Question:  For users connecting a Concert Server via a Delta 1010 audio interface back to a Matrix Frame (Matrix +3 or Eclipse Matrix) how do I make the wired connection? 
Answer:  The wired connections are made from the unused Matrix +3 or Eclipse frame MVX ports out to the Delta 1010 interface TRS 1/4 jacks.  The Delta 1010 has ¼ TRS jacks (labeled IN and OUT) for each channel (1 thru 8) so to make a cable with an RJ45 connector, use a CAT-5 patch cable and cut off one of the RJ45 connectors.  Then wire up two ¼ TRS phone plugs to this end using the wiring scheme show below (blue pair for Eclipse frame output via tip and ring) (green pair for Eclipse frame input via tip and ring).  If a shielded CAT-5 cable is available then use the drain wire and connect it to the shield connector on the TRS phone plugs.
