The LPB is used as a communication basis for generating a system with additional
SIGMAGYR™ controllers or controllers of other manufacture.

Entry of the device address is especially important when used in a system. The ad-
dresses classify the controllers within a segment.
Within a segment, the RVP540 / RVP550 can only be used as a standalone controller
(0) or master (1). The controller cannot be connected to some other master as a slave.
