So I have an ETC Insight 3 that I want to control a whole bunch of conventionals with, and, as much as I hate it, an Elation Pro Compu dongle to control a couple movers with. The only problem is that they're all run down the same dmx line and I don't want to have to run another line. So my question is, on the Insight, theres a DMX In Port. Can I run a dmx cable from the dongle, to the In Port of the Insight, and then Dmx through the chain of dimmers and movers? Besides the 3pin-5pin cables I need to do so. If not, is there another way, or another piece of equipment I can purchase, to accomplish the same thing?
