Depending on the structure of your CAN network, it must be provided with a
120Ω resistor at the beginning and end between the CAN high and the CAN low
line.
3. The switch for the CAN-Termination
resistor (8) is located to the right of
the CAN port (9).
If the switch is on the left (factory
setting), no CAN bus termination is
set.
If the switch is on the right, a CAN
bus termination resistor of 120
Ω is
set.
