Hello, and Welcome to ACL. If you like to talk lights, you've come to the right place. A lot of friendly and knowledgeable people waiting to talk and take any questions you might have. You might want to read the 101 manual to start. http://auschristmaslighting.com/wiki/AusChristmasLighting_101 Stop by chat and say hi.
Thank You for your prompt reply. I apologize for not posting the complete info. The arches are 6'-6" X 3'-3" straight length is 10 FT (1.98 M X 1M straight length 3M). I have been reading about the E681 and I'm planing to buy one or two and use it for the next Mega tree for next year (I still have to do more reading though). But for this year I was thinking to use the controller I posted in the previous post since I have already bent all my 3/4" PVC pipe. I have not bought the controller/s and the LED strips since I was not sure if I can use one controller/3 arches or I have to buy 3 controllers, one/arch. I already have LOR S3 installed. I just started the Christmas display 2 years ago with 3 boards LOR CTB32LD and now I decided to take it to the next level. I have been reading about most of the DMX controllers and I figured, I might be able to get the arches going for this year....maybe.
