    Default I need help!

    Okay, I'm pretty new to all this stuff and I've extensively researched the alternatives or what I want to do. You wouldn't believe how difficult it is too find installation details and stuf. :?

    OK - so I inally decided what I needed and this was a Comfort system with C-Bus integration. I then intend to piggy-back IR signals on the Linn Knekt system.

    Basically, what I want is some kind o simple explanation on how to plan the C-Bus side o the system. Yes, you can get overly complex system/wiring diagrams from the C-Bus site but these don't say stuff like plug unit x into unit y, then plug unit y into.....

    So basically what I'm asking or is help of somebody thats implemented C-Bus. I think I've sussed the connecting of the lights to the dimmer mods but I'm not 100% on the CAT-5 wiring.

    BTW - has anyone noticed hw much the pink C-Bus CAT-5 is? surely pink plastic can't cost that much more than grey!

    Hi Ric

    The CBus Shop has just added a resources page that links to training PDFs etc. Look here...

    Thanks for the info!

    I had already seen some of this and the rest has given me more of an idea.

    The one thing I'm struggling to find though is how to wire the light switches in.

    I intend to use C-Bus keypads so these will be connected using CAT-5. It's just where to connect the other end of the CAT-5 to. I understand that the C-Bus mods daisy chain together using CAT-5 and RJ-45s but how do you introduce the switches?

    Light switches, input units in C-Bus speak, are wired to the C-Bus network in the usual way. ie. They are connected to the two-wire C-Bus network just like any other C-Bus modules.

    A C-Bus network can be wired in a star, daisy chained or a combination of the two methods (but not in a closed loop) so it is very flexible.

    To expand on Kwong Li's reply:

    1. All C-Bus units (wall-switches, dimmers, whatever) are linked together to form a single network. The easiest manner of doing this is to simply daisy-chain the units together: however, unless you have planned the installation really well, you will probably end up with a number of interconnected stars.
    2. The wall switches / PIRs / etc units (the input units in Clipsal-speak) send messages on the network. These units don't use RJ45s - they have screw-down terminals like any standard wall-switch. Since polarity is important the terminals are marked +/-.
    3. The current to the actual lights is controlled by the dimmers & relays (the output units in Clipsal-speak). The output units respond to the messages on the network, switching the current accordingly. These units normally use RJ45s, though the older units use screw-downs.
    4. The best method of wiring a house is to install a second distribution board specifically for the Clipsal dimmers / relays. The wiring for the lights would then run from the dimmers / relays to the light fittings.

    Re the 'pink CAT5'. You can use standard CAT5 cable. However, be sure to keep to a colour coding throughout your house: running mains voltage on a LAN is not recommended <g>

    Re the Knekt: Piggy-backing IR signals on the Knekt could take some work, though is not impossible - you may also want to consider using the C-Bus network to transport the IR signals. The main hassle is the IR codes - an IR reader is very handy - and expensive. I did all of my own work, then paid a systems integrator to read & install the codes for my Somfy blinds.

    Finally, if you go into Clipsal seriously, you should consider their HomeMinder. I control lighting / swimming pool / geysers etc using one. It has a built-in X10 interface, so you can also control X10 units when necessary. The HomeMinder also has a two-way telephone interface (as an optional extra).

    Thanks soooooooooooo much for that!

    It's strange that I couldn't, after hours of trawling the net, find a nice simple description like that.

    That's the sort of idea I had in my head but only from reading all the technical docs. This clarifies everything quite nicely.

    My pleasure. I must say that I am very happy with the Clipsal system - I simply couldn't have wired the 160+ <g> lights in my house using conventional wiring. If you decide to go ahead with Clipsal let me know - I have a few tips that I can pass along.

    Rowan - any chance of some pictures of your install?

    Would love to feature it on the site.

    Thanks

    The builder's work isn't complete as yet, but will send you some when all is finished.

    Thanks. But take plenty of "work in progres" pics too!
