RS232 SCHEMATIC INTERFACE
serasidisImage: serasidisRS232 is the voltage loop serial interfacewith full-duplex communication represented by voltage levels with respect to system ground. A common ground between the PC and the associated device is necessary. Hot-plug isn't supported, but sometimes allowed. Nowdays only 9-pin connector is still in use for PCs.

Modern hardware designs use innovative serial communication protocols like USB, Ethernet, and Wi-Fi. But still, RS232 has proven to be prominent.What is RS232 Protocol and How it Works? - Codrey ElectronicsSee all results for this questionWhat Conector is used in RS232?What Conector is used in RS232?The original pinout for RS232 was developed for a 25 pins sub D connector. Since the introduction of the smaller serial port on the IBM-AT, 9 pins RS232 connectors are commonly used. In mixed applications, a 9 to 25 pins converter can be used to connect connectors of different sizes.RS232 serial cable pinout informationSee all results for this questionWhat are the differences between RS232 and USB?What are the differences between RS232 and USB?An USBport is much more sophisticated than an RS-232serial port. Basically, an RS-232has a TX pin and an RX pin in which a given side transmits and receives data (respectively), and the other side has the same two crossed over, so one TX connects to the other RX and vice-versa (obviously).serial - What are the differences between USB and RS232See all results for this questionWhat is the function of RS232?What is the function of RS232?RS-232ports are also commonly used to communicate to headless systems such as servers, where no monitor or keyboard is installed, during boot when operating system is not running yet and therefore no network connection is possible.RS-232 - WikipediaSee all results for this questionFeedback

RS232 predates the PC, but even with EIA-574 and the later TIA-232-F the definitions still use DTE (Data terminal equipment - such as a PC or equivalent) and DCE (Data circuit-terminating equipment - such as a modem or 'dumb terminal' or any other device) as the frame of reference.
