user35288: Good day,
I have a sensor which supports serial data output using RS422 which has 4 wires (RX+, RX-, TX+, TX-)
my question is how can I connect this sensor to the Arduino.
I read that i can use 2 max485 chips to do this but uncertain of the exact procedure.
Thanks in advance.

They look like this:
