R Ricky Sitts New member Sep 1, 2008 #1 Quick question as to how the WRDOWY17 sensors are assigned their order. Is the unique serial number used, or is it something else? Originally I thought it would be the order they were plugged in, but this dosen't seem to be the case. Crystalfontz LCD BlogLooking for additional LCD resources?
