RS-485. A commonly used alternative, also in many industrial settings, are RS-485 connections. This is essentially an asynchronous serial connection (e.g. like an UART or RS-232 serial port), except that it uses differential signalling and is a multipoint bus. Differential signalling means two inverted copies of the same signal are sent over two impedance-balanced wires, which allows the ...
