Hi Scott,

I understand your point but please understand that I am somewhat restrained with what I can and can't write here in the forum. I am not allowed to mention any specific equipment details. It is not my decision but somehow I can understand it.

The start code I see is indeed 0xF0. I see it on professional equipment that is for brand new and for sale. These are not prototypes.

Does this mean that new responders should listen tyo 0xF0 and 0xCC for a start code?

When was this transition made?

Kind regards

There is a lot of product out there that was built to draft versions of RDM. We intentionally decided to not choose the official RDM Start Code until after the Standard was finished. This has helped keep the draft versions from creating problems with the final version of the Standard.

There are no RDM police to control when someone states something is "RDM" or not.

What Start Code did you see the traffic under? 0xF0 was the prototyping Start Code we used in all the draft documents. The list of registered Start Codes can be found at:

Again, if you can provide specifics on the gear, then I might already have information on what protocol or version of RDM is being used.
