Re: CBUS Control Bus wiring topology

[Neil Fuller <neil.fuller@xxxxxxxxx>]

Thanks Ben (and others).

I'm still undecided!!

I can see that the easiest and certainly the cheapest method is to daisy
chain but as I come from a service and maintenance background, I'm
always thinking about future fault finding when I'm planning an install.

I guess as long as I document cable runs etc, any faults should be
fairly easy to locate.

If I home run all the points, presumably, I'd patch to another patch
panel where the patch panel punch downs are commoned together and I
would take a single patch cable to the CBUS panel? I guess I could use a
Krone block to do the same thing, although it would all be a bit of a
mess in the box!!

Before everyone asks, yes, I'll take pictures!!

Cheers

Neil
