Jan 29, 2019 · The formal standard that later became mainstream was EIA 232 C, where EIA is the standard institute and C is revision. This one is sloppily referred to as RS-232-C, since RS-232 is …

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 …

Dec 21, 2024 · In RS232 serial communication as pictured below how does one ensure the bit stream is always read at the start/stop bits? I’m looking at this waveform and considering a case where two …

Dec 31, 2024 · 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 EIA/TIA-232 and an optional mounting variant to 3V3-TTL.

I have an old piece of instrument that suppose to connect with a Windows XP machine. I keep getting "Framing Error" messages on the instrument panel while the PC side shows that the instrument coul...

Dec 27, 2022 · From the parts (complementary BJT transistors and discretes near the connector) I think it's a non-standard RS-232 port that idles at 0V rather than -9 or whatever.

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 …

I have used UART RS232 communication between MCUs extensively. Now I need to interface my STM32F407 MCU over RS485 bus with with devices. I have understood few things about RS485 but …

Apr 1, 2025 · Many devices use +/- 12V, up to +/- 25V needs to be tolerated. If you want better, don't put any circuitry to RS-232 side. You also need to define what is better to you - random circitry affecting …

Aug 2, 2024 · The sellers just don't understand what they are selling and label it wrong. RS-232, while still relevant being over 80 year old standard, isn't so common anymore that everyone these days …
