1. A vehicle comprising:
a first device coupled to a control area network (CAN) bus, the first device having
a first device identifier, the first device comprising:
a first resistor;
a first switch coupled to the first resistor;
a first identifier pin configured to receive a first binary signal; and
a first interpreter circuit coupled to the first identifier pin, the first interpreter circuit configured to set the first switch in a first switch position when the first binary signal is equal to the first device identifier, wherein, in the first switch position, the first resistor is coupled to the CAN bus; and
a second device coupled to the CAN bus, the second device having a second device identifier different from the first device identifier, the second device comprising:
a second resistor;
a second switch coupled to the second resistor;
a second identifier pin configured to receive a second binary signal; and
a second interpreter circuit coupled to the second identifier pin, the second interpreter circuit configured to set the second switch in a second switch position when the second binary signal is equal to the second device identifier, wherein, in the second switch position, the second resistor is not coupled to the CAN bus.
