RDM and Dimmers

[Paul-Zero88]

Hi All,

We’re starting to look at implementing RDM in some of our dimmers and controllers. However the RDM specification doesn’t seem to include any definitions for setting up the following on dimmer channels:

- Preheat
- Topset
- Curves
- DMX Fail behaviour (hold, fade to black, fade to preset)

Since these are pretty standard dimmer features from many manufacturers, it doesn’t seem to be the right thing to do, for us to use manufacturer specific definitions to implement control of these features. The RDM specification defines much for moving lights (prism, strobe, pan, tilt etc), but seems to overlook good old fashioned dimmers.

Any thoughts on the best way to proceed would be welcome.

Thanks,
