In one embodiment, a communication circuit is configured for automated addressing in a network of series connected communication circuits. The communication circuit includes a voltage source and a switch connected in parallel between first and second data ports of the circuit. While operating in an addressing mode, a first voltage is sampled from a first data port while the switch is closed. The switch is opened to provide a voltage potential between the first and second data port and a second voltage is sampled from the second data port. An address of the communication circuit in the network is determined based on a difference of the first and second voltages.
