- rs232 - What is the difference between RS-232 and RS-232-C . . .
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 such a well-known name
- serial - Electrical Engineering Stack Exchange
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 consecutive
- Could RS-232 data be carried over a standard 3. 5mm audio aux cable?
I am looking at RS-232 control for various TV displays which use a different type of input connector for RS-232 The combination of RS-232 inputs on different TV displays is the standard 9-pin DB9 connector or either a 2 5mm or 3 5mm input
- What standard defines the number of stop bits in RS-232?
wikipedia says that the RS-232-C (1969) specification fails to define many things, including character encoding, start and stop bits, and even the order of the bits One of the things defined is that enormous 25 pin D connector Later standards like 485 define more stuff, but whether they define the stop bits is another matter
- RS232 and RS485 sharing same wires
The between-signals twist would worsen crosstalk for RS-232, but again, it's highly unlikely this would be a problem There will also be a modest reduction in capacitance between power and data pairs, which RS-232 may benefit from
- What are TX and RX relative to? - Electrical Engineering Stack Exchange
RS232 pin naming is a bit of a special case because they defined things in terms of DTE (Data terminal equipment) and DCE (Data communications equipment) and managed to cause utter confusion DCE has the data output on the RX pin and input on the TX pin, DTE is the opposite In theory the sex of the connectors should tell you what is what, in practise enough manufacturers got this wrong to
- rs232 - What is the difference between RS-232 and TTL UART . . .
The port on your USB<->RS-232 converter will output something like + -9V and can accept + -25V or short circuit without damage The UART on your MCU uses logic level (0V 3 3V or 0V 5V typically) Applying less than 0V or more than Vcc can destroy the MCU chip Also the logic levels are inverted between the two types (excepting an option on a very few MCUs) To bidirectionally invert and
- serial - Difference between UART and RS-232? - Electrical Engineering . . .
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 protocol Am I correct?
