Really Basic Universe Math Question

[danj]

Here's the way I have my channels setup in my E682's
These strips are 5m and are 30 LED/m, 10 IC/m.
Now that I am laying this out again, I realized that I have the second set of sockets setup incorrectly--I set the second set of sockets as if I had strips in series, but I DON'T)--so that might be the problem....   Doh.  I will reset this tonight and try it again; maybe that was my problem....

12V E682 setup (only used for the megatree5m model)
First set of sockets start at universe 7 channel 1 (I changed last night as a troubleshooting measure).  I have these setup with a 100 pixel length since I have two strips in series
1-1--strips 1&2 in series
1-2--strips 3&4 in series
1-3--strips 5&6 in series
1-4--strips 7&8 in series
Second set of sockets start at universe 9 channel 181 (I just used the next channel after the last channel for the first set of sockets)--I have these setup with a 100 pixel length since I have two strips in series
2-1--strip 9
2-2--strip 10
2-3--strip 11
2-4--strip 12
The third set of sockets start at universe 11 channel 361 (again, used the next channel after the last channel for the second set of sockets)
3-1--strip 13
3-2--strip 14
3-3--strip 15
3-4--strip 16
The fourth set of sockets start at universe 12 channel 451
4-1--strip 17
4-2--strip 18
4-3--strip 19
4-4--strip 20

The troubleshooting continues...    Today I have setup all 20 of my "megatree5m" strips with the full setup including power injection.   I have used SACNView to generate test signals pixel by pixel and I am 100% certain that my setup is correct and all strips are hooked up to the correct sockets on my E682.   I verified that both my xlights model info and my E682 setup are consistent with each other--both start at channel 3571 and stop at channel 6570.  I am going to hook up my second E682 and drive my megatree3m model and see what happens there.   What I found using the xlights test function is that when I test all channels of my megatree5m model, the first two universes never light up.   I just checked what is being output by xlights when I have all of my megatree5m channels selected (using SACNView).  SACNView shows that xlights is generating test signals in universes 9 thru 14 instead of 7 thru 12 as expected.   One other thing--when I select "all channels" then all of my megatree5m channels light up when the test signal is generated--I checked with SACNView and all 15 universes are generating the test signals, which is right because that's how many I have selected in the setup tab.  Any ideas?

In the setup you gave me you don't have a universe 1.  Channel 3571 starts on Universe 8 but below it sounds like you think it starts on Universe 7.  Maybe you need to fix the setup to move all the universe numbers down one or change your E682 setups to expect them how you configured in xLights.  The advantage of how you do have them in xLights is that your output numbers match your universe numbers.

Thanks again Gil.   I adjusted my universes in my E682 screen to start at universe 9 and now all the info is being pumped to my pixels.  Doh on my part on 3571 starting universe 8 not 7.....
