RS485 uses a differential signal on a twisted pair of wires, which protects the signal integrity over hundreds of meters of cable length. The same wires are used for both transmitting and receiving, so you can only do one at a time. This is called half-duplex. Many subsea sensors and tools including sonars, water chemistry sensors, and manipulators use RS485 communication.\u003c\/p\u003e\n\u003cp\u003eThe BLUART has JST-GH connector ports and through-hole options for either serial UART or RS485 connections. Only one connection type may be used at a time.
