Hi Everyone, I am a NEW Player in the C-Bus Community Forums. Our home was 100% C-Bussed when built 14 Years. Full installation done by Licensed Sparky & C-Bussed by Clipsal Accredited Installer. The Network currently works well. What I Now Want to Do I want to "Add" two NEW circuits to the existing Network and Programme these two NEW circuits accordingly. Basic Info About My Existing Network The existing network consist of Many Dimmers & Relays of varying sizes. Numerous Switches & Scene Controllers make up the Network. A C-Bus2 Network interface [CNI] is also incorporated into the Network. A PC with the latest Windows operating system is also permanently hooked up to the Network. From the PC the home Lights can be operated without any issue. [Although we never use it]. About Me Pretty up there with computers but in the past 12 years heavily into Apple Computers. Average with Windows PC but I can get by doing a Google search and completing the task at hand. Have always been a good thinker and handy at fixing minor things around the home. I never take risks, I always research my subject.… plan well and execute the task. Task At Hand - Add Two NEW Circuits To Existing Network The C-Bus "High Voltage" side will be done by a Licensed Electrician. [No Exceptions] The Licensed Electrician knows the C-Bus hookup…. but he knows nothing about programming of C-Bus. No. I am NOT Interested in getting someone out here to program a C-Bus Switch. Currently unemployed and also want to learn to do it myself. I want to start learning to programme the switches etc myself this is the whole idea of this project. I have a few Spare 1, 2 & 4 Gang switches that I would love to know how to program. Tons of Cat6 Cable - Crimping Tool - Connectors including the Pink Shielded type etc etc. Fully conversant with 568A - 568B - Straight - Cross Over - Rollover & Loopback etc. I am confident and I will be doing the low voltage side of the lights in the Garden area. Fully aware of Voltage Drop - Wire Types - Wire Sizes - Conduit requirements & Lights in concrete canisters and terminations etc etc. The two NEW Circuits will be connected into an Existing Dimmer in the C-Bus cabinet. The Existing Dimmer has two Unused channels…. We plan to use them. The Maximum load on each of the Circuits is within the allowable limits of the Dimmer. [This has been checked and confirmed]. Your constructive advise on  What I need to look out for  ALL needed Equipment for Programming and the Hook up sequence.  What I need know and do safely to complete the programming  How to bring these two NEW circuits "Online" into the Network  Any other valuable info including "Tips" & Pitfalls….. will be very much appreciated. I would love to programme one of those spare 1, 2 & 4 Gang switches that I currently have in hand before I start jumping onto the Existing Network. There are several Wall Switches currently within the home that have a few "Unused" "Key Groups" !!! Thanks in advance.
