3.6 Cabling
3.6.1 Termination
A High-speed CAN bus (ISO 11898-2) must be terminated on both
ends with 120 Ohms. Otherwise, there are interfering signal
reflections and the transceivers of the connected CAN nodes (CAN
interface, control device) will not work.
The PCAN-USB Hub does not have an internal termination. Use the
adapter on a terminated CAN bus.
3.6.2 Example of a Connection
Figure 6: Simple CAN connection
In this example, the PCAN-USB Hub is connected with a control unit
by a cable that is terminated at both ends.
