[SML] DMX cable 2-into-1

[David Fox]

Any type of DMX 2-fer makes me really twitchy because each universe should have its own data common line and you can't do that with a 5 pin XLR. 

Using a single 5 wire cable with a shared wire to act as the Data Common for both  universes means that your common is now doing double duty and splitting out of the daisy chain topology.  

Even if the wire used between 2fers contains 2 independent pairs each with their own shield like Belden 9729 or TMB's PC244Tproplex cable, you still have no way of connecting each of the commons.  

Just my .02
