My new S16 is setup and sync'd to the X32 at church. I've had my X32 for about a year, and have been real happy with it. I had posted my "plan" to install a S16 a couple of months ago to add soem inputs on stage, and got some good Ethernet wiring advice. Following that advice, I pulled Standard Cat 5e wire in the walls, and punched down into RJ-45 wall jacks just like my Ethernet for PCs. Standard Cat 5e Ethernet cables connect the X32 and S16 to each wall jacks.
It took some time to correct a couple of my punch-down errors, but once I had fixed my errors, the S16 sync light turned green, as did the AES50A light on the display. The S16 is on stage and communicating with X32 up in the sound booth.
Now I just need to figure out the routing options with the S16.
