Hi people,
why Uart devices are connected to rs232 devices even though both are asynchronous standards?

You can connect UART to UART without the RS232 level shifters. Using the RS232 level shifters extends the distance you can communicate.Hi people,

As others have said, RS232 is the actually physical connection, with it's +/-12V swing - the protocol you're using is just standard serial, something like 9600N1 (depending exactly what you're using).Its not really anything..... RS232 seems to be the best protocol... so I created a 6mA current loop for the transfer.... 5v connection
Its my hy-brid but the protocol is definitely RS232
exactly!! :dnigel... I have always seen rs323 as a protocol.... Protocol is language communication.. I saw the hardware... -12/12 volt level shifting as an aide for this protocol.
I may have misunderstood
hang on.... Thinking about it... Why else would the chip be an rs232 converter...
