Please explain for RS 485 & RS 232 communication
Answer Posted / smita
RS232 is a full duplex cable means both transmitting and receiving happens at a time due to this noise will be more so that we can't go for longer distance
RS484 a half duplex cable means in a single time either transmitting or receiving will happen so we can go for a longer distance without disturbance
