Impact of Not Using Termination Resistors in CAN Bus

Before performing CAN bus communication, it is important to ensure proper bus configuration, such as termination resistors. They are crucial components that affect bus communication. Below, we will analyze the effects of not using termination resistors solely from the perspective of signal amplitude and time constant, without considering signal integrity. Termination Resistor Requirements According to … Read more
