The RS-485 interface can be used in simplex of half-duplex modes with a single-pair cable. My understanding of 485 is - that the data uses a twisted pair, a common ground should go to all devices on the bus (which are usually isolated from protective ground [earth]), you may optionally shield the cable, this shield connects to gnd only at one point. Cabinet mounting Keep a distance to relays, their cables and other things emitting electric noises Cable connection and termination Modbus Max. Both are multi-drop, and both can communicate via very long distances, so then why choose one over the other? ... attenuation in the media, the amount and type of noise, and the sensitivity of the receiver to the signal and noise, affect the maximum possible data rate and transmission distance. Just to clarify that: One cable — … This standard fixes the problem of few connected devices in RS-422A.It is also called "EIA-485".RS-485 is forward compatible standard with RS-422A.The purpose and timing of the signal lines are defined, but the connectors are not.Many compatible products primarily adopt D-sub 25-pin and D-sub 9-pin connectors. It has been widely used for decades. RS-485 pinouts also have many variations, there is no single standard pinout arrangement or connector type, DB9, DB15, DB25, RJ-11, RJ-12, RJ-45 or DIN connector.
