RDM

7.1 RDM - What is it?

Remote Device Management is a protocol that sits on top of the normal DMX512 data standard.
DMX512 is a uni-directional protocol which means that the data flows in one direction – from the control
desk to the lights.
With the addition of RDM, the DMX512 system becomes a bi-directional (half-duplex) system.
The controller is able to send out a question to devices on the wire, which can then respond with an
answer. The messages within the protocol cover all the everyday tasks a lighting system manager
incurs – setting DMX addresses, modes and other configuration tasks, plus monitoring sensors, usage,
status messages and fault finding.Think of an RDM transaction as a conversation – the lighting desk
says 'tell me your DMX address' and the fixture responds with 'my address is 032' . This is known as a GET
command. Next the controller can send a SET command, such as 'set your DMX address to 065' , and
the fixture can respond to acknowledge this change. In this way, through GET and SET commands and
responses, the RDM protocol allows a control desk to modify and monitor the DMX system in ways never
possible before.

7.2 RDM requirements

To use all MERLIN RDM functions, your device must be normalized: ANSI E1.20 - 2010 ( & if possible)
ANSI E1.37 - 1
