The RS 485 protocol is standard for sending serial data. It uses a pair of wires to send a differential signal over distances up to 4000 feet without a repeater. The differential signal makes it very robust, RS-485 is one of the most popular communications methods used in industrial applications where it's noise immunity and long-distance capability are a perfect fit. RS-485 is capable of multi-drop communications - up to 32 nodes
RS-485 can be configured for their half or full duplex. Half duplex typically uses one pair of wires, full duplex requires two pair.
RS-485 Tech Tip: Always run a signal ground with RS-485
