Couple of things here...
LOR to DMX translations...in your case...go like this
LOR A0 is DMX 1
LOR A1 is DMX 17
LOR A2 is DMX 33
and so on...
Make sure the LE's have the DMX addresses set correctly.
If you are using S2, does the status light go solid on the iDMX when the sequence editor is open? Make sure you have "control lights" checked under the tools option. If the boards work correctly in hardware utility, they will work with the sequence editor, you just have a setting off somewhere.
RJ, A0 is the numbering system LOR (and most commercial companies) use. It is based on the hexadecimal system. IDK, I was never good at algebra either.
