Re: Built my E681, need help with 1809 pixels
I've got an E61 and the same strips from Todd you mention and I configured the controller as 1804 (the fast version) and hooking them up with the appropriate power and by deault it will cycle through a test sequence that's built into the controller so you can see some minimal blinky flashy without having to get Vixen involved. You can also configure different test sequences in the E681 as well to run red, green or blue chases - I believe the test sequence numbers are 04, 05, and 06 respectively. I also had to adjust the RGB order for the pixel strips, I don't have access to the controller now to tell you what the actual order is but it was apparent that they weren't RGB when I ran them through the test sequences at the same time as the pixel string.
2015 Plans: More pixels, add more Komby radios, and weld new props!
