Terminating resistor
A terminating resistor for the CAN interface is already integrated on the IF option. A switch is provided to enable
or disable the terminating resistor. However, the side cover must be removed from the system unit in order to do
this (see Installation - Interface option, steps 1 to 4). An active terminating resistor is indicated by a yellow LED.
