CCR1's can't be seen in Cosmic Color Devices Posted November 25, 2018 Thanks Dennis I discovered I had a cabling issue. I tested each Ribbon in the HU and they were all working fine. This is very strange because they do not work running them in a sequence or in a Show that I put together. I even ran a playback file in a test Show from last year and it didn't work. The other lights in other networks all worked fine.
