WebThe CAN bus must be terminated. The termination resistors are needed to suppress reflections as well as return the bus to its recessive or idle state. High-speed CAN uses … WebThis communication will require a properly designed CAN bus though if you want trouble free operation. In particular one of the common failing points is a CAN bus that either doesn’t have any terminating resistors, or one that has been fitted with multiple terminating resistors in the wrong locations.

Websition region, and bus contentions). The bus can be driven HIGH or LOW by an active driver, or biased to a known state by external pull up and pull down resistors. These resistors provide the FAILSAFE bias, and the termination configura-tion is also known as a “power termination”. The two bus states are shown in Figure 2.

WebDuring CAN communication the bus switches between dominant and recessive states, thus the short circuit current may be viewed either as the current during each bus state or as a DC average current.
