2.3 CAN bus termination

A High-speed CAN bus (ISO 11898-2) must be terminated on both ends with 120 Ohms.

Standard termination example.

The 120-Ω characteristic impedance twisted-pair cable must be terminated with an impedance of the same

value to minimized reflected waves that occur from miss-matched impedances. Bad terminal may cause signal

reflections and the transceivers of the connected CAN nodes (CAN- interface, control device) may not work.

The USB2CAN does not have an internal termination. Device must be used on a terminated CAN bus.
