Disconnect Function
The disconnect function means that the remaining LAN cable is disconnected from
the bus when the terminating resistor is activated. If the terminating resistor is
accidentally activated in the middle of the LAN cable, the error can be recognized
and localized immediately due to the nodes that are no longer accessible.
