WebSep 25, 2024 · Can the CAN bus terminating resistor be “removed” from the Tracker One via some jumper pads? Or the only way is to remove the terminating resistor? (Where is it located?) I have an existing CAN bus network with 120 ohms resistor on each end and introducing the Tracker One will bring the line resistance to 40 ohms. 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
