Compatibility High Speed CAN Bus (ISO 11898-2) incl. CAN FD, SAE J1939, OBD2, NMEA, CANopen Connector Male / Female DB9 D-sub 9 pin 

Terminating resistors are required in CAN bus systems because the CAN communication flow is bidirectional. The terminals at both ends absorb the CAN signal energy, ensuring that the CAN signal energy is not reflected by the cable ends. Such reflections can cause interference and potential signal damage.

What is a CAN bus?

CAN bus, also known as Controller Area Network (Controller Area Network), is a serial communication protocol bus for real-time applications. It can use twisted pair to transmit signals and is one of the most widely used field buses in the world. . The CAN protocol is used to communicate between various components in a car, replacing expensive and bulky power distribution wiring harnesses. The wide use of CAN protocol makes it quickly extend to automation control and industrial fields.
