Can bus without termination resistor
WebA value bigger than 60 Ohm typically indicates that there is at least one bus termination resistor missing or the bus terminators have a wrong resistance value. Finally the … WebJul 15, 2024 · CAN bus is open drain type, which relies on the termination resistors to return the dominant bus voltage back to recessive bus voltage. So it does not work without proper termination, as termination is not only used for transmission line effects. RS-485 on the other hand will often work for short lengths without termination, depending on many ...
