Hi all I got this free.... http://www.gardensandhomesdirect.co.uk/Garden/Arches-and-Obelisks/9ft-Fibre-Optic-Outdoor-Archway.html I plugged the 2 x 4.5VDC-240VAC transformers (one for each side of the arch) into my 240v LOR machine. Unfortunately it wouldnt go unless I pushed a little on/off button. So I cut out the button expecting it to be easy peasy, just wire up the 3 internal wires, Red/Yellow/White. Unfortunately that wasnt the case. I had to get help in chat this morning and BarnabyBear helped me out, figured out which wires did what. He thinks that hooking it up to the DC48 is the best bet as opposed to the 240v LOR which is what I originally wanted to do. Following various test we have established the following: * It is powered by a 4.5V DC supply. * The arch has a 3 wire connection – Red live – White ground – Yellow momentary switch on/off. Can I connect the 4.5V Yellow switch wire to an input and the White ground to a DC48 to control the arch? This will be powered from an independent power supply. Which, if possible, terminals would I hook this up? I also have a LOR 16-chan DC board as an option as well. It will have to be sequenced differently to others in that one filled square will turn it on....the next filled square will turn it off (LOR S3). Here is the arch and plugs etc. The original on/off button that was approx 20cm from the adaptor/plug.

In the box is this board. Any and all help would be much appreciated.
