5.2.3 Terminating resistors
• A CAN BUS system always requires 2terminating resistors.
• The 2 CAN BUS components furthest away from the control unit, measured by
cable length, are fitted with the terminating resistors.
• The CANBUS components either have a switchable terminating resistor
(DIPswitch5 on the sensors) or the terminating resistors are connected to the
free CAN BUS connection.

• The total length of the cables between the two terminating resistors must not
exceed 30m.
