Step 3Dimmer Racks
The dimmer units take the 0-10v signal on a 5pin DIN connector (1 pin is ground the other 4 represent the 4 channels) and they take the DMX signal on a 3pin XLR connector. DMX devices can be daisy chained as each one has its own id set, if you look closely at the picture above you can see an orange cable (0-10v signal), a purple cable (DMX daisy chain link) and a yellow cable (DMX in from the DMX controller)
Here are some more pictures of the dimmer racks:
Across the front of the rack you can see a bundle of 1mm T&E cable, each one of these goes to a different lighting location throughout the house. Quite simply this cable runs from the dimmer straight to the light fitting in the ceiling, this does make the wiring of any light fittings very easy, as there is just a single cable to contend with. These cables are connected to the dimmer racks using male IEC connectors (the male version of a kettle lead)

So each of those plugs that are plugged into the dimmer packs are a separate room?

yes indeeedy! Well I do have a kitchen diner, so arguably one room, but generally yes, those cables go off to each ceiling rose in each room, I have one spare. Thanks for your interest Dan

That is so innovative. Bringing DMX where mostly used in theater and commercial applications into the home and automating it. Being an electricianI think this is awesome. One thing I wonder is, is each dimmer pack on its own circuit and if so what is the amperage rating.

Yep, each is on it's own circuit. The fusing is a bit confusing... My main consumer unit has 6amp circuit breaker for each circuit, but the dimmers have an integral 16amp circuit breaker. Then each output is fused at 5amps with a little 20mm glass fuse. I have at most a few hundred watts of lighting on each dimmer, so the 6amp circuit is plenty, however the dimmers are good for about 1kw per channel I believe, but this is due to their stage/theatre origins, I'd never use that much at home.
