Abstract
Abstract A theatrical lighting control network which incorporates a local area network for communication among a number of node controllers and control consoles or devices employed in establising lighting or other effects levels in a theater, film production stage or other performance environment. Use of the network eliminates the requirements for the majority of hardwiring for interconnection of consoles and other controller or monitoring devices to effects controller racks and provides great flexibility in location and relocation of various components of the system.
