We have a control console, shoebox dimmer and two scroller power supplies, all of which are 5-pin DMX. Rental company is bringing in an additional (8) dimmer packs, some of which are 5-pin, but some apparently will be 3-pin. What is best way to combine these all together? Can they all be on a single 5-pin DMX string with in and out "adapters" at the 3-pin devices? Or is it more complicated than that?? Thanks.
