Abstract

A lighting system having multiple network levels implements various addresses schemes to communicate messages among various devices. A master controller (10) or a slave translator (21) transmits a master message (MM) to a slave device (30, 31) at a lower network level, wherein the master message (MM) includes an address associated with that particular lower network level and assigned to that particular slave device (30, 31). In the case where the slave device is a slave translator (21, 31), the slave translator (21, 31) will translate the master message (MM) into a translated message (TM) and transmit the translated message (TM) to a slave device (30, 40) at a lower network level, wherein the translated message (TM) includes an address associated with that particular lower network and assigned to slave device (30, 40).
