Thank you very much! Your post helped me get my comp to communicate with both of my Pixie 8's. However, I cannot figure out how channel config. Two pixie 8's, Unit 1 running 4 Arches, Unit 2 running 3 Wreaths. (Do to placement in my yard, and allowing for further expansion, that is why there are separate units running a few props.) Under current config Unit 2 is running off of the Arches sequence, not the Wreaths. Based on the above original post, Unit 1 Arches start at Unit 1,2,3,4. I skip 5,6,7,8 and star t Unit 2 Wreaths at 9, 0A, OB. Any suggestions on a remedy?
