WebAug 29, 2024 · Tip #1: Measure the resistance The most common CAN-Bus issue is too much or too little termination resistance. In a low speed CAN each device should have a 120 Ohm resistor. In a high speed CAN … 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
http://www.ece.uprm.edu/~mjimenez/inel6079/lectures/termination_techniques.pdf WebAug 25, 2024 · CAN bus drivers can only pull the bus into a dominant state, where CANH > CANL. The only mechanism to pull the bus back into the recessive state (CANH = CANL) is the resistor on each end. Therefore it simply cannot work without at least one resistor across the bus no matter how short or slow it is. Logged CEL Reliable Electronics
