As for hybrid mode possibility; I have never selected that as an option. Please read on however...
I've been thinking about this for awhile. I should have taken a hint from Arw01 and tried Xlights but it didn't dawn on me until RJ chimed in. I have been using LSP to test my lights all along. I went to Xlights to test.
First I tested my string with a pixelnet dongle - got lights to function - now I know my controller and SSC is correct.
Second, I tried my EtD - and got lights to function! However...they seem to be functioning in HYBRID mode. Honestly, I have never selected hybrid mode. Never considered it an option. About 6 of the nodes in my 128 string don't turn on. However lights on either side of these nodes do turn on.
Third, I tried my EtD with LSP and got the same output from LSP.
So, using what appears to be a functioning EtD, I tell myself lets try to program my SSC with it using the Utililty and get rid of hybrid mode. SSC has program jumper set. Hit Transmit - I don't see flashing lights
I am using the SS Utility version that has "grouping."
I put the jumper back to operate and test lights and no lights.
I'm going to reflash my SSC and try to get things running again.
Thanks guys, I feel like I'm getting closer.
