Web6 Bus Termination and Stub Length. Data transmission lines should always be terminated and stubs should be as short as possible to avoid signal reflections on the line. Proper … WebBoth ends must be terminated since the direction of propagation is bidirectional. In case of an RS485 twisted pair cable this termination is typically between 120 and 130 Ω. Here is a simple schematic of how the end of the lines should be terminated: "RT" is the 120 Ω termination resistor.
