I do want to add a bit to this thread. I think that the IBU2U manual is sort of lite and that for a first-time user of IBU equipment. like I am, it would be a good idea to download and read the normal or old IBU2 manual and have it and the new IBU2U manual on hand. ALso, I encourage you to ask Ian lots of questions....I did and it helped me greatly; Ian was/is great at helping me understand the IBUs. While I am still technically still awaiting delivery - should be here this week I think - I really feel I understand the system and I am comfortable with what I need to accomplish in its install.
And, one more note with regards to the 16 Gb micro SDcard. In WIndows 7 you should NOT try to "Quick" format anything in a FAT format, so uncheck that option and let it take the time to do a normal, full format.
