Termination
A High-speed CAN bus (ISO 11898-2) must be terminated at both
ends with 120 Ohms. Otherwise, there are interfering signal reflec-
tions and the transceivers of the connected CAN nodes (CAN
interface, control unit) do not work.
The PCAN-miniPCIe card does not have an internal termination. Use
the adapter on a terminated CAN bus.
