5.1 RS485 bus termination
The board includes a 120 Ohm resistor for proper bus termination of the RS485 interface. When this jumper
is closed, the resistor will be placed between the two differential bus lines RS485+ and RS485-.
5.2 CAN bus termination
The board includes a 120 Ohm resistor for proper bus termination of the CAN interface. When this jumper is
closed, the resistor will be placed between the two differential bus lines CAN_H and CAN_L.
