RS–485 Network (Modbus only)
RS–485 signals are for longer distances (1000 meters max.), and for multi-drop networks.
Use termination resistors at both ends of RS–485 network wiring, matching the impedance
rating of the cable (between 100 and 500 ohms).
RS–232 Network
Normally, the RS–232 signals are used for shorter distances (15 meters max), for
communications between two devices.
