WebOct 12, 2024 · WHY CAN bus terminating resistor? Terminal resistors are needed in CAN bus systems because CAN communication flows are two-way. The termination at each end absorbs the CAN signal energy, ensuring that this is not reflected from the cable ends. Such reflections would cause interference and potentially damaged signals. WebAug 28, 2024 · Figure 2. High-Speed CAN bus topology. Most digital buses are driven high to represent a logic 1 and low to represent a logic 0. This is not the case with the CAN bus, that adopts a state called recessive, describing 1's, and a state called dominant, signifying 0's. In the recessive state, the termination resistors determine the bus voltages. WebJ1708 does not use the bus termination resistors used by RS-485. An RS-485 transceiver. (Picture borrowed from the J1708 spec) Note that this transceiver is, basically, the same as is used for the CAN bus.

In accordance with CiA 303-1 (matching our other devices/accessories) 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”.
