Not to insult or assume anything ... but in case someone else reads this and gets ideas....
I'd be careful using instructions from holidaycoro and then applying it to SSC connections, because a lot of those are dealing with the 4 wire RGB modules and regular DMX controllers, not SSC 3 wire modules and SSC controllers.
Again, I love holidaycoro and they have super instructions, but I'd be careful ... because what works for smart strings, versus more regular DMX and RGB modules ... isn't always the same ... and I'm sure dmoore would agree to that end.
Others, if your just getting started with smart strings ... the TM1804 tester that Ray Wu sells is great ... and worth the extra $20 investment, IMHO. Esp. if you don't have all your SS ready to go.
