  • Patent number: 9041319
    Abstract: A system incorporating an actuator connected to a polarity-insensitive two-wire communications bus. The actuator may have an electromechanical mover, a processor connected to the electromechanical mover, and a potentiometer, having a number of address settings, connected to the processor. A setting of the number of settings of the potentiometer may be a selection of an address for the actuator on the communications bus. There may be additional actuators and a controller connected to the communications bus. Each actuator may have an address which is different from an address of the other actuators connected to the communications bus. If an actuator is substituted with a replacement actuator, then a setting of a plurality of settings on a potentiometer of the replacement actuator may be selected to obtain an address that is the same as the address of the actuator which is substituted.
