What we did was buy a boat load (200+) of these and unsoldered the XLR connectors.
We then epoxied 2 of the connectors upside down (pins up) where the XLR used to be, then ran short jumpers to the data(+) and (-) and power down to the phoenix connector on the left.
I wish I took pictures of our boards BEFORE I enclosed and sealed them.
I'll try to get some soon
here is a link for 50 of them
