RDM V1.0 and Art-Net - E1.20 RDM (Remote Device Management) Protocol Forums

sblair · July 23rd, 2006

The Art-Net implementation of RDM was done based on a variation of several early drafts. I would advise against coding to the draft versions and instead wait for Artistic Licence to update to the final version of E1.20.

The Art-Net implementation was done using the prototype Start Code SC_RDM of 0xF0. Now that RDM is actually released all RDM communication is done using the official 0xCC Start Code.

SC_SUB_MESSAGE has always been present and always been 0x01. You will find a numerous incompatabilities and differences between the draft version that was implemented in Art-Net and the final version that has been released.

Again, I would encourage you to only code to the release version and await the update from Artistic Licence to the release version as well.
