Jan 29, 2019 · I know about RS-232. Later, I heard about RS-232-C. Are these two standards the same or not? If not, what are the differences?

Aug 27, 2015 · What is the maximum length of serial cable I can use, to connection work properly? Is length of serial cable in connection with baud rate? I am using about 5 meter cable at speed 38400 …

Dec 11, 2016 · I always need to communicate with the TTL UART port on the MCU with a computer. When I talked about that, people always refer the UART port as an RS-232 port. Are they correct? If …

Aug 13, 2015 · I want clearly know this, Serial is protocol right? Then what is the Modbus? Is it under serial. And what are RS232 and RS485? What is UART and serial and UART same? What about …

Dec 31, 2024 · For RS232, I've seen other signals and such so I'm confused. From the info doc for PCB 1, the RS232 lines are a serial debug port with a bit rate of 250 kbps with voltage levels accurate to …

Aug 14, 2012 · What is the difference between RS232 and Serial? What are the core differences between all of these communication methods: reliability, cost, application, speed, hardware …

Dec 11, 2016 · Most of the time RS-232 and UART come together in serial communication theories. Are they both the same? From my readings I concluded UART is a hardware form of the RS-232 …

May 24, 2016 · What determines the peak voltage levels for RS-232 lines? Is it determined by the software? The hardware? Something else?

Jul 12, 2019 · RS232 is a per character high voltage (+/-4v min) protocol while I2C is a multibyte low voltage (3-5V) serial protocol. You need an MCU in between to do protocol conversion.

Jun 25, 2012 · RS232 was really designed to be an interface to a modem. That's pretty clear with signals named 'ring indicator', etc. It's been usurped to provide simple 3 wire (GND, TX, RX) bidirectional …
