I have a Renard SS24 that I've assembled and have working fine via USB/Serial adapter from Xlights. Then I got an E1.31 bridge that I assembled last night. It's working fine, and I can talk thru it to the Renard from the text mode in Xlights after setting it up as an E1.31 device.
However, I can't get the lights on the Renard to function when doing a quick sequence test (which was working when I had it connected via RS-232).
I've attached a screenshot of the very simple test I'm trying - basically using the 1st 4 channels on the Renard in a simple on/fadeout sequence. When I hit 'play' I get the music just fine, but no output.

The only other thing that changed is I was using an older version of Xlights from around Feb. previously - I figured I'd upgrade it while I was messing with the E1.31 bridge.
Any suggestions of what to try? I've gone thru a lot of tutorials but haven't been able to find any clues to this issue.
