Addressing via DMX/RDM
RDM (Remote Device Management) is an open and bi-directional protocol standard for DMX-controlled devices. The
permanently transmitted DMX data flow briefly pauses (several milliseconds), and an RDM data package (message) is
sent directly to a subscriber. The subscriber evaluates the information in the data package and sends an answer (semi-
duplex) on the same line. Targeted polling to a subscriber via its UID (Unique ID) prevents several subscribers from
answering simultaneously.
The protocol makes it possible to receive status information about a unit or to change configurations on a unit. Chang-
ing the configuration means, e.g. changing the DMX address. The prerequisite for this function is a RDM-compatible
controller. Read the corresponding operating instructions
