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
How do I know if its RS232 levels or TTL levels 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
Max Serial Cable Length? - Electrical Engineering Stack Exchange 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 bauds and RS
What is the difference between Ethernet and Serial communication? RS-232 is more or less easy to implement but is slow and has short range Ethernet on the other hand is very complex and is often looked as a part of larger networking stack and has greater range and is much faster
RS485 to RS232 conversion? - Electrical Engineering Stack Exchange There exists such conversion but it's not as simple as putting a cable with RS-232 standard male cable to a RS-485 standard female cable or vice versa The RS-485 standard protocol is very similar to RS-232 in terms of serial communications However, the RS-485 has , which basically means that it transmits information using two complementary signals NOTE: The circuit diagram above is an that
How to tell what serial protocol is used on a DB9 connector? The RS-232 DB9 is well standardized You'll have Rx on pin 2, Tx on pin 3 and GND on pin 5 Optional handshaking signals on the rest of the pins This assumes that the device is a terminal at the end of the bus Otherwise Tx Rx may switch places in case the device is to be regarded as a "modem", a middle man between terminals As seen on for example Wikipedia, RS-232 logic levels are 3V to 15V
Serial, RS232, Modbus, UART and TCP 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 TCP? TCP and seria
