Success! Thanks to everyone for the guidance. I changed two things. One of them, I know had to be done. The other one, I think needed to be done. I first was thinking of chadskeys information that the LOR box needed to be unit id 1. I had made an earlier attempt to do this, but had done it wrong. In the Hardware Utility window, there are two boxes for changing ID. One of them is for a new unit that has never been assigned. I incorrectly used this one - entered 01 and save. But it obviously didn't change the ID. I went back on chadskeys advice and finally realized it was set to ID 7. I used the correct box and changed it to 1. Then, in reading several threads last night, I saw someone mention the E131 setup in the Falcon setup. I had never set up a new universe to point the serial port to. I only had the 32 Falcon universes defined. So I added universe 33 and pointed DMX output #2 to that universe. Finally, I went back to the Xlights setup and removed the LOR box entry that I had in location #1 and made a new E131 entry at location 33, defining it with 16 channels. I pointed my test AC lights to universe 33, channel 1 and it worked! I also had an RGB channel populated with a frame and the marquee effect. Both types of lights worked at the same time.
This was a real learning experience, but I expect I will find myself in a similar ditch down the road. So, thanks to everyone for your input, and I'm sure I will be back

BTW - Ebuechner, my better half had set up a dinner event last night that I didn't know about. That's why I didn't make it to zoom. I want to sit in some time, even if I don't have a specific question at the time. I know I could learn a lot. Do people sign in just to listen and learn?
