Common CAN bus Problems: A Troubleshooting Guide

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. EDN DESIGN FEATURE Parallel termination, which is the simplest type, comprises a WebA CAN bus terminator can be used for termination of any high speed (ISO 11898-2) CAN bus system. The 120 Ohm terminating resistor is setup between pin 2 (CAN low) and …
