RDM functions
20.1
What is DMX?
The abbreviation DMX or DMX-512 stands for "Digital Multiplex" This is a standardised digital transmission
protocol used in stage and event technology as well as in many Oase components.
20.2
DMX / RDM
This unit supports the DMX protocol enhancement RDM (Remote Device Management). RDM is a bi-
directional protocol standard for DMX-512 controlled units. The protocol makes it possible to receive status
information about a unit or to change configurations on a unit.
20.3
How does RDM work?
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.

RDM monitor
The operating status of the devices can be monitored in the RDM monitor of the controller.
