Remote Device Management or RDM is a protocol enhancement to USITT DMX512 that will allow bi-directional communication between a lighting or system controller and attached RDM compliant devices over a standard DMX line. This protocol will allow configuration, status monitoring, and management of these devices in such a way that does not disturb the normal operation of standard DMX devices that do not recognize the RDM protocol.

Relational Data Model. A specialized form of Relational Model set theory that is applied to data. It is manifested in relational data bases and Data Modeling techniques. The RDM defines data in terms of Tables that are n-ary relations. Tables contain Tuples of related data that depend upon embedded identity attributes (keys). Tables can be logically related through relationships based upon rules for embedded referential identity attributes (foreign keys). This allows related data to be extracted from multiple Tables.
