If your dealer was on site, they should have left you with either a working
system, or sent in more parts than just the paradigm
processor for repair.
in sACNview, you should see your
ion as a
sACN source on
universe 1(assuming that the
ion is turned on, and you have lights patched in
universe 1) - I would recommend opening a show file that you know worked before the
power issues, so that you know the patch isn't the problem.
It's possible that your
dimmer racks are using edmx rather than
sACN - look in the patch
screen on your
ion(in a known working show file), and see which boxes are checked under "interface" on the right side of the
screen.
ETC tech support can also help you with this - they should have the install drawings and configuration files, so they won't be guessing at how your
system is set up, the way we are.
