Alternatively, an RS232 device uses text (ASCII) protocols. The main difference is that Modbus articulates the protocol type, whereas RS485 defines the protocol's signal level. When using an RS485 communication device, the aforementioned distinction means that … lightmatic mod

"WebMay 10, 2024 · The main difference is that RS-485 uses symmetric signaling. One line is 5 V and the other 0 V to signal one state, then flipped to 0 V and 5 V for the other state. This makes detecting the state very easy (a simple comparator, maybe with a little hysteresis), but presents a challenge in terminating the bus. " - Rs485 rs422 difference
