RS-485 and MODBUS: Characteristics and Communication

RS-485 and MODBUS: Characteristics and Communication

RS-485 belongs to wired transmission, so it requires a hardware transmission medium, which can actually be just two wires. The signal transmitted over these two wires is the same; the sender splits this signal into two, but the receiver restores it to the original signal. The advantage of this method can be compared with RS-232; … Read more
