Abstract
The invention relates to a bus-capable device having an input interface and an output interface for connecting to a serial bus, particularly a CAN bus, wherein the input interface and the output interface each have at least one signal line connection, and further having a terminating resistor for terminating the bus and a switch apparatus for switching the terminating resistor active as a function of the connection status of the input and output interfaces, wherein the input interface and the output interface each having a supply voltage connection for providing a supply voltage to the output and/or input interfaces of a respective next bus-capable device and a feedback connection for receiving the supply voltage from an output and/or input interface of a respective next bus-capable device, wherein the switch apparatus has an evaluation circuit for determining the presence of the supply voltage at the feedback connections of the input and output interfaces and an activation circuit for switching the terminating resistor active when the supply voltage is found by the evaluation circuit to be absent from the feedback connection of the input interface and/or from the feedback connection of the output interface.
