Thanks Scott,

On the physical layer timings issue, it doesn't look a lot different to Standard DMX except for responses have a 176us min break as opposed to 88us, and there are some max times now introduced which DMX were probably ignored.

I found the following in the Enttec Sniffer Manual:

PACKET TYPE MIN TIME MAX TIME
DMX 512 - Break 88 us
RDM Any - Break 176us 352us
RDM Discovery Response 176us 2.8ms
RDM Controller Request 3ms 1s
RDM Controller Discovery 5.8ms 1s
RDM Responder Response 176us 2ms

Anything else to look out for?

Paul.
