WebAug 25, 2024 · So the termination resistors on a CAN bus have 2 functions. Using a capacitor in series with a resistor at the end of the cable is a trick used with RS485. It makes it easier to have a reasonably high DC bias voltage on the bus (and thus noise resistance) when the bus is not driven by any of the nodes, while still having a low AC resistance ... WebChoosing the proper bus-termination technique—parallel, series, Thevenin, ac, or diode-based—is critical to digital-system performance. Improper termination can lead to ringing and stair-stepping, which in turn can cause false triggering and data errors.
