Pixel Strip Arch help

[TheSignGuy]

So I'm trying to add 4 pixel arches, I just don't get how to make them in visualizer.

Using only LOR S4.4.6 (no SS or PE) and I have a pixie 8 using 2 ports (1 and 2) my arches are ribbons at 60 pixels per arch each. So I have 120 pixels on port 1 and 120 pixels on port 2. When I go to add them with the "wizard" I can only get 50 pixels to show up, If I use the DMX option (where I can add 60 pixels) how do I config my channels to talk to SE using the RS485 adapter????
