I'm upgrading sound equipment in a school. I connected my SL32 Series III to a 16R for a meeting using a CAT5e wire that is run through walls and it worked great. I tried that same connection today but using the SW5E and it would not connect. Using a short CAT5E cable right at the switch worked but not when I used the 200' line that was installed when the building was built 10 years ago. I knew the risk of using existing wiring which is why I tested (very successfully) point-to-point before purchasing more gear.
I'd appreciate any ideas you my have.
