I want to make an application in which I connect 2 distant micros using rs485. I intend to use max485 .I know that the output of micro is TTL. Will connecting micro directly to max485
will produce a 485 ? or should I convert the TTL to rs232 using max232, then connect its output to max485?
I wanna simple circuit which can convert TTL to RS485 as well as RS232, can you share me the circuit for design which takes TTL as input and gives out rs232/rs485 as output. I am planning to use max232 and max 485 IC. I don't know how connection are made. TTL input are coming from GPS Sensors.
i required connection in full duplex form
