Simply, what is a RS-422 line? Additionally, what does it do/is it used for?
In: Technology
Rs422 is an industrial version of a serial communication line. Instead of a single TD and RD wires, both transmit and receive lines are balanced pairs (two wires). Similar to ethernet wire pairs. Because they are balanced, they have higher noise immunity, which allows longer transmitting distances and better reliability in electrically noisy environments with lots of motors.
