Can I an RS422 interface to Arduino's serial pins? Ask Question 1 The RS422, much like the RS485, uses two lines for both the receive and transmit lines (one positive, one negative). From what I can find on the net, RS422 uses 0-5V digital communication, which is the same as the Arduino serial pins, right?
