipment) or MODEM. The need for RS232 came from limitations raised by parallel data exchange.

The RS232 standard specifies the electrical characteristics and connector for an all encompassing point-to-point modem interface. Although the original specification was intended for modems, subsequent renderings shed unneeded signals to expand its scope and use as a general purpose serial interface at data rates up to 1MB.
