Sorry for my ignorance.. brand new LOR user.. So to connect this to an existing LOR system using CTB-16s, do I need the DMX XLR connector?.. or does it just sit in line with the CTB-16s and add 150 channels to my sequences? Also.. in the video it says it can be cut.. so to make 2 arches 10ft apart.. can I cut it, then put in an extension cable to join the 2 halves, then just program it as though it was one piece? **Ignore.. just read the quick guide!.. explained it better than the manual!
