WebTerminal 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 14, 2014 · Generally, the bus should have a partyline topology and termination resistor have to be placed at both ends. One or even both might be omitted in short busses. Depending on the used connector standard, termination resistors are often plugged to the endpoint nodes.

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. The J1708 bus consists of two wires (A and B) with at least one twist (360°) per inch (2.54 cm) and a total length of up to 40 m.
