    Can bus topology and termination a can bus consists of two or more can nodes cabled together. The can_h and can_l pins of each node are connected to the main can bus cable through a short connection known as a “stub.” the pair of signal wires, can_h and can_l, constitutes a transmission line. If the...

    Termination resistors the termination resistors (rt) should match the nominal impedance of the can cable and therefore comply with the values in table 3. The onboard, software-selectable termination has a nominal value of 120 Ω. If you are not using the onboard termination, use the values listed in ...
