I hate to disagree with you, but I don't remember there ever being a LOR section on the site and I've been here almost three years. LOR is a commercial product/protocol and we do not officially provide any support.
There are numerous LOR users though... And many questions get asked and answered. Look in the porch for LOR stuff.
As for pixelnet, the EtD just receives standard e1.31. E1.31 universes 1-8 = pixelnet universe 1, 9-16 = pixelnet universe 2, and so on...
There are at least three versions of the EtD firmware with the differences being which 4 pixelnet universes are supported - 1 thru 4, 5 thru 8, and 9 thru 12.
I don't know if the EtD expects all 8 e1.31 universes in a pixelnet universe to be updated together or in a particular sequence.
